Halogenated curcumin derivative, preparation method therefor, and application thereof in preservation of aquatic products

Abstract

The present invention relates to the field of aquatic product processing and storage; to solve the problems in that a photosensitizer generates low active oxygen during photodynamic sterilization and that the preservation effect of aquatic products needs to be improved, a halogenated curcumin derivative, a preparation method therefor, and an application thereof in the preservation of the aquatic product are disclosed. The halogenated curcumin derivative contains mono-substituted or bi-substituted halogenated groups; the halogenated curcumin derivative can be prepared by a one-step method and used for photodynamic sterilization of aquatic products. The preparation steps of the present invention are simple, the reaction conditions are mild, and the prepared halogenated curcumin derivative has high singlet oxygen yield under blue light irradiation. The present invention has good sterilization and preservation effects on aquatic products, can effectively prolong the shelf life of fresh shrimp, and has little impact on the sensory properties of the food.
