Problems solved by technology

At present, the methods for preparing corn protein peptides from corn gluten powder 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 corn gluten solution, Difficulty, long time, difficult to filter, low peptide yield

Embodiment Construction

[0023] Accompanying drawing is a kind of specific embodiment of the present invention. As shown in Figure 1, this embodiment includes the following steps:

[0024] 1. Raw material requirements

[0025] ③ Corn Gluten Powder: Moisture ≤6.0%, Protein ≥64%, Ash ≤2.0%

[0026] ④Ion-free water: PH7.5-10 conductivity≤50us / cm

[0027] ⑤Enzyme preparation: α high temperature amylase 20000u / g alkaline protease 360000u / g

[0028] Neutral protease 130000u / g

[0029] 2. Put in 1kg of corn gluten powder, add 11500-7500ml of deionized water (sizing concentration 8-12%) after feeding, heat at 95-98°C and soak for 1 hour, and cut through the emulsifying shear at the bottom of the tank. and flow back into the tank.

[0030] 3. Add 15-20ml of 30% calcium hydroxide to adjust the pH of the feed solution to 6.5-7.0 and heat to 95-98°C, add 6.25-8.0ml of 0.625-0.8% α high-temperature amylase, and start enzymatic hydrolysis. 0.5 hours pH6.0-6.4 plus 30% calcium hydroxide 8-15ml pH6.5-7.0, 1.5 h...

Description

(1) Technical field [0001] The invention relates to high-purity corn protein polypeptide industrial products, in particular to an industrial production method for enzymatically preparing corn protein polypeptide from corn gluten powder. (2) Background technology [0002] Corn 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. Using corn gluten powder to prepare corn gluten polypeptide can better digest and absorb. At present, the methods for preparing corn protein peptides from corn gluten powder 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 corn gluten solution, It is difficult, takes a long t...
