鉴别地沟油“五诀窍” | 2011-9-30 9:42:00

 

  由于混合后的地沟油与一般的散装食用油从色泽、味道上都没有明显的区别,因此鉴别起来十分不易。中医看病讲究望闻问切,有关专家提醒广大消费者,用一些土办法也可以识别地沟油

    一看:看透明度,纯净的植物油呈透明状,在生产过程中由于混入了碱脂、蜡质、杂质等物,透明度会下降;看色泽,纯净的油为无色,在生产过程中由于油料中的色素溶于油中,油才会带色;看沉淀物,其主要成分是杂质。

    二闻:每种油都有各自独特的气昧。可以在手掌上滴一两滴油,双手合拢摩擦,发热时仔细闻其气昧。有异昧的油,说明质量有问题,有臭昧的很可能就是地沟油:若有矿物油的气味更不能买。

    三尝:用筷子取一滴油,仔细品尝其味道。口感带酸味的油是不合格产品,有焦苦味的油已发生酸败,有异味的油可能是地沟油

    四听:取油层底部的油一两滴,涂在易燃的纸片上,点燃并听其响声。燃烧正常无响声的是合格产品:燃烧不正常且发出吱吱声音的,水分超标,是不合格产品;燃烧时发出噼叭爆炸声,表明油的含水量严重超标,而且有可能是掺假产品,绝对不能购买。

    五问:问商家的进货渠道,必要时索要进货发票或查看当地食品卫生监督部门抽样检测报告。
