Embodiment 1

[0016] The corn water directly enters the ion-exchange resin column without impurity removal through the velocity flow tank, and includes the following steps in turn:

[0017] Adsorption: Take 105m3 of corn soaking water with an organic phosphorus content of 0.6%, and put it into 7 tons of treated anion exchange resin, the resin model is D305, and the flow rate of the sample is controlled at 2 times the column volume per hour.

[0018] Analysis and elution: Blow off the corn water remaining in the column with compressed air, enter 1 column volume of tap water in the opposite direction, prepare 5% hydrochloric acid to elute the resin at a rate of 2 column volumes per hour, and the elution time is 2 hours. Then use compressed air to blow off the eluent in the column, wash the resin with 1 times the column volume of tap water, and mix to obtain the eluent.

[0019] Neutralization: prepare a 10% suspension with calcium hydroxide, and gradually adjust the eluent to pH7.

Abstract

The invention relates to a separation and purification method for phytine, which specially comprises the following steps: (1) sedimentation processing; (2) resin adsorption; (3) desorption elution; (4) neutralization and precipitation; and (5) sheet frame filtering. According to the invention, the insoluble protein content of corn water is greatly reduced, the problem the hybridization column is blocked by corn water is completely solved, the protein content of phytine is reduced, and the quality and yield of phytine are further improved. And through the adoption of a novel adsorption resin, the yield of products is significantly improved.

Description

technical field [0001] The invention relates to a method for producing phytin, in particular to a separation and purification method for producing phytin from corn soaking water. Background technique [0002] The use of corn water or rice bran extract to produce phytin is the main method for domestic industrial production of inositol raw materials. Its specific production methods are mainly divided into traditional methods and adsorption separation. [0003] The traditional method is to directly add quicklime to corn water to generate phytin, which makes the waste water unusable and pollutes a lot. Although the general resin adsorption method overcomes some pollution problems of the traditional method, the adsorption resin is easily blocked due to the large amount of soluble protein in the corn water, which requires a lot of labor and time to clean, and will also bring about a decline in the yield of phytin. rate of decline. The protein in corn water will also cause fouli...
