| 摘 要： | 以津鲜1号普通玉米、津甜玉米、津白糯糯玉米为试材,研究了不同采收成熟度(乳熟期和成熟期)的鲜玉米在0~1℃贮藏过程中碳水化合物(可溶性糖、蔗糖、淀粉)含量的变化。结果表明,采收成熟度对玉米的贮藏品质影响较大,乳熟期采收的嫩玉米比成熟期采收的玉米可溶性糖和蔗糖含量高,淀粉含量低,在贮藏过程中的变化小,贮藏品质好,并可延长贮藏时间。因此,鲜食玉米应选择乳熟期采收的嫩玉米进行贮藏。

| Abstract: | The variations in carbohydrate content （soluble sugar, sucrose and starch） in flesh corn with different harvest maturities （milk stage and maturity stage） storaged at 0-1 ℃ were studied by using varieties of Jinxian No.I, Jintian Sweet and Jinbai Sticky as raw materials. The results showed that, harvest stage had great effect on storiability. Compared with maturity corn, in young corn, the soluble sugar and sucrose contents were high, the starch content was low, the changes of them during the storage were small. Storage quality was better in young corn than maturity corn, and the storage period was prolonged. So, the fresh corn should choose the young corn with milk stage to storage. |
