5-Hydroxymethylfurfural (5-HMF) is known as an indicator of quality deterioration in a wide range of foods. The current study covered 70 samples taken from domestically produced foods and drinks available on the Iranian markets (including honey, jam, fruit cakes tomato paste, ketchup, syrup, fruit juice, canned fruit, UHT milk, instant coffee and jelly powder). HMF levels were determined using ...

Abstract The Maillard reaction products (MRPs) 3-deoxyglucosone (3-DG) and 5-hydroxymethylfurfural (HMF), which are formed during the thermal processing storage of food, come into contact with technologically used yeasts fermentation beer wine. In order for yeast cells to work efficiently, handling stress-inducing carbonyl compounds is essential. present study, utilization 3-DG HMF by 13 Saccha...

Aim—To evaluate the eVect of fortification on the osmolality of human milk. Methods—The osmolality of 47 samples of human milk was determined at baseline, just after, and 24 hours after supplementation with five diVerent human milk fortifiers (HMF) at 4°C. Results—Ten minutes after HMF supplementation the osmolality of human milk was significantly higher than the sum of the respective values of...

Voyager 1 continues to measure the very distant Heliospheric Magnetic Field (HMF) beyond 95 AU at ~35 North latitude. The MAG instrument data covers more than a full 22 years solar magnetic cycle. The magnitude of the observed HMF is well described, on average, by Parker's Archimedean spiral structure if due account is made for time variations of the source field strength and solar wind velocit...

The superconducting magnet generates a field and field gradient product that can levitate diamagnetic materials. In this study a specially designed superconducting magnet with a large gradient high magnetic field (LG-HMF), which can provide three apparent gravity levels (μ-g, 1-g, and 2-g), was used to simulate a space-like gravity environment. The effects of LG-HMF on the ultrastructure and fu...

BACKGROUND It is unclear how high-protein (HP) and high-monounsaturated fat (HMF) meals affect postprandial blood lipids and lipoprotein particle numbers (LPN). PURPOSE To compare a HP versus a HMF meal on postprandial lipid and LPN responses. METHODS Twenty-four participants (age: 36.3±15.0 years; body mass index: 23.6±2.0 kg/m2; 45.8% female) were fed a HP (31.9% energy from protein) and ...

A simple and efficient biphasic system comprising H2O, tetrahydrofuran (THF), cyclohexane (CHX) Al2(SO4)3 was employed to convert cellulose into 5-hydroxymethylfurfural (HMF). The volume ratio of the organic phase aqueous (Vorg/Vaque), concentration in (C[Al2(SO4)3]aque) (C[Al2(SO4)3]org) played critical roles conversion HMF. In systems with H2O/THF/Al2(SO4)3 4/18/0.4 H2O/THF/CHX/Al2(SO4)3 3/16...

A convenient and cost-efficient method featuring the integration of enzymatic and acid catalysis has been developed for the selective conversion of glucose into HMF, which provides a new strategy for HMF production from glucose.

5-Hydroxymethylfurfural (HMF) and furfuryl alcohol (FFA) are present in numerous foodstuffs at high levels. FFA is also used for the production of polymers. Both compounds had demonstrated some evidence of carcinogenic activity in 2-year bioassays. We tested these compounds and four congeners for mutagenicity in Salmonella typhimurium TA100 and TA100-derived strains expressing human or rodent s...

Citrus fruits contain various types of flavonoids with powerful anti-aging and photoprotective effects on the skin, and have thus been attracting attention as potential, efficacious skincare agents. Here, we aimed to investigate the chemical composition of Citrus unshiu and its protective effects on photoaging. We isolated and identified a bioactive compound, 3,5,6,7,8,3',4'-heptamethoxyflavone...
