Abstract

Ethylene absorbents can increase the shelf life of fruits and vegetables since they scavenge away ethylene hormone, responsible for fruit ripening. Such a technique is used in increasing the shelf life of ripe tomato. Ripe tomatoes, after washing and removal of surface moisture were packed in polypropylene (200 gauge) packets with 0.002% perforation and without perforation. Chalks treated with different concentrations of KMnO4 (1500 ppm-2500ppm) were kept inside the polypropylene packets, along with the tomatoes. Tomatoes packed in perforated (0.002%) polypropylene (200 gauge) packets with 2500 ppm KMnO4 treated chalks had the shelf life of 28 days in cold storage (04±5◦C and 85% RH) and 14 days in room temperature storage (24±5◦C and 70% RH). Analysis of the samples were carried out and it was found that KMnO4 (2500ppm) + perforation showed minimum decay percentage, and slow rate of changed in TSS, colour ‘a’ value and lycopene content, while maximum value was recorded for fruit firmness, acidity, ascorbic acid by the treatment.
