Hydroxymethylfurfural (HMF) Test Strips, reflectometric

Method: reflectometric with test strips 1.0 - 60.0 mg/l Reflectoquant^®

The freshness of honey is determined by measuring its hydroxymethylfurfural (HMF) content. HMF is an organic compound that arises from the dehydration of fructose, e.g. when honey is heated for easier filling. HMF is barely detectable in freshly centrifuged honey, but increases at 2-3 mg/kg annually, depending on storage temperature and pH. At 21°C, HMF content can rise to 20 mg/kg in just one year. The Reflectoquant® Hydroxymethylfurfural (HMF) Test is a screening method designed to rapidly indicate whether honey samples have undergone heating during processing. It detects hydroxymethylfurfural (HMF), which forms in honey upon heating, and provides a quick assessment of heat exposure. The test is intended for screening and in-process control, helping to identify samples that may require further investigation.. Easy-to-use, portable and economical, the test is ideal for monitoring raw materials, as well as manufacturing and filling processes. This test provides a simple on-site alternative to time consuming HPLC analysis. On the test strip, HMF reacts with a barbituric acid derivative and an aminophenazone derivative to form a red-violet compound that is determined reflectometrically on the RQflex^® 20.
