新聞辭典/順丁烯二酸
May 27th 2013, 00:41

許多食物加熱後,都會產生順丁烯二酸(Maleic acid);順丁烯二酸酐(Maleic anhydride),則是一種化學物質,又名馬來酸酐或去水蘋果酸酐,常簡稱順酐,加水就會變成順丁烯二酸。

目前美國及歐盟核准順丁烯二酸酐為合法的間接食品添加物,它可微量存在於蘋果酸或反丁烯二酸等合法的食品添加物中。不過,在國內食品衛生法規中,不允許用於食品,卻有不肖業者私自使用未核准的順丁烯二酸酐化製澱粉,以增加產品的Q彈口感。

根據科學文獻資料指出,順丁烯二酸的急毒性低,對人類不具有生殖發育、基因等毒性,亦無致癌性。依據歐盟評估資料,成人每公斤體重每天可耐受量為零點五毫克,若以六十公斤的成人計算,則可忍受劑量為每日三十毫克。
