Problems solved by technology

At present, the methods for preparing wheat peptides from gluten 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 amount of amino acids. Direct enzymatic hydrolysis with gluten powder is very 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 Shown, the production process of this embodiment is as follows: (1) drop into gluten powder 1kg, add deionized water 11500-11600ml, after feeding intake finishes, shear by the emulsification shearing machine at the bottom of the tank, and return to flow into tank; 2) Heat up to 50-55°C, add lye to adjust the pH of the feed solution to 7.5-8.0, add 1-2g of compound protease (special enzyme for wheat hydrolysis), and start enzymolysis, and the enzymolysis time is 8 hours; (3) Heat up to 80°C for 10 minutes to inactivate enzymes; (4) After centrifugation, filter with ceramic membrane, vacuum concentration concentration is 20%, after sterilization, the material liquid is spray-dried and passed through 60 mesh sieve, measured, packed in compound bags, inspected and put into storage . The raw material requirements for this production method: gluten: moisture ≤ 7.0%, protein ≥ 77...

Abstract

The invention discloses an industrial production method for enzymatic preparing wheat peptide from wheat gluten. The production method is characterized by comprising the following steps: (1) putting wheat gluten of 1kg, adding deionized water, and reflowing to a pot; (2) heating up to 50 to 55 DEG C, pH of feed fluid is 7.5 to 8.0, then adding protamex of 1 to 2g, and carrying out enzymolysis for 8 hours; (3) heating up to 80 DEG C, and extinguishing enzyme for 10min; and (4) carrying out filtration by a ceramic membrane and vacuum concentration, treating the feed fluid with spray drying, sieving by a sieve with 60 meshes, and packing by compound bags. The wheat peptide prepared by the method of the invention has the protein content of above 50 percent, molecular weight of wheat peptide of 90 percent is below 1000Dalton. The method of the invention has simple technique and short production cycle, the wheat peptide product produced by the method is white and has good mouthfeel.

Description

(1) Technical field [0001] The invention relates to a production method of wheat peptide, in particular to an industrial production method of enzymatically preparing wheat peptide from gluten. (2) Background technology [0002] Wheat gluten 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 gluten into wheat peptide can better digest and absorb. At present, the methods for preparing wheat peptides from gluten 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 amount of amino acids. Direct enzymatic hydrolysis with gluten is very difficult. , long time, difficult to filter, and low peptide yield. (3) Contents of the invention [0003] In order t...
