A Study on Shelf-life Extension of Sweet Corn

The freshly harvested Sweet Corns (Zea Mays L.) were packed in different packaging materials like low density polyethylene (LDPE) with (0.2%) and without ventilation, MAP using diffusion channel and silicone membrane, vacuum packing and Shrink wrapped materials stored in refrigerated conditions. The temperature 0 °C was maintained to evaluate the nutritional quality of sweet corns. Among six different packaging systems tested for the sweet corn storage, the least value of PLW (0.533%), better retention of total sugar in corn kernels without conversion into starch, maximum shelf-life (16 days) and high sensory quality was documented with shrink wrapping package system which showed encouraging results with respect to physical properties and sensory quality evaluation when compared with the other treatments.
