Embodiment 1

[0018] Disperse the rice protein in water, the ratio of solid to liquid is 1:10, stir and mix well, adjust the pH value of the above rice protein dispersion to 7 with 1mol / L NaOH solution, store the obtained material in a transparent bag, and carry out electron beam irradiation treatment , the irradiation dose is 60KGy. The pH value of the obtained liquid is adjusted to 7.5 with HCl solution, and spray-dried to obtain a high-soluble rice protein product.

Embodiment 2

[0020] Disperse the rice protein in water, the ratio of solid to liquid is 1:15, stir and mix well, adjust the pH value of the above rice protein dispersion to 8 with 0.5mol / L NaOH solution, store the obtained material in a transparent bag, and carry out electron beam irradiation treatment, the irradiation dose is 2KGy. The pH value of the obtained liquid is adjusted to 7.5 with HCl solution, and spray-dried to obtain a high-soluble rice protein product.

Embodiment 3

[0022] Disperse the rice protein in water, the ratio of solid to liquid is 1:13, stir and mix well, adjust the pH value of the above rice protein dispersion to 12 with 1.5mol / L NaOH solution, store the obtained material in a transparent bag, and carry out electron beam irradiation treatment, the irradiation dose is 100KGy. The pH value of the obtained liquid is adjusted to 7.5 with HCl solution, and spray-dried to obtain a high-soluble rice protein product.

Abstract

A method for improving rice protein solubility through combined use of an alkaline method and electron beam irradiation comprises steps as follows: rice protein is taken as a raw material, spray drying is performed after alkaline liquor treatment, electron beam irradiation and acid neutralization, and a high-solubility rice protein product is obtained. The solubility of protein powder prepared with the method can be improved by about 20 times, the utilization rate and the additional value of the rice protein are greatly increased, and the method has wide application prospect.

Description

technical field [0001] The invention relates to the technical field of intensive processing of agricultural products and the comprehensive utilization of by-products thereof, in particular to a method for improving the solubility of rice protein by combined use of alkaline electron beam irradiation. Background technique [0002] Rice protein is a high-quality protein with high nutritional quality. It not only has a very reasonable amino acid composition, but also does not contain similar allergens, and is hypoallergenic. The biological value (BV) of rice protein is 77, and the protein utility ratio (PER) is 1.36-2.56, so the utilization rate of protein is higher than that of other grains. Rice dregs is a kind of rice protein with low price and high quality. In the production of starch sugar, every 7 tons of rice consumed will produce 1 ton of rice dregs, which is a considerable amount. The dry basis rice protein content in rice dregs is 40% to 65%, but due to its poor water...
