| 摘要 |
The present invention is directed to a process for the production of wet solutions of peptides concentrated to 50% or dry peptides, for human and animal consumption, using as raw material secondary products generated in the production of protein food for human consumption, which is started with a low temperature fat extraction previous to the enzymatic action, which is distorted by the presence of fat and is the enzymatic hydrolysis is combined with acid hydrolysis, increasing the protein yield to nearly 100%, eliminating organic liquid industrial waste (LIW) from industrialization, starting from products and residues of animal protein origin, fish and aquaculture. This process comprises the steps of: (a) milling raw material and pump to heat exchangers; (b) heating raw material; (c) centrifuge raw material to form a product with a lower fat content; (d) pump the product with lower fat content to digestion tanks; (e) modify pH of the product by adding acids or bases: (f) heat the digestion tanks and adding a mixture of proteolytic enzymes; (g) pump the product once the enzymatic process is complete to a heat exchanger to increase the product temperature; (h) centrifuge the product to extract the remaining oil and separate the non-hydrolyzed solids and the liquid with soluble solids and peptides.
