Chardonnay and Tinta Cao grape pomaces were generated by the winemaking process. The pomaces were extracted with 50% acetone and tested for antioxidant capacities using the oxygen radical absorbance capacity (ORAC) assay, 50 EC , and ABTS •+ scavenging capacity tests. Cytotoxicity and antiproliferative activities against Caco-2 and HT-29 human colon cancer cell lines were also analyzed. The qua...

Three natural deep eutectic solvents (NADES; choline chloride (CC): lactic acid (LA), CC: oxalic (OA), urea (U)) in the ratio 1:2 were tested as a pretreatment of apple pomace prior to hot water extraction pectin. The duration and temperature (for 0.5–2h, at 40–80 °C) was adjusted limit cell wall polysaccharides losses degradation. Extraction yields sugar composition used evaluate impact on pec...

Pectin oligosaccharides, which can be obtained from fruit wastes, have proven their potential as plant immune-system elicitors. Although the precise size of active species is still under investigation, medium oligosaccharides been reported most active. Three defined oligogalacturonic acid (OGAs) mixtures were produced commercial pectin, orange peel and apple pomace residues. The methodology dev...

In this study, the designed dual stage membrane bioreactor (MBR) system was conceptualized for the treatment of cyanide and heavy metals in electroplating wastewater. The design consisted of a primary treatment stage to reduce the impact of fluctuations and the secondary treatment stage to remove the residual cyanide and heavy metal contaminants in the wastewater under alkaline pH conditions. T...

Several studies have shown that UV-C (ultraviolet C) irradiation promotes the bioactive compounds and antioxidants of fresh fruits and vegetables. The aim of this study was to apply UV irradiation in dried lemon pomace powder for enhancing its phenolic content and antioxidant properties, thus more bioactive compounds should be available for extraction and utilization. Lemon pomace dried powder ...
