Physio-chemical characterization of juice and dried pulp from three indigenous strawberry (Fragaria × ananassa) Varieties

Abstract

The main aim of this study was to investigate the physical and physio-chemical characteristics of different strawberry cultivars. Camarosa, Chandler and Sweet Charlie were selected to evaluate physio-chemical composition of juice and dried pulp. For most of the physical characters, Camarosa has the highest fruit weight (69.1 g), maximum berry length (115.1 mm), highest berry breadth (86.5 mm) and highest juice content (52.2%) followed by chandler. For physio-chemical characters, Camarosa recorded the maximum total sugars (19.7%), reducing sugar (10.3%), and non-reducing sugar (10.4%). The maximum ascorbic acid content in juice, Sun dried pulp and oven dried pulp was recorded in camarosa (220.9 mg/100g), (222.7 mg/100 g) and (217.2 mg/100 g) respectively, while minimum was recorded in Chandler. Carotenoid content in juice, sun dried pulp and oven dried pulp was recorded maximum in Camarosa (6.2 µg/100 g), (5.4 µg/100 g), (5.8 µg/100 g) respectively. The maximum phenolic content and anthocyanin juice, Sun dried pulp and oven dried pulp was recorded maximum in Camarosa cultivar and the flavonoid content juice, Sun dried pulp and oven dried pulp was recorded maximum in Sweet Charlie (97.1 mg/100 g), (94.7 mg/100 g) and (100.5 mg/100 g) respectively. It is concluded that the Camarosa was superior to Chandler and Sweet Charlie in most of characteristics. The Camarosa has more antioxidant potential, which influences the nutritional value of fruits.
