以麦芽糖为原料，在10 mmol/L、pH 7的磷酸盐缓冲液中，在亚临界水条件下保持液态，构建了流动式反应器，实现了麦芽糖的批量生产。然后利用该反应器考察了反应温度、平均停留时间和麦芽糖浓度对麦芽糖产量的影响。最佳反应温度为115min(实验范围内最高温度)，平均停留时间为10℃。综合考虑底物利用率和麦芽糖浓度，麦芽糖的最佳浓度为10%(w/v)。
A flow-type reactor was constructed to mass-produce maltulose from maltose dissolved in 10 mmol/L phosphate buffer, pH 7, which was maintained in a liquid state under subcritical water conditions. The reactor was then used to examine the effects of reaction temperature, average residence time, and maltose concentration on the production of maltulose. The optimal conditions were a temperature of 115℃(the highest temperature in the range tested), with an average residence time of 10 min. Considering both substrate utilization efficiency and maltulose concentration, it was concluded that a maltose concentration of 10%(w/v) was optimal.
