Effects of temperature and oxygen on storage quality of Prinsepia Utilis Royle oil
Using Prinsepia Utilis Royle oil produced in Lijiang as materials,the effects of temperature and oxygen on the storage quality of Prinsepia Utilis Royle oil were analyzed according to the changes in sensory quality,acid value,and peroxide value.The results showed that the Prinsepia Utilis Royle oil sealed and stored at low temperature(4℃)had the highest sensory score,the lowest acid value and peroxide value.Low temperature delayed the increase of acid value and peroxide value,and the influence of temperature on peroxide value was significantly greater than that on acid value.Oxygen significantly accelerated the increase of acid value and peroxide value obviously.Low temperature sealed storage significantly improved the storage stability of Prinsepia Utilis Royle oil and extended its shelf life.
