The digestibility and estimated glycemic indices (GI) of native (NWS), cross-linked (CLWS) and hydroxypropylated wheat starches (HPWS) were obtained by in vitro enzymatic hydrolysis. The resistant starch (RS) content and GI were found to be 6.59 and 93.13 for NWS, 7.57 and 92.20 for CLWS, and 13.15 and 89.04 for HPWS, respectively. The amounts of glucose release for CLWS were approximately 6–11...

In a previous communication (1) some of us described the isolation from wheat germ oil of an alcohol, C&Hb002, having marked vitamin E activity, for which we proposed the name a-tocopherol. The substance itself was an oil, and was isolated in the form of the allophanate melting at 158-160’ from which it could be easily regenerated by alkaline hydrolysis. From it was also obtained a p-nitropheny...

Effects of alkaline hydrogen peroxide (AHP) treatment on cellulose crystallinity and cell wall phenolic monomer and monosaccharide composition were measured using cotton and wheat straw (WS). Two WS treatments were used in this study, Type I WS, for which pH is not regulated during AHP treatment, and Type II WS, for which pH is regulated at 11.5 -+ .2 during AHP treatment. Wheat straw had a low...

The enrichment of oils with nutraceutical bioactive phytomolecules allows the achievement functional oil-based products great interest in food, pharmaceutical, and cosmetic fields. Carotenoids, such as lycopene ?-carotene, are available at a high concentration tomatoes tomato waste products, peels, seeds, pulp; their recovery is recently attracting growing economic importance food industry, als...

in this study, the growth of two strains pseudomonas fluorescens vupf5 and p. fluorescens vupf5-1 (mutant bacterium similar to mutants of regulatory gacs/gaca system) were evaluated in the organic media. this spontaneous mutation blocked biosynthesis of the antimicrobial compounds hydrogen cyanide, phenazine and exoprotease by biocontrol strain pseudomonas fluorescens vupf5. by using organic me...

Three types of nuruk were made from rice, wheat, and a rice-glasswort (6:4) mixture. Nuruk, makgeolli, and vinegar were manufactured with rice nuruk (RN), wheat nuruk (WN), and rice-glasswort nuruk (RGN). The saccharifying activity and ethanol productivity of nuruk, polyphenol content in makgeolli, and acetic acid and polyphenol content in the vinegar were increased as the result of the additio...

Ever since Pasteur's work (1876) it has generally been believed that without oxygen yeast can either grow only to a limited extent, or not at all (Brown, , O j ; Windisch, '32 ; White and Munns, 51). The slight growth that was obtained occasionally under anaerobiosis was attributed to the traces of oxygen left in the medium. The careful work of Stier and his collaborators (Stier, Scalf and Broc...
