Indian goose berry fortified, anti-oxidant rich bael (Aegle marmelos) fermented beverage

Bael (Aegle marmelos Correa), an important fruit of Indian subtropics, traditionally utilized in the preparation of preserve, candy, squash, RTS, etc. has immense therapeutic potential. An attempt was made to develop a bael based low alcoholic sweet fermented beverage ( may be called as bael cider), anti-oxidant fortified with 0.25 per cent bael leaf or 10 per cent Indian goose berry (Emblica officinalis Gaertn.) juice in separate batches. Unfortified bael pulp based drink was kept as control. The ameliorated pulp was fermented at 30 ± 2ºC using Saccharomyces cerevisiae. The gooseberry blended bael fermented beverage had higher anti-oxidant content in the form of phenolics (323 mg/100 ml) than leaf extract added fermented beverage (265 mg/100 ml) and control (266 mg/100 ml). Sensory evaluation of product revealed that gooseberry blended fermented beverage scored higher (8.2/10) than bael leaf blended fermented beverage (7.9/10) and control (7.0/10). Twelve months maturation study of beverage revealed increase in reducing sugars and decrease in phenolic content in all the treatments. Bael fermented beverage with gooseberry blend retained highest phenolic content (257 mg/100 ml) and sensory score 7.8/10. The study inferred that an acceptable quality fermented drink could be prepared from bael-gooseberry blend, which could be stored for one year with higher antioxidant value and minimum deterioration in the quality.
