Abstract:
... This study proposes a biorefinery approach system to treat two berry extrudates generated by the berry-tasted products industry. The berry extrudates studied were strawberry extrudate (SE1 and SE2) and raspberry extrudate (RE), both of them processed in the same industrial plant. The proposed biorefinery approach consists in the extraction of bioactive compounds after hydrothermal pre-treatment fo ...

Abstract:
... Consumption of raspberry (Rubus idaeus L.) has drastically increased in the last decade. However, fruit perishability, mainly due to water loss, morphological fragility, softening, and presence of pathogens like botrytis, is still the major problem limiting raspberry marketability. Therefore, high firmness and prolonged shelf life are the two key quality traits of a successful raspberry genotype. ...
