Abstract

The relaxation maps of three edible vegetable oils(peanut oil,sunflower seed oil and sunflower seed oil) and rice bran crude oil were detected by low-field nuclear magnetic resonance technology(NMR).An obvious characteristic peak has been determined in the relaxation maps of rice bran crude oil at 10ms,which can not be detected in the other three kinds of pure edible oil.And the area proportion increased with the increase of rice bran crude oil content.Therefore,the detecting of the characteristic peak area can judge the vegetable oil adulterated with rice bran crude oil.

Key words： NMR; T2 relaxation; adulterate; rice bran crude oil; edible oil
