準內。所以目前從油的成品來
看，確實沒有很好的檢驗方法
能判斷這個油是不是食用油，
只有在源頭上尋找原因。然而，
從外觀上區分“地溝油”和“食
用油”在某程度上是比較困難。
與此同時，至今仍沒有一種理

避免到國內飯店吃東西，盡可能
光顧信譽好、有口碑的食店，應盡量避免光顧街邊

Gutter oil: Another Shock in the Food Safety Trade
In China, around 10% of eateries use “gutter oil” by illegally processing kitchen wastes, by filtering, sedimentation, heating, distilling
and separation into a look-alike cooking oil, except for the pungent smell. Others even use rotten animal parts to process – all without
brand nor manufacturing names nor expiry dates. The main ingredient is triglyceride but plus many pathogenic and carcinogenic
poisons, especially aflatoxin, a potent carcinogen. Long-term consumption of “gutter oil” leads to subnormal development, gastro-
enteritis, liver, heart and kidney diseases. Kitchen waste decomposes, oxidizes and disintegrates into various toxic chemicals; bacteria,
fungi and other harmful micro-organisms thrive; detergent and lead cause diarrhea, tummy ache, nausea, vomiting, anemia, toxic
liver diseases, etc., let alone oxidation, hydrolysis and polymerization leading to aldehydes, ketones and lactones production at high
temperatures, not just loss of vitamins and nutrients. The trans-fatty acid and saturated fatty acid contents are high. Ban “gutter oil” that
leads to fatty livers, high cholesterol, hypertension, cholecystitis, gastritis and obesity!
魚、水煮牛肉和用大量油炸的食物，因製
作過程中需要大量食油。雖然，肉眼難分
辨“食用油”與“地溝油”，但細看的話，煎
煮呈透明狀，後者則因含雜質，透明度較
低，部分有沉澱物，或可將油滴在手半上
磨擦，是否有難聞或異味，一有懷疑，立
刻停止進食。一旦在飯店進食後出現了腹
痛、惡心、嘔吐等症狀，一定要在極短時間內到醫
院進行救治，以免對您的身體造成更大的傷害。
