為了解魷魚及其製品中甲醛之天然含量，由本省主要就魚集貨地及鹹魚絲製造工廠共抽41件就魚檢體，其中包括生鮮原料10件，就魚絲半成品13件，就魚絲成品11件，乾製魷魚成品7件；另抽就魚絲調味料6件。經依據藥物食品檢驗局草擬之「食品中甲醛之檢驗方法草案」檢驗其中所含之甲醛，結果顯示10件就魚生鮮原料中甲醛均未檢出，就魚絲半成品9件有甲醛陽性反應，占69.23％，就魚絲成品10件有甲醛陽性反應，占90.9％，魷魚乾製品及調味料均未檢出；顯示關於甲醛之存在與否，就魚絲及乾製鹹魚在製造過程中有造成差異的因素存在。由於前項所述檢驗方法之最低檢出量為10ppm，故「未檢出」表示檢體中甲醛含量為0－10ppm。若將檢驗方法加以改良，檢體量由10g提高為100g，則在5件重做的生鮮原料中，5件皆有甲醛陽性反應，其含量介於0.42－2.42ppm，顯示就魚生鮮原料中可能含有微量天然存在的甲醛。
To determine the content of formaldehyde in squids and their products, the acetylacetone method was used to test 41 samples collected from major squid fishing ports and processing mills, including 10 samples of fresh squids, 13 samples of semi-finished shredded squid, 11 samples of shredded squid, 7 samples of dried squids. Six samples of additives for shredded squids were also inspected. The results revealed that formaldehyde was detected in shredded squid semi-products and products by 70% and 91%, respectively, and none in fresh squids, dried squids and additives samples. A modified method was used to repeat the testing of 5 fresh samples. The detectable level of formaldehyde was under 1ppm when the modified method was used, whereas under the original method the detectable level was 10 ppm. The formaldehyde content of these samples, ranging from 0.42 to 2.42 ppm implies that formaldehyde may exist in squids naturally. |
