Reseanh on Prolonging the Storage Period and Maintain Better Quality of Flax Oil with Apple Polyphenols
The effect of apple polyphenols on the storage of flax oil and the antibacterial activity of flax oil in vitro were studied.Flax oil was stored at 10,4,0 ℃ respectively.At the same time,another polyphenol treatment group was set up with 7 bot-tles in each group.The oil samples were stored in the cold storage.The acid value,peroxide value and antibacterial activity of flax oil were measured in 3 random samples every 3 months.The results showed that during storage(10,4,0 ℃),the acid value and peroxide value of flax oil increased with time,the acid value and peroxide value of flax oil in each polyphenol treat-ment group were lower at each time point compared to control groups.In vitro antibacterial test,all groups of flax oil showed certain antibacterial activity,the lower the storage temperature,the stronger the antibacterial activity of flax oil.Moreover,the antibacterial activity of flax oil treated with polyphenol was stronger than that of the control group.These results indicated that apple polyphenols could effectively prolong the storage period of flax oil and maintain the quality of flax oil.
