甜玉米含有一般植物内含量稀少的植物糖原,为此有必要查明甜玉米在成熟过程中,内含植物糖原与淀粉的组成比率以及含量变化。作者根据甜玉米籽粒的饱满度、风味、甜味和种皮硬度等判断来确定作为新鲜蔬菜食用的甜玉米的采收适期。将玉米须毛长出后第17～20天内采收的甜玉米为供试材料,把这4天所采收的甜玉米分别贮藏在30℃和2℃温度下,24小时后查明不同成熟期和贮藏过程中甜玉米内含游离糖含量的变化。结果表明:非还原糖在玉米须毛长出后第5～16天内有所增加,含量由第5天的2.5克/100克鲜重增加到第16天的4.0克/100克鲜重,但从第16天开
Sweet corn contains plant glycogen, which is rare in plants, so it is necessary to find out the composition ratio and content of plant glycogen and starch in the process of maturing sweet corn. Based on the plumpness, flavor, sweetness, and seed coat hardness of sweet corn kernels, the authors determined the appropriate harvest period for sweet corn consumed as fresh vegetables. The sweet corn harvested in the first 17 to 20 days after the growth of the corn sibiros had been taken as the test material, and the sweet corn collected in the 4 days was stored at 30 ° C. and 2 ° C. respectively, and after 24 hours, different ripened maize Changes of Free Sugar Content in Sweet Corn During Storage and Storage. The results showed that the content of non-reducing sugars increased from 2.5 g / 100 g fresh weight on the fifth day to 4.0 g / 100 g fresh weight on the 16th day after the sires grown on the 5th to 16th days From the 16th day
