Tomatoes can be kept field-fresh for three weeks without using cold storage, according to the researchers from the Laguna-based Philippine Horticulture Training and Research Center (PHTRC).
One economical alternative is to use the Evaporative Cooling and Modified Atmosphere Packaging (MAP) Technology which prolongs the storage life of fresh tomatoes under ordinary condition using locally available materials.
Developed by the team of Gloria Masilungan, Dr. Edralina Serrano and Kevin Yap, Evaporative Cooling and MAP Technology utilizes coconut coir dust and polyethylene (PE) plastic packaging and a suitable crate or container for storing tomatoes.
