Abstract
The utilization of dried powder of sweet potato, which was prepared after the removal of soluble components-a very useful medium for microbes, was investigated for the purpose of complete utilization of sweet potato. 1. The above dried powder was found to be available to a material for alcohol fermentation. 2. The yield of starch from the dried powder increased through the adequate alkali treatment (pH 9.5-11.0), to attain to almost the same yield as that in the usual method from the fresh sweet potato. 3. The quality of the above prepared starch such as in x-ray diffraction and amylography was not so much different from that of control except the slightly higher content of protein and the lower degree in whiteness. Dehydration of sweet potato became four times more rapid by removing the soluble components, and the dried powder could be used to prepare starch even after a year of storage as much as soon after drying. Therefore, if some device is done for the starch to be higher in whiteness, a new process for manufacturing starch from sweet potato might be expected to be designed.
