Quality of cauliflower as influenced by film wrapping during shipment.

Winter-grown cauliflowers cv. Siria, grown in Spain, from 3 harvesting periods (January, March and April 1997) were film-wrapped using polyvinyl chloride (PVC; 14 micro m), low-density polyethylene (LDPE; 11, 15 or 20 micro m) or microwavable LDPE (11 micro m), and stored for 1 week at 1.5 deg C to simulate a period of commercial shipment. After cold storage, cauliflowers were kept for 2.5 days at 20 deg C to simulate a retail sale period. Soluble solid content, pH, titratable acidity, weight loss, physiological disorders, fungal attacks, visual quality and gas composition within packages were monitored. After the shelf life simulation, among the LDPE films studied, the best results were obtained in the 11 micro m LDPE treatments. Gas composition (about 16% O2 and 2% CO2 during cold storage, and about 11% O2 and 3.5% CO2 during retail sale simulation), overall quality, yellowing and browning of the head, and Alternaria spp. development were at similar levels among the films studied. Weight loss

was considerably lower for LDPE films than for the PVC film.
