Purpose. To study the quality formation in bread from different flour of spelt wheat (premium, whole-wheat) depending on the variety and line.
Methods. Laboratory, mathematical and statistical, physical and chemical.
Results. The bread volume made from high-grade flour varied from 303 to 523 cm3, which corresponds to 1.0–7.6 points depending on the variety and line of spelt wheat. The bread volume made from whole-wheat flour was 10–20% less than the bread volume made from premium flour. The average bread volume obtained from whole-wheat flour of ‘Zoria Ukrainy’ variety was 470 cm3, while low bread volume was obtained from flour of ‘Shvedska 1’ variety and LPP 3132, LPP 3117, TV 1100 lines which corresponded to 2.8–3.2 points. In other varieties and lines, these indicators were very low and ranged between 270 and 328 cm3 or less by 142–200 cm3 compared to the standard variety. The convexity of pan bread made from high-grade flour was the highest in ‘Zoria Ukrainy’ spelt wheat variety and NAK 34/12‑2 line: 0.49 and 0.54, respectively, which corresponded to 5.0 points. Significantly higher indicators were found in P 3, NAK34/12–2, and LPP 3122/2 lines: 0.38–0.51 (1.0–5.0 points). In ‘Shvedska 1’ variety and five lines, the indicator of bread convexity varied from 0.27 to 0.37 (from 3.0 to 4.0 points). In other varieties and lines it was significantly lower (0.07–0.21) than in the standard. The indicator of bread convexity from whole-wheat flour in ‘Zoria Ukrainy’ spelt wheat variety was 0.37 which corresponded to 4.0 points. Significantly higher indicators were found in P 3, NAK34/12–2 and LPP 3122/2 lines: 0.38–0.51 (1.0–5.0 points). In ‘Shvedska 1’ variety and five lines, the bread convexity indicator varied from 0.27 to 0.37, that corresponds to 3.0–4.0 points). In other varieties and lines it was significantly lower (0.07–0.21) than in the standard. Culinary quality of bread was high in all samples: 7.2–8.4 points (80–93% of the maximum value). However, the highest quality had the bread made from ‘Zoria Ukrainy’ variety, LPP 3132, NAK34/12–2, and TV 1100 lines. The overall culinary quality of whole-wheat bread was very high as it varied from 8.3 to 9.0 points. However, the bread made from ‘Shvedska 1’ variety and LPP 3117, LPP 3122/2, P 3, LPP 3132, NAK34/12–2 lines had the highest quality (9.0 points).
Conclusions. Gloss index of bread surface and its overall estimate is affected by the protein content in grain. Gluten content has a slightly smaller effect on bread quality. In addition, crust surface, bread texture, the overall estimate of bread quality is also affected by the gluten deformation index. Bread obtained from ‘Zoria Ukrainy’ flour, LPP 3132, NAK34/12–2, and TV 1100 lines had the highest overall culinary evaluation.
