摘  要:
蓝莓在高果糖浆(70±1°Brix)和不同渗透温度(45、55、65℃)条件下,不同的渗透液温度处理对蓝莓VC的损失有不同影响,其中以渗透液温度65℃处理对VC的含量影响最大,45℃下渗透脱水VC的损失最少。在5±1℃贮藏时蓝莓干中的花色苷比在22±1℃贮藏时稳定性好。光照使蓝莓干在贮藏过程中总花色苷残留率迅速下降,而暗箱贮藏使蓝莓干在贮藏过程中总花色苷残留率下降缓慢。

摘  要:
For blueberries immersed in high fructose corn syrup(70±1°Brix),the osmotic dehydrating temperature influences the content of vitamin C in the blueberries,especially at 65℃ vitamin C is lost largely,while at 45℃ its loss is the lowest.Moreover,the stability of anthocyanin in dried blueberries stored at 5 ± 1℃ is better than that stored at 22 ± 1℃.During the storage with light,the content of anthocyanin in dried blueberries decreases rapidly,while stored in the dark it decreases slowly.
