    • PROBLEM TO BE SOLVED: To provide a method for producing a highly purified acid type sophorolipid-containing material substantially not containing acetic acid.SOLUTION: The method comprises the steps of (i) and (ii-b): (i) adjusting pH of crude acid type sophorolipid (SL)-containing material to an acidic region lower than 7; and (ii-b) leaving standing still the acidified crude acid type SL-containing material obtained in the step (i) under a low temperature condition determined as in the following conditions (a) - (d) according to its pH, and then washing the generated gelled material with a cold, water-containing solvent of 15°C or lower to obtain gelatinous acid type SL-containing material. The conditions are:(a) pH4 or lower: -25°C-15°C; (b) higher than pH4 and not higher than pH5: -25°C-10°C; (c) higher than pH5 and not higher than pH6: -25°C--10°C; and (d) higher than pH6 and lower than pH7: -25°C--20°C.
    • 要解决的问题:提供一种生产基本上不含乙酸的高纯度酸型含萜油脂的材料的方法。溶液:该方法包括以下步骤:(i)和(ii-b):(i)调节pH 粗酸型含堇油(SL)的材料至低于7的酸性区域; 和(ii-b)在根据其pH在如下条件(a) - (d)测定的低温条件下静置步骤(i)中获得的酸化的粗酸型含SL物质,然后 用15℃或更低的含冷水溶剂洗涤生成的胶凝材料,得到含凝胶酸型SL的材料。 条件是:(a)pH4或更低:-25℃-15℃; (b)高于pH4且不高于pH5:-25℃-10℃; (c)高于pH5且不高于pH6:-25℃-10℃; 和(d)高于pH6并低于pH7:-25℃-20℃。
