Condensed Tannin Reacts with SO2 during Wine Aging, Yielding Flavan-3-ol Sulfonates.

open access: yesJournal of Agricultural and Food Chemistry, 2018
Numerous monomeric and oligomeric flavanol sulfonation products were observed in 10 wines. Levels of 0.85-20.06 and 0-14.72 mg/L were quantified for two monomeric sulfonated flavan-3-ols and, surprisingly, were generally higher than the well-known native

Effects of Dehulling and Extrusion‐Cooking on the Nutritional and Physicochemical Properties of Navy Bean (Phaseolus vulgaris L.) Flours

open access: yesChemFoodChem, EarlyView.
Dehulling combined with twin‐screw extrusion improves the nutritional and functional properties of steam treated navy beans. Protein digestibility increases while phytic acid is reduced by 43% and trypsin inhibitors are inactivated. Enhanced expansion, solubility, and sensory quality highlight the potential of dehulled bean flours for developing ...
