TOTAL PHENOLIC CONTENTS OF SOME NATURAL FRUIT JUICES AND NECTARS FROM ROMANIAN MARKET

Abstract

Total phenolic contents (TPC) of some natural  fruit juices and nectars from the Romanian market were determined immediately after opening and after three days of refrigeration (4-8⁰C). The highest TPC were revealed in aronia juice and black currant nectar (110.80 respectively 120.69 mg GAE/100 ml). The lowest TPC were registered in peach and apricot nectars (18.17 respectively 24.91 mg GAE/100 ml). After three days of refrigeration, there were significant differences in TPC for three samples:apple juice, blueberry juice and peach nectar. The natural fruit juices and nectars tested are a good source of antioxidants (especially aronia, blueberry and black currant).
