Abstract

The invention discloses HMB-Ca production process method, which comprises the following steps that HMB is dissolved in water; calcium salt is added; stirring, filtering and concentration are performedto obtain an HMB-Ca crude product; the HMB-Ca crude product is added into an alcohol solvent; after stirring, filtering and concentration are performed, an organic solvent is added; stirring and filtering are performed; solid drying is performed to obtain an HMB-Ca product; during the filtering, the hole diameter is 1 to 100 micrometers. The HMB-Ca production process method has the advantages that the production operation and purification filtering conditions of the HMB-Ca product are optimized; the mechanical impurities and the metal ion residues in the HMB-Ca product are effectively reduced; the safety when the HMB-Ca product is used as a health care product and food additive is improved; the process conditions are mild; the operation is easy; the production operation safety degrade isreduced; green and environment-friendly effects are achieved; the industrialization is favorably realized.

Description

technical field [0001] The invention relates to the technical field of organic synthesis, in particular to a production process of HMB-Ca. Background technique [0002] The compound β-hydroxy-β-methylbutyrate calcium, referred to as HMB-Ca, is a metabolite of leucine. HMB-Ca can be used to promote animal muscle growth, enhance the immune ability of mammals, reduce cholesterol and low-density lipoprotein (LDL) levels in the human body to reduce the incidence of coronary heart disease and cardiovascular disease, and can also help the human body to supplement calcium and strengthen the human body. Nitrogen fixation ability to maintain protein levels in the body; therefore, it is widely used and can be added to beverages, milk and dairy products, cocoa products, chocolate and chocolate products, as well as candy, baked goods, and special diets as food additives, dietary additives, and weight loss food additives In food, it can supplement calcium, lose weight, build muscle, enha...
