Embodiment 1

[0051] Embodiment 1: Preparation of L-arginine zinc citrate

[0052]

[0053] Dissolve 21 grams (0.1 mol) of citric acid monohydrate in 100 ml of water, add 8.1 grams (0.1 mol) of zinc oxide, dissolve at room temperature, filter the solution after it is transparent, and remove SiO in zinc oxide 2 Wait for impurities, add 17.4 grams (0.1mol) of L-arginine to the clean filtrate, stir and react at 70-80°C for 4 hours, then drop the reaction solution into absolute ethanol for crystallization, cool down and filter to dry, the obtained 42.2 grams of L-arginine zinc citrate salt has good fluidity and moisture absorption resistance, and the yield is 98.2%.

[0054] [α] D 20 =+5.4°(C=5,H 2 O), L-arginine HPLC content 41.1%, citric acid HPLC content 43.8%, zinc content 15.1%.

Embodiment 2

[0055] Embodiment 2: the preparation of L-lysine citrate zinc salt

[0056]

[0057] Dissolve 21 grams (0.1 mol) of citric acid monohydrate in 100 ml of water, add 9.9 grams (0.1 mol) of human zinc hydroxide, dissolve at room temperature, filter the solution after it is transparent, and remove SiO in zinc hydroxide 2 Wait for impurities, add 14.6 grams (0.1mol) of L-lysine to the clean filtrate, stir and react at 70-80°C for 2 hours, then drop the reaction solution into absolute ethanol for crystallization, cool down, filter and dry, and the resulting 39.2 grams of L-lysine citrate zinc salt has good fluidity and moisture absorption resistance, and the yield is 97.6%.

[0058] [α] D 20 =+4.4°(C=5,H 2 O), L-lysine HPLC content 36.8%, citric acid HPLC content 47.0%, zinc content 16.2%.

Embodiment 3

[0059] Example 3: Preparation of L-carnitine zinc citrate.

[0060]

[0061] Dissolve 21 grams (0.1 mol) of citric acid monohydrate in 100 ml of water, add 12.5 grams (0.1 mol) of zinc carbonate, dissolve at room temperature, filter the solution after it is transparent, and remove SiO in zinc carbonate 2 Wait for impurities, add 16.1 grams (0.1mol) of L-carnitine to the clean filtrate, stir and react at 70-80°C for 8 hours, then drop the reaction solution into absolute ethanol for crystallization, cool down and filter to dry, the obtained L-carnitine - 40.7 grams of carnitine citrate zinc salt, which has good fluidity and moisture absorption resistance, and the yield is 97.6%.

[0062] [α] D 20 =-10.8°(C=5,H 2 O), L-carnitine HPLC content 38.2%, citric acid HPLC content 45.8%, zinc content 16.0%.

Abstract

Embodiments of the invention provide a composite zinc citrate salt, a preparation method of the same, a composition containing the same, and purposes thereof. The composite zinc citrate salt has a following structural general formula, wherein R represents basic amino acid, L-carnitine or alkanoyl L-carnitine, and an alkanoyl group is a linear or branched alkanoyl group having 2-5 carbon atoms. Accordingly, the composite zinc citrate salt makes zinc citrate combine with the basic amino acid, the L-carnitine and / or the alkanoyl L-carnitine to form the composite zinc citrate salt which has the characteristics of being convenient to preserve and transport, being easy to be absorbed by a human body, and the like, and has various forms, physicochemical properties of a single complex zinc citratesalt are greatly improved, and functions of the basic amino acid, the L-carnitine and / or the alkanoyl L-carnitine are increased, thereby greatly expanding an application range of the composite zinc citrate salt.

Description

technical field [0001] The invention particularly relates to a compound zinc citrate salt, its preparation method, its composition and its use. Background technique [0002] Natural citric acid is widely distributed in nature. Natural citric acid exists in the bones, muscles and blood of plants such as lemons, citrus, pineapples and other fruits and animals. Synthetic citric acid is obtained by fermenting sugar, molasses, starch, grapes and other sugar-containing substances, and can be divided into anhydrous and hydrate. Pure citric acid is colorless transparent crystal or white powder, odorless, with an attractive sour taste. [0003] There have been many reports on the efficacy of citric acid, and it has multiple functions: Because citric acid has a mild and refreshing sour taste, it is widely used in the manufacture of various beverages, soft drinks, wine, candies, snacks, biscuits, canned juices, dairy products and other foods. It is also used as a flavoring agent and ...
