What are bioactive proteins?

Lactoferrin, lactoperoxidase, lactenin, and TGF Beta: these are some of the bioactive proteins derived from milk. Read on for an overview of the features and benefits of these ingredients that help the body function properly.

Proteins, macronutrients that are essential to our diet

First of all, what are proteins? These biological molecules composed of amino acids play three major roles in our diet.

• Nutritional role

When proteins are digested, they provide essential nutrients for the body’s development and functions. Some amino acids cannot be synthesized by the body and must therefore be consumed through the diet.

• Texturizing role

This includes ingredients such as emulsifiers, thickeners, etc. Proteins provide texturizing and taste-enhancing properties in foods and formulations. They have particularly useful functional properties and are considered as ingredients in their own right in recipes. In addition to this, they add nutritional value to the finished product, which is beneficial for consumers.

• Bioactive role

Beyond their essential nutrient function, some proteins also play an active role in the proper functioning of our bodies. They contribute to its development, protection, and reduced risk of health problems.

Bioactive proteins: promoting health at the biological level

Bioactive proteins are beneficial to our bodies, both physiologically and metabolically. They can have an antioxidant and antimicrobial effect and aid with healing. Lactoferrin and lactoperoxidase in particular play an important role in the immune defense system. They boost the body’s natural protection against pathogens.

Bioactive proteins are naturally present in biological fluids including saliva and tears. Many can be found in mammals’ milk, one of the functions of which is to strengthen the immune system of newborns. Armor Protéines uses its 30-year experience in these bioactive proteins to make them available to user industries.

The many health benefits of bioactive proteins have led the nutrition, hygiene, beauty, and agri-food industries to use them increasingly. Nowadays, they can be found in the diets of young children, the elderly, and athletes; as well as in cosmetic products, dietary products, and dietary supplements.
