Embodiment 1

[0029] A kind of method that hydrogen peroxide and ethanol remove rice blastin in rice protein under neutral condition, comprises the following steps:

[0030] (1) Hydrogen peroxide treatment: Mix rice protein with a rice blasting content of 200ppb and food-grade hydrogen peroxide with a mass concentration of 3% at a weight ratio of 1:7, and add ferric chloride with a weight of 3% of rice protein to mix. pH to 7.0, stirred for 2 hours, filtered to obtain filter residue;

[0031] (2) Ethanol treatment: Mix the filter residue obtained in step (1) with a food-grade ethanol solution with a mass concentration of 80% at a weight ratio of 1:7, stir at 75°C for 1.5 hours, and filter until the water content is below 55% to obtain the filter residue;

[0032] (3) Post-processing: wash the filter residue obtained in step (2), dry (temperature 60°C, time 3h), sterilize (temperature 80°C, time 3h), and crush the sterilized material to 200-1000 mesh To obtain rice protein with a rice blast...

Embodiment 2

[0034] A kind of method that hydrogen peroxide and ethanol remove rice blastin in rice protein under neutral condition, comprises the following steps:

[0035] (1) Hydrogen peroxide treatment: Mix rice protein with a content of 100 ppb rice blasting spirit and food-grade hydrogen peroxide with a mass concentration of 3% in a weight ratio of 1:6, and add ferric chloride with a weight of 3% of rice protein to mix. pH to 7.0, stirred for 1.5h, filtered to obtain filter residue;

[0036] (2) Ethanol treatment: Mix the filter residue obtained in step (1) with a food-grade ethanol solution with a mass concentration of 90% at a weight ratio of 1:6, stir at 35°C for 2 hours, and filter until the water content is below 55% to obtain the filter residue;

[0037] (3) Post-processing: wash the filter residue obtained in step (2), dry (temperature 60°C, time 3h), sterilize (temperature 80°C, time 3h), and crush the sterilized material to 200-1000 mesh The rice protein with rice blasting s...

Embodiment 3

[0039] A kind of method that hydrogen peroxide and ethanol remove rice blastin in rice protein under neutral condition, comprises the following steps:

[0040] (1) Hydrogen peroxide treatment: Mix rice protein with a content of 200 ppb rice blasting spirit and food-grade hydrogen peroxide with a mass concentration of 5% in a weight ratio of 1:5, and add ferric chloride with a weight of 5% of rice protein to mix. pH to 6.5, stirred for 2 hours, filtered to obtain filter residue;

[0041] (2) Ethanol treatment: Mix the filter residue obtained in step (1) with a food-grade ethanol solution with a mass concentration of 95% at a weight ratio of 1:4, stir at 65°C for 2 hours, and filter until the water content is below 55% to obtain the filter residue;

Abstract

The invention discloses a method for desorbing isoprothiolane in rice protein through hydrogen peroxide and ethyl alcohol under a neutrality condition. The method comprises the following steps that firstly, treatment through hydrogen peroxide is carried out, wherein the rice protein with the isoprothiolane exceeding the standard and hydrogen peroxide with the mass concentration of 0.5-5% are mixed according to the weight ratio of 1:4-7, the pH is regulated to be 6.5-7.5, stirring treatment is carried out for 1-2 h, filtering is carried out, and filtering residues are obtained; secondly, treatment through ethyl alcohol is carried out, wherein the filtering residues obtained in the first step and an ethyl alcohol solution with the mass concentration higher than 60% are mixed according to the mass ratio of 1:4-7, stirring treatment is carried out for 1.5-2 h at the temperature of 35 DEG C-75 DEG C, filtering is carried out until the moisture is lower than 55%, and filtering residues are obtained; thirdly, post-treatment is carried out, wherein the filtering residues obtained in the second step are washed with water, dried and sterilized, the sterilized materials are smashed, and the rice protein with the isoprothiolane content lower than 10 ppb is obtained. By means of the method, the isoprothiolane desorbing rate can reach higher than 90%, the technology is simple, operation is convenient, and the method is suitable for mass production.

Description

technical field [0001] The invention relates to the technical field of food processing, in particular to a method for removing blastazin from rice protein with hydrogen peroxide and ethanol under neutral conditions. Background technique [0002] The pollution of soil environment caused by the use of pesticides has aroused widespread concern. With the continuous development of spraying technology, the utilization rate of pesticides has been greatly improved. For example, electrostatic spraying technology can increase the effective utilization rate of pesticides to 90%. However, due to various reasons, this technology cannot be popularized and applied in production. The traditional pesticide application technology allows pesticides to enter the soil after application, so that the soil becomes the "storage" and "distribution center" of pesticides in the environment. Pesticide pollution has become an important topic and hot issue in agricultural development research. [0003] D...
