Abstract

Quality Evaluation of Herbal Juice Developed from Traditional Indian Medicinal Plants Using Citrus limetta as Base

Harsha H and Aarti S

Lime juice, basil extract, ginger and sugar syrup were optimized and blended to form a herbal juice which was pasteurized at 90°C for 25 sec cooled and stored at refrigerated temperature 5°C for 20 days. Physic-chemical and sensory analysis was done. Marginal changes in pH, total soluble solids, acidity, vitamin C and antioxidant content were observed. The TSS increased during the storage period and was reported to be increased by 2.5°Brix. Addition of basil extract and ginger to lime juice greatly increased the antioxidant potential of the juice and also Vitamin C. Vitamin C and pH and subsequently decreased as the storage time increased. Ascorbic acid content was reported to decrease by 10-12 mg/100 gm in all the juice blends. The antioxidant potential gradually decreased during the storage period from 50.5 in 10% to 56.1 in 25% juice blends. The mean overall acceptability scores of more than 8 for juice blends samples up to 20% basil extract incorporation indicated the commercial scope for manufacturing good and nutritious juice blends, which will also be helpful in providing good antioxidant and nutraceutical potential to the consumer. Heat pasteurisation (90°C for 25 sec) and basil and ginger extract were more effective for inactivating the microbial flora. However the shelf life of the juice blends was established within 10 days, after this the acceptability decreased. The product is recommended children, youth and elderly persons to be used within 10 days.
