Effect of packaging on postharvest quality of mulberry fruit cv. Kamphaeng Saen 42

Abstract

Mulberry fruit cv. Kamphaeng Saen 42 are short shelf-life and unacceptable for customers(1-2 day) under stored at ambient condition. In order to solve the problem, the objective of this research was to study the effect of packaging on postharvest quality of mulberry fruit cv. Kamphaeng Saen 42. The study was conducted at Postharvest Quality and Storage System Laboratory, Division of Agri-Science and Technology (Postharvest Technology), Faculty of Bioresources and Technology, King Mongkut’s University of Technology Thonburi during March-April 2019. The experiment was laid out in Completely Randomized Design (CRD) with four replication and four treatments consisting of 1) unpacked fruit (control) 2) packed in low density polyethylene bag (LDPE) 3) placed on foam tray and wrapped with polyvinyl chloride (PVC) and 4) packed in polyethylene terephthalate (PET) plastic box and then stored at 10±2 ºC, 90±2 % relative humidity (RH). The results showed that fruit packed in LDPE bags retarded the changes of color, weight loss and suppressed disease incidence in mulberry fruit. Due to it had low O₂ and high CO₂ inside the package. Whereas, there was no effect on TSS and TA.
