Method for preparing organic calcium with eggshells

Abstract

The invention discloses a method for preparing organic calcium with eggshells. The method includes the steps of 1), breaking; 2), performing enzymolysis; 3), fermenting; 4), extracting; 5), packaging. The method for preparing the organic calcium with the eggshells is simple and efficient, large-scale production can be performed, extraction rate reaches 86.36%, content of calcium lactate is 93.62%, calcium gluconate is 5.46%, and revenue is increased by 15.6%. Residue protein can be decomposed by directly adding protease into the broken eggshells, and impurities in an eggshell solution can be reduced; the eggshell solution subjected to enzymolysis is fermented via lactic acid bacteria, macromolecular impurities are decomposed, lactic acid is produced, calcium ions in the calcium carbonate is separated out, and formation of the calcium lactate is facilitated; the solution is subjected to secondary crystallization to separate out organic calcium crystals, and extract rate of the organic calcium is increased; the abandoned eggshells are fully utilized and made profitable, low cost is achieved, cost is saved, poisonous reagents are not used during the preparation, residues of the reagent cannot be caused, and the method is healty and environment friendly.

AI Technical Summary

Benefits of technology

This patented technology allows for easy-to-produce organocalcium with improved purity compared to existing methods that require complicated steps or expensive materials. It involves extracting it through an aqueous phase containing water soluble calcium salt (CaCl2) dissolved therein without damaging any other components like albumen). By adding protetronic acids before grinding off the shells, excessive amounts of calciuminous chloride may also get mixed together during processing. After this treatment, the resulting liquor has higher levels of free lime permeability than previously possible due to its composition. Additionally, the extracted material includes smaller quantities of calciumen trihydroxypropylheptanoidone diphosphatite) while still being effective at promoting intestinal uptake of nutrients such as phytonutritional agents. Overall, these technical results lead to more pure and useful organochelctrochemistry products made up entirely from recovered egg shards.

Problems solved by technology

This patented technical problem addressed by this patents relates to finding an improved way to make better use of existing sources like eggs or other animal products that contain valuable mineral resources (such as calciium).
