Cashew apple is a pseudofruit enriched in sugars especially reducing sugars (glucose and fructose), polyphenols, carotenoids, vitamins, minerals, organic acids, amino acids and fiber. Many value added products have been developed using cashew apples including fermented and unfermented food products. However, the fruit is still underutilized where more than 90% of the fruits are left in the orchards as waste, attributing to low shelf life, low palatability, limited market availability for value added products and lack of awareness among people. This invention focuses on utilizing the cashew apple in developing a sweetener which has high demand in the market, has wider applications in food industries and household, has longer shelf life and requires minimum inputs for production. Cashew apples are rich source of polyphenols including tannins (0.35%). These tannins along with uroshiols (3%) impart astringency to the cashew apple juice and its value-added products. Thus, it is very imperative to remove these compounds to enhance the palatability of the product. The process was standardized to remove astringency causing compounds from cashew apples and development of the jaggery from the resulting cashew apple juice. Cashew apple liquid sweetener has various minerals like potassium, zinc and iron and is high in soluble fibre and anti-oxidant activity. The glycemic index of this liquid sweetener comes...

The major consumption of grapes in India is as fresh followed by raisins, wine and juice. While at global level 78-80% grapes processed in to wine followed by raisin, fresh grapes and juice. The value addition in grapes and diversification of grape products also provide good returns to growers. The raisin industry is also gaining good results. A quantity of 105000 t raisins was produced during 2009. But, it is not possible without active involvement of food industry in value addition sector. Adding value to grapes may be as simple as creatively packaging the grapes. This might be washing and packaging the fruit for a ready-to-eat snack or placing the fruit in a decorative container either alone or with other fresh fruit as a “farm fresh gift basket.” A. Value added products 1. Raisins The dried grapes are known as raisins. The Thompson Seedless white and thin skinned grape variety has monopoly in the production of best quality raisins. At global level, about 90% of raisins produced by drying of Thompson Seedless and clones. In India, grape drying is performed under raisin...
