Web1 jun. 2016 · Hydroxymethylfurfural (5-HMF) can be formed in sugar-containing products and has been identified as possibly carcinogenic to humans. The effect of UV-C treatment at 254 nm on 5-HMF content in high fructose corn syrup (HFCS) and model sugar solutions was studied at doses from 50–250 mJ cm −2. Hydroxymethylfurfural (HMF), also 5-(hydroxymethyl)furfural, is an organic compound formed by the dehydration of reducing sugars. It is a white low-melting solid (although commercial samples are often yellow) which is highly soluble in both water and organic solvents. The molecule consists … Meer weergeven HMF was first reported in 1875 as an intermediate in the formation of levulinic acid from sugar and sulfuric acid. This remains the classical route, with 6-carbon sugars (hexoses) such as fructose undergoing … Meer weergeven A major metabolite in humans is 5-hydroxymethyl-2-furoic acid (HMFA), also known as Sumiki's acid, which is excreted in urine. HMF bind intracellular sickle hemoglobin (HbS). Preliminary in vivo studies using transgenic … Meer weergeven HMF is an intermediate in the titration of hexoses in the Molisch's test. In the related Bial's test for pentoses, the hydroxymethylfurfural from hexoses may give a … Meer weergeven HMF is practically absent in fresh food, but it is naturally generated in sugar-containing food during heat-treatments like drying or cooking. Along with many other flavor- and color-related substances, HMF is formed in the Maillard reaction as well as during Meer weergeven Today, HPLC with UV-detection is the reference-method (e.g. DIN 10751-3).
