Abstract
The invention relates to a method for improving oxidation resistance and / or ultraviolet resistance of tea oil and application of the method, according to the method, the acid value and the peroxide value of the tea oil are remarkably improved through lipase treatment, and the increase of the content of free fatty acid is reflected. Although, the oxidation stability of the treated tea oil is not influenced, and the tea oil treated by lipase maintains the original characteristics in the aspect of oxidation stability. DPPH and ABTS free radical scavenging ability tests show that the oxidation resistance of the tea oil treated by the lipase is remarkably improved, and the effect is particularly obvious at a relatively high concentration. In addition, the tea oil treated by lipase can significantly improve the cell survival rate. Finally, through GC / MS analysis, obvious difference of chemical components among different lipase catalyzed tea oil products is revealed, and the optimized tea oil product contains 17 unique compound components and shows an excellent cell light protection effect.
