Preparation method of lysine chelated calcium melon-seed-like microcapsule oral preparation
The invention discloses a preparation method of a lysine chelated calcium melon-seed-like microcapsule oral preparation, which comprises the following steps: directly carrying out water bath chelation reaction on lysine and calcined scallop shell powder to prepare lysine chelated calcium from biological calcium; the chelated calcium is embedded in the composite enteric gel micro-capsule with the special-shaped structure through the special-shaped structure generated by iron ion cross-linking carboxymethyl cellulose high-viscosity liquid drops under interfacial tension and gravity balance, and the prepared product has the characteristics of no decomposition of gastric juice and long retention time of intestinal tracts..
