Application of Gas Chromatography Technology in the Quality Detection of Grain and Oil Food
In view of the problems of additive abuse,pesticide residue and harmful chemical pollution in grain and oil food safety at present,this paper takes five well-known brands of edible oils circulating in the market as examples,and carries out comprehensive quality detection and analysis by gas chromatography technology.The results show that two kinds of antioxidants and two kinds of preservatives are successfully identified by gas chromatography technology,which provided a scientific basis for the supervision of food addition.A variety of harmful pesticides are effectively identified by gas chromatography technology,to ensures the edible safety of grain and oil products.Gas chromatography has successfully distinguished and quantified the composition of various fatty acids,which provides a scientific basis for evaluating the quality and nutritional value of oils and fats.
