Problems solved by technology

It can also be treated with α-amylase to hydrolyze starch to low molecular weight water-soluble sugars to separate proteins, but this enzymatic method must be gelatinized and then liquefied at a temperature above 100°C, and the protein in rice has been completely denatured, so it is not suitable for milk powder and rice. Raw material of liquid milk

Embodiment 1

[0013] Take 100kg of crushed rice, add 500kg of hot water at 50°C, and soak for 5 hours; then add water to grind with a grinder refiner to obtain 1000kg of slurry, pass through a 60-mesh sieve to remove impurities such as fibers; use a high-pressure pump to pump the sieved liquid into high-pressure Homogenizer, maintain pressure at 210kg / cm 2 Send the homogeneous liquid into the hydrocyclone unit to separate the light phase and the heavy phase; dehydrate the light phase flowing out from above to obtain a wet cake containing 25% protein (dry basis), put it into the preparation pot, and add reducing gum 0.5kg, 0.2kg of monoglyceride, 0.1kg of sucrose ester and various flavoring agents, then homogeneously emulsify, and finally spray dry the thick liquid to obtain 30kg of milk powder.

Embodiment 2

[0015] Take 50kg of crushed rice, add 200kg of hot water at 40°C, soak for 5 hours; pass the slurry through a 60-mesh sieve, 2 Homogenize under pressure; add purified water to the homogenized solution to 200kg, 0.4kg sucrose ester, 4kg salad oil, 0.5kg carboxymethyl cellulose, and homogenize to obtain 200kg rice protein milk, which can be sterilized.

Embodiment 3

[0017] Take 500kg of broken rice, add 2500kg of hot water at 50°C, soak for 4 hours, refine the pulp, pass through a 60-mesh sieve to remove impurities such as fibers, and inject the filtrate at a pressure of 200kg / cm 2 High-pressure homogenizer; the homogeneous liquid is separated by a disc separator, and the material enters from the middle, and the overflow pipe is the light phase containing protein, throwing water, vacuum drying and dehydration at a vacuum degree of 720mmHg, and 50°C to obtain 150kg of milk powder.

Abstract

The invention relates to a new method for preparing rice gluten milk powder and rice gluten milk by using crushed rice and belongs to the technical field of natural protein separation and extraction as well as deep processing. According to the characteristic that starch grain in rice endosperm is combined with proteosome, physical high-pressure homogenized splitting method is adopted for splitting the thin cell wall of amyloplast, and the split starch and protein are centrifugalize according to the difference of specific weight, and the protein in light phase is concentrated, formulated and formed to prepare the milk powder and fluid milk. The method completely maintains the physicochemical property of natural rice protein, is high in extraction rate, concise in process and low in cost and avoids the three wastes.

Description

1. Technical field [0001] The invention discloses a method for extracting protein processed milk powder and liquid milk from broken rice, which belongs to the technical field of separation, extraction and deep processing of natural protein. 2. Background technology [0002] In my country, 20 million tons of crushed rice are produced every year, which cannot be further processed and utilized. It contains high-quality protein with a biological value as high as 77% and a digestibility of 94%, which is the highest among grains. The biological value is equivalent to that of beef, fish and shrimp Soy, corn, wheat are all much higher. Rice protein can be processed into high-quality milk powder for infants and young children, and rehabilitation nutrition for the middle-aged and elderly and the sick and weak. If 7 million tons of broken rice can be processed, that is, 1 / 3 of the total amount, 600,000 tons of protein can be obtained, which is equivalent to the sum of all proteins cont...
