加拿大新啤酒大麦AC Metcarlfe的性能研究

Study on the Properties of New Canadian Beer Barley-AC Metcarlfe

ACMetcarlfe大麦原料千粒重40.86g、水分11.05％、发芽力99％、发芽率100％、水敏性5％、蛋白质11.82％。经小试、大生产试验和酿造试验结果表明,加拿大AC Metcarlfe大麦具有无休眠期。蛋白质含量适中、吸水快、萌芽率高,大麦麦芽的糖化力及浸出物含量均高,β-葡聚糖含量较低。酿造特性:糖化时间较短;降糖快及双乙酰还原性好;试验啤酒口味较醇厚;试验啤酒的离子和风味物质均正常;TBA和RSV值一般;成品啤酒口味醇厚、抗老化时间较长。（孙悟）

The properties of new Canadian beer barley-AC Metcarlfe were as follows: the weight of 40.86 g/1000 granule, moisture content 11.05%, germinating capacity 99%, germination rate 100%, water enzyme 5%, and protein content 11.82%. The small-scale production tests, the large-scale production tests and the brewing tests indicated that AC Metcarlfe possessed the foDowing prop-erties in production-no dormant period, moderate protein contents, strong water uptake ability, high germination rate, strong sacchari-fication power of barley malt and high extracts contents, and relatively low β-glucosan contents; and the characteristics in brewing were as follows: relatively short saccharification period; quick sugar dropping and good diacetyl reductibility; relatively mild taste of test beer; normal manifestation of ions and flavoring components of test beer; standard TBA and RSV values; pure and mild taste of product beer and relatively long aging resistance period.(Tran. by YUE Yang)
