만생종 중립계 포도에 대한 저장성을 검토하기 위해 재배면적이 많은 Sheridan, Tano Red 및 Muscat Bailey A 등 3품종을 공시하여 저장전 SO훈증처리, 저장온도 , 습도 90% RH의 조건에서 polyethylene film으로 밀봉하여 저장성을 시험하였다. 중량 감소는 저장기간이 경과할 수록 많았으며, Sheridan 품종이 감소의 정도가 가장 적었다. 비정상과는 저장기간이 경과할수록 많았고, 저장 90일 이후 급격히 증
In an attempt to test the storage life of late maturing-medium grapes, Sheridan, Tano Red and Muscat Bailey A cultivated widely in Korea, were selected as test samples. These grapes were treated with SO2 gas and packed with polyethylene film, then stored at 0 under 90% RH. Total weight decreased with the storage days and the loss extent of Sheridan was the least. Abnormal grapes increased along with the storage days and occurred rapidly after 90% days. After 135 days, these were produced as the following order. Sheridan < Muscat Bailey A < Tano Red. The external appearances were deteriorated with the storage days. After 135 days, these indices of Sheridan, Muscat Bailey A and Tano Red wen 6.3, 5.0 and 1.7, respectively, showing the most satisfactory result from Sheridn. Water content decreased along with the storage days. The soluble solids content and the proportionality of sugar to acids increased with the storage days, however the titratable acidity decreased. Considering these results, the storage lifes were excellent by the order Sheridan, Muscat Bailey A and Tano Red.
