乾燥穀類早餐食品中抗氧化劑之標示及含量調查

INVESTIGATION OF ANTIOXIDANT IN BREAKFAST CEREALS

西式早餐調配簡便，包裝亦較傳統早餐如豆漿，油條等看起來衛生，十分符合現代化工商業社會的要求。乾燥穀類早餐食品多與牛奶或果汁混合食用，以達到營養的需求及口味的變化，因此逐漸受到國人的歡迎。此類產品主要是以玉米、小麥、大麥、燕麥及米等穀類為原料，加工製成具有疏鬆組織的脆片、各種形狀的小塊或粉末， 因接觸空氣之表面積很大，為防止其氧化變敗及延長保存性，故製造時常須添加適量的抗氧化劑。行政院衛生署公告的“食品添加物使用範圍及用量標準＂規定，乾燥穀類早餐中抗氧化劑之使用量，BHA及BHT均0.05g/kg以下，為了解市售產品是否有不當或過量之添加而危害消費者健康，本調查乃就進口及國產各種乾燥穀類早餐食品之抗氧化劑含量及其標示情形進行調查，俾供消費大眾及衛生主管機關之參考。
