The invention discloses a
vitamin K2 composite micro-
capsule system with
stomach protection and intestine slow release functions and a preparation method and application thereof, the
vitamin K2 composite micro-
capsule system with
stomach protection and intestine slow release functions comprises three
layers, namely a core layer, a middle layer and an outer layer from inside to outside in sequence; the core layer is formed by
coating vitamin K2 with a zein-lac hydrophobic core, the middle layer is a
pea protein-
pectin electrostatic compound, and the outer layer is
sodium alginate and
chitosan double-network gel. The micro-
capsule system provided by the invention can be tightly combined in a
gastric acid environment after being orally taken, the release of active ingredients in the
stomach is reduced, and then the micro-capsule system stays at
intestinal mucosa for a long time and slowly releases contents, so that the functions of the micro-capsule system are slowly presented outside, the half-life period is prolonged, and the action effect is improved.
Vitamin K2 directly or indirectly participates in and regulates various physiological processes related to health, and plays an important role in the aspects of maintaining
bone health, preventing cardiovascular diseases, protecting nerves, improving
metabolism and the like.
