Abstract

The effects of 1-MCP post-cutting treatment on fresh-cut white dragon fruit were investigated in order to assess its potential in storage quality improvement. Measure white dragon fruit were sanitized with CIO2 prior to fresh-cut processing. Gaseous 1-MCP was injected to fresh-cut fruits packed in polyethylene terephthalate (PET) trays with polyvinyl chloride (PVC) stretch film overwrap. Samples were stored at 5-10 deg C and monitored for storage quality parameters. In this study, 5ppm 1-MCP post-cutting treatment increased antioxidant activity (AA) significantly, delayed translucency, and decreased titratable acidity (TA). pH, total soluble solids (TSS), titratable acidity (TA) and TSS/TA ratio were unaffected. Headspace C2H4 were higher than in control. Visual quality deterioration and development of water-soaking were delayed. Respiration rate was lowered. Lower yeast and molds count, aerobic plate count and coliform count were observed in samples with 1-MCP treatment. Post-cutting treatment with 1-MCP positively affects storage quality of fresh-cut white dragon fruit. Based on visual quality, fresh-cut white dragon fruit will last for 14 days. However, based on coliform count, microbial limits were reached at day 5 of cold storage.
