Channel catfish farming is very important aquaculture industry in the southern states of the USA. However, huge amounts of by-products are generated from catfish fillet-processing. The by-products (mostly heads and bone frames) are excellent sources of proteins. Currently, catfish by-product has little value, and is regarded as a ‘waste’, which if not utilized properly could cause serious environmental pollution. Therefore, to find a way to utilize those by-products is critical for the economy of aquaculture.

蛋白质提取 pH 值和交联影响由鲶鱼副产品制成的蛋白质凝胶的理化和质地特性

鲶鱼养殖是美国南部各州非常重要的水产养殖业。然而，鲶鱼鱼片加工会产生大量副产品。副产品（主要是头部和骨骼框架）是极好的蛋白质来源。目前，鲶鱼副产品价值不大，被视为“废物”，如果利用不当，可能会造成严重的环境污染。因此，找到一种利用这些副产品的方法对水产养殖经济至关重要。
