Abstract

The invention discloses a method for removing isprothiolane in rice protein through ethanol. The method comprises the following steps: (1) removing the isprothiolane for the first time: uniformly mixing the rice protein of which the content of the isprothiolane exceeds a standard and the food-grade ethanol of which the mass concentration is 60-80% so as to obtain a mixture A, performing heating treatment on the mixture A for 30-60 minutes through microwaves under ultrasonic conditions, then filtering the heated mixture A until the moisture content is smaller than 50%, and collecting filter residues; (2) removing the isprothiolane for the second time: uniformly mixing the filter residues obtained in the step (1) and food-grade ethanol of which the mass concentration is 85-95% so as to obtain a mixture B, performing stirring treatment on the mixture B for 1-2 hours when the temperature of the mixture B is controlled to be 50-75 DEG C, then filtering the stirred mixture B until the moisture content is smaller than 55%, and collecting filter residues; and (3) performing post-treatment: washing the filter residues obtained in the step (2) with water, drying the washed filter residues, and crushing the dried filter residues so as to obtain the rice protein of which the content of the isprothiolane is lower than 10ppb. According to the method disclosed by the invention, the removing efficiency of the isprothiolane can reach more than 90%, so that the content of the isprothiolane in the rice protein is lower than 10ppb.

Description

technical field [0001] The invention relates to the technical field of food processing, in particular to a method for removing rice blastin from rice protein with ethanol. 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] Daoblastin has made outstanding contributions...
