Process capable of removing heavy metals and used for processing protein powder from rice

Abstract

The invention discloses a process capable of removing heavy metals and used for processing protein powder from rice. The process comprises the following steps: (1) weighing 100 g of rice with excessive cadmium and adding 0.8 L of a sodium hydroxide solution with a mass concentration of 0.3 wt%; (2) adding 0.8 L of the sodium hydroxide solution with a mass concentration of 0.3 wt% into the rice treated in the step (1) carrying out crushing and wet grinding via a bead mill to obtain rice milk, and allowing the particle size of the rice milk obtained after grinding to be no more than 100 [mu]m; (3) conveying the rice milk obtained in the step (2) to a centrifuge and carrying out centrifugation at a speed of 2000 rpm for 9 min so as to separate rice starch and a rice protein solution; (4) adding 1 L of clear water into the rice starch obtained in the step (3), carrying out rinsing twice, then adding 350 ml of a citric acid solution with a pH value of 4.0 and carrying out stirring with a stirrer at a temperature of 35 DEG C and a speed of 1000 rpm for 4 h; (5) adding the rice starch and rice protein treated in the step (4) into an autoclave; and (6) drying the sterilized rice starch and rice protein in a baking oven with a temperature of 80 DEG C.

Description

technical field [0001] The invention relates to a protein powder food, in particular to a technological process for removing heavy metals by using rice to process protein powder, and belongs to the technical field of food processing. Background technique [0002] Protein is one of the seven essential nutrients for the human body. The human body ingests animal protein and plant protein through daily animal food and plant food. With the increasing awareness of people's health and the improvement of income levels, the normal diet can no longer meet the demand for protein quality, nor meet the consumption requirements of people's healthy diet. Therefore, people process protein-containing animal foods or plant foods to extract high-purity protein raw materials, which are widely used in food, medicine, health care products and other industries for production and processing. Protein intake in a healthier way. Protein is the most important nutrient to ensure the health of the bod...
