부추저장 중 포장재별 중량감소는 LDPE, PP 및 HDPE film처리가 포장재간 큰차이 없이 1% 미만의 매우 작은 감소를 보였으나, 무포장은 저장기간이 경과할수록 감소율이 현저히 증가하였다. 부추즙액의 당도는 입고시 6.0 Brix에서 무포장 2주째에 4.6 Brix로 크게 감소되었으며, LDPE film등 포장재처리는 밀봉처리에서 4.9-5.9 Brix로 감소폭이 적었고, 탈기처리시에는 4.5-4.7 Brix로 감소폭이 다소 큰 경향이었다
During the storage period of chives(Allium Tubersum fouler) at low temperature(4-5), weight loss in chives by the packages of LDPE, p.p and HDPE film was decreased less than 1%, however that of chives unpacked was remarkably increased as time went by. Soluble solids of unpacked chives was decreased from 6.0 to 4.6 Brix after 2 weeks storage and that of LDPE film sealed was lessened to 4.9-5.9 Brix, the treatment of deaeration showed a tendency to decrease a lot to 4.5-4.7 Brix. The vitamin C content of chives unpacked was 37.1mg% at before storage, but after one week decreased very much to 15.2mg%, and that in chives packed by the different methods was visibly lessened after 2 weeks storage. the Vitamin C content in chives processed by deaeration sealing method was lessened compared to that at chives processed by sealing only. In the bag of chives packed by HDPE film had low CO and CH concentration and the gas concentration in the bag of chives processed by P.P. film was increased as storage period went by. Conclusively the freshness of chives packaged by LDPE and HDPE film maintained for 3 weeks, at P.P film for 2 weeks, but the marketability of chives unpacked was degraded in 3-4 days.
