The present investigation was carried out to study the response of different chemical treatment on shelf-life and quality of tomato fruits. The fruit samples were drawn and analysed periodically for various physical and bio-chemical changes. In summer results revealed that tomato fruits treated with post harvest treatments of KMnO4+ BLE reduce ripening and gave maximum marketable fruits with increased shelf-life of tomato fruits. The minimum loss in weight was noted when tomato fruits treated with 2 per cent bael leaf extract. The fruits treated with KMnO4 3000 ppm + 2 per cent BLE increased the per centmarketable fruits with increase in storage period. Maximum shelf-life (10 days) was observed in fruits treated with KMnO4+ 2000 ppm + 2 per cent BLE and KMnO4+ 2000 ppm alone. Maximum acidity was recorded in T1 with 2 per cent bael leaf extract. Ascorbic acid content was highest with the post harvest application of GA3 400 ppm in combination with 2 per cent bael leaf extract. The fruits treated with GA3 increases TSS, reducing sugar and total sugar at initial and later stage of storage, but acidity was increased at later stage of storage. Maximum percentage of reducing and total sugar was recorded in control condition.

Abstract


The present investigation was carried out to study the response of different chemical treatment on shelf-life and quality of tomato fruits. The fruit samples were drawn and analysed periodically for various physical and bio-chemical changes. In summer results revealed that tomato fruits treated with post harvest treatments of KMnO4+ BLE reduce ripening and gave maximum marketable fruits with increased shelf-life of tomato fruits. The minimum loss in weight was noted when tomato fruits treated with 2 per cent bael leaf extract. The fruits treated with KMnO4 3000 ppm + 2 per cent BLE increased the per centmarketable fruits with increase in storage period. Maximum shelf-life (10 days) was observed in fruits treated with KMnO4+ 2000 ppm + 2 per cent BLE and KMnO4+ 2000 ppm alone. Maximum acidity was recorded in T1 with 2 per cent bael leaf extract. Ascorbic acid content was highest with the post harvest application of GA3 400 ppm in combination with 2 per cent bael leaf extract. The fruits treated with GA3 increases TSS, reducing sugar and total sugar at initial and later stage of storage, but acidity was increased at later stage of storage. Maximum percentage of reducing and total sugar was recorded in control condition.
