Guava-Papaya jam was developed and evaluated for changes in its physico-chemical, microbiological and sensory parameters at monthly interval for three months storage period. Total soluble solids increased significantly, while acidity decreased significantly in guava-papaya jam with the advancement in storage period. Yeast and mold count increased significantly in blended jam during storage. The colour and appearance, flavour, taste, mouthfeel and overall acceptability of guava-papaya jam decreased significantly during storage, however, the products were found acceptable even after three months storage. Jam prepared with 40 guava: 60 papaya pulp ratio was found to be the most acceptable.

Chutney prepared from guava-papaya blends was analyzed for changes in chemical constituents and overall acceptability at monthly interval for three months storage period. Total sugars, reducing sugars and browning increased, while ascorbic acid, total carotenoids and total phenols decreased significantly in chutney during storage. Chutney prepared with 40 guava:60 papaya pulp ratio was most acceptable. The overall acceptability of chutney decreased significantly during three months storage period.

Carrot and beetroot are mostly used for salad and juice purpose. To know the physicochemical and bioactive composition of the locally grown carrot and beetroot, the present investigation was carried out. Physicochemical and bioactive compound like total soluble solids, total sugars, reducing sugars, titrable acidity, pH, ascorbic acid, total antioxidant activity, anthocyanins, betanin, total phenols and total carotenoids were determined from fresh carrot and beetroot juices. The results showed that fresh red carrot juice contained high amount of β-carotenoids (4.59 mg/100 ml) content. Freshly extracted beetroot juice contained 62.20% DPPH scavenging antioxidant activity, 990.7 mg/100 ml total phenols, 790 mg/l anthocyanins, 520.3 mg/l betanins. The results suggest that carrot and beetroot juices are rich source of nutrients and bioactive compounds thus can be used for value addition in food formulations.
