Problems solved by technology

At present, the methods for preparing oyster peptides from oyster shells mainly include acid hydrolysis and enzymatic hydrolysis. The acid hydrolysis reaction is violent, the reaction process and the final product are difficult to control, and will cause the destruction of a large number of amino acids. Direct enzymatic hydrolysis with oyster powder is difficult. Long time, difficult to filter, low peptide yield

Embodiment Construction

[0017] Accompanying drawing is a kind of specific embodiment of the present invention. Such as figure 1 As shown, this embodiment comprises the following steps: (1) drop into oyster powder 1kg, add deionized water 15600-15700ml after the feed intake is finished, shear by the emulsifying shear at the bottom of the tank, and return to the tank; (2) add 30-36ml 30% liquid caustic soda, adjust the pH of the feed solution to 7.0-7.5, heat up to 48-52°C, add 10-20g of neutral protease, start enzymolysis, and the enzymolysis time is 6 hours; (3) heat up to 80°C 10min to inactivate enzymes: (4) After centrifugation, filter with ceramic membrane, vacuum concentration concentration is 20%, after sterilization, feed liquid is spray-dried and passed through 60 mesh sieve, measured, packed in compound bags, inspected, and put into storage after passing the test.

[0018] The production method requires raw material requirements: oyster powder: moisture ≤ 7.0%, protein ≥ 42%, ash ≤ 3.30%, f...

Abstract

The invention discloses an industrial production method for preparing oyster bioactive peptides from oyster powder through enzymatic method, which is characterized in that: the special of the production method lies in comprising the following steps: (1) inputting the oyster powder of 1kg, adding deionized water, carrying out shear through the emulsion shearing machine on the bottom of a tank after finishing feeding and reflowing into the tank; (2) regulating the PH of the feed liquid to 7.0 to 7.5, warming up to 48 to 52 DEG C, adding neutral protease of 10 to 20g and beginning enzymolysis for 6 hours; (3) warming up to 80 DEG C and carrying out killing enzyme for 10 minutes; (4) filtering with ceramic membrane, carrying out spray drying and passing through 60 mesh sieve for the feed liquid when the concentration of vacuum concentration is 20% and packaging with compound bag. The industrial production method has the advantages that: the technology is simple; the generating period is short; the produced oyster bioactive peptides are white, not fishy smell and good taste; and the molecular weight of the contained mixing peptide is small.

Description

(1) Technical field [0001] The invention relates to a production method of oyster peptide, in particular to an industrial production method for enzymatically preparing oyster peptide from oyster powder. (2) Background technology [0002] Oyster powder contains a certain amount of protein, but it is difficult to be absorbed by organisms. Peptides are absorbed by organisms faster than the same amount of free amino acids, and far faster than the same amount of protein. Making oyster peptides from oyster powder can be better digested and absorbed. At present, the methods for preparing oyster peptides from oyster shells mainly include acid hydrolysis and enzymatic hydrolysis. The acid hydrolysis reacts violently, the reaction process and the final product are difficult to control, and will cause the destruction of a large amount of amino acids. Direct enzymatic hydrolysis with oyster powder is difficult. Long time, difficult to filter, low peptide yield. (3) Contents of the in...
