Abstract

The invention relates to the field of microcapsules and discloses an active peptide microparticle preparation and a preparation method thereof. The preparation method comprises the following steps: adding active peptides in a sodium alginate solution to obtain an active peptide and sodium alginate mixed solution, then dropwise adding into a chitosan and cross-linking agent mixed solution or a cross-linking agent solution through a microcapsule granulator to obtain active peptide microparticles and freeze-drying to obtain the active peptide microparticle preparation; a cross-linking agent is a combination of calcium chloride, barium chloride and magnesium chloride. The active peptide microparticle preparation and the preparation method thereof provided by the invention have the benefits that through the proper cross-linking agent and the proportion thereof, the active peptide microparticle preparation has better dispersity when being brewed with water with higher temperature, meanwhile better masks the odor of the active peptides and effectively solves the problems of influence of the active peptides on long-term use of a consumer and mouth feeling.

Description

technical field [0001] The invention relates to the technical field of microcapsules, in particular to an active peptide microparticle preparation and a preparation method thereof. Background technique [0002] Many active peptides extracted from automatic plants, such as oyster peptides, skipjack fish peptides, and sea cucumber peptides, have strong biological activity and are ideal functional factors for health food. However, these active peptides have a strong odor that consumers cannot bear, which seriously affects the customer experience and willingness to take it for a long time. Therefore, there is an urgent need to improve the mouthfeel of these active peptides through taste-masking technology. [0003] Adding excipients relieves bitterness by interfering with the taste buds. The method is the simplest and the cost is low, but the effect is limited, and the effect is not good for extremely bitter and easily hydrolyzed drugs. Moreover, due to differences in taste pr...
