挤压膨化大米辅料麦汁和啤酒的糖类组分分析

Analysis of Carbohydrate in Wort and Beer from Extruded Rice as Adjunct

用液相色谱技术对挤压膨化大米啤酒辅料对应的麦汁、啤酒的糖类组分进行了测定 ,表明 :膨化大米辅料麦汁中麦芽糖含量明显高于未膨化大米辅料麦汁 ,未膨化大米辅料麦汁中葡萄糖、果糖、蔗糖和麦芽三糖的含量均略高于膨化大米辅料麦汁 ,膨化和未膨化大米辅料对应的啤酒中没有检测出果糖、葡萄糖、蔗糖、麦芽糖 ,只检测出微量的麦芽三糖。

The carbohydrates in wort and beer from adjunct of extruded and non-extruded rices respectively were measured by the technology of HPLC. The measurement results indicated that the maltose content of wort from extruded rice was higher than that from non-extruded rice. The contents of glucose, fructose, sucrose, malt trisaccharide in wort and beer form non-extruded rice were higher than that from extruded rice lightly. The glucose, fructose, sucrose, maltose in beer form extruded and non-extruded rice were not found by HPLC. It was found that the malt trisaccharide in beer from extruded and non-extruded rice was less.
