Abstract
In Japan, fruits and vegetables are usually transported through the summer season at 10– 20°C after precooling .We studied methods for improving storage quality of broccoli, by enclosing the heads in film perforated with 70 μm diameter holes.
Four types of film were used having different hole densities, and giving air permeances of (A) 7 to 8.3, (B) 10.9 to 12.8, (C) 16 to 19 and (D) 25.6 to 32 1/day·atm.
For each treatment, 15 broccoli heads, cv. ‘Ryokurei’, precooled overnight at 3°C, were enclosed in a 45 x 60 cm film packages, and after heat sealing put into cartons.
Some samples were stored for 7 days at 20°C and others for 11 days at 10°C. Broccoli quality during storage was graded from 5 (harvest freshness) to 3 (barely marketable) to 1 (inedible). After storage we measured chlorophyll, vitamin C and soluble sugar contents of the heads, and gas compositions inside each bag.
