浩瀚顶空气相色谱仪测定蘑菇罐头中SO2的残留量GC7990

Sulfur dioxide combustion sulfur dioxide is allowed to use one of the bleaching agent for food, etc. will be dissociated into sulfurous acid, sulfurous reductive, showing bleaching, decolorization, corrosion and antioxidant. Some businessmen is the use of these characteristics of sulfur dioxide, disposable chopsticks and other wood products with sulfur fumigation, so as to achieve anti-corrosion function of bleach. But due to improper use, so that the product of sulfur dioxide residues.
Tengzhou Xiangying Analytical Technology Co., Ltd. used headspace gas chromatography for the determination of SO2 residues in mushroom cans with satisfactory results.
硫磺燃烧生成的二氧化硫是我国允许使用的漂白剂之一,其用于食品等会解离成亚硫酸,亚硫酸有还原性,显示漂白、脱色、防腐和抗氧化作用。而一些商人就是利用二氧化硫这些特性,对一次性筷子等木制品用硫磺进行薰蒸,从而达到漂白防腐功能。但由于使用不当,使产品中二氧化硫残。
滕州市翔鹰分析技术有限公司采用顶空气相色谱法测定蘑菇罐头中SO2的残留量，结果满意。
