从2006年10月1日开始,我国施行了新食品油国家标准。该标准将食品油分为了四级,即一级、二级、三级和四级,共涉及花生油、大豆油、葵花油等8种常用食品油。分级以食品油的加工工艺以及精炼程度为划分标准,其中一级油的精炼程度最高,看上去更清澈透亮,因而等级最高,四级油则属于最差等级。 From October 1, 2006 onwards, China implemented the new national standards for food oil. The standard will be divided into four food oils, namely, one, two, three and four, involving a total of eight kinds of peanut oil, soybean oil, sunflower oil and other commonly used food oil. Grading According to the processing technology of food oil and the degree of refining as the standard, one of the highest levels of oil refining, looks more clear and transparent, and thus the highest level, the fourth grade oil is the worst grade.
