有许多地方用砂炒药的砂不仅要经过过筛、净选等方法处理,而且还要加入1～2％的食用植物油;拌炒至色泽均匀时,取出备用。这种做法在最新的高等医药院校教材中也有记载。我认为用这种方法处理的砂——“油砂”炒药有以下几方面不妥。1 对炒药工人身体健康有害,且污染了环境。加工“油砂”所加的植物油多为菜油和豆油。这些植物油本身并无致癌作用,但由于它们含有较多的不饱和脂肪酸,当油温加热列60℃时就开始氧化,升至130℃时氧
There are many places where the sand used for sand-frying medicine must not only be processed through sifting, clean selection, etc., but also add 1 to 2% of edible vegetable oil; stir-fry until the color is even, remove and reserve. This practice is also documented in the latest textbooks for higher education institutions. I think that the sand--“oil sands” fried in this way has the following problems. 1 It is harmful to the health of speculation workers and pollutes the environment. The vegetable oils added to the processing of “oil sands” are mostly vegetable oil and soybean oil. These vegetable oils are not carcinogenic by themselves, but because they contain more unsaturated fatty acids, they start to oxidize when the oil temperature is heated at 60°C, and rise to 130°C when oxygen is used.
