| Description |
Mango (Mangifera indica L.) is considered as one of the choicest fruits of the world because of its attractive colour, delicious taste and excellent nutritional value. The interest in fruit crops has increased due to increase in exports and income potential. Especially mangoes are in increasing commercial importance all over the world. However, errors in determination of harvest maturity and post harvest handling practices are resulting in post harvest damage and consequent economic losses to farmers and exporters. Hence, post harvest management of mangoes is important in conservation and maintenance of quality of this fruit. Keeping these points in forefront, the present investigation was executed with the objectives to find out suitable harvest maturity stage, post harvest ethrel treatment and polypropylene packaging for improving the shelf life and quality of mango cv. Suvarnarekha. The present investigation entitled “Studies on effect of post harvest ethrel treatment and polypropylene packaging on shelf life and quality of mango cv. Suvarnarekha at different stages of maturity” was carried out during year 2012 at Fruit Research Station, Sangareddy. A set of two experiments were carried out to evaluate the effect of post harvest ethrel treatment and polypropylene packaging on physico-chemical parameters i.e., PLW, firmness, colour score, spoilage, shelf life, sugars, acids and organoleptic score at different stages of maturity, which were recorded at an interval of 3days at ambient temperature. Among the maturity stages, mango fruits harvested at later stages of maturity recorded increase in weight loss, colour score, spoilage, sugars and decrease in firmness, titrable acidity and ascorbic acid. However, mango fruits harvested at 9-11°B TSS stage recorded better physico-chemical parameters and organoleptic score with higher shelf life of 6.50 days. With respect to studies on the post harvest ethrel treatment, ethrel at a concentration of 500 ppm recorded better fruit firmness, sugars, shelf life and organoleptic score with good flavor, texture and overall acceptability. Among the treatment combinations, mango fruits harvested at 9-11°B TSS stage with 500ppm recorded better physico-chemical parameters and organoleptic score with higher shelf life of 6.67 days. In experiment II, best treatment combination of experiment I was packed in polypropylene bags, retained better fruit firmness, texture, overall acceptability and lowered physiological loss in weight thereby extending the shelf life of mango as compared to control (unpacked fruits). Among the treatments, mango fruits packed in 150gauge with 1% ventilation recorded lower physiological loss in weight, higher firmness, organoleptic score with a shelf life of 9 days. In conclusion, Mango cv. Suvarnarekha harvested at 9-11oB TSS treated with ethrel at a concentration of 500ppm and packed in polypropylene bags of 150 gauge with 1% ventilation was effective in maintaining the quality and extending the shelf life upto 9.0 days at ambient temperature. |
