Response surface methodology was used to optimise the combined effects of malaxation time (t) and aqueous citric acid solution (CA) added at the beginning of the malaxation step on total polyphenols (TP) and o-diphenols (OD) content and the antiradical power (ARP) of the olive oil extracted from the Italian olive fruits of Coratina cultivar....

The aim of this research was to study the recovery of phenolic compounds from grape seeds, by-products from winemaking industries, using ethanolic solid–liquid extraction. For such a purpose, the combined effects of the extraction time (9, 19 and 29 h) and the solid–liquid ratio (0.10, 0.20 and 0.30 gdwmL1), were investigated (where dw¼dry...

Response surface methodology was used to optimise the combined effects of malaxation time (t) and aqueous citric acid solution (CA) added at the beginning of the malaxation step on total polyphenols (TP) and o-diphenols (OD) content and the antiradical power (ARP) of the olive oil extracted from the Italian olive fruits of Coratina cultivar....

The adsorption of phenolic compounds from olive oil wastewater by commercial activated carbon was studied as a function of adsorbent quantity and temperature. The sorption kinetics and the equilibrium isotherms were evaluated. Under optimum conditions (8 g of activated carbon per 100 mL), the maximum sorption capacity of activated carbon...

Subcritical water extraction of phenolic compounds from grape pomace was performed. The combined effects of extraction temperature (100, 120 and 140 ◦C) and pressure (8 MPa, 11.5 MPa and 15 MPa) were investigated using a 32 full factorial design and response surface methodology. Extractions with significantly higher polyphenols, flavonoids and...

Infiltrated electrodes for intermediate temperature-solid oxide fuel cells (IT-SOFCs) are currently the subject of intense research. Focusing on electrodes with a fibrous microstructure typically obtained through the electrospinning technique, we analyze the role of infiltrations from a modelling point of view. The model includes the evaluation...

The aim of the present work was to optimise the oil extraction process of the Italian olive fruits of Coratina cultivar using a previously selected enzyme formulation.

During the last years, olive industry wastes are considered as a potential source of extracts with antioxidant properties rich in polyphenols. The recovery of these added-value compounds can be interesting both for their beneficial properties and from an environmental point of view and several studies have been performed for the optimization...

The aim of this research was to investigate the effect of the addition of digested urban sludge on the growth medium of the microalga Chlorella vulgaris. The anaerobic digestion of biomass feedstock and/or the biodegradable fraction of wastes is widely recognized as a mature and cost-effective process for producing biogas, which is a valuable...

This study focused on the use of a non-conventional extraction technology by employing high-pressure hightemperature stirred reactor to extract polyphenols from grape skins. Extraction time (15–330 min) and temperature (30–150 C) were selected as independent variables, and their effects were studied. A preliminary kinetic study on polyphenols...

Olive pomace is one of the most interesting wastes containing bioactive compounds; the extraction of polyphenols can represent an innovative solution for the reduction of the environmental hazard of this solid and the simultaneous recovery of high-added value compounds. In this study, Supercritical Assisted Atomization (SAA) was employed for...

Color, texture and taste are key elements of a consumer's buying decision; thus, monitoring the stability of these features throughout the entire period of yogurt validity is fundamental for dairy product producers. Color, texture and taste deteriorations are due to changes in the physical, chemical and microbiological compositions of yogurt...

L'obiettivo dello studio è stato l'impiego di bicarbonato di sodio come fonte alternativa di carbonio in colture di Chlorella vulgaris, usualmente realizzate con la sola CO2. La microalga è stata inoculata in beuta e fatta crescere per 15 giorni in colture batch in presenza di NaHCO3 (0.2, 0.4 e 0.8 g/L), mantenendola in sospensione mediante...

The present work deals with the development of an enzymatic treatment aiming at producing high-quality olive oil with increased phenolics content and antioxidant activity.
