Abstract:
The objective of this research work wastodevelop atechnology for preparation of fruit bar from papaya and guava pulp and to study the changes in chemical composition and sensory properties of fruit bar during storage in butter paper with metallic paper and polyethylene bag. Preliminary studies were carried out to standardize the optimum levels papaya and guava pulp with pectin. Fruit bar prepared from this combination were found to be better than other combinations in respect to organoleptic properties and nutritional quality. The fruit bar prepared were wrapped in butter paper with metallic paper, polythene bag and stored at ambient (27 ± 2 0C) for 180 days. The stored samples were drawn periodically at 30days interval for organoleptic and chemical analysis.
The chemical composition indicated that the fresh fruit bar contained on an average moisture 15.80 percent, TSS 74.70 0Brix, titrable acidity 0.97 percent, total sugars 68.05 percent reducing sugar 16.68 percent and ascorbic acid 120.37 mg/100 g, calcium 8.74 mg/100g and β-carotene 132.74 µg/100g. The mean score of fresh fruit bar for colour and appearance was 7.71, texture 7.20, flavour 7.86, taste 7.71 and overall acceptability 7.75 on 9 point hedonic scale. The cost of fresh fruit bar was ranged from Rs. 568 per kg for various combinations of ingredients. The storage study indicated that the TSS, reducing sugars, acidity and total sugars increased with the advancement of storage period, while moisture content, ascorbic acid, calcium and β-carotene decreased. The rates of increase or decrease were relatively higher polyethylene bag than butter paper with metallic paper packaging material. The fruit bar prepared from 30% sugar, 2% pectin, 1% citric acid and 60% guava + 40% papaya pulp was found superior over other combinations in respect of organoleptic properties throughout storage period. However, fruit bar were found to be acceptable even after 180 days storage at ambient conditions in both packaging material.
