A review of 5-hydroxymethylfurfural (HMF) in parenteral solutions

Fundamental and Applied Toxicology, 1984
The chemical formation, toxicity, and pharmacokinetics of 5-hydroxymethylfurfural (HMF) and certain other decomposition products found in parenteral solutions are reviewed. Heat sterilization-induced hexose decomposition to furan derivatives is promoted at low pH.

Engineering a homogeneous alloy-oxide interface derived from metal-organic frameworks for selective oxidation of 5-hydroxymethylfurfural to 2,5-furandicarboxylic acid

, 2020
The selective oxidation of 5-hydroxymethylfurfural (HMF) to 2,5-furandicarboxylic acid (FDCA) is an important biomass conversion reaction. However, the multiple intermediates of the reaction make the catalyst design challenging.

Evaluation of 5-hydroxymethylfurfural content in market milk products

Food Additives & Contaminants: Part A, 2020
5-Hydroxymethylfurfural (5-HMF) is a cyclic aldehyde formed during non-enzymatic browning reactions. In milk, it is, on the one hand, a contaminant, on the other, a quality indicator. The objective of this study was to evaluate the content and selected factors affecting the concentration of 5-HMF in cows' milk and first infant milk.

Pitfalls in the 3, 5-dinitrosalicylic acid DNS assay for the reducing sugars: Interference of furfural and 5-hydroxymethylfurfural.

International Journal of Biological Macromolecules, 2020
Transformation of renewable biomass into value-added chemicals and biofuels has evolved to be a vital field of research in recent years. Accurate estimation of reducing sugars post pretreatment of biomass has been very inconsistent.

The Formation of 5-Hydroxymethylfurfural from Hexoses

Australian Journal of Chemistry, 1963
Gas chromatography has been used to demonstrate the existence of the equilibrium; fructose, during the conversion of fructose, free from glucose, into 5-hydroxymethylfurfural under conditions of acid catalysis. The relationship of this equilibrium to subsequent stages in the conversion is discussed.

5-Hydroxymethylfurfural mediated developmental toxicity in Drosophila melanogaster

Food and Chemical Toxicology
5-hydroxymethylfurfural is a common byproduct in food. However, its effect on growth and development remains incompletely understood. This study investigated the developmental toxicity of 5-HMF to Drosophila larvae. The growth and development of Drosophila melanogaster fed with 5-50 mM 5-HMF was monitored, and its possible mechanism was explored.

Electrochemical Oxidation of 5-Hydroxymethylfurfural on Nickel Nitride/Carbon Nanosheets: Identified Pathway by in Situ Sum Frequency Generation Vibrational Spectroscopy.

Angewandte Chemie, 2019
2,5-Furandicarboxylic acid, which can replace the petroleum-based monomeric terephthalic acid to prepare renewable bio-based plastics because of its similar molecular structure, was obtained from the electrooxidation of 5-hydroxymethylfurfural (HMF) with

Zur Kinetik der Bildung von 5‐Hydroxymethylfurfural

Food / Nahrung, 1971
AbstractIn Glucoselösungen mit Molenbrüchen von 0,015‐1,000 wurde die Kinetik der Bildung von 5‐Hydroxymethylfurfural im Temperaturbereich 120 bis 200 °C untersucht. Auf Grund von Vorversuchen zeigte es sich, daß zur Bestimmung des 5‐Hydroxymethylfurfurals die vom Verfasser modifizierte WINKLERsche Methode gut anwendbar ist.
