Continuous Production of Maltulose from Maltose in a Pressurized Hot Phosphate Buffer

2022 Japan Journal of Food Engineering  
A flow-type reactor was constructed to mass-produce maltulose from maltose dissolved in 10 mmol/L phosphate buf fer, pH 7, which was maintained in a liquid state under subcritical water conditions. The reactor was then used to examine the ef fects 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.
