在冬末春初由于蔬菜缺乏,维生素C的供应往往不足,这个时期部队容易发生营养缺乏病。甘薯中含有丰富的维生素C,是冬春维生素C的极好供给来源。但由于储藏不当,甘薯容易腐坏而不能长期供应。在济南郊区有些生产队用井窖储藏甘薯,可以保存到第二年甘薯收获而损耗变质较少。为协助部队把甘薯保存好,并且观察储藏中维生素C含量的变化情况,我们在市粮食局大力协助下就井窖储藏方法进行了研究,并对储藏当中窖内温度变化、甘薯的维生素C含量变化等做了四个多月的观察,初步获得了一些材料,总结介绍如下。
Due to the lack of vegetables in the late winter and early spring, the supply of vitamin C is often inadequate. During this period, the armed forces are prone to nutritional deficiency. Sweet potato is rich in vitamin C, winter vitamin C is an excellent source of supply. However, due to improper storage, sweet potato perishable and can not be long-term supply. Some production teams in the suburbs of Jinan use well cellars to store sweet potatoes, which can be stored for the second year with less loss and deterioration. In order to assist the unit to conserve the sweet potato and observe the change of the content of vitamin C in the storage, we conducted a study on the storage method of well cellar with the help of the Municipal Bureau of Grain, and analyzed the change of temperature inside the cellar, the vitamin C content of sweet potato Changes made more than four months of observation, preliminary obtained some materials, summarized as follows.
