How an ancient art, a relentless pursuit, and a partnership forged across continents gave rise to a breakthrough in modern meat processing

By Eben van Tonder, 14 June 2025

Introduction

Some stories take a year to unfold, and then some stories take a lifetime. This is the story of reformed bacon, not just as a product category, but as a calling. It is the story of a dream pursued over two decades, through failure, loss, and rediscovery, until one day, under the heavy clouds of a Nigerian storm, it finally came together.

The Difference Between Formed and Reformed Bacon

In the world of processed meats, formed bacon refers to bacon shaped into regular logs using moulds or grids. It’s a standard industrial technique. Reformed bacon, however, is more ambitious. It’s about taking small pieces of meat, trim, offcuts, fragments, and fusing them into a single, cohesive log that behaves like whole-muscle bacon. Done well, it holds together in the pan, slices cleanly, and delivers a sublime balance of fat and lean.

What most don’t realise is that the science behind this is ancient. Long before binding proteins were studied in labs, the method of pressing and binding meat was used in European peasant kitchens and eventually codified in the monastic traditions of Austria and Germany. The basic process behind pressed ham is nearly identical to that of reformed bacon. It simply involves longer cooking. Originally, the tools were rudimentary: wooden forms, knives, mortars, and pestles. Today, we have grinders, emulsifiers, stainless-steel moulds, and industrial smoking chambers. But the essence remains unchanged.

A Personal Obsession Begins

My own obsession with reformed bacon began in the early 2000s. I was convinced that it was possible to create a perfect restructured meat product: one that wouldn’t break apart when removed from its packaging, that would hold its shape in the pan, and that would taste like something better than the sum of its parts.

Oscar and I had just launched Woody’s Consumer Brands. Through the support of Profet, I travelled to England for almost a year to collaborate with British producers and explore the technologies available. We had the drive. We had the vision. But the project was a failure. Not a single one of our objectives was met.

Woody’s shifted to producing ordinary bacon at scale. But I never abandoned the dream of reformed bacon. Or rather, it never abandoned me. Over the following years, I delved deeper and deeper into the science, examining protein mechanics, pH effects, amino acid interactions, and the roles of heat, cold, and mechanical action. It was an overwhelming body of knowledge. I had no idea how much I’d need to master before I could return to the work we began in 2011, when I first officially launched the reformed bacon project.

A Turning Point in Austria

The turning point came with Christa Berger. An Austrian trained in cultural anthropology, with a deep respect for both ancient traditions and modern food processing, Christa had grown up in the Alps. She developed a remarkable understanding of meat-curing heritage.

It was Christa who introduced me to the archives and practical knowledge held in Austria’s monastic institutions, repositories of meat science techniques passed down and preserved across centuries. We began working with the Almi spice company and their exceptional team of young scientists. The project began to take shape again. Concepts I had explored 10, 15, even 20 years ago began to resurface and combine in new ways. Christa and I would speak every evening, working through technical hypotheses, testing theories, connecting dots.

In Nigeria, where I had the freedom to work beyond the gaze of corporate meat processors, I started testing our emerging theories. A week ago, I told Christa that while I liked our direction, I fundamentally disagreed with a core mechanism in mainstream reformed bacon theory. She listened and calmly replied:
“Of course, the theory is wrong. A better approach would be a, b, and c.”

That night, the solution was born.

Breakthrough in Nigeria

The next morning, I implemented two variations of Christa’s insight. One of them worked brilliantly. For the first time, the product held. I wasn’t focused on colour or flavour development! This was about binding, weight loss, and slicability. It needed to perform like pressed ham: sliceable on a ham slicer, at ambient temperature, with minimal structural loss.

It required more attention to detail than any other product I’ve ever developed. Every single factor, from hydration technique to mechanical treatment, had to be re-examined and perfected. But finally, after 23 years, I had something I was proud of.

The Cost of the Journey

Last night, I became sentimental. I thought about my mother—her descent into dementia and Alzheimer’s during these years, and her final days, which I missed while travelling in Nigeria. I remembered the last gatherings with my brothers and our children. I looked at photos of the kids growing up.

Tristan and Lauren once joked that they’d inscribe on my gravestone:
“Our Dad Tried.” They grew up watching me return home week after week, having failed to produce the breakthrough I was chasing.

When I met Christa, our earliest conversations were about salt and ancient curing. I once told her that the structure and clarity she brings into my life might be the key to pulling together the strands of both my work and my identity. That prediction turned out to be true. A woman raised in a farming village in the Alps helped me unlock what I couldn’t in 23 years of effort.

And yes, as we laughed last night, this journey has been the equivalent of a university degree—because oh, the things I have learned.

A Slice and a Storm

This morning, with torrential West African storms pounding the coastline, I stood in the factory and had a warm, flavourful slice of reformed bacon for breakfast. I thought about the failures. I thought about the friendships. I thought about the science, the monks, the factories, the years. And I smiled.

Because it was worth it. Every single step.

Mornings on the Farm

The day started early on the farm in the last foothills of the Alps in eastern Austria. My parents got up, dressed, and went straight to the barn to milk, muck out, and feed the animals. In winter, when it snowed and the icy wind whistled down from the mountain, they wrapped themselves in warm clothes and enjoyed the warmth of the animals in the barn. We had about 25 dairy cows, several bulls, and a few calves, as well as pigs, chickens, and a horse.

Helping Out as Children

When we were old enough, we helped out when we didn’t have school. Our tasks included grooming the cows, mucking out, sweeping the aisles, cleaning the feed troughs, and refilling them with fresh feed. Grandpa accompanied us. In the hayloft, straw and hay were stored, which we could throw through a hole in the floor into the aisle in front of the cattle using a pitchfork. Once, my sister fell through such a hole and broke her leg.

Evening Chores & the Taste of Bacon Bread

In the evening, it was our job to fill the milk from the tank into cans so it could be taken to the collection point in the morning. Afterwards, the milking room had to be thoroughly cleaned with a broom and water jet. By the age of 13, my little sister, my two-year-older cousin, and I could already milk and handle all barn work independently. After that, the bacon bread tasted especially good.

Early Rising & School Snacks

Usually, my parents were in the barn by six o’clock at the latest. We children also had to get up early because our farm was on a mountain, and we had a long way to school. Grandma helped us get ready for school: washing, dressing, combing, and braiding our hair. She also prepared our school snack, which, as you might guess, was often a bacon sandwich. She cut the bacon into fine rectangular strips, salted and peppered them. At school, I had to be careful while eating because these small bacon strips wanted to fall out of the bread. When my parents came back from the barn, after about an hour and a half of work, there was coffee, a buttered slice of bread, and often homemade jam, but by then, we were already on our way to school.

Daily Work & the Importance of Bacon

Then they went back out to continue working in the fields, the forest, the orchard, the hayloft, or the barn. The work was hard and physically demanding. At half-past nine, they came back in for their second breakfast: homemade bacon, freshly baked sourdough bread, and cider. Especially during heavy labour, bacon was indispensable, not only tasty but also strengthening. As luck would have it, the mailman arrived at exactly the same time in the morning and enjoyed a good piece of bacon and a glass of cider with the family. Bacon was just a part of our daily life.

Meals in the Forest & Long Working Hours

When my father went into the forest with the men, which often meant they wouldn’t return until evening because some of our forests were high up the mountain, they took their provisions with them. Bacon was always included. In the afternoon, my mother and we children would follow and bring them hot coffee and a pastry—like a nut cake—to the clearing. Generally, the men worked in the evenings until they were exhausted – in the summer, always until there was no more light outside. That could be until eleven o’clock at night. Later, my father also ran a custom threshing business, and since the combine harvesters had headlights, he could work even longer. I remember that he sometimes came to our beds completely dusty after midnight, very hungry and exhausted, to quietly say “Good night.” But he was glad when all the machines worked, and he could successfully complete all the day’s tasks. My mother always waited for my father until he finally came home, and then she prepared a small supper for him and the hungry drivers, like an omelette with bacon.

Learning Household Skills & Sunday Meals

Young girls usually attended a domestic science school during their compulsory schooling to prepare for marriage. But since my sister wanted to become a kindergarten teacher and I wanted to become a teacher, we attended a higher school. So, Grandma and my mother decided that we had to learn at home what we missed in household management at school. Every third Sunday, my sister and I were responsible for preparing the meal and setting the Sunday table while everyone else went to church, and in this way, we learned very early to cook and handle food. Of course, bacon wasn’t just an everyday snack—it was also on the menu on Sundays and holidays, for example, as a side dish to roast beef in the form of bacon beans, which were very popular at our home. During the week, we often ate bacon dumplings or cabbage noodles with bacon.

Summer Duties & Father’s Love for Work

In summer, while the parents were in the barn, we children had to handle the phone: taking calls from customers who had ripe crops and needed one of our combine harvesters. We had to write down names and phone numbers and note the expected day of harvest readiness. If bad weather was forecasted, the phone rang incessantly because everyone wanted to get the grain in before it got wet. When Dad came from the barn and had eaten his scrambled eggs with bacon, he called everyone back and planned his appointments. On days when he knew he wouldn’t be home for lunch, there was a more substantial breakfast.

Father’s Dedication and Bacon Tradition

My father loved work, and there was always something to be done. For him, work was an essential part of life and a source of satisfaction, not merely a duty. I am very grateful that he was able to instil this attitude in me and pass on his love for our bacon tradition, just as I pass it on to my children.

Introduction

A new chapter has opened on Origins Global Meats, and it began not with a scientist but with a storyteller. Our Bacon Stories is a series introduced by Christa Berger, whose life, land, and lineage reveal a truth I never saw coming: Bacon is not just cured meat, it is cultural memory, family identity, and spiritual ritual. Her first article moved me deeply. I had tears in my eyes, not as a food scientist, but as a man witnessing something far greater than the product I thought I had mastered.

Opening My Eyes to Magic

Christa is Styrian by birth and spirit; sharp-witted, warm-hearted, and full of insight. Her background bridges medicine and anthropology. She trained in radiology and anatomy, which gave her an intuitive understanding of muscle, tissue, and blood, insights that became invaluable when we began working together on the science of meat curing. But more than that, she brought memory. She brought soul.

In 2024, Christa contacted me after reading my research on ancient salts. That message became the start of the most meaningful collaboration of my life. Since then, I’ve travelled to Austria several times. Together, we’ve traced the footsteps of ancient butchers and monks, knelt in Easter rituals, studied ancient salts, and rediscovered something I had lost in all my scientific digging: a sense of belonging.

Christa grew up in a Styrian world where bacon isn’t discussed; it’s understood! In her family, it is not a concept; it is the kitchen table. It’s the work of the hands. It’s church, and hunger, and generosity, and the silence that settles when something meaningful is placed on a plate.

She now runs Korrekturdienst, her language and editing company, one of the sharpest, clearest, most exacting firms I’ve ever encountered. But it isn’t the technical precision that makes her work magical. It’s her ability to hold meaning. She understands tone and hears subtext. She translates not just words, but worlds. What makes her work stand out is not just accuracy, but the unshakeable trust her clients place in her. They know that what they send her is safe. They know that what comes back will be cleaner, clearer, and completely context-aware. It will be right.

That’s because Christa works the way her ancestors cured bacon: patiently, carefully, and always with both eyes on meaning. Nothing vague. Nothing missed. Nothing less than exact.

She also hosts Der Steirische Brauch, a blog that brings to life the rhythms and rituals of her homeland—seasonal customs, food preparation, mountain traditions. It’s not just content; it’s connection.

The South African Who Thought He Knew Bacon

My own story of bacon began in my thirties. I was still in South Africa, still working in commercial chemicals, when I became fascinated with food chemistry. That curiosity became an obsession. I spent 15 years tracking the historical development of bacon—how curing works, why it works, and what the great scientists and artisans of the past discovered. It became the foundation of my book, Bacon & the Art of Living.

I thought I had covered everything: prehistoric methods, industrial breakthroughs, the modern nitrosamine crisis. In one of my latest pieces, The Crusade Against Nitrites: How Ideology, Fear, and Political Opportunism Hijacked the Science of Meat Safety, I push back against misinformation that continues to plague our industry.

But all my scientific knowledge lacked one thing: context. I knew bacon. But I didn’t feel it. Not until I stood beside Christa in Graz.

Austria: Where Bacon Has a Soul

Bacon in Austria is not a side note. It’s the language of the land. You walk into any SPAR store in Styria and find yourself overwhelmed, not by choices, but by pride. Cured meat is in the blood here. It’s not sold. It’s offered.

This Easter, I stood with Christa at Mariatrost Basilica for the meat blessing. You can read about it—(Historical Origins, Symbolism, and Easter Traditions of Cured Meats), but words are not enough. You have to be there. You have to watch the people carry their meats to be blessed, not just for flavour, but for life. Because bacon here is tied to survival, to winter, to the sacredness of nourishment.

And there’s something else. If you overlay Austria’s meat consumption with colorectal cancer rates, the myth falls apart. There is no link. Perhaps the problem isn’t bacon, but the way we’ve removed culture from food.

What Christa Gave Me and Gave Bacon

Since we began working together, Christa has become more than a collaborator. She’s brought something into Origins Global Meats that I couldn’t have created alone. A kind of rootedness. A kind of clarity. Her story of bacon, of her father, her siblings, her mother; it opened a door in me. It reminded me that food is not just science. It is family. It is history. It is place.

What she brought wasn’t technique. It was truth. She didn’t try to be special. She was simply true to herself, her upbringing, her heritage. And that same truth runs through everything she does, whether she’s editing a doctoral thesis, writing about sacred rituals, or building a new business with me.

My connection to bacon has always been strong. But since last year, it has become something I didn’t even know I was missing.

A homecoming.

Introduction

Meat bones are not a product in Nigeria. Bones are discarded. I first had to conceptualise the output of beef bones with tendons and other items from the deboning hall to the production freezer where it will be stored for production, for a maximum time of 7 days from input into the freezer. The packaging of the bones had to be considered: Optimal Storage Practices for Beef Bones: Ensuring Quality for Future Processing. I had to consider how the freezers will be cleaned: Comprehensive Guidelines for Cleaning and Maintenance of -18°C Freezers with Temperature Management.

The comprehensive strategy for handling these freezers has been discussed in Optimal Strategy for Freezer Management and Other Areas Often Neglected in Meat Plants

Recipe for Beef Bone Broth

Now it’s time to look at how we are going to process the bones and what we are going to do with the resultant broth. First, we need a recipe for the broth.

Ingredients:

• 100 kg beef bones (mixture of marrow bones, knuckle bones, and meaty bones)
• 40 liters water
• 10 kg onions, roughly chopped
• 5 kg carrots, roughly chopped
• 5 kg celery stalks, roughly chopped
• 1 kg leeks, roughly chopped
• 1 kg garlic cloves, smashed
• 20 bay leaves
• 1 bunch fresh thyme
• 1 bunch fresh parsley
• 500 g whole black peppercorns
• Salt, to taste

Instructions

1. Preheat the oven to 400°F (200°C). Place the beef bones on large baking sheets and roast them in the oven for about 2 hours, or until they are deeply browned and caramelized.
2. Transfer the roasted bones to large stockpots or kettles. Add the water, onions, carrots, celery, leeks, garlic, bay leaves, thyme, parsley, and black peppercorns.
3. Bring the mixture to a boil over high heat, then reduce the heat to low and simmer, partially covered, for at least 24 hours, preferably 48 hours. Skim off any foam or impurities that rise to the surface.
4. After simmering, strain the broth through fine-mesh sieves or cheesecloth into other large pots or containers. Discard the solids.
5. Let the broth cool to room temperature, then portion it into clean 20-litre drums for long-term storage. Seal the drums tightly and store them in a cool, dark place or refrigerate them if possible.

Usage of Beef Bone Broth

Once the broth has been created, now we must consider where we will use it.

1. Sausages: Incorporate the beef bone broth into sausage formulations to enhance flavour and moisture retention. For example, for every 10 kg of ground meat, use 1 kg of beef bone broth in the sausage mixture.
2. Fresh Meat Products: Use beef bone broth as a liquid component in fresh meat products such as meatballs, meatloaf, and burgers to improve juiciness and flavour. Use approximately 10% of the total meat weight as beef bone broth in these formulations.
3. Bacon and Hams: Utilize the beef bone broth as a brine solution for curing bacon and hams to add richness and depth of flavour. Replace water with beef bone broth in the brine solution, following standard curing ratios and procedures.
4. Small Goods and Delicatessen: Use the beef bone broth as a base for soups, sauces, and gravies in the production of small goods such as pâtés, terrines, and sausages. Adjust the amount of broth according to desired flavour intensity and consistency in each recipe.

These applications of beef bone broth will enhance the flavour, moisture, and overall quality of your factory’s products, providing added value and customer satisfaction.

Storage of Broth

The optimal way to store beef bone broth in a freezer is to follow these steps:

1. Portioning: Divide the broth into manageable portions that are suitable for your production needs. For example, pour the broth into smaller containers or bags, ensuring that each portion is properly sealed to prevent freezer burn and contamination.
2. Cooling: Allow the broth to cool to room temperature before transferring it to the freezer. Rapid cooling can be achieved by placing the containers in an ice bath or using a blast chiller.
3. Freezing: Place the sealed containers of broth in the freezer, ensuring they are arranged in a single layer for even freezing. Leave some space between containers to allow for expansion during freezing.
4. Labelling: Clearly label each container with the date of production and contents to ensure proper inventory management and rotation.
5. Storage: Store the broth in the coldest part of the freezer, maintaining a consistent temperature of 0°F (-18°C) or below.

Thawing Procedure

When thawing beef bone broth for use in production, follow these steps:

1. Refrigerator Thawing: The safest method is to transfer the frozen broth from the freezer to the refrigerator and allow it to thaw overnight. This gradual thawing process maintains the quality and integrity of the broth.
2. Cold Water Thawing: If time is limited, submerge the sealed container of frozen broth in cold water. Change the water every 30 minutes to ensure it remains cold. This method will thaw the broth more quickly than refrigerator thawing but requires more attention to prevent bacterial growth.
3. Microwave Thawing: Thawing broth in the microwave is not recommended as it can result in uneven heating and potential food safety risks.
4. Thawing in Production: If immediate use of the broth is required, it can be thawed directly in the production process. Ensure that the broth is heated to a safe temperature (above 165°F or 74°C) to kill any potential bacteria before use.

Storage Duration

Beef bone broth can be stored in the freezer for up to 6 months without significant loss of quality. However, for optimal flavour and freshness, it is best to use the broth within 3 months of freezing. Proper storage and handling practices, such as maintaining a consistent freezer temperature and minimizing exposure to air, will help prolong the shelf life of the broth.

Storage Containers

Storing beef bone broth in sealed drums is a practical and efficient method for long-term storage. Here’s how you can do it:

1. Portioning: Divide the beef bone broth into manageable portions suitable for your production needs. Pour the broth into food-grade plastic bags or containers that are specifically designed for freezer use.
2. Sealing: Ensure that each bag or container is properly sealed to prevent leakage and contamination. For bags, use a heat sealer or twist tie to securely close the opening. For containers, use tight-fitting lids that form a complete seal.
3. Arranging in Drums: Once the broth is portioned and sealed, place the bags or containers inside clean and sanitized 20-litre drums. Arrange them in layers, ensuring that there is sufficient space between each container to allow for proper airflow and freezing.
4. Labelling: Clearly label each drum with the date of production, contents, and any other relevant information such as batch number or expiration date. This will facilitate proper inventory management and rotation.
5. Sealing Drums: Seal the drums tightly to prevent air and moisture from entering. Use sealing tape or locking rings to secure the lids in place and ensure a tight seal.
6. Freezing: Place the sealed drums of beef bone broth in the coldest part of the freezer, maintaining a consistent temperature of 0°F (-18°C) or below.

By storing beef bone broth in sealed drums, you can ensure that it remains fresh and flavorful for an extended period, ready to be used in various meat products whenever needed.

Conclusion

In summary, the discussion surrounding beef bone broth has shed light on its importance in the meat industry, particularly in the production of sausages, fresh meat, bacon, hams, and other small goods. By utilizing a carefully crafted recipe and production process, beef bone broth serves as a versatile ingredient that enhances flavour, moisture retention, and overall quality in various meat products.

The optimal recipe for beef bone broth involves simmering a mixture of beef bones, vegetables, and aromatics for an extended period to extract maximum flavour and nutrients. This rich and flavorful broth can then be stored for long-term use in sealed drums, ensuring its freshness and integrity.

Furthermore, the versatility of beef bone broth extends to its usage in a wide range of meat products, including sausages, fresh meat, bacon, hams, and small goods. Whether used as a liquid component in formulations or as a base for soups, sauces, and gravies, the beef bone broth adds depth of flavour and nutritional value to the final products.

In conclusion, the production, use, and storage of beef bone broth are essential aspects of meat processing operations, contributing to the overall quality and satisfaction of consumers. By following proper recipes, production techniques, and storage practices, meat manufacturers can harness the full potential of beef bone broth to elevate their products and meet the ever-evolving demands of the market.

Introduction

How does ascorbate or Vitamin C prevent nitrite from reacting with secondary amines to form nitrosamines which can be cancer-causing? The meat curing industry uses ascorbate wherever nitrite is used, thus mimicking conditions in leafy green vegetables.

More than this, the interplay between dietary components and physiological mechanisms has profound health implications, exemplified by the nitrate-nitrite-nitric oxide (NO) pathway. This pathway highlights the significance of diet in regulating bodily functions and showcases the potential of dietary elements to influence the synthesis of essential signalling molecules like nitric oxide. Ascorbate, or vitamin C, plays a pivotal role in this context, acting as a key agent in the reduction of nitrite to nitric oxide. This article integrates insights from Earthworm Express to further explore the biochemical reactions facilitated by ascorbate and the broader implications of the nitrate-nitrite-NO pathway for health.

Ascorbate’s Role in Nitrite Reduction

Ascorbate acts as a powerful reducing agent, catalyzing the conversion of nitrite (NO2-) into nitric oxide (NO). This reaction, essential for numerous physiological functions, involves the donation of electrons by ascorbate to nitrite, yielding NO, dehydroascorbate, and water.

The reaction between nitrite (NO₂⁻) and ascorbate (vitamin C, C₆H₇O₆⁻) can be represented as:

NO₂⁻+C₆H₇O₆−→NO+C₆H₆O₆+H₂ONO₂−​+C_6​H₇​O₆−​→NO+C_6​H₆​O₆​+H₂​O

In this reaction, nitrite (NO₂⁻) reacts with ascorbate to produce nitric oxide (NO), dehydroascorbic acid (C₆H₆O₆), and water (H₂O). This process is significant in the context of meat curing, where nitrite serves as a preservative and colouring agent and can react with ascorbate added to the meat product to enhance colour formation and stability, as well as potentially contribute to the formation of nitric oxide, which has various biological effects.

Regarding the form in which nitrite exists in the stomach, it can be present as both NO₂⁻ and HNO₂ (nitrous acid), depending on the pH of the environment. In the acidic conditions of the stomach (pH ≈ 2), nitrite can be protonated to form nitrous acid (HNO₂).

In the realm of food science, particularly in meat curing processes, the inclusion of ascorbate accelerates this conversion, enhancing both the preservation efficacy colour and development of meat products. Earthworm Express provides practical insights into this application, emphasizing the importance of ascorbate in enhancing the quality and safety of cured meats.

The Nitrate-Nitrite-Nitric Oxide Pathway Explained

The pathway is a crucial biological process through which dietary or endogenously produced nitrate and nitrite are converted into nitric oxide. Serving as an auxiliary to the classical L-arginine-NO synthase pathway, it offers a vital mechanism for NO synthesis, especially under oxygen-limited conditions.

1. Dietary Intake and Conversion – The process begins with the intake of nitrate-rich foods, leading to the conversion of nitrate to nitrite by oral bacteria, a critical step for NO synthesis.

2. Formation of Nitric Oxide – Nitrite is then reduced to NO either enzymatically in tissues or non-enzymatically in acidic conditions, with ascorbate playing a significant role in facilitating this reduction.

Physiological Value of Nitrite

Contrary to its historical perception as an inert by-product or health hazard, nitrite is now recognized for its crucial physiological roles:

– Vascular Health: As a regulator of vascular tone and blood pressure, nitrite-derived NO plays a key role in cardiovascular health.

– Cytoprotection: Nitrite offers protection against ischemia-reperfusion injury by acting as a NO reservoir.

– Oxygen Delivery: It ensures efficient oxygen utilization in hypoxic tissues through vasodilation.

– Immune Function: The antimicrobial properties of NO, generated from nitrite, are essential for immune response.

Conclusion and References

The ascorbate-mediated reduction of nitrite to nitric oxide within the nitrate-nitrite-NO pathway demonstrates the complex interactions between diet, biochemistry, and physiology. This pathway not only underscores the biological importance of nitrite but also highlights the therapeutic potential of dietary nitrate and nitrite in cardiovascular and metabolic health management. The insights from Earthworm Express enrich our understanding of these processes, particularly in the context of food science and meat curing.
