Embodiment Construction
[0013] In the first aspect, the present invention provides a method for comprehensively utilizing shrimp processing by-products.
[0014] A method for comprehensively utilizing by-products of shrimp processing comprises the following steps: pretreatment, extraction of shrimp protein peptides, extraction of shrimp oil, extraction of chitin and preparation of organic acid calcium.
[0015] The pretreatment includes washing and crushing.
[0016] The shrimp protein peptide extraction includes: mixing the pretreated shrimp processing by-products with water, adjusting the pH, optionally adding enzymes, reacting at 30-60° C. for 4-8 hours to inactivate the enzymes, more preferably at 40 After reacting at -50°C for 4-8 hours, inactivate the enzyme, cool to room temperature, and centrifuge to obtain the first supernatant and the first precipitate. The first supernatant is filtered to obtain the first filtrate. The first filtrate is concentrated and / or drying to obtain the shrimp pro...
