Abstract
Fermented beverages from blood fruit (Haematocarpus validus Bakh.f.exForman) and aonla (Emblica officinalis Gaertn.) were prepared to find out the interactive effect between blending of different proportion of blood fruit and aonla along with two types of organic sugar (palm and cane sugar) to add the diversity to the drinks, preserve the nutrition, antioxidative and functional properties of the fruits and reduced the post harvest losses. The beverages have the following proximate compositions viz. a significantly highest TSS (8.36 °Brix), total sugar (2.29%), reducing sugar (1.92%), alcohol (9.02%) were recorded treatment combinations T(3)S(1) (Blood fruit 90% + aonla 10% +palm sugar 20%). T(2) (100% aonla) recorded highest β-carotene (172.95 IU), titratable acidity (0.61%) and ascorbic acid (61.95 mg/100ml) while highest anthocyanin (12.98 mg/100 ml) were recorded in T(1) (100% blood fruit). Similarly, the sensory evaluation shows that most of treatments (T(1)S(1), T(3)S(1), T(3)S(2), and T(4)S(2)) were accepted by the panellists. Considering the findings of investigation and highest net monitory returns (5.84 B: C ratio) obtained, it can be conclude that blending of blood fruit and aonla at different proportion with different types of sugar has a good prospect for commercialization.
