Surface functionalization of bioactive glasses and hydroxyapatite with polyphenols from organic red grape pomace

Bioactive Surface Modification of Hydroxyapatite

The purpose of this study was to establish an acid-etching procedure for altering the Ca/P ratio of the nanostructured surface of hydroxyapatite (HAP) by using surface chemical and morphological analyses (XPS, XRD, SEM, surface roughness, and wettability) and to evaluate the in vitro response of osteoblast-like cells (MC3T3-E1 cells) to the modified surfaces. This study utilized HAP and HAP tre...

Recovery of aromatic aglycones from grape pomace

The Effect of Red Grape Pomace Powder Replacement on Physical Characteristics and Acrylamide Content of Biscuit

Background and Objectives: Biscuit is the most popularly consumed bakery item, and due to higher consumption among children, increase of its nutritional value and safety is a necessity. Acrylamide is a potential carcinogen that is formed in carbohydrate-rich food products like biscuits at temperatures above 120oC. Among the various parameters, which affect acrylamide formation, the inhibitory e...

Colloidal Gas Aphron Extraction of Bioactive Compounds from Brazilian Pinot Noir Grape Pomace

Residues from the food industry are a problem worldwide. Alternatives have been developed in an attempted to extract compounds from fruit pomace in other to apply those as a natural component in different products. This work has the objective to produce two extracts: (1) ethanolic extract and (2) hot water extract; and characterize the chemical composition of these extracts for future applicati...

Kinetic Modelling for Flavonoid Recovery from Red Grape (Vitis vinifera) Pomace with Aqueous Lactic Acid

This study was undertaken with the aim of establishing a correlation between the extraction yield in total flavonoids from red grape pomace and the extraction temperature, using 0.5% (w/v) aqueous lactic acid as the solvent system. Extraction of flavonoids was found to obey second-order kinetics, and on such a basis, the yield in total flavonoids at saturation could be very effectively determin...
