Abstract:
The effect of different materials of packaging namely polyvinyl chloride (PVC) shrink
film, polyethylene (PE) plastic and unpacked was evaluated for storage of tomatoes.
The samples were stored at ambient temperature and 1 o0c. Changes in fruit quality
were evaluated at interval 2 days. Observations were made on weight loss, surface
colour development, firmness, and total soluble solid (TSS) contents. The percentage
at weight loss of unpacked tomatoes was significantly (p<0.05) increased during
storage at ambient temperature and temperature I o0c. It caused faster dehydration.
This occurrence can be prevented by using PVC shrink film and PE plastic packages.
Tomatoes packages in PE film softened and not firm which might be due to
condensation of water vapour from respiration and low 02 content in packages in both
the storage conditions. Surface cal our development of tomatoes during storage shows
that the temperature at 10
°
c
had effectively inhibited the senescence of the fruit
compare the fruit stored at ambient temperature. The storage life of tomatoes stored in
ambient temperature can be maintained for IO days. However, at temperature I o0c
the product can be stored for 14 days. PVC shrink film can be used foe commercial
packaging of tomatoes at ambient temperature and 1 o
0c
compared to PE film and
unpacked tomatoes.
