Abstract:
Guava (Psidium guajava L.), having 2n=22, belongs to the family Myrtaceae and is native of Mexico. Guava has limited storage potential at ambient conditions, which leads to glut in market and poor return to the growers. Moreover, over ripe fruit at ambient conditions lead to lot of wastage and economic losses. Post-harvest losses can be minimized by adopting proper post-harvest handling practices and better understanding of biochemical control of fruit ripening. Postharvest life of fruits and vegetables can be extended by using LDPE and HDPE films these films are commonly used to minimize weight loss, reduce abrasion, damage and delay. fruit ripening in view of above information an experiment is proposed to be conducted with following objectives,1) To increase the post-harvest life of guava fruits under ambient condition.2) To study the effect of packaging materials on and quality and shelf life of guavafruits. The experiment on “Some aspects post-harvest handling of guava cv.Khaja as influenced by packaging materials” was conducted during the period of December 2015-January 2016 inthe department of Post-Harvest Technology of Horticultural Crops, Faculty of Horticulture, Bidhan Chandra Krishi Viswavidyalaya, Nadia, to study the effect of treatments on quality of guava fruits. The cultivar of guava Khaja was harvested at mature but unripe stage. The guava fruit was packed in different microns of LDPE packages (1% LDPE+KMNO4, 2% LDPE+Kmno4 non purporated LDPE and control HDPE packages (1% HDPE+KMNO4, 2% HDPE+Kmno4 non purporated HDPE and control packaging. All treatments were kept in ambient condition. The fruits were examined for Tss Sugars, Acidity and Vitamin-C. The treatments which not only extended the shelf life and increased marketable fruits but also reduced the post –harvest losses without adversely affecting the fruit quality of guava.These treatments are found obviously easy for practical application for extending the shelf life of guava.
