During the last few globe. decades scientific advances, social campaigns and interests in yoga and yogic way of life Time is ripe for total integration of food have made people aware of the role of diet in processing and waste utilisation to make the maintaining overall general health and processing eco-friendly. Food processing is combating chronic diseases. People one of the priority sectors visualized by the throughout the world are tending to avoid Government of India.

Human history has been inextricably The "Rainbow Revolution" in the aftermath of entwined with our search for and discovery of the green and the white revolution stresses on new foods and drinks. Indeed, human the need to conserve the vast resource of 3084 Int.J.Curr.Microbiol.App.Sci (2018) 7(11): 3084-3095 fruits and vegetables with emphasis on the Water reduction of post-harvest losses. Value can be added to a commodity by upgrading its Essential steps in the treatment of water are as quality, reducing its perishability, extending chlorination, coagulation, clarification, lime shelf life, ensuring off-season availability, softening, filtration through sediment filter or changing their form and purity as required in activated carbon filtration. Khurdiya (1989b) the market, transportation and marketing in developed carbonated beverage and suggested remunerative markets. that water for soft drinks must be clear and free from heavy metals, organic matters and Fruit juices occupy a unique position among must have low alkalinity. those products classified as beverages.

The (Ramchandran, 1988) commercial viability of fruit juices in the preparation of carbonated drinks is practically Sugar limited. Inclusion of a fruit juice in soft drinks will not only impart its characteristic color, Relative importance of color, fruity flavor and taste and aroma but also obviates use of sweetness in overall liking of soft drinks was synthetic additives and has some nutritional studied. The presence of flavourant value. If fruit juices are added to these significantly influence overall liking (Tuorila sweetened aerated waters, they not only et al., 1984). The natural sweeteners which impart nutrition but there is no need of are nutritive include sucrose, liquid sucrose, synthetic additives. It may provide some more liquid invert sugar, fructose, etc. Generally diversification to the soft drinks. sucrose is used as sweetener. The synthetic sweeteners are saccharin, cyclamates, Carbonation of juices may also improve aspartame, etc. and have no nutrition aroma, taste and nutritive value of the (Khurdiya, 1989a). beverages. Finally, one could think of a new product development through carbonation in Acidulants the form of a natural health drink, which would also serve as appetizer. Juicy fruits like It has been reported that various acids such as amla and lime can be successfully citric acid, tartaric acid, ascorbic acid, fumaric transformed into drinks.

Ingredients for carbonated beverage It blends well with most of the fruit flavors. For preparation of carbonated beverages, the Phosphoric acid is mainly used in cola ingredients required are sugar, water, beverages. Ascorbic acid may be used to add acidulants, flavourings, colouring, carbon vitamin C and it also acts as an antioxidants dioxide, clouding agents and emulsifiers.
