| Description |
The present investigation was carried out in the post harvest laboratory of the Department of Horticulture at CCS Haryana Agricultural University during the year 2004-2005. The main objective was to know effect of plant extract on shelf life and quality of aonla during storage at room temperature. The different plant extracts used were neem, eucalyptus, marigold and mahendi 2% and 5% in pre harvest and 5% and 10% concentration in post harvest. Neem 2% and 5% in pre harvest and 5% and 10% in post harvest dip treatment were most effective in checking the PLW and decay loss. There were continuous decrease in specific gravity. TSS, non-reducing sugars and total chlorophyll irrespective of the treatments. However, acidity, ascorbic acid, total sugars, reducing sugars and carotenoids showed an increasing trend. Fruits treated with different treatments were mainly infected with Penicillium sp., Fusarium sp. and Aspergillus sp. Slow occurance of pathogenic fungi was recorded in fruits treated with neem followed by mahendi and eucalyptus, fruits treated with neem effectively retained the TSS, acidity, ascorbic acid, sugars and carotenoid content of the fruits. Neem treated fruits showed least PLW and decay loss. |
