From Farm to Fork: The Science Behind Tastier, Safer, and Smarter Animal Foods
Animal resource science transforms how we produce, process, and enjoy foods like meat, milk, and eggs, making them more nutritious, sustainable, and safe through cutting-edge technology.
When you savor a juicy burger, slice into prosciutto, or enjoy a glass of milk, you're experiencing the final result of a vast, scientific field known as the food science of animal resources. This discipline goes far beyond traditional farming, incorporating principles of biotechnology, nutrition, genetics, and engineering to improve the quality and safety of the foods we get from animals. From tackling global food challenges to developing personalized nutrition for an aging population, scientists in this field are redefining our relationship with animal products. This article explores the exciting innovations—from using fruit powders to enhance the nutrition of sausages to deploying cold plasma to combat pathogens—that are shaping the future of our food.
What is Food Science of Animal Resources?
This field is a specialized branch of food science that focuses exclusively on foods derived from animals. Its scope is broad, encompassing the study of meat, dairy, eggs, and even emerging sources like edible insects 1 6 . Researchers strive to understand every aspect of these products, from the biological processes within the living animal to the biochemical changes that occur during cooking on your stove.
Key Goals of Animal Resource Science:
Enhance Nutritional Value
Optimizing the nutrient profile of animal foods to support human health.
Ensure Safety

Creating efficient systems and exploring alternative protein sources.
Recent publications in journals like the Korean Journal for Food Science of Animal Resources highlight groundbreaking work, including using AI to predict meat quality, developing cultured meat with scaffold biomaterials, and harnessing precision fermentation to create dairy alternatives 1 . These innovations demonstrate a field that is rapidly evolving to meet the demands of the 21st century.
Biotechnology
Using genetic engineering and microbial processes to enhance food properties and create alternatives.
Nutrition Science
Optimizing the nutritional content of animal foods for different consumer needs and life stages.
Food Engineering
Developing new processing techniques to improve safety, quality, and sustainability.
A Closer Look: Enhancing Food for Healthy Aging
To understand how animal food scientists work, let's examine a specific 2025 study that aimed to improve the quality of goat meat-fermented sausages for elderly consumers 1 . As people age, they often face challenges like decreased appetite, difficulty chewing and swallowing, and changing nutritional needs. This research sought to create a sausage that was both nutritious and easier to consume.
The Experiment: Using Fruit Powders to Improve Goat Meat Sausages
The methodology was designed to test whether natural fruit additives could positively alter the sausage's properties.
Sausage Preparation
Researchers produced multiple batches of fermented goat meat sausage. A control batch contained no fruit powder, while other batches were supplemented with set percentages of either pineapple powder or fig powder.
Additive Incorporation
The pineapple and fig powders were mixed uniformly into the sausage emulsion before the fermentation and drying processes.
Analysis
After production, the different sausage batches were analyzed and compared for texture, physicochemical properties, and nutritional value.

Results and Analysis: A Softer, More Nutrient-Dense Sausage
The study yielded clear, quantifiable results demonstrating the benefits of the fruit powder additives.
| Texture Profile Analysis of Goat Meat Sausages | |||
|---|---|---|---|
| Sausage Type | Hardness (N) | Chewiness (mJ) | Springiness (Ratio) |
| Control (No Additives) | 45.2 | 18.5 | 0.78 |
| With Pineapple Powder | 28.7 | 11.2 | 0.81 |
| With Fig Powder | 31.5 | 12.8 | 0.80 |
This data shows that adding fruit powders significantly reduced the hardness and chewiness of the sausages, making them easier to chew for the elderly, while maintaining good springiness.
| Key Nutritional Enhancements from Fruit Powders | ||
|---|---|---|
| Nutrient / Component | Pineapple Powder Contribution | Fig Powder Contribution |
| Dietary Fiber | Moderate increase | Significant increase |
| Potassium | Moderate | High |
| Natural Enzymes (Bromelain) | High (aids in tenderness) | Not Applicable |
The addition of fruit powders boosted the nutritional content of the sausages, particularly increasing dietary fiber and essential minerals, which are often deficient in the diets of the elderly.
The primary finding was that both fruit powders significantly reduced the hardness and chewiness of the sausages, directly addressing the challenge of difficulty chewing. The researchers attributed this textural improvement to the enzymatic activity from the fruits, which helps break down proteins and soften the meat structure. Furthermore, the fruit powders enhanced the nutritional profile by adding dietary fiber, essential minerals, and natural antioxidants. The study concluded that this approach successfully created a tailored meat product that aligns with the specific physiological needs of older adults, without compromising on safety or sensory appeal.
