Valorization and Storage Stability Assessment of Underutilized Fruit Carambola (Averrhoa carambola) in Bangladesh

摘要

An effort was made to develop value added products from underutilized fruit Carambola (Averrhoa carambola) to assess its prospect in marketability and evaluated the storage stability of quality attributes at 25-34°C, 10°C and 0°C storage temperatures for 6 months. Carambola Jam showed 70.43±0.02% Carbohydrate, 1.14±0.04% Fiber, 0.47±0.01% Ash, 2.45 pH, 68.40±0.02% TSS, 0.015 mg/100 g Vitamin-C, energy 284.87±0.2 Kcal and in Squash 42.04±0.01% Carbohydrate, 0.08±0.01% Fiber, 0.39±0.04% Ash, 2.40±0.14 pH, 40.70±0.03% TSS, 0.012±0.01 mg/100 g Vitamin-C, 170.04±0.08 Kcal energy. Storage studies showed Carambola Jam and Squash can store almost without any change for 3 months. With increasing the time in 6 months of storage TSS and acidity increases, on the other hand moisture content, pH and vitamin-C decreases. Vitamin-C retention is higher at 25-34°C.
