The present invention relates to a process for manufacture of erythritol juice powder with low calorie. Primarily, erythritol can be heated and dissolved first, and then mix with condensed juice in a proper ratio. The mixture can be stirred into powders after cooling to become crystallized. Due to the property of no moisture absorption for erythritol in nature, it can be mixed with juice only after dissolving and reduce to become crystallized. At last, the erythritol juice powder can be obtained with a drying treatment under a low temperature.本發明係有關於一種低熱量的赤藻糖醇果汁粉製造方法,係將加熱溶解之赤藻糖醇與濃縮之果汁以適當之比例混合,待冷卻結晶後將之攪拌成粉末狀,因赤藻糖醇本身有不吸濕之特性,所以必須溶解還原後成結晶狀才能與果汁結合;最後經低溫乾燥流程即可得赤藻糖醇果汁粉。
