Aonla and papaya fruits had average fruit weight (29 and 1549 g) and pulp weight (835 and 779 g/kg fruit), respectively. Yield of pulp was more in aonla fruit (83.5%) than papaya fruit (77.9%). Total soluble solids, total sugars, reducing sugars and total carotenoids were found more in papaya fruit than aonla fruit, while acidity, ascorbic acid, pectin and total phenols were recorded more in aonla fruit than papaya fruit. Jam prepared from blend (0 aonla: 100 papaya) got the highest overall acceptability (8.48) followed by jam prepared from blend (40 aonla: 60 papaya) with overall acceptability (8.25). Chutney prepared from blend (0 aonla: 100 papaya) got the highest overall acceptability (8.05) followed by chutney prepared from blend (40 aonla: 60 papaya) with overall acceptability (7.85). Overall acceptability of aonlapapaya jam and chutney decreased significantly during three months storage but both the blended products remained acceptable even after three months storage. Total soluble solids, total sugars, reducing sugars, and browning increased significantly, while acidity, ascorbic acid, total carotenoids and total phenols decreased significantly in aonla-papaya jam and chutney during three months storage period. Total plate count and mold count increased significantly in aonla-papaya jam and chutney during three months storage period. In aonla-papaya jam, cost of production was recorded maximum (`69/kg) in treatment (0 aonla: 100 papaya) and minimum (`32/kg) in treatment (100 aonla: 0 papaya). In aonla-papaya chutney also, cost of production was recorded maximum (`60/kg) in treatment (0 aonla: 100 papaya) and minimum (`37/kg) in treatment (100 aonla: 0 papaya).ennullThesis
