Proteins extracted from various sources have become a necessity in the food and pharmaceutical industry. There are various sources from which proteins are extracted- plants, animals, eggs, and microbes. The animal protein ingredients include bone meal, blood meal, fish meal, feather meal, etc. They are usually derived from animal by-products. The products like hydrolase collagen and fish oil are very much dependent on the animal protein ingredients market. The animals are a much richer source of proteins and hence, the animal protein ingredients market lever an advantage and growth over its parallel industry, that is, plant-based proteins.
