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...

Description

technical field [0001] The invention relates to the technical field of comprehensive utilization of aquatic product waste, in particular to a method for comprehensive utilization of shrimp processing by-products. Background technique [0002] Shrimp is an important source of human protein and one of the bulk aquatic products in my country. At present, more than 1 million tons of shrimp products are processed annually in my country, and a large number of by-products such as shrimp heads and shells will be produced during the shrimp processing process, and these by-products account for 30% to 40% of the shrimp mass. At present, enterprises mainly deal with by-products such as shrimp heads and shells by selling them at low prices or processing fishmeal and feed, and the added value of the products is low. During the peak season of shrimp processing, shrimp heads and shells are even treated as waste, which has a serious impact on the ecological environment. [0003] In the pri...
