Abstract

The invention relates to a method for removing copper and mercury in bitter apricot seed protein. The method comprises the following steps: taking bitter apricot seed protein, performing size mixing, substituting, chelating, hardening and tempering, adsorbing, performing solid-liquid separation, adjusting the pH value, sterilizing, dehydrating, drying and the like. By adopting the method, the contents of copper and mercury in the bitter apricot seed protein can be effectively reduced, and moreover the sensory quality and the nutrient values of the bitter apricot seed protein are not affected.

Description

technical field [0001] The invention relates to a method for removing copper and mercury in almond protein, belonging to the field of agricultural product processing. Background technique [0002] Almond protein has a good amino acid composition ratio and high digestibility. It is an excellent vegetable protein and has important utilization value. In recent years, with the development of industry and mining, the problem of heavy metal pollution has gradually been exposed. Copper and mercury are attached to protein, which affects the food safety of protein. After being eaten, proteins rich in copper and mercury can be enriched in organisms, seriously endangering human health. Contents of the invention [0003] The invention aims to provide a method with simple method and reasonable cost to reduce the content of copper and mercury in almond protein and improve food safety. [0004] A method for removing copper and mercury in almond protein, comprising the following steps:...
