녹색꽃양배추의 MA 소포장 시 기능성 트레이가 에틸렌, 이취관련물질 흡착 및 품질에 미치는 영향

다국어 초록 (Multilingual Abstract)

This study was carried out to investigate effect of the charcoal paper tray in MA packaging on the absorption of detrimental gas and quality change of broccoli florets, and to examine weather it could be used as environmently sound functional tray instead of the present plastics tray. The O₂ content of 4-5% was maintained in all treatments during storage period, but the CO₂ content was rather lower in the pulp and charcoal paper treatments than in the control treatment. The ethylene content, also, was 0.77 ppm lower in the charcoal paper treatment than in the control treatment after 15 days. Additionally, acetaldehyde and ethanol contents were about 2 times lower in charcoal paper treatment than in control and pulp paper treatments. The Hunter ‘b’ value, an indicator of yellowing, was increased quickly after 10 days in the control and pulp paper treatments, but that in the charcoal paper treatment was not almost changed during storage period. The ascorbic acid and total chlorophyll contents were decreased remarkably in control and pulp paper treatments after 15 days, but these in the charcoal paper treatment were maintained highly during storage period. The marketability was extended from 5 to 10 days. Weight loss in charcoal paper treatment was some higher than that in other treatments, but marketability loss was not caused by weight loss.
