Because pearl powder has a whitening function, long-term use can keep skin smooth and delicate; however, as the main component of pearl powder, calcium carbonate and some other components are not easy to be absorbed by the human body. In order to overcome the above problems, researchers began to use enzymatic hydrolysis to hydrolyze pearl powder into amino acids and small peptide molecules that are easily absorbed by the human body, so that pearl powder can be fully utilized.
However, the existing enzymatic hydrolysis method is to first carry out lactic acid treatment and centrifugation treatment on pearl powder, and the insoluble part is enzymolysis and enzyme killing treatment with protease to obtain enzymolysis pearl liquid. However, this method produces liquid, which is not very convenient for storage and transportation.
The following is about the application advantages of lyophilizer in enzymatic pearl lyophilized powder. Compared with the prior art, the enzymatic hydrolysis pearl lyophilized powder is obtained by successively acidifying the pearl powder, enzymolysis and vacuum freeze-drying of the lyophilizer, so as to replace the traditional enzymatic hydrolysis pearl liquid, which is not only convenient to carry and use, but also convenient to store and save storage space.
At the same time, by strictly controlling each step in the acidification and enzymatic hydrolysis process and reasonably optimizing the specific process parameters of each step, it can not only effectively improve the overall preparation efficiency, but also improve the nitrogen content of enzymatic hydrolyzed pearl lyophilized powder. The prepared pearl lyophilized powder has the characteristics of convenient storage and transportation.
