Abstract | The article presents the study results of the effect of spelt wheat adding to milling blendes of soft wheat grain on the grits-forming ability when milling into flour. Studies have shown that large middligs after I, II, III break systems were most obtained from spelt wheat – 29,0 %, and the least from soft wheat – 23,54%. In composite mixtures, this indicator is the highest in samples 80:20 and 75:25 – 28,68 and 28,41 %, respectively, and the lowest – 85:15. It was found that the highest yield of medium middlings after break systems in soft wheat – 2,63 %. This indicator was the lowest when milling composite mixtures 90:10, 80:20 and 75:25 and in spelt wheat – 0,17 %. The yield of fine middlings after the I, II, III break systems was in the range of 14,5–16,0 %, depending on the experiment variant. The lowest yield of hard dunst was in spelt and soft wheat – 0,03 and 0,05 %, respectively, the highest – in the composite mixtures of 95:5 and 75:25 and was 2,50 and 2,88 %, respectively. The yield of soft dust varied between 13,0 and 20,42 %. Flour yield, depending on the composition of milling blend in samples varied from 5,22 % to 14, 09 %. The lowest flour yield was in soft wheat – 5,22 %, while in spelt wheat – 12,47 %, which is 2,4 times more. In composite mixtures, this figure also varied significantly from 5,98 to 14,09 %. It was found that the extraction of intermediate grits-dunst products of milling is 64,3–72,0 % depending on the experiment variant. Based on the obtained results, it can be concluded that the introduction of 15 % spelt wheat grain into the milling blendes of soft wheat has a positive effect on the formation of grits-dunst products and flour extraction. Further increase in the share of spelt wheat leads to such changes in milling blendes, in which these figures are reduced. | ||
