地沟油的检测问题一直倍受大众关注,不过权威部门都表示还没有找到通用的检测方法,可有人竟声称用大蒜头能检测出地沟油,因为蒜头对地沟油中的黄曲霉素很敏感,只要在炒菜的时候放一颗剥了皮的蒜头,如果蒜头是白的,说明食用油没问题;如果蒜头变红,就说明炒菜用的油是地沟油……这个方法真的可以检测出地沟油吗?答案当然是否定的。 Detection of waste oil has been much public concern, but the authorities have said they have not found a common detection method, some people actually claimed to use garlic head can detect waste oil, garlic because of waste oil in the aflatoxin sensitive , As long as the time in the cooking put a peeled garlic, garlic is white, indicating no problem with cooking oil; if the garlic turns red, it shows cooking oil is cooking oil ...... This method can really detect Trench oil? The answer is of course no.
