Abstract Triticale grain, a wheat-rye hybrid mostly used for animal feed, has been recently reported to exhibit different trends when used as unmalted or malted grain in the brewing industry. The aim of this study was to evaluate the potential of four different triticale lines to evaluate their potential for malt production. The four studied triticale malts PM-1, PM-3, PM-6, and PM-8 lines yielded an extract content higher than 100% and a diastatic power similar to some barley malts (86.19–190.19°L). The produced worts showed a higher percentage of soluble protein, between 4.56% and 5.66%, with a large viscosity value (∼2.055 cP) reported for this raw material. Two triticale malts were selected based on their performance, PM-1 and PM-3, and fermented at different percentage combinations with barley malt (0, 30, 50, 70, and 100%). The results revealed that the use of 100% triticale malt yielded an acceptable fermentation, with an Apparent Attenuation Limit (AAL) of 72%. The optimal triticale-barley malt ratio was 30/70, where supplementing triticale malt enriched the extract, enhancing the fermentation. These results support the suitability and possible establishment of triticale grain as a brewing crop.

黑小麦（X Triticosecale Wittmack）麦芽在啤酒麦汁生产中的潜力

摘要 黑小麦是一种主要用于动物饲料的小麦-黑麦杂交种，最近据报道在酿造工业中用作未发芽或发芽的谷物时表现出不同的趋势。本研究的目的是评估四种不同小黑麦品系的潜力，以评估其麦芽生产潜力。四个研究的小黑麦麦芽 PM-1、PM-3、PM-6 和 PM-8 品系产生的提取物含量高于 100%，并且具有与某些大麦芽相似的糖化能力 (86.19–190.19°L)。生产的麦芽汁显示出更高百分比的可溶性蛋白质，介于 4.56% 和 5.66% 之间，据报道该原材料具有较大的粘度值 (~2.055 cP)。根据性能选择了两种小黑麦麦芽，PM-1 和 PM-3，并与大麦芽按不同百分比组合（0、30、50、70 和 100%）进行发酵。结果表明，使用 100% 小黑麦麦芽产生可接受的发酵，表观衰减极限 (AAL) 为 72%。最佳的小黑麦-大麦麦芽比例为 30/70，其中补充小黑麦麦芽丰富了提取物，增强了发酵。这些结果支持黑小麦作为酿造作物的适宜性和可能建立。
