现在的消费者购买食用油一般都到超市大卖场。由于大桶包装的油价格便宜,有的三口之家一下子买5升,吃上几个月,因为保质期长达1年,所以觉得这样没问题。
Now consumers buy Edible oil are generally to the supermarket. Because the barrel packaging of cheap oil, some three homes to buy all of a sudden 5 liters, eat a few months, because the shelf life of up to 1 years, so think it no problem.
  其实,许多人对保质期都有误解:保质期1年指的是密封条件下可保存1年,一旦打开油桶盖,油与空气接触,在夏天,只需1个月油就开始氧化变质;就算不打开盖,由于塑料油桶的阻隔性较差,阳光和氧气易透入,时间一长,油的质量也会渐渐变差。常可看到有些优质的食用油用绿色的玻璃瓶装,就是为了保证油的质量,因为紫外线、紫色和蓝色光能加速油脂氧化,而绿色和棕色光则不会。
In fact, many people have misconceptions about the shelf life: 1 year shelf life refers to the sealing conditions can be preserved for 1 years, once open oil tank cover, oil and air contact, in the summer, only 1 months of oil began to oxidation; if not open the cover, because the plastic barrel barrier of the poor, the sun and oxygen easy penetration, for a long time, the quality of the oil will gradually become worse. Often can see green glass bottles with some high-quality edible oil, is to guarantee the quality of the oil, because the ultraviolet, violet and blue light accelerated lipid oxidation, while green and Brown is not.
  还有一个问题被很多人忽视了:如果油桶含有塑化剂,会迁移到油中,时间越长,温度越高,迁移到油里的塑化剂量越多。因此,购买食用油还是买小瓶或小桶包装的,好在1个月内吃完。
There is a problem neglected many people: if the drums containing plasticizer, migrated to the oil, the longer, the higher the temperature, the migration to the plasticizing dose more oil in the. Therefore, the purchase of edible oil or buy a vial or keg packaging, the best finish in 1 months.
  独立包装的还是散装的

  目前,国内食用油消费仍以散装食用油为主,尤其在广大农村地区以及城乡结合部,散装食用油还很有市场。由于价格便宜,有些城市消费者也会购买散装食用油。其实,散装食用油安全风险很大。国家质量监督检验总局对食用油进行的质量检查发现:散装食用油的质量明显差于独立包装的食用油,而且所有不合格产品均为散装食用油。
At present, the domestic edible oil consumption is still the bulk edible oil, especially in the vast rural area and the urban fringe, bulk edible oil also has the market very much. Because the price is cheap, some urban consumers will buy in bulk edible oil. In fact, the bulk edible oil safety risk is very big. National Quality Supervision and inspection conducted by the General Administration of quality inspection of edible oil discovery: the quality of edible oil in bulk significantly worse on independent packing edible oil, and all the unqualified products are bulk edible oil.
  散装油在销售过程中,质量控制难以保证。少数散装食用油经营者利用食用油标准不全、市场管理不严这些弊端,暗自把质量不等、产地不同、生产时间不同的散装油混装,或把质量等级较低的食用油作为散装油出厂,人为地造成散装油质量下降。
The bulk of the oil in the sales process, it is difficult to guarantee the quality control. Oil operators using edible oil standard is not complete, the market management is not strict these drawbacks of edible a few bulk, secretly take quality range, of different origin, different production times bulk oil mixed, or the quality of lower grade edible oil as a bulk oil factory, factitious ground is caused decreased bulk oil quality.
