摘要

羊乳產品日漸風行，為保障民眾消費之權益，由各縣市衛生局先進行市售羊乳製品（包括鮮羊乳、調味羊乳、羊奶粉及羊乳片等）之標示檢查計377件，再對未標示牛乳成分之288件產品中抽樣74件，由本局以中國國家標準膠體電泳方法及本局89年度建立之毛細管電泳方法分別進行檢驗，以檢出牛乳之α(下標 s1)-酪蛋白判定摻偽，其檢出靈敏度以羊乳中牛乳之含量計分別為1%及2%。
檢驗結果，74件檢體中檢出牛乳成分者共12件，檢出率16.2%，其中包括16件鮮羊乳檢出1件，檢出率6.3%，25件調味羊乳檢出2件，檢出率8.0%，25件羊奶粉檢出5件，檢出率20%，8件羊乳片檢出4件，檢出率50%。二種檢驗方法均顯示相同的檢驗結果。
羊乳產品添加牛乳成分而未標示，係違反食品衛生管理法有關標示之規定，違規產品均已函請各縣市衛生局依法處辦。本調查係本局之比較檢驗，曾於九十年十月二十六日發布新聞在案。
