The dominant volatile off-flavor compounds of pea and soy milk were investigated by gas chromatography-olfactometry-mass spectrometry (GC-O-MS), sensory evaluation, and odor-activity values (OAVs), which led to the identification of their differences. We identified 11 aroma compounds as important odorants with

Elemental sulfur is a fungicide traditionally used to control Powdery Mildew in the production of grapes. The presence of sulfur residues in grape juice has been associated with increased production of hydrogen sulfide during fermentation, which could take part in

The polyhydroxyalkanes 1,6,11,16-hexadecanetetraol (1) and 2,7,12,17-octadecanetetraol (2) were synthesized utilizing the thiophene ring as a scaffold to affix the hydroxyalkyl chains by lithiation of the acidic alpha-hydrogens and subsequent desulfurization. Both compounds exhibited significant anesthetic potency, individually and in additivity

An Escherichia coli strain was engineered to synthesize 1-hexanol from glucose by extending the coenzyme A (CoA)-dependent 1-butanol synthesis reaction sequence catalyzed by exogenous enzymes. The C4-acyl-CoA intermediates were first synthesized via acetyl-CoA acetyltransferase (AtoB), 3-hydroxybutyryl-CoA dehydrogenase (Hbd), crotonase (Crt)
In the present work a new, simple, rapid and environmentally friendly dispersive liquid-liquid microextraction (DLLME) method has been developed for extraction/preconcentration of some triazole pesticides in aqueous samples and in grape juice. The extract was analyzed with gas chromatography-flame ionization
