Chemical composition and bioactivity of oilseed cake extracts obtained by subcritical and modified subcritical water

Abstract Recovery of bioactive compounds from biowaste is gaining more and interest in circular economy models. The oilseed cakes are usually insufficiently exploited by most technologies since they represent valuable matrices abundant proteins, minerals, phytochemicals, but their use mostly limited to feed ingredients, fertilizers or biofuel production. This study was thus focused on the exploration new valorization pathways subcritical water, representing a safe economic alternative creation value chains. Pumpkin, hemp, flax seed were treated with water nitrogen carbon-dioxide atmospheres, as well atmosphere addition acid catalyst. degradation carbohydrate fraction studied quantifying sugars sugar products obtained extracts. extracts under different conditions further compared chemically respect total phenols flavonoids, content individual phenolic compounds. Furthermore, effects treatment antioxidant, antiradical cytotoxic properties defined discussed. Graphical
