Abstract This study had as a goal to carry out the drying of red grape pomace (RGP) using 2 × 3 factorial design. The design experiment included combinations time and temperature in order achieve lowest possible moisture levels examine losses precious polyphenols, but also effect on antioxidant properties RGP extracts. Drying for 6 hrs at 80°C (D6/80) provided with satisfactory level (11%). A c...

Pecan shells are a rich source of various bioactive compounds with potential antioxidant and antimicrobial properties. This study investigated the effect pecan variety method extraction on property shell extracts. Twenty different varieties were subjected to either aqueous or ethanolic examined for total phenolics antiradical activity. The phenolic content activity extracts significantly (p &lt...

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 explo...

Cistus incanus (Cistaceae) is a Mediterranean evergreen shrub. Cistus incanus herbal teas have been used as a general remedy in traditional medicine since ancient times. Recent studies on the antioxidant properties of its aqueous extracts have indicated polyphenols to be the most active compounds. However, a whole chemical characterisation of polyphenolic compounds in leaves of Cistus incanus (...
