Abstract

Furfural and 5-(hydroxymethyl)-2-furaldehyde (HMF) are useful indicators of accurate storage temperature of food samples. A first derivative spectrophotometric method was developed for the determination of the furfural and HMF level in Locust bean pekmez. In addition, the levels of the furfural and HMF were investigated during Locust bean pekmez preparation. The recoveries were generally nearly 100%. This method is also rapid and accurate and results in economical analyses of furaldehydes.

摘要

糠醛和5-（羟甲基）-2-糠醛（HMF）是食品样品准确储存温度的有用指标。建立了一种一阶导数分光光度法用于测定刺槐豆胶糖浆中糠醛和HMF的含量。此外，还研究了刺槐豆胶糖浆制备过程中糠醛和HMF的含量。回收率一般接近100%。该方法快速准确，对糠醛进行经济分析。
