酸法水解玉米芯制备还原糖液及其在烟用反应型香料中的应用

Preparation of Reducing Sugar Solution by Acidic Hydrolyzing Corn Cob and Its Application in Tobacco Reaction Flavor

摘要:

玉米芯中富含木糖和阿拉伯糖,研究表明玉米芯是生产Maillard反应香料前驱体—戊糖的良好原料。以玉米芯为原料,提取得到戊聚糖,运用稀酸水解法获得还原糖液。HPLC-ELSD法测定表明还原糖液富含木糖和阿拉伯糖。将标准化的还原糖液与氨基酸混和后,经Maillard反应获得了不同风味的反应型香料,为反应型香料的生产找到了一种廉价易得的戊糖原料,并为农产品加工废弃物—玉米芯找到了新的利用途径。

Abstract:

Corn cob was one kind of ideal raw materials for processing flavor precursor because of its rich xylose and arabinose.The extracted pentosans were hydrolyzed by diluted acid to obtain reducing sugars hydrolysates.HPLC-ELSD analysis results revealed that xylose and arabinose were rich in the hydrolysates.The standardized solutions of reducing sugars were utilized in the process of different reaction flavors.Therefore,one cheap raw materials of pentose for reaction flavors was developed.
