The invention discloses
garlic powder of a core-shell structure and a preparation method and application thereof, and belongs to the technical field of medicines.The preparation method of the
garlic powder of the core-shell structure comprises the following steps that garlic and water are pulped, and
slurry is obtained; adding a compound
enzyme into the
slurry, and carrying out enzymolysis to obtain an enzymatic
hydrolysate; carrying out
ultrafiltration on the enzymatic
hydrolysate by using an
ultrafiltration membrane with the molecular weight
cut-off of 1000Da, and then carrying out
ultrafiltration by using an ultrafiltration membrane with the molecular weight
cut-off of 100Da, so as to obtain ultrafiltrate; performing vacuum
freeze drying on the ultrafiltrate to obtain
garlic powder; the preparation method comprises the following steps: adding
pullulan,
galactose and polycarboxylic acid into water, uniformly stirring, then adding
amylopectin,
chitosan and
maltodextrin, and uniformly stirring to obtain shell liquid; adding the garlic
powder into the shell liquid, ultrasonically stirring uniformly, and freeze-
drying in vacuum to obtain the garlic
powder with the core-shell structure. The garlic
powder with the core-shell structure has excellent stability, meanwhile, the garlic powder with the core-shell structure has a good slow-release effect, and the effect of effectively treating the non-
alcoholic steatohepatitis can be achieved.
