摘要
以石河子部分地区居民常食用的不同品牌、不同渠道购买的葵花籽油为样品,测定分析其反式脂肪酸的含量及品质,比较全精炼加工食用油与"原生态"作坊式加工食用油的反式脂肪酸含量及品质的不同。结果显示:在26个被检测产品中有7个食用油产品总反式脂肪酸的含量在1%以上,1个在2%以上,多数为全精炼油产品,过度加工带来了反式脂肪酸含量的升高。该地区的作坊式压榨制油加工程度低,品质偏低;高级精炼油加工程度高,品质较高。23.1%的产品酸值和42.3%的产品过氧化值指标不符合国家标准。抽样的产品不合格率为76.9%,经常购买散装油的居民需要注意食用油品质和卫生安全等方面的问题。
The trans fatty acids content and quality of sunflower oil bought from market was determined and compared with the oil from individual workshop. The results showed that total content of trans fatty acids of 7 samples,out of the total 26 samples,were above 1%,1 above 2%,and most of them were fully refined oil,which indicated that excessive processing brought the rise of trans fatty acids content.The oil from individual workshop expressed with low degree processing,quality was lower than advanced refined oil with high degree processing. The acid value of 23. 1 % samples and peroxide value of42. 3 % samples were not in conformity with the national standards. The failure rate of the sample was76. 9 %,The inhabitants who often buy oil in bulk need to pay attention to the quality,safety and health of the oil.
