Problems solved by technology

[0006] Both of the above two methods use the second method to prepare fish oil. The purity of the obtained fish oil is higher than that of the first method, but the extraction rate of fish oil is not ideal, and subsequent decolorization, deodorization, and impurity removal are required Processing, the process is more cumbersome, affecting production efficiency

Abstract

The invention relates to the field of the processing of fish products and discloses a fine processing method of fish oil. The fine processing method of fish oil comprises the following steps: a, washing fish guts, removing giblets, pounding the fish guts to prepare a blank material; b, adding the blank material into an enzymolysis solution containing an immobilized magnetic composite enzyme for carrying out enzymolysis, and recycling the immobilized magnetic composite enzyme by using a magnet after carrying out enzymolysis; c, filtering the enzymolysis solution to remove residues, then standing and layering, and separating to obtain upper fish oil and lower oil-water mixed solution; d, transferring the oil-water mixed solution to a foam separating column, aerating the bottom of the foam separating column, generating a foam layer on the upper layer of the oil-water mixed solution, and separating the foam layer from the liquid in time; e, carrying out centrifugal separation on the oil-water mixed solution to obtain upper fish oil; f, mixing the upper fish oil obtained in step c with the upper fish oil obtained in step e to prepare the fish oil. The processing method of the fish oil is simple in the process and high in the extraction efficiency and the extraction rate; the processed fish oil is high in purity, free of fishy smell and pure in color.

Description

technical field [0001] The invention relates to the field of fish product processing, in particular to a delicate processing method of fish oil. Background technique [0002] Fish oil is one of the important components of fish. Fish oil is rich in EPA and DHA and other unsaturated fatty acids. It has the functions of lowering blood pressure, eliminating fatigue, preventing cerebral thrombosis, and improving memory. Therefore, fish oil is widely used in food, medical, feed industry and other fields. [0003] At present, the preparation method of fish oil is mainly as follows: 1. Put the raw materials into boiling water for boiling, and then extract the fish oil floating on the upper layer by centrifugation or by organic solvent. The fish oil extracted by the above method is not high in purity, and impurities such as water, protein, and colloidal substances are easily brought in, and further refining and purification are required, and the operation is extremely complicated. ...
