Abstract
民國72年本所研究將柑橘裝籃後以伸縮膜繞封包裝再貯藏之方故，得知該方法可較傳統之逐果套袋包裝者省工及維持同樣良好之果實品質，但會造成5~7倍之高腐爛率。為改善此缺點，本研究試驗改善包裝方式以降低果實貯藏環境過高之濕度。並試用霉敵(TBZ)煙燻劑於貯藏期間定期煙燻，結果在嘉義地區，柳橙以改良式伸縮膜包裝貯藏5.5個月後，腐爛率與逐果包裝者相似，各為14.7%及11.9%，綠蒂率則較高，各為50.7%及37.2%，果實失重率、密度、糖、酸含量等則無差異。在東勢地區，以椪柑貯藏3個半月後，腐爛率各為0.7%及2.7%，綠蒂率各為64.2%及55.3%，果實失重率、密度、糖、酸含量等亦無差異。顯示改良式伸縮膜包裝方式不僅改善了舊式之缺點，並較傳統之逐果套袋方式有更好的效果。
Fruits of ‘Ponkan’ (Citrus reticulata) and ‘Liucheng’ (Citrus sengensis) were tested for shrouded packaging with polyethylene (PE) stretching film for long term storage. High decay ratio due to high humidity inside the package was lowed by laying newspapers on the top of fruits. The decay ratio of ‘Liucheng’ fruit after 5.5 months of storage was 14.7% in film shrouded packaging which was similar to 11.9% in individual fruit PE bagged packaging. No significant difference between two kinds of packaging was observed in fruit qualities including weight loss, total soluble solids content and titratable acidity. Fruits with green calyx button in film shrouded packaging was 50.7% which is higher than 37.2% in bagged packaging. For ‘Ponkan’ fruit, the decay ratio after 5 months storage were 0.7% and 2.7% in shrouded packaging and bagged packaging respectively. The ratio of fruits with green calyx button were 64.2% and 55.5% in shrouded and bagged packaging respectively. The fruit qualities were similar in both two packagings after storage.
