A rapid analytical method for detecting fraud in peanut oil

摘要

Owing to its pleasant flavor and the presence of compounds such as resveratrol,peanut oil is one of the major edible oils in China,along with soybean oil and rapeseed oil.However,peanut oil is more expensive than the other two oils,making it prone to adulteration by unscrupulous dealers.Such dealers may mix varying proportions of cheaper oils,such as soybean oil,sunflower oil,canola oil,or palm oil into peanut oil or,worse,use cheaper oils to make fake peanut oil by adding peanut oil flavor.
