Rapid Test Method Verification of Adulteration of High Oleic Acid Vegetable Oil in Camellia Seed Oil
Objective:1 o verity the adulteration of high oleic vegetable oil in camellia seed oil by using GB/1 5539-2008 camellia oil purity test method.Methods:Three pure camellia oils and nine high oleic vegetable oils were used to establish an adulteration model with six adulteration gradients of 0％,10％,20％,30％,50％and 100％,and the purity test of camellia oil was used to test the model by GB/T 5539-2008 camellia oil purity test,and six scoring grades of 0～5 were assigned according to the color displayed in the results,and the test results and regularity were analyzed.Conclusion:The camellia oil purity test method is suitable for the adulteration detection of high oleic acid vegetable oil,and with the increase of adulteration concentration,the higher the score value assigned to the results,and the results show a gradient change.There were differences in the sensitivity of this method to vegetable oils,with the highest sensitivity of high-oleic rapeseed oil and the lowest sensitivity of high-oleic sunflower oil,which provided a certain reference for the adulteration of high-oleic vegetable oil in Camellia oleifera seed oil.
