抄録

Glycidol fatty acid esters (GE) have been found as impurities in a refained edible oil in Germen in 2009. German officials published the first risk assessment because GE has concern of possible exposure to glycidol which is classified as a genotoxic carcinogen. Food safety commission of Japan began risk evaluation of diacylglycerol oil (brand name: Econa cooking oil) which contained much higher content of GE than in ordinary edible oils in 2009. The commission has published the risk assessment report in March 2015. The report has showed 1) safety assessment of food contained diaclyglycerol oil and 2) about safety of GE as impurities in fats and oils. GE was a novel substance that found in food, therefore, development of quantitative qualification method was priority challenge globally. Four quantitative qualification methods used to detect GE in edible oil as well as fat processed food have been registered as AOCS official method as of 2015 end. Recently, Japanese officials has revealed research results of GE content in edible oils and fat processed foods in "risk profile sheet of GE" that was published in March 2015. The GE content in products in Japanese market were lower level than that of products reported in oversea. Current information of GE regarding the risk assessment published by Japanese officials, international development of analytical method and research result of GE content in foods have been updated in this manuscript.
