제주산 궁천조생의 저장조건에 따른 저온저장 특성을 검토하였다. 상온저장에 비해 저온저장 감귤은 저장기간 중 가용성 고형물, 총당, 비타민 C의 변화가 매우 적었으며, 부패율과 중량감소가 각각 10% 이내 수준에서 비교적 신선도를 유지한 상태에서 3월 하순까지 저장이 가능한 것으로 보였다. 또한, 중량감소, 경도의 저하, 당함량의 감소는 저장기간 중에 계속하여 서서히 일어났다. 필름포장과 wax-coating은 중량감소와 외관향상에는 도움을 주었으나 장기간 저장에는 부패율이 증가하였다. 습도조절을 하지 않은 저온저장은 습도조절한 경우와 비교하였을 때 부패율과 중량감소가 컸다. 증산작용으로 인한 껍질수분의 감소에 따라 과육으로부터 수분이동이 발생하여 저장기간 중 과육율이 감소하였으며, 저장 60일 후부터 경도저하가 많이 일어나 조직이 연화됨을 알 수 있었다. 조기수확한 감귤에 비하여 완숙한 감귤이 부패율과 중량감소가 적어 저장 100일간을 기준하여 출하하는 것이 바람직하였다. 상온저장한 감귤에 비해 저온저장한 감귤은 저장 4개월 이후 출고하였을 경우 외관 및 맛에 비교적 우수하였으며, 출고후 필름포장한 감귤의 부패율은 급속히 증가하여 취급에 주의가 필요하였다. 조생온주의 경우 저온에서 장기간 저장이 어려움을 알 수 있어서 저장용 감귤의 특성을 고려하여 저장조건을 설정할 필요가 있었다. The conditions of cold storage of Citrus unshiu Marc. var. miyagawa produced in Cheju were investigated. Compared to the citrus fruits stored at room temperature, the content of soluble solids, total sugar, vitamin C and specific gravity decreased slightly on the fruits stored at $4^{\circ}C$ and 87% relative humidity. Decay ratio and weight loss were below 10% on keeping freshness relatively till late of March during cold storage. Weight loss, decrease of firmness and soluble solids occured gradually during cold storage. Nevertheless seal-packaging with 0.02 mm LDPE film or wax-coating of citrus fruits were effective on weight loss and appearance, decay ratio increased for long-term storage. It was needed to control humidity in cold chamber for preventing from decay and weight loss. Edible part ratio was decreased gradually by respiration, and peel and tissue of fruits were softened slightly by 60 days of cold storage. Decay ratio and weight loss of full-ripened citrus fruits were little during the storage for 100 days, compared to the fruits harvested early. Appearance and taste of citrus fruits stored for 4 month were good relatively, but decay occured rapidly on seal-packaging fruits putting out of cold room for a few days. Because of the difficulty of long-term storage for early variety of Citrus unshiu, the conditions and periods of cold storage would be determined after considering the physicochemical properties of fruits.
