Carvacrol slow release preservative and preparation method thereof

Abstract

The invention belongs to the field of food processing preservation technology and particularly relates to carvacrol slow release preservative which is prepared from Beta-cyclodextrin and carvacrol in a clathration manner, wherein the mass ratio of the Beta-cyclodextrin to the carvacrol is (7:1)-(10:1). The invention further provides a preparation method of the carvacrol slow release preservative. The carvacrol slow release preservative, provided by the invention, is safe and environmentally friendly, can prolong the refreshing time of berries by more than 30% compared with a common low-temperature storage method, and effectively solves the problems that carvacrol liquid is inconvenient to use, and has greater smell and short action time during the storage process of berries. The preparation method is simple and easy to operate.
