Abstract

The invention relates to a new substance, namely zinc ascorbate hydrogen citrate, as well as a preparation method and an application thereof. The preparation method of the zinc ascorbate hydrogen citrate is characterized by comprising the following steps: (1) weighing raw materials, namely citric acid monohydrate, ascorbic acid, zinc oxide and water, and putting into a reaction kettle, wherein the weight ratio of the substances, namely the citric acid monohydrate, the ascorbic acid and the zinc oxide is 3: 1: 4; (2) starting a machine for performing chemical reaction for half an hour; (3) stopping the machine for half an hour, adding ethanol and enabling the chemical reaction to be mature; and (4) starting the machine for half an hour, and releasing the zinc ascorbate hydrogen citrate. The zinc ascorbate hydrogen citrate prepared by the preparation method provided by the invention can be dissolved in water, be conductive to absorption by people and animals, and be used as a zinc supplement Vc anti-oxidation preservative, a zinc supplement Vc food additive or medicines for treating bad appetite, dysplasia, stomach diseases, bronchitis, asthma, pneumonia, hepatitis, liver cancer and hypertension.

Description

technical field [0001] The invention relates to the field of biochemical industry, medicine and food, in particular to zinc hydrogen citrate ascorbate and its preparation method and application. Background technique [0002] Zinc citrate in the biochemical, pharmaceutical and food markets at home and abroad today, English name: Zinc Citrate, molecular formula: Zn 3 (C 6 h 5 o 7 ) 2 2H 2 O, with a purity of 98.0-100.5% or more (medicine and food grade), is a white crystalline powder. It is a smart food additive for zinc supplementation and a medicine for treating loss of appetite and dysplasia. However, because it is insoluble in water, it is difficult for humans and animals to absorb. make its use restricted. [0003] The main function of ascorbic acid (abbreviated as Vc, also known as vitamin C) is to improve immunity, prevent cancer, heart disease, stroke, protect teeth and gums, etc. The reductive properties of Vc can eliminate the nitroso and free radicals that ca...
