Antioxidant Properties of "Natchez" and "Triple Crown" Blackberries Using Korean Traditional Winemaking Techniques.

This research evaluated blackberries grown in Oklahoma and wines produced using a modified traditional Korean technique employing relatively oxygen-permeable earthenware fermentation vessels. The fermentation variables were temperature (21.6°C versus 26.

Simultaneous determination of phenolic compounds in Cynthiana grape (Vitis aestivalis) by high performance liquid chromatography-electrospray ionisation-mass spectrometry.

Phenolic acids, flavanols, flavonols and stilbenes (PAFFS) were isolated from whole grapes, juice, or pomace and purified using enzymatic hydrolysis. Only anthocyanin mono-glucosides and a few of the oligomers from Cynthiana grape (Vitis aestivalis) were analysed. Flavonoid-anthocyanin mono-glucosides (FA) were isolated using methanol/0.

Effects of fruit maturity on watermelon ultrastructure and intracellular lycopene distribution.

This study employed transmission electron microscopy (TEM) to conduct research on the ultrastructure of watermelon (cultivar: Hazera SW1) mesocarp samples of different maturities. Micrographs from immature fruit showed incompletely formed chromoplasts. A combination of distinct pigment-bearing chromoplasts and incompletely formed chromoplasts was observed in mature watermelon micrographs.

Effect of beta-cyclodextrin in improving the correlation between lycopene concentration and ORAC values.

Lycopene, a lipophilic antioxidant, plays a crucial role in biological systems. It may play an important role in human biological systems by providing protection against cardiovascular disease and some cancers and by boosting the immune system. The oxygen radical absorbance capacity (ORAC) has been validated as an index of antioxidant activity for many hydrophilic antioxidants but not for lycopene.
