摘　　要：在F55果葡糖浆的生产工艺中,由于淀粉投料及中间部分工段控制温度较低,系统易染菌从而产生乙醛。本文分析了添加焦亚硫酸钠对样品溶液中乙醛、色值、SO2和pH的变化情况以及不同浓度的焦亚硫酸钠溶液对乙醛的去除效果。结果表明,添加焦亚硫酸钠溶液能明显降低样品中的乙醛含量,明显增加电导率、SO2含量,但对色值和pH影响不明显,此外样品中添加的焦亚硫酸钠溶液的浓度越高,其乙醛的去除效果越好。In the production process of F55 fructose syrup,the system is easy to infect bacteria and produce acetaldehyde due to the low control temperature of starch feeding and middle section.In this paper,the change of acetaldehyde,color value,SO2 and pH in the sample solution by adding sodium pyrosulfite and the effect of different concentration of sodium pyrosulfite solution on acetaldehyde removal were analyzed.The results show that the addition of sodium pyrosulfite solution can significantly reduce the content of acetaldehyde in the sample,significantly increase the conductivity and SO2 content,but has no obvious effect on the color value and pH value.In addition,the higher the concentration of sodium pyrosulfite solution added in the sample,the better the removal effect of acetaldehyde.
