Research Progress in Detection Technology of Chloropropanol Fatty Acid Esters and Glycidol Fatty Acid Esters in Food
Chloropropanol fatty acid esters(MCPDEs)and glycidol fatty acid esters(GEs)are not toxic,but their hydrolysates have been proved to be potentially harmful to human health.The latest research shows that the toxicity of 3-chloro-1,2-propanediol fatty acid(3-MCPD)mainly acts on kidney,liver and reproductive organs.At present,MCPDEs and GEs have been found in a variety of foods,including vegetable oil,bread,biscuits and infant formula,etc.MCPDEs and GEs are mainly produced in the refining process of edible oil,which belong to heat-induced processing contaminants.There are no provisions on limits for these two kinds of contaminants in foods in China.The exposure of these two kinds of contaminants in food is reviewed in this paper,and the provisions on their limits of main countries(regions)are summarized.The research progress of detection methods for these two kinds of contaminants in domestic and abroad in recent years is also introduced,in order to provide reference for safety supervision by regulatory authorities and technical development of testing institutions.
