文摘

Proteins are renewable resources rich in animals and plants and can be extracted from the agricultural and breeding industry byproducts and wastes. Collagen, keratin, zein and soy proteins are found in these byproducts and are extensively studied for protein-based hydrogels, which are especially attractive as a promising biomaterial due to their excellent biocompatibility, biodegradability, nontoxicity and low immune response. In recent years, hydrogels have been playing an increasingly important role in tissue engineering, drug delivery, nutrient encapsulation, controlled release of pesticides and other fields. The diversity of the amino acid composition of proteins leads to significant differences in their processing strategies, and the properties of the resultant hydrogels. This review covers the extraction methods for collagen, keratin, zein and soy proteins from various industrial byproducts, the synthesis of hydrogels from these protein sources, as well as their potential applications.
