Embodiment

[0041] Embodiment, the method steps of this preparation functional protein peptide:

[0042] Step 1. Pretreating the dephenolized cottonseed protein raw material through a 20-40 mesh sieve to remove shells and velvet in the raw material; the used dephenolized cottonseed protein raw material is dephenolized cottonseed protein with a protein content ≥ 50%.

[0043] Step 2. Put the pretreated dephenolized cottonseed protein raw material into the enzymatic hydrolysis reaction kettle, add water and stir; the amount of water added in the enzymatic hydrolysis reaction kettle is 6 to 8 times the quality of the cottonseed protein raw material, and control The temperature of the material is 30-40°C.

[0044] Step 3. Add amylase, cellulase and pectinase combined non-protease in the enzymolysis reaction kettle, and the addition amount accounts for 0.5~0.6‰, 1.0~1.2‰ and 0.4~0.5% of the quality of dephenolized cottonseed protein raw material respectively ‰, after 1-3 hours of enzymatic hy...

Abstract

The invention relates to a preparation method of concentrated protein of cottonseeds and a processing production line thereof, which comprise the following steps: carrying out shell and flocking removal to dephenolized cottonseed protein raw material by a sieve of 20-40 meshes, dissolving the raw material in 6-8 times of water, adding amylase, cellulase and pectinase which respectively account for0.5-0.6 per thousand, 1.0-1.2 per thousand and 0.4-0.5 per thousand in the raw material by mass at the temperature of 30-40 DEG C for 1-3h, inactivating enzyme for 15-20min after temperature is risento 85-90 DEG C; after temperature reduction, adjusting the pH value to 4.0-4.5 by hydrochloric acid and the like for 1-1.5h, and then adjusting the pH valve to be neutral by using NaOH or Ca(OH)2 for1-1.5h; separating materials in a centrifugal machine (filter cloth of 80-100 meshes): conducing spray drying after the filtering liquid is concentrated to 1/5-1/4 volume in vacuum, thus obtaining secondary product (with 35-40% of protein content); and grinding a filter cake after drying in vacuum, thus obtaining the concentrated protein product of cottonseeds (with 65-70% of protein content). Inthe invention, the technology is simple and has no three industrial wastes.

Description

(1) Technical field [0001] The invention relates to the field of deep processing of cottonseed, in particular to a method for preparing concentrated cottonseed protein. (2) Technical background [0002] my country is a major cotton-producing country in the world, and is rich in cottonseed resources, which contain a large amount of high-quality protein. If cottonseed resources are fully utilized, imports of more expensive soybean meal and fishmeal will be greatly reduced. However, the output of high-quality cottonseed protein in my country is very small at present. After removing free gossypol, cottonseed also contains impurities such as shells and velvet, and contains polysaccharides such as starch and fiber. processing and utilization. (3) Contents of the invention [0003] The invention provides a method for preparing cottonseed protein concentrate and its processing production line, which aims to solve the problem of further finishing the dephenolized cottonseed protei...
