Effect of Different Plastic Packaging on Postharvest Quality of Tomato (Lycopersicon Esculentum Mill.)

Tomato is highly perishable in nature and incurred high post-harvest losses due to unsuitable packaging method. Experimentation was undertaken to find the effect of different polymeric film packaging on postharvest quality of tomato var. Manisha in a completely randomized block design (CRD). There was five treatment viz. open, ordinary plastic, Polypropylene (PP38,) Low-Density Polyethylene (LDPE38) and 25) which was replicated four times. Destructive and non-destructive samples were prepared for each treatment, non-destructive samples were sealed completely and used for weight loss observation and destructive samples were tied with a rubber band and used for observation of Titratable Acidity (TA), Total Soluble Solid (TSS), pH and firmness every four days after packaging. Among the different packaging treatments, no packaging (open) showed the highest percentage of weight loss (13.25%), lowest firmness (3.35 kg), and highest TSS (4.33) at the final day of storage as compared to another plastic packaging. The plastic packaging creates a modified atmosphere for the packed tomatoes which slows down the physiological processes and delay ripening, causes minimum weight loss, delays a change in color, and lower TSS content of the tomato fruit. So, packing tomatoes in any type of plastic packs is suitable for increasing shelf life.
