Problems solved by technology

In the preparation method disclosed by the Chinese patent CN101505731A and CN101505730A of the Procter & Gamble Company of the United States, the molar ratio of citric acid to malic acid is about 30:70 to about 80:20, and the preparation method is to react at a peak temperature of 45-70°C and then cool to 40°C , forming a calcium citrate malate precipitate, and then drying to obtain the product. The preparation process of this method requires a cooling process and a process of separating the precipitate from the reactant, which consumes a lot of energy. Therefore, the applicability of this method needs to be further improved.
[0005] The preparation method of CCM disclosed in domestic and foreign patent documents is usually prepared by neutralization reaction of citric acid, malic acid and calcium carbonate, and needs to go through multiple steps such as neutralization reaction, crystal precipitation, filtration and drying, and the preparation efficiency is low. The loss rate and energy consumption are large, and there is still room for improvement in the water solubility, quality and production cost of the correspondingly prepared calcium fruit acid

Abstract

The invention discloses a method for preparing calcium citrate and malate, relating to a method using calcium carbonate, citric acid and L-malic acid to prepare the calcium citrate and malate. The method comprises the following steps: preparing the calcium carbonate, the citric acid and the L-malic acid, wherein the mole ratio is 4-9 to 2-4 to 2-5; mixing the citric acid and the L-malic acid, and adding water to prepare a solution, wherein the ratio between the quality of the water and the total quality of raw materials is 1 to 0.5-3; then adding the calcium carbonate into the solution, and evenly stirring to obtain a mixture; standing the mixture at normal temperature for 30-120 min; and drying and crushing. The method does not need the process of solid-liquid separation and recovery of calcium, the obtained product has fine mouth feel, no grit feel and good taste and is used as food or health food additives not to affect the mouth feel. Accordingly, on the basis that high solubility and fine mouth feel of the product are ensured, the method simplifies the production process, can greatly reduce the production cost, and is suitable for industrial mass production.

Description

【Technical field】 [0001] The invention relates to a method for preparing calcium citrate malate by utilizing calcium carbonate, citric acid and L-malic acid. 【Background technique】 [0002] Calcium citrate malate (Calcium citrate malate, CCM), also known as calcium fruit acid, is an organic chelate synthesized by calcium, citric acid and malic acid in a certain proportion. Calcium citrate malate is a new type of calcium nutrient fortification Its solubility is significantly enhanced compared with calcium citrate and calcium malate, which makes calcium fruitate have higher biological absorption and availability of calcium. At the same time, calcium citrate malate has the ability to prevent the elderly and osteoporosis patients from Tooth loss does not affect the absorption of trace elements such as iron, zinc, selenium and magnesium, does not increase the risk of kidney stones, lowers blood pressure, regulates blood lipids, and promotes intestinal health and other important p...
