　　Temperature at 0-2℃ and relative humidity at 95-100% are well known as ideal storage environment for asparagus spears.The quality preservation of spears stored in a snow vault was compared with those stored in an electric refrigerator.Asparagus spears of Grande and Gijinlim were stored in a snow vault and a refrigerator for 0, 2, 5, 10 and 20 days, then 1) physical characteristics such as hardness, weight and surface color and 2) inner quality such as brix, sugar, ascorbic acid and rutin content in the spears were investigated.In terms of the storage environment, though temperature and relative humidity fluctuated largely at 3-6℃ and 65-85% in the refrigerator, temperature and relative humidity were almost stable at 0-1℃ and 100% in the snow vault.
