Abstract

The invention discloses a synchronous enrichment method of lipide and protein in pandalus borealis processing by-products. The synchronous enrichment method comprises the following steps of (1) pretreating raw materials; (2) performing extraction: adding an oil phase to an enzymolysis system obtained in the step (1), then inputting air currents to the system through a microbubble generator, and then collecting crude extraction solutions in a manner of filtering or centrifuging manner; (3) constructing a multiphase separation system; (4) treating a lipide phase: collecting an upper phase solution in a layering system obtained in the step (3), then performing decompressed concentration, and recovering a solvent so as to obtain a lipide extract; (5) treating protein: collecting interlayer substances obtained in the step (3), and performing drying so as to obtain a protein extract; and (7) performing an aqueous phase: collecting a lower-layer salt-containing aqueous phase solution obtainedin the step (3), and performing recycling. A new thinking is provided for further developing and increasing the added value of the pandalus borealis, and a new value growth point is provided for theindustry chain.

Description

technical field [0001] The invention belongs to the technical field of lipid and protein extraction, and in particular relates to a method for synchronously enriching lipid and protein in arctic sweet shrimp processing by-products. Background technique [0002] Arctic sweet shrimp is mainly produced in the Arctic Ocean and the North Atlantic Ocean. It is a natural wild shrimp. At present, the annual harvest of Arctic sweet shrimp is about 290,000 tons. The annual processing volume of Arctic sweet shrimp in my country is about 4,000 tons, which is a huge amount. With the increase of fishing volume and processing volume, the amount of processed by-product resources is increasing year by year, which causes waste of resources and aggravates environmental pollution. Therefore, it is urgent to develop an efficient and feasible way of comprehensive utilization of arctic sweet shrimp by-product resources. [0003] Preliminary experimental studies have shown that Arctic sweet shrimp...
