通过几年来运用赤霉酸制麦实践,作者总结了先低温,后高温的浸麦、发芽工艺,从而制麦周期缩短2~3天,各项麦芽指标优于不加赤霉酸的麦芽。因此,有显著的经济效益。(陆月雪) 相似文献

一种新开发的方法用于模拟大麦在浸麦及浸麦后的发芽情况,这一方法是基于实验室中采用不同浸麦程序,不同的湿浸和断水时间,不同温度、水敏感性以及不同的发芽方法,这一模型可以用于分析浸麦及发芽,以设计浸麦工艺来生产均一性的麦芽。 相似文献

法麦Vanessa是优质的啤酒大麦,但该品种大麦不同于国麦和其它进口大麦,制成的麦芽通常粘度和葡聚糖较高,因此,制麦时要根据大麦特性适时制定相应工艺,才能获得优质麦芽。 相似文献

选用进口大麦Gairdner和国产大麦甘啤二号,分析比较了两种大麦发芽过程中赤霉素、生长素和脱落酸等内源激素含量的变化。结果表明,3种激素在两种大麦发芽过程中均呈现出随发芽时间上下波动的趋势,且两种大麦在发芽过程中各激素含量的变化规律基本一致,同时探讨促进生长激素和抑制生长激素的比例对大麦发芽过程中蛋白酶活力的影响。实验结果表明,随着促进生长激素和抑制生长激素比例的升高,两种大麦发芽时蛋白酶活力均有较大幅度的增长,加速了大麦发芽过程中醇溶蛋白含量的降低及热稳定蛋白的释放。 相似文献

In many instances brewhouse performance cannot be predicted from a finished malt specification. This is particularly so for factors such as lautering, yeast performance, filtration and head character. There are two aspects involved in improving the brewing performance of malt. Firstly, an understanding of the malt characteristics affecting particular aspects of the brewing process and secondly an understanding of how the malting process affects or can be controlled to optimise these characteristics and thus their performance. In this work the relationship between barley variety, steeping pattern, malt quality and brewing performance is investigated. Six different barley varieties were micromalted in a Seeger micromalting unit under four different steeping regimes. Sub-samples were taken at intervals during steeping for enzyme analysis and measurement of water distribution. Following steeping, the samples were germinated and kilned using standard micromalting conditions. Finished malts were analysed by standard EBC methods for routine malt quality parameters including apparent attenuation limit. Worts were tested for total β-glucan content, β-glucan molecular weight distribution, filter plugging potential and carbohydrate levels. A sub set of malt samples were then micro-brewed and tested for β-glucan molecular weight (MW) distribution, beer filterability and foam stability. 相似文献

实验结果表明 :添加发芽大麦粉或不发芽大麦粉 ,能增加麦片中钙、磷、铁的含量 ,而焙烤温度对麦片钙、磷、铁含量的影响不大。添加发芽大麦粉和不发芽大麦粉可增加麦片中可溶性蛋白的含量 ,而且在同一焙烤温度下 ,添加量越大 ,可溶性蛋白含量越高。焙烤温度对可溶性蛋白含量的变化也有明显的影响 ,随着焙烤温度的上升 ,可溶性蛋白含量增加。添加发芽大麦粉和不发芽大麦粉能提高麦片还原糖的含量。焙烤温度对还原糖也有一定的影响 ,即随温度的上升 ,其含量呈现下降的趋势。添加发芽大麦粉能增加麦片VB1的含量。焙烤温度对VB1的影响较大 ,随着焙烤温度的升高 ,VB1的损失增加 相似文献
