Recovery of Value-Added Compounds from Winery Wastewater: A Review and Bibliome...
Santos, João R. F.; Rodrigues, Rafaela P.; Quina, Margarida J.; Gando-Ferreira, Licínio M.Value-Added Compounds (VACs) are molecules that have attracted great attention in the literature regarding their potential for integration into existing processes or products. In Winery Wastewater (WW), VACs are valuable because of their antioxidant characteristics. Furthermore, integrated systems for recovery of these molecules and treatment of WW can be a powerful strategy towards an environmentally efficient...
Grape Pomace as a Natural Source of Phenolic Compounds: Solvent Screening and E...
Rodrigues, Rafaela P.; Sousa, Ana M.; Gando-Ferreira, Licínio M.; Quina, Margarida J.The optimization of extraction by using solvents of phenolic compounds (TPh) of grape pomace (GP) based on a central composite design was investigated. The GP was characterized, and preliminary assays were conducted with five different solvents (water, ethanol, acetone, methanol, and butanol) and the aqueous mixtures thereof. Ethanol and acetone were revealed to be the best solvents for TPh extraction. The main...
Bioenergy Production through Mono and Co-Digestion of Tomato Residues
Almeida, Patrícia V.; Rodrigues, Rafaela P.; Teixeira, Leonor M.; Santos, Andreia F.; Martins, Rui C.; Quina, Margarida J.The agro-industry of tomato generates three types of residues: ripe rotten tomato (unfit for consumption) (RT), green (unripe) tomato (GT), and tomato branches including leaves and stems (TB). These materials are commonly wasted or used as feed for livestock. Energy production through anaerobic digestion is an alternative way to manage and simultaneously valorise these materials. Initially, the operating condit...
