The focus of the paper is on effectiveness a functionalization process with natural polyphenols chemically treated and bioactive Ti6Al4V alloy, grafting mechanism, redox/scavenging activity grafted biomolecules. Polyphenols (phenolic acids, flavonoids, condensed tannins) are extracted from organic red grape pomace. performed at pH = 7.4 addition calcium ions, which act as bridge between substra...

Heat-resistant strains of Byssochlamys fulva, B. nivea, and other heat-resistant fungi were isolated from vineyard soil, grapes, grape-processing lines, and waste pomace. They are known to remain in grape juice occasionally and to grow in grape juice products. Ascospores of these fungi have a D value (decimal reduction time) of about 10 min at 190 F (88 C), but in the presence of 90 muliters of...

An extract of polyphenols was obtained from organic red grape pomace, chemically analyzed, and used for functionalization two bioactive glasses porous hydroxyapatite. Functionalization is effective on hydroxyapatite the glass with higher surface reactivity a different grafting mechanism. Grafting does not inhibit redox radical scavenging activity polyphenols. The grafted make continuous layer a...

The objective of this work was to estimate the antioxidant potential of the extracts from pink shrimp residue and red grape pomaces (Merlot and Syrah varietals), evaluated according to its antioxidant activity with different analytical methods, associating these properties with the chemical composition of the extract and, as a consequence, with the extraction procedure. The shrimp residue was p...

This work deals with the manufacture of new bio-based materials for building insulation from viticulture by-products, and potato starch. Four types aggregates were used separately: grape pomace, stalks, skins, crushed stalks. The starch/aggregate mass ratio was set at 20% samples obtained characterized in terms density, thermal conductivity, compressive bending strength, sound absorption coeffi...

Pentacyclic triterpenes are secondary plant metabolites widespread in fruit peel, leaves and stem bark. In particular the lupane-, oleanane-, and ursane triterpenes display various pharmacological effects while being devoid of prominent toxicity. Therefore, these triterpenes are promising leading compounds for the development of new multi-targeting bioactive agents. Screening of 39 plant materi...

Several timbers and crop by-products were subjected to an enzymatic treatment to obtain a xylo-oligosaccharides-enriched preparation. The process was performed by means of the commercial endo-β-1,4xylanase Buzyme 2511. The enzymatic cocktail was applied onto the raw ground materials with yield up to 5.3 ± 1.0 g/L xylo-oligosaccharides for apple pomace. In order to make the materials more access...

Epidemiological and experimental studies suggest that fiber and phenolic compounds might have a protective effect on the development of colon cancer in humans. Accordingly, we assessed the chemopreventive efficacy and associated mechanisms of action of a lyophilized red grape pomace containing proanthocyanidin (PA)-rich dietary fiber [grape antioxidant dietary fiber (GADF)] on spontaneous intes...
