Individual film wrapping of Nagpur mandarin (Citrus reticulata Blanco) with heat-shrinkable and stretch-cling films for refrigerated storage.

Heat-shrinkable (50 micro m) low density polyethylene (LDPE) and stretch-cling (15 micro m) linear low density polyethylene (LLDPE) films were evaluated for individual wrapping of Nagpur mandarin fruits to extend their shelf life under refrigerated storage conditions (6-7 deg C; 90-95% RH) during the Mrig crop season of 1997. Wrapping fruits reduced water loss drastically (1-2%) in both the films compared with non-wrapped fruits (13.29%) at the end of refrigerated storage (60 days), followed by a 2-day holding period in ambient conditions. Two preharvest sprays with carbendazim (500 ppm) and a postharvest wash with chlorine (1000 ppm), followed by carbendazim (2000 ppm) treatment minimized decay (1-3%). Colour development was not adversely affected either by heat-shrinkable (LDPE) or stretch cling film (LLDPE). Respiration rate was low in film-wrapped fruits. Fruit firmness decreased in wrapped fruits, but not in controls. Flavour and overall acceptability scores were highest in stretch-cling fi

lm-wrapped fruits at the end of storage.
