Perilla protein is used in food and nutraceutical industries due to its high nutritional value and functional properties. It serves as a plant-based protein source in protein bars, dietary supplements, and fortified foods, especially in vegetarian and vegan products. Its balanced amino acid profile supports muscle development and overall health. The protein also exhibits emulsifying and foaming properties, making it useful in processed foods like plant-based meat and dairy alternatives. Additionally, perilla protein has been studied for bioactive peptides that may offer anti-inflammatory and antioxidant benefits, contributing to functional food development aimed at improving health and preventing chronic diseases.
