4-Hydroxy-2(or 5)-ethyl-5(or 2)-methyl-3(2H)-furanone (HEMF) is representative of the Maillard reaction-derived reductones found in many foodstuffs. Influence of HEMF on iron ion-induced oxidative modification of human erythrocyte membranes and low density lipoprotein (LDL) under aerobic conditions was investigated. When human erythrocytes

Fluorescence spectra of a 4-hydroxy-2(or 5)-ethyl-5(or 2)-methyl-3(2H)-furanone (HEMF) fermentation culture broth were combined with measurable process variables for off-line and on-line process monitoring. Culture broth fluorescence in UV and visible ranges was acquired by a fiber optic LCD array spectrometer.

The formation of HEMF [2 (or 5)-ethyl-5 (or 2)-methyl-4-hydroxy-3 (2H)-furanone] by yeast was examined in an attempt to investigate its mechanism and involved factors. HEMF formation was promoted by yeast cultivation in a heat-sterilized medium which included glucose, ribose, and

We determined the anti-cataract effects and antioxidative activities of four 4-hydroxy-3(2H)-furanones. These four furanones showed similar antioxidative activities in the ferric ion reduction model. 4-Hydroxy-2,5-dimethyl-3(2H)-furanone (HDMF) and 2(or 5)-ethyl-4-hydroxy-5(or 2)-methyl-3(2H)-furanone (EHMF) exhibited a higher suppression effect on lipid peroxidation in
