Production of antioxidant enriched cranberry juice by electrodialysis with filtration membrane : impact of process on juice composition
نویسندگان
چکیده
Cranberry juice is recognized for its nutraceutical properties. Recently, it was demonstrated that it is possible to enrich a cranberry juice in antioxidants from another cranberry juice by an electrodialysis with filtration membrane (EDFM) process. In order to transpose this technology on an industrial scale for the production of an antioxidant enriched cranberry juice, the present work aimed to study, during consecutive EDFM treatments, the evolution of raw and enriched cranberry juices composition. The anthocyanin concentrations and the antioxidant capacity of the enriched juice increased respectively of 19.41% and 23.74%, while the anthocyanin concentrations and antioxidant capacity of the raw juice remained constant throughout treatments.

Electrodialysis with monopolar ion exchange membranes was used to reduce the acid content of pineapple juice. It is an electrochemical membrane separation process in which electrically charged membranes and an electrical potential difference are used to separate ionic species in the pineapple juice from other uncharged components. Several physico-chemical (pH, titratable acidity and soluble sol...

Antioxidants prevent the oxidation of low-density lipoproteins (LDL) that contributes to cardiovascular disease. While cranberries have been shown to contain antioxidants, cranberries from different sources may possess different antioxidant capacities. The purpose of this study was to determine if antioxidant capacity varies among select cranberry cultivars. Eight U.S. cranberry cultivars were ...

Background and Objectives: Pomegranate juice is prone to turbidity, which makes it hard to preserve and concentrate. Microfiltration is one of the membrane processes that can be used to reduce its turbidity, but, it is prone to membrane fouling. Pretreatment is considered the most effective way to reduce membrane fouling. Materials and Methods: This study simulated the effect of centrifugation...
