Method for preparing easily dissolved zinc glycine

Abstract

The invention discloses a method for preparing easily dissolved zinc glycine, which comprises the following steps: respectively taking 15 to 15 weight percent of glycin, 5 to 10 weight percent of zinc oxide and 76 to 80 weight percent of water, mixing and stirring the raw materials in a reaction kettle to make the raw materials fully dissolved, performing reaction for 3 to 24 hours by heating at a temperature between 50 and 80 DEG C, and then standing for 6 to 10 hours; taking reaction solution, and centrifugating the reaction solution at a rotating speed between 3,000 and 8,000 turn / minute, taking sedimentation by the centrifuging, drying the sedimentation at a temperature between 80 and 120 DEG C in an oven to obtain a dry substance; and crushing the dry substance, passing through a 80 to 120-mesh sieve, performing sterilizing and split charging. The method for preparing the zinc glycine has easily obtained raw material used, scientific and reasonable mixture ratio of the raw materials, simple preparation process, high yield of the synthesized zinc glycine, low cost and suitability for industrial production.

Description

technical field [0001] The invention discloses a preparation method of a compound, in particular discloses a preparation method of easily soluble zinc glycinate. Background technique [0002] People of different ages and occupations in my country generally have low zinc intake. The average daily zinc intake per person is only about 50% of the zinc intake recommended by the Chinese Nutrition Society. The phenomenon of zinc deficiency in children and adolescents is even more serious. Seriously, there are 50% to 60% of children and adolescents whose zinc intake is less than 50% of the recommended supply. Zinc is one of the 14 essential trace elements in the human body. It has important biological functions and is important for human health. Growth and development play an important role, and zinc can enhance the body's immunity, ensure the normal development of reproductive function, and promote the metabolism of cholesterol and high-density lipoprotein. [0003] At present, most...

Problems solved by technology

[0003] At present, most of the human body zinc supplement products used in China are the first-generation inorganic zinc and the second-generation common organic salt zinc. Among them, the first-generation zinc supplements are actually zinc oxide or zinc carbonate, which are in an ionic state. The stomach is very irritated, and it is difficult to absorb the supplemented zinc nutrition. If long-term use or excessive use can easily cause stones or indigestion in the body, the second-generation zinc supplement (common organic salt zinc supplement), this type of zinc is usually: lactic acid The absorption rate of zinc, glucose zinc or licorice zinc, etc. in the human body is generally only 30% or lower, and there is not much improvement compared with the first category of products

Zinc glycinate is a small molecule organic zinc with biological activity, but the solubility of current zinc glycinate is poor, the human body absorption rate is low, and the preparation method of zinc glycinate at present, the synthesis rate of the finished product is low, the process is complicated, and the cost is high
