Optimizing germination and cultivation of edible halophytes using effluents from an IMTA system

Journal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND Halophytes offer nature‐based solutions to food insecurity and soil degradation, while their integration into integrated multi‐trophic aquaculture (IMTA) systems promotes circular economy practices. This study aimed to optimize the germination and cultivation of edible halophytic species, namely Limbarda crithmoides, Suaeda vera and

Composition and functionalities of peanut protein concentrates using ethanol as a defatted solvent and a precipitating agent

Journal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND Defatted solids (DSs) from vegetable oil extraction represent valuable feedstocks for producing protein concentrates with tailored functional properties. In the present study, using peanut protein concentrates obtained from press cakes defatted with ethanol (DSEt) or hexane (DSHx), we aimed to evaluate ethanol as a green solvent for
