Abstract
Research was conducted on two broccoli cultivars (Tambora and Kermit) during two years. Influence of polyethylene film on physical and chemical changes, (total acidity, pH values, vitamin C (ascorbic acid), total chlorophyll, and total carotenoid) as well as gas permeability of polyethylene film were investigated. Average broccoli inflorescence were stored, at 4°C temperature and 95% of air humidity, without polyethylene film (-PE) and packed in polyethylene film (+PE), for ten days. Broccoli mass lost, in the samples stored in (+PE) mass loss was negligible and through both years of the research it was around 0.25 %. Higher mass loss (9.84%) was recorded in the samples without polyethylene (-PE). Loss of vitamin C in (+PE) samples was in average 8.09%, and in (-PE) samples it was 18.08%. Measured values of pH were aligned in both storage systems, and ranged from 6.28 to 6.80. This was also the case for total acid values expressed as g/l of citric acid, which ranged from 1.01 to 2.30 g/l. Chlorophyll loss was in average 20.44% for (+PE) storage of samples, and 27.93% for (-PE) samples. Carotenoid loss in (+PE) samples was in average 75.68%, and in (-PE) samples it was around 78.55%. In both research years, air permeability values of polyethylene film ranged from 239 to 463 cm 3m-2d-1 bar1. It is determined that packaging of broccoli in polyethylene film and storage at 4°C and 95% humidity, can maintain its quality during 10 days.
