The starch may be produced from sweet potatoes and potatoes in our country. It is used especially for manufacturing sweets such as glucose, starch sugar, candies, etc. In preparing these, the hydrolysis of starch is achieved either by enzyme or by acid. Industrially the crude starch is frequently used for this purpose. But its saccharification is rather difficult, and especially so with enzymes. The following is the result of our experiments conecerning this point.The saccharification of starch from sweet potatoes soaked in water for several hours can be performed but quite incompletely. The soaking hardens their tissue in such a degree as it can never be softened even by a long boiling. Especially so when they have been soaked in a dilute acid solution, either organic or inorgonic. Experiments with lactic, acetic, butryric, hydrochloric and sulphuric acid gave the same results. The rate of sacharification cannot be increased even by the purification of the crude starch.
