Effect of Uni-Packaging on the Post Harvest Behavior of Citrus Fruits in N.W.F.P.

Abstract

A 45 days storage experiment was conducted to investigate the effect of Uni-Packaging treatments on the shelf life of citrus fruits. Different treatments were polyethylene bags of 0.0254mm, 0.0508mm thickness and control. The result showed that the uni-packaging had no significant effect on the pH of citrus fruit. Weight loss increased significantly as storage increased. Maximum weight loss observed in control and minimum weight loss in thick packaging (0.0508mm). The T.S.S increased during storage but individual packaging had non-significant effect on the T.S.S. Ascorbic acid decreased from 1.59-0.63% during storage. The organoleptic properties evaluation revealed that individual packaging had significant effect on the external appearance, taste and texture. Thick packaging perform significant effect in prolonging the shelf life of citrus fruit.

Tree Age and Harvesting Season Affected Physico-chemical and Bioactive Compounds of Elite Type of Gunda Gundo Orange (Citrus Spp) in the Northern Ethiopia

“…Orange has been identified as one of the main dietary sources of bioactive compounds (Gonzalez-Molina et al, 2010;Hounsome et al, 2008;Hussain et al, 2004;Lorente et al, 2014;Marti et al, 2009). It contains antioxidants (Gonzalez-Molina et al, 2010;Lorente et al, 2014;Tripoli et al, 2007), vitamin C (Hounsome et al, 2008;Marti et al, 2009), vitamins, and minerals (Supraditareporn and Pinthong, 2007;Wardlaw et al, 2004).…”
