Problems solved by technology

Inorganic salt nutrient enhancers have their obvious weaknesses: (1) prone to hydrolysis in the human body; (2) inorganic anions, such as sulfate ions, can stimulate the intestinal tract, which not only affects the absorption of trace elements in the intestinal tract, but also causes nausea , diarrhea, etc.; (3) Inorganic salts also affect the stability of vitamins
The organic acid salt nutrition enhancer of essential element also has its weak point, as EDTA iron as nutrition enhancer (Chinese patent application No. 98100374), because of its particularly stable and poor absorption; Saccharin zinc enhancer (Chinese patent application No. 95104822), due to It is unsuitable to use due to the debate on its effect on the human body

Embodiment 1

[0020] Accurately weigh 0.15 mole of Na 2 CO 3 , 0.1 mol K 2 CO 3 And 1.5 moles of glutamic acid. Dissolve it in water to make a nearly saturated aqueous solution, accurately weigh 0.5 moles of ZnCO 3 Add a small amount of water and stir it into a slurry. Add the glutamic acid solution to Na in 3 times under constant stirring 2 CO 3 , K 2 CO 3 And ZnCO 3 In suspension. The reaction temperature is controlled at about 40°C. Continuous CO during the reaction 2 The bubbles are released and the glutamic acid complex is continuously generated. When CO 2 After the bubbles stop emitting, it indicates that the above-mentioned reaction is basically completed, after which the reaction is continued for 0.5 hours to ensure the quantitative production of the target product. The product is evaporated and concentrated to precipitate the target product, filtered, and dried to obtain the multifunctional composite nutrition fortifier of the present invention, the product chemical formula Na 0.3 K 0....

Abstract

The preparation method of the invented compound zinc, potassium and glutamic acid nutrient enriching agent includes the following steps: according to chemical metering weighing zinc carbonate, adding water and stirring to obtain paste material, mixing the obtained zinc carbonate paste material with saturated solutions of sodium carbonate and potassium carbonate, stirring them and adding glutamic acid solution into the above-mentioned mixed solution in three times while stirring, reaction temp. is controlled at 40-55 deg.C, and making reaction until it has no production of bubble, continuously reacting for 0.5-1.0 hr., evaporating and concentrating, filtering, separating out product, drying so as to obtain its object product, its yield is 95.6%-97.3%. The chemical formula of the invented product is also disclosed.

Description

Technical field: [0001] The invention belongs to the category of nutrition fortifiers, and specifically relates to a compound zinc and potassium glutamate complex nutrition fortifier. [0002] The invention also relates to a preparation method of the above-mentioned nutritional fortifier. Background technique: [0003] There are about 100 kinds of zinc enzymes in the human body. Zinc is mainly involved in the formation of the active centers of these enzymes to maintain the structural stability of the enzymes and the normal functioning of their functions. Zinc has a very close relationship with human body's growth and development, immune defense, wound healing, reproduction and fertility. The results of my country's nutrition survey and total diet study show that according to the current diet of the Chinese people, the daily intake of zinc is far from the standard, so the people of our country are suffering from zinc deficiency. Lack of zinc leads to symptoms such as growth delay,...
