异麦芽低聚糖生产新工艺的研究

A Study on a New Way to Produce IsoMaltooligosaccharides

研究了酶法生产异麦芽低聚糖的新工艺，并对影响工艺的主要因素进行了分析。结果表明，采用１３０～１４０ｋＰａ压力的热蒸汽处理淀粉浆后，在９５℃下加酶维持３０～６０ｍｉｎ；采用多酶协同作用糖化工艺，在５８℃和ｐＨ５６条件下反应４０ｈ，异麦芽低聚糖的含量可达５７６％。这也是淀粉（碎米）深加工的有效途径之一。

A new way to produce isomaltooligosaccharides was studied by means of enzymatical hydrolysis. The main factors affecting process were also analyzed. The result showed that the srarch slurry should be treated by steam of 130～140 kPa and then maintained for 30～60 min after adding enzyme at 95℃.With multienzymatical saccharification, the reaction time was 40 h under the condition of 58℃ and pH5.6. The content of isomaltooligosaccharides was 57.6%. This also is an effective way for further processing of starch (broken rice).
