CN104322856A - Production technology of rich protein powder - Google Patents

Abstract

The invention discloses a production technology of rich protein powder. The production technology comprises following steps: material selection, foreign matter removing, soaking, a grinding process to obtain a thick liquid, a crude screening process, homogenization, centrifugal separation, concentration, extraction and a drying process. In the invention, a conventional alkali method for extracting rich protein is replaced by the production technology. Broken rice is employed as a raw material and the rich protein is high in quality. The production technology is high in utilization rate of resources and can save resources.

Description

A kind of production technology of rice gluten powder

Technical field

The present invention relates to rice processing technique field, specifically a kind of production technology of rice gluten.

Background technology

The amino acid Compositional balance of rice protein is reasonable, and amino acid content is high, be other vegetable protein incomparable.Rice protein is acknowledged as the food protein of high-quality, meets the idealized model that WHO/FAO recommends.The biological value of rice protein is very high, and it is of high nutritive value, and can compare favourably with egg, cow's milk, beef.In addition, rice protein is low antigen shape albumen, can not produce allergic reaction, is very favourable to production infant food.Rice protein not only has unique trophic function, also has some other health care.Recent research shows, rice protein can reduce the content of serum cholesterol.

The rice gluten that traditional subtraction extracts production department can not reach food-grade.

Summary of the invention

For solving the problem, the invention discloses a kind of production technology of rice gluten powder, its step is as follows:

(1) select materials and choose natural pollution-freely to crack rice without genetically modified;

(2) cracking rice of choosing joins in classification stoner by impurity elimination, and the foreign material in cracking rice are removed by classification stoner;

(3) immersion, defibrination will be cracked rice and be joined fermentation vat, and soak 5-8 hour by deionized water, with grinding-wheel grinder by the wet-milling of cracking rice after immersion, make Rice & peanut milk;

(4) Rice & peanut milk by 60-80 order vibratory sieve, is obtained thin Rice & peanut milk, filters thick slag and return mill by scalping, homogeneous; Thin Rice & peanut milk enters high pressure homogenizer, controlled pressure 300-600 ㎏/cm2, by thin Rice & peanut milk homogeneous to particle less than 2 μm;

(5) centrifugation adopts centrifuge to be separated, and light phase (protein) is separated automatically with heavy phase (starch), gets light phase (protein), and heavy phase (starch) is for subsequent use;

(6) concentrated light phase (protein) being joined in concentration tank concentrates;

(7) extract light phase condensing protein and squeeze into mixing kettle, refine further, entering reverse osmosis membrane, trap water soluble polysaccharide, permeate is pure water, can be recycled, and filters the aleuroplast spraying dry retained, obtains edible rice gluten powder, packaging warehouse-in; Counter-infiltration retains drying, obtains rice polysaccharide, for subsequent use.

The present invention is a kind of production technology of rice gluten powder, selects and cracks rice as raw material, cost-saving; Be separated with rice starch by rice gluten with centrifuge by homogenizer, the rice gluten produced is edible protein; The starch obtained in production, rice polysaccharide have very high value.

The present invention changes the method that traditional subtraction extracts rice gluten, and utilize and crack rice as raw material, the rice gluten quality of production is high, and resource utilization is high, economizes on resources.

Detailed description of the invention

Below in conjunction with specific embodiment, the present invention is further elaborated, but is not limited to the following examples:

Embodiment 1

(1) select materials and choose natural pollution-freely to crack rice without genetically modified;

(2) cracking rice of choosing joins in classification stoner by impurity elimination, and the foreign material in cracking rice are removed by classification stoner;
