Survey on 3-Monochloro-1,2-propandiol (3-MCPD) Contents of Soy Sauce Products during Fiscal Year 2002 in Taiwan

為了解市售醬油中3-monochloro-1,2-propandiol （3-MCPD） 含量情形，2002年由衛生署委託基隆市等18個縣市政府衛生局協助至該轄區之醬油工廠或零售店進行採樣，共計採得檢體214件，包括國產醬油188件，進口醬油26件。採得之檢體送至本局檢驗，以衛生著公告方法進行檢測，該方法以GC／MS為分析儀器，方法最低檢出限量為0.01 ppm。檢驗結果87件國產醬油未檢出，23 件進口醬油未檢出；101件國產醬油檢出3-MCPD，91件國產醬油含量範圍為0.01 ppm至1 ppm另外有10件國產醬油3-MCPD含量範圍為1.25 ppm至6.63 ppm，超過現行衛生標準1 ppm。進口醬油中僅有3件檢出3-MCPD，含量範圍0.01 ppm至0.03 ppm。分析比較2000年與2002年之結果顯示後者醬油中3-MCPD的含量有顯著的下降。不符規定檢體衛生署已通知改善並送本局複驗，結果均與規定相符。"

A survey of 3-monochloro-1,2-propandiol (3-MCPD) content in soy sauce products is reported for determining the distributions of 3-MCPD concentrations. Two hundred and fourteen samples of soy sauce products, including 188 domestic and 26 imported soy sauce products were analyzed using a GC/MS method (detection limit 0.01 ppm) that was validated and promulgated by the Department of Health to check for compliance with the government’s recommended limit of 1 ppm for 3-MCPD in 2002. Results indicated that 3- MCPD was undetectable in 87 samples of domestic soy sauce products and 23 samples of imported soy sauce products 3-MCPD. Ninty-one samples of domestic soy sauce products contained 3-MCPD at concentrations in the range of 0.01 ppm to 1 ppm while 10 samples of domestic soy sauce products were found to contain 3-MCPD at concentrations greater than 1 ppm. Only 3 samples of imported soy sauce products contained 3-MCPD at concentrations in the range of 0.01 ppm to 0.03 ppm. 3-MCPD contents of domestic soy sauce products in 2002 decreased significantly in comparison with the surveyed contents in 2000. Ten domestic soy sauce products containing 3-MCPD over the regulation limits set by the government were sampled and reanalyzed again after improvements made by the manufacturers. 3-MCPD concentrations ranged from 0.02 ppm to 0.11 ppm in 5 samples and were undetectable in 4 samples, while 1 sample was no longer produced after the survey. 為了解市售醬油中3-monochloro-1,2-propandiol （3-MCPD） 含量情形，2002年由衛生署委託基隆市等18個縣市政府衛生局協助至該轄區之醬油工廠或零售店進行採樣，共計採得檢體214件，包括國產醬油188件，進口醬油26件。採得之檢體送至本局檢驗，以衛生著公告方法進行檢測，該方法以GC／MS為分析儀器，方法最低檢出限量為0.01 ppm。檢驗結果87件國產醬油未檢出，23 件進口醬油未檢出；101件國產醬油檢出3-MCPD，91件國產醬油含量範圍為0.01 ppm至1 ppm另外有10件國產醬油3-MCPD含量範圍為1.25 ppm至6.63 ppm，超過現行衛生標準1 ppm。進口醬油中僅有3件檢出3-MCPD，含量範圍0.01 ppm至0.03 ppm。分析比較2000年與2002年之結果顯示後者醬油中3-MCPD的含量有顯著的下降。不符規定檢體衛生署已通知改善並送本局複驗，結果均與規定相符。
