Effect of different polymeric films on shelf-life and quality of pear fruits under supermarket conditions

Pear fruits cv. ‘Patharnakh’ were harvested at physiological maturity, packed in paper moulded tray and tightly wrapped with different packaging films, viz., low density polyethylene (LDPE), high density polyethylene (HDPE), shrink and cling films. The film-packed fruits and control (without film packaging) were stored under super market conditions, i.e., 20–21°C and 90–95% RH and analysed for various physico-chemical parameters at weekly interval. Shrink film proved to be most effective in extending the storage-life of pear fruits up to three weeks and maintained superior quality as indicated by lower weight loss, desirable fruit firmness, total soluble solids, total sugars, acidity, and higher organoleptic score.
