Description

Technical Field

[0001] The utility model relates to the technical field of enzymolysis tanks, in particular to a nitrogen-filled enzymolysis tank used for seaweed extracts. Background Art

[0002] Brown algae are rich in active substances. The main agricultural application is to use its water-soluble extracts, which mainly contain seaweed polysaccharides, alginic acid, and mannitol. The content of alginic acid is an important indicator for evaluating the quality of seaweed fertilizer. Seaweed extracts have good compounding properties;

[0003] Biological enzymatic hydrolysis reactions are highly specific. Selecting the corresponding protease can quickly degrade large molecular proteins into small molecular peptides and free amino acids. At present, the technology of preparing small molecular peptides by enzymatic hydrolysis has been successfully applied to the animal and plant protein industry, but in the field of aquatic product processing, there are still some deficiencies in the process of preparing various aquatic peptides by enzymatic hydrolysis, which is related to the characteristics of aquatic products. In addition to rich protein, seaweed extracts often contain more polyunsaturated fatty acids, such as EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid). These unsaturated fatty acids are beneficial to human health, but because they contain multiple unsaturated double bonds, they are very easy to be oxidized, producing peroxides and free radicals, which are harmful to human health:

[0004] Traditional enzymatic hydrolysis of aquatic products is generally carried out in an enzymatic hydrolysis tank. To facilitate the entry and exit of materials in the enzymatic hydrolysis tank, a breathing hole is designed on the top of the tank. To ensure the pressure balance inside and outside the tank, the breathing hole is directly connected to the outside atmosphere, so that the enzymatic hydrolysis raw materials and the enzymatic hydrolysis liquid can have sufficient contact conditions with the oxygen in the air. The enzymatic hydrolysis conditions of protein are generally 50-60℃, and the enzymatic hydrolysis time is 4-6 hours. This high temperature and long enzymatic hydrolysis condition can easily cause unsaturated fatty acids such as DHA and EPA in fish paste to undergo oxidation reaction with oxygen, resulting in the production of peroxides from seaweed extracts in the enzymatic hydrolysis liquid, an increase in acid value, and a decrease in iodine value. Moreover, as the oxidation process occurs, the unique fishy smell of aquatic products will continue to increase. In addition, the uniformity of the enzymatic hydrolysis tank during stirring is poor, which affects the yield. Summary of the invention
