摘要:

使用乳化法提高了鞣花酸的分散性,并研究了鞣花酸水溶液和乳液在不同处理温度、紫外光照射及部分介质溶液中的稳定性。结果表明,鞣花酸水溶液在存放过程中稳定性逐渐下降,高的处理温度、紫外光照射及无机盐NaCl、羧基纤维素纳等添加剂均不利于鞣花酸水溶液的稳定性,甘油、β-环糊精等添加剂则有利于提高鞣花酸水溶液的稳定性,鞣花酸经过乳化后可提高鞣花酸在存放过程中的稳定性。

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
