Process of extracting sturgeon oil

Abstract

The process of extracting sturgeon oil includes the following steps: grinding sturgeon maw and internal organs, adding 3-4 times of water and small amount of antioxidant, enzymolysis, stilling to delaminate, separating to obtain coarse sturgeon oil, and deacidifying, deodorizing and defatting coarse sturgeon oil to obtain refined sturgeon oil. The process has high sturgeon oil extracting rate, low peroxide number of the sturgeon oil product, high product quality, capacity of obtaining fish protein enzymolyzing matter also with the enzymolysis liquid, and other advantages.

Description

technical field

[0001] The invention relates to a new method for extracting sturgeon oil, in particular to the application of enzymatic hydrolysis technology in the extraction of sturgeon oil. Background technique

[0002] Sturgeon, also known as Sturgeon, is the oldest and most primitive cartilaginous fish species on earth like sharks. It is the largest and longest-lived fish among freshwater fishes, and has high economic and scientific value. With the success and popularization of sturgeon artificial breeding and breeding technology, my country's sturgeon farming industry has achieved remarkable results. The breeding area and production of sturgeon are increasing year by year. The comprehensive utilization of sturgeon has become a hot issue that researchers have paid attention to in recent years. .

[0003] Sturgeon has white and tender meat, no earthy smell of freshwater fish, and delicious taste. It has been regarded as a treasure in water since ancient times and is favo...
