Abstract

This study was conducted to select polyethylene film for MAP during storage of cherry tomato. Treatments were conducted with different low density polyethylene (40 µm and 30 µm LDPE) and polyethylene (30 µm PE) films. Packed fruits were stored at 10ºC with 85±5% relative humidity (RH) and data were taken in 3 days interval. There was significant difference in titratable acidity (TA), surface color, lycopene content, firmness, weight loss, ethylene production rate and respiration rate during the entire storage period. After the 3rd day, pink stage tomatoes packed with 30 µm (LDPE) and 30 µm (PE) showed fast color development and attained peak on 9th day with Hunter`s a* values of 9.69 and 9.02 respectively. Afterwards, there was discoloration in both types of films. Whereas, there was slow color development of fruits sealed with 40 µm (LDPE) and reached its peak (10.45) on 15th day in pink maturity stage. 40 µm (LDPE) also maintained other quality parameters to meet consumers demand and to prolong the time frame for buyers and sellers. Moreover, there was no formation of fog in 40 µm (LDPE) and it is possible to look at the condition of the fruit while transporting.
