Method for separating and purifying abalone proteins

Abstract

The invention relates to a method for separating and purifying abalone proteins, which comprises the following steps of: 1, pulping washed abalone visceral organs, processing the obtained pulp in a high-voltage pulse electric field, centrifuging and removing supernatant fluid containing polysaccharide and fat to obtain abalone protein precipitates; and 2, washing proteins separated from the abalone visceral organs in edible alcohol, centrifuging, taking out the precipitates and eluting the precipitates repeatedly. Due to the adoption of the combination of a PEF (high pressure polyethylene) cell membrane electroporation technology and an ethanol decoloration technology, the yield and the purity of the proteins can be effectively improved and the obtained proteins have invariance property and high quality. The proteins can be further hydrolyzed to prepare condiments or functional health care products.

Description

technical field [0001] The invention relates to the field of processing leftovers from aquatic product processing. Background technique [0002] Abalone is a precious marine product with rich nutritional value, but it is difficult to solve the problem of fishy smell in the production of abalone protein, and it often becomes waste, which cannot be used and causes great environmental pollution. At present, there is no report on the separation and purification of abalone protein at home and abroad. Contents of the invention The invention provides a method for separating and purifying abalone protein. The method aims at increasing the added value of the abalone; providing good raw materials for preparing condiments and functional health products from marine aquatic products; and reducing environmental pollution and energy consumption during the deep processing of the abalone. The technical scheme of the present invention is: it comprises the following steps A) Wash the...
