Superior bread-making quality is required before breeding lines can be commercially classified. In South Africa, breeding lines together with a quality standard from five environments must be submitted for quality analysis for three consecutive seasons before such lines can be classified for commercial use. Breeders depend on falling number and mixograph analysis to indicate which breeding lines must be selected for submission. Time availability determines whether whole flour or white flour will be used for this quick screening process. During the classification process, the lines have to adhere to 11 primary quality criteria, which include hectolitre mass, falling number, grain and flour protein content, flour yield, flour colour, farinograph water absorption, alveograph stability/distensibility ratio, alveograph dough strength, loaf volume and corrected loaf volume. The aim of this study was to compare flour obtained from three different milling procedures, by using six selected Mixsmart parameters as indicators of the primary classification criteria for commercial cultivar release, to determine whether faster milling procedures such as a hammer mill or Junior Quadrumat mill will give the same results as the currently used Buhler mill. Seed of ten genotypes from two environments was used. There were sufficient correlations between the Mixsmart parameters and primary quality criteria, for selection of the best potential breeding lines, whether whole flour, white flour from the Junior Quadrumat mill or flour from the Buhler mill was used. Linear discriminant analysis confirmed that no differences existed between the three milling procedures for mixograph analysis as indicator of quality.

不同碾磨工艺对硬红面包小麦面团混合参数的影响

在育种品系进行商业分类之前，需要具备卓越的面包制作质量。在南非，必须连续三个季节提交育种品系以及来自五个环境的质量标准进行质量分析，然后才能将这些品系分类用于商业用途。育种者依靠下降数量和混合图分析来表明必须选择哪些育种品系进行提交。时间可用性决定了该快速筛选过程将使用全面粉还是白面粉。在分类过程中，生产线必须遵守 11 项主要质量标准，包括百升质量、下降数、谷物和面粉蛋白质含量、出粉率、面粉颜色、粉质仪吸水率、气泡仪稳定性/膨胀率、气泡仪面团强度、面包体积和修正后的面包体积。本研究的目的是通过使用六个选定的 Mixsmart 参数作为商业品种发布的主要分类标准的指标，比较从三种不同碾磨程序中获得的面粉，以确定更快的碾磨程序（如锤磨机或 Junior Quadrumat 碾磨机）给出与当前使用的布勒磨机相同的结果。使用了来自两种环境的十种基因型的种子。Mixsmart 参数和主要质量标准之间存在足够的相关性，无论是使用全粉、Junior Quadrumat 磨坊的白面粉还是布勒磨坊的面粉，都可以选择最佳的潜在育种线。
