Abstract

The invention discloses a one-step method for efficiently preparing cod liver protein and cod liver oil. The specific operation steps are as follows: thaw raw and frozen cod liver and tie it into thin slices; heat to denature cod liver slice protein; add surfactant to form supercritical The micellar system is then extracted; the clarification of the extracted product is facilitated by adding a flocculant and the back-extraction of the substance in the supercritical micelles by low-carbon alcohol; the extractant is removed after the extraction is completed; the cod liver protein powder and the oil-water mixed extraction product are collected separately ; High-speed centrifugal oil-water mixed extraction product separation obtained cod liver oil. The method has the advantages of simple operation, low extraction pressure and low solvent residue. The subcritical extraction method can be completed under low temperature and sealed conditions, which can keep heat-sensitive components such as vitamin A, vitamin D, EPA and DHA in the cod liver from being oxidized and thermally decomposed to the greatest extent, and can directly extract high-moisture cod liver and simultaneously Cod liver oil and cod liver protein powder are prepared, which greatly improves production efficiency and reduces production cost.

Description

technical field [0001] The invention relates to the technical field of marine aquatic product processing, in particular to a method for obtaining cod liver protein powder and cod liver oil from cod liver with high water content by using a subcritical extraction technique in one step. Background technique [0002] Cod liver is rich in protein, which is a good source of animal protein, and contains a large amount of unsaturated fatty acids and superoxide dismutase, which has a wide range of application values. Superoxide dismutase is a metalloenzyme widely present in animals, plants and microorganisms, and it is the first line of defense against free radicals in the body. Superoxide dismutase can promote the decomposition of superoxide free radicals, and has an obvious anti-lipid peroxidation effect, thereby protecting cells and tissues from damage and eliminating its damage to the human body. [0003] The traditional preparation method of cod liver powder is through enzymati...
