Abstract:

The dispersibility of ellagic acid was improved by emulsification, and the stability of ellagic acid aqueous solution and emulsion in different treatment temperatures, ultraviolet irradiation and partial medium solutions was studied. The results show that the stability of the ellagic acid aqueous solution gradually decreased during storage. High treatment temperature, UV irradiation, inorganic salt NaCl, carboxyl cellulose sodium and other additives are not conducive to the stability of ellagic acid aqueous solution, while glycerin, β-cyclodextrin and other additives are beneficial to the stability of ellagic acid aqueous solution. The emulsification of ellagic acid can improve the stability of ellagic acid during storage.

Key words: ellagic acid, emulsion, ultraviolet spectrophotometry, stability, protection
