Problems solved by technology

Among them, all patents except the patent (02153835.0) are all about recovering and refining rice protein while preparing rice starch. The rice protein extracted by this method is not conducive to human digestion because it has not been denatured by heat and enzymatically hydrolyzed. and absorption
In addition, this kind of rice protein extraction process is subject to the following factors: a. It must match the production or application of rice starch; b. It needs to consume a lot of water resources and produce a huge amount of industrial wastewater
[0003] Patent No. (02153853.0) "New Process for Extracting Rice Protein from Rice Grains" proposes a method of extracting rice protein from rice grains with compound enzymes, but this method still uses alkali-dissolved protein after enzymatic treatment of rice grains. The acid precipitation process, the production and operation process is cumbersome, and consumes a lot of acid, alkali and water, which also pollutes the protein itself and the environment
[0004] In addition, the rice protein that can be obtained by using all the aforementioned techniques is in the form of powder. For some occasions with special requirements, the rice protein used is required to be in the form of granules and have good sensory effects (for example, the granules can be lifelike. accurately reflect the grain morphology of rice), obviously, the aforementioned technology cannot meet this special requirement

Embodiment 1

[0028] Select 600kg of high-quality rice, add 3000kg of water to the rice, and add 1.2×10 high-temperature α-amylase to the above-mentioned rice with water 7 Stir and adjust the pH to 5.0 after the unit, heat the temperature to 90°C for enzymolysis, and the time for enzymolysis is 200 minutes. After the enzymolysis is completed, the rice protein and enzymolysis solution are pumped into the filter press with a centrifugal pump for pressure filtration. Through the action of pressure and filter cloth, the rice protein and enzymolysis solution can be separated from solid to liquid. The conditions of pressure filtration are relatively simple, as long as the pressure of the centrifugal pump reaches above 0.15mpa. Granular rice protein can be obtained after drying at 80°C and a vacuum of -0.05mpa for 6 hours; the enzymatic hydrolysis solution separated by pressure filtration can be further processed to obtain by-products such as glucose, monosodium glutamate, and citric acid. From the...

Embodiment 2

[0030]Select 600kg of high-quality rice, add 1200kg of water to the rice, and add 1.2×10 high-temperature α-amylase to the above-mentioned rice with water 7 Stir and adjust the pH to 6.0 after the unit, heat the temperature to 110°C for enzymolysis, and the time for enzymolysis is 100 minutes; after the enzymolysis, use a centrifugal pump (or use a high-level self-flow) to introduce the rice protein and enzymolysis solution into a vacuum suction The filter machine, through the action of vacuum and filter cloth, sucks out the liquid phase in the enzymatic hydrolysis solution to realize solid-liquid separation; the conditions for suction filtration separation are relatively simple, and the vacuum degree of suction filtration can reach above -0.07mpa; through suction filtration separation Finally, the granular rice protein filter cake and enzymolysis solution are obtained, and the granular rice protein filter cake obtained above is dried for 4 hours at a temperature of 90°C and a ...

Embodiment 3

[0032] Select 600kg of high-quality rice, add 1500kg of water to the rice, and add high-temperature α-amylase 2.4×10 to the above-mentioned rice with water 7 Stir after the unit and adjust the pH to 7.0, and heat the temperature to 100° C. for enzymolysis, wherein the enzymolysis time is 60 minutes. After the end of enzymolysis, the rice protein and enzymolysis solution are introduced into the centrifuge with a centrifugal pump (or using high-level self-flow), and the solid-liquid separation is realized through the centrifugal action of the material in the high-speed rotating centrifuge and the function of the centrifuge screen. Condition: The separation factor of the centrifuge is >500. Granular rice protein filter cake and enzymatic hydrolysis solution are obtained after centrifugation, and the granular rice protein filter cake obtained above is dried for 2 hours at a temperature of 95°C and a vacuum of -0.03mpa to obtain a granular Rice protein; by-products such as glucose...

Abstract

The invention discloses a particle-shaped rice protein and preparing method and application, which is characterized by the following: hydrolyzing the rice through amylase to do solid-liquid separationand dry to obtain the rice protein with appearance as similar as the shape of rice particle;displaying good organoleptic effect; fitting for manufacturing dilated food directly or being auxiliary material to reinforce the nourishment, especially for the content of amino acid.

Description

technical field [0001] The present invention relates to a kind of rice protein, more specifically, the present invention relates to a kind of granular rice protein, and the present invention also relates to a kind of preparation method of said rice protein and its application in food. Background technique [0002] Rice protein has excellent nutritional value, and its nutritional value is much higher than that of wheat protein, soybean protein, etc. Although the lysine content is limited, it is much higher than other cereals, and the amino acid composition is relatively reasonable; the biological value of rice protein and The protein utility ratio is high, and the hypoallergenicity of rice protein makes it very suitable as food for infants or other special populations; in recent years, foreign studies have shown that rice protein also has potential health care effects. Studies have shown that compared with casein, the processed high-purity rice protein has a more significant ...
