中文摘要:

      目的 研究燕麦饮品中燕麦酶解后DE值测定方法。方法 样品酶解后利用碘量法测定空白、标准品、样品过量二价铜, 利用计算得出燕麦酶解后DE值的含量。结果 该方法实现在线生产快速检测, 解决了目前检测DE值含量方法GB/T5009.9-2003中存在的以下弊端: 检测耗时长, 操作步骤复杂, 不适于生产的在线检测等。本方法在检测时间上与GB/T5009.9-2003法比较, 缩短检测时间90 min。结论 本方法适合于生产线上在线快速测定。

英文摘要:

      Objective To explore the determination method of oat enzymolysis DE in oat drinks. Methods The sample after enzymatic hydrolysis were determined using iodometric methods on blank, standard, and two samples with excess copper, and the content of DE value was calculated in the oat enzyme solution. Results This method could realize the rapid detection for online production, and avoid the following shortcomings by GB/T50 09.9-2003 in the same detection: time-consuming, complicated operation steps, not suitable for online detection of production, etc. Compared with the GB/T5009.9-2003 method, this method could shorten the detection time by 90 min. Conclusion This method is suitable for the rapid determination of online production.
