저장고 형태에 따른 온주밀감의 저장 중 품질특성을 검토하였다. 항균제로서 베프란(iminoctadime-triacetate) 2,000배 희석액, 키토산 1.5%에 0.5% CaCl를 혼합한 용액에 감귤을 충분히 침지하였다. 풍건시킨 후 26 L인 플라스틱 컨테이너에 감귤을 12 kg 정도씩 담아 3에서 24시간동안 저장전 처리를 하고, 상온저장과 내부온도 4, 상대습도 87%를 기준으로 저장하였다. CaCl를 함유한 키토산 용액을 처리한 감귤이
Quality changes of over-wintering satsuma mandarin (Citrus unshiu Marc. var. miyagawa) during storage by chitosan and calcium treatment and type of storage warehouse were investigated. Citrus were treated with 2000-folds diluted iminoctadime-triacetate solution and 1.5% chitosan with 0.5% CaCl solutions and were at 30 far 24 h before storage. The citrus of about 12 kg/26 L plastic container were stored at room temperature, and at 4 with 87% relative humidity. Chitosan and CaCl solution treated citrus fruits were showed lower in decay ratio than the ones without treatment. Also, these chitosan and calcium treated citrus fruits skewed less in weight loss, that seems it also has restraining effect of fruits' transpiration. Decay ratio of citrus with precise temperature and humidity control were lower than the others during storage. Weight loss, moisture content of peel and flesh were decreased slowly during storage. 0.84 ∼0.90% of acid content were decreased on 120 days' storage. Reducing sugar of citrus was decreased rapidly after 90 days, and vitamin C content were also decreased rapidly after 60 days during storage.
