Calcium phytate purification method

Abstract

The invention relates to a calcium phytate purification method. According to the invention, a calcium phytate crude product is crushed, and is dissolved with saturated hydrochloric acid; filtering is carried out and a filtrate is kept; sodium hydroxide is added into the filtrate until the pH value is higher than 8, while stirring is continuously carried out; filtering is carried out; the filtrate is removed, and a precipitate is kept; the precipitate is washed 2-4 times with distilled water, and is washed 2-4 times with ethanol; and the washed calcium phytate is dried, wherein a drying temperature is controlled at 60-80 DEG C. The calcium phytate provided by the invention has high purity, and can be applied in food and medicine. The process is simple, and the cost is low.

Description

technical field [0001] The invention relates to a method for preparing biochemical products, in particular to a method for purifying calcium phytate. Background technique [0002] As a chelating agent, antioxidant, preservative, water softener, fermentation accelerator, metal anticorrosion agent, etc., calcium phytate is widely used in food, medicine, paint coatings, daily chemicals, metal processing, textile industry, plastic industry and Polymer industry and other industries. Generally, the preparation of calcium phytate is made from plants through acid hydrolysis, alkali precipitation and other process routes. The resulting product has low purity and low value. The preparation of high-quality calcium phytate often requires membrane technology, the process is complicated, and the production cost is high. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a new method for purifying calcium phytate aiming at the d...
