The present invention provides a process for production of a solid material containing isomaltulose crystals and trehalulose comprising the process steps A) bringing an enzyme complex which is able to catalyse the reaction of sucrose to isomaltulose and trehalulose into contact with a sucrose-containing solution； B) isomerizing at least some of the sucrose to isomaltulose and trehalulose； C) separating off the enzyme complex to give a solution containing isomaltulose, trehalulose and water； D) partial removal of the water by evaporation, while obtaining a concentrated solution with, based on the total solution, a solid content of 75 wt% to 95 wt%, preferably 80 wt% to 93 wt%, particularly preferably 86 wt% to 92 wt%； E) bringing the concentrated solution to a temperature of 30 °C to 63 °C, preferably 45 °C to 62 °C, even more preferably 55 °C to 60°C, and subsequent induction of isomaltulose crystallisation in this temperature range followed by cooling while obtaining a solid material containing isomaltulose crystals and trehalulose.本發明提供製造含有異麥芽酮糖晶體和海藻酮糖之固體物料之方法，該方法包含下列製程步驟： A) 令能夠催化蔗糖轉化成異麥芽酮糖和海藻酮糖之反應的酶複合物與含有蔗糖之溶液接觸； B) 使至少一些該蔗糖異構化成異麥芽酮糖和海藻酮糖； C) 分離該酶複合物以產生含有異麥芽酮糖、海藻酮糖和水之溶液； D) 藉由蒸發除去部分水並同時獲得固體含量為75重量(wt)%至95 wt%，較佳為80 wt%至93 wt%，特佳為86 wt%至92 wt%(基於該全部溶液)之濃縮溶液； E) 令該濃縮溶液之溫度達到30℃至63℃，較佳為45℃至62℃，再更佳為55℃至60℃，接著在此溫度範圍內引起異麥芽酮糖結晶化，隨後冷卻並同時獲得含有異麥芽酮糖晶體和海藻酮糖之固體物料。
