Technological Potential of Saratov Spring Durum Wheat Grain

Abstract

Introduction. Durum wheat is vital for high-quality pasta production. The present research tested the high technological potential of durum wheat varieties developed in the Saratov region. The research objective was to study the effect of the quality of durum wheat on the quality of pasta. Study objects and methods. The study featured durum wheat of the following varieties: Saratovskaya Zolotistaya, Valentina, Nik, Krasnokutka 13, Luch 25, Pamyati Vasilchuka, Bezenchukskaya 182 and Annushka. The experiment involved an original PSL-13 press for standard spaghetti with a diameter of 1.8 mm. The content of protein, raw gluten, and their quality were determined by standard methods. The cooking properties of the pasta were evaluated according to the method developed in the South-Eastern Federal Agricultural Research Center. Results and discussion. The indicators of raw gluten and protein are known to correlate. The samples of Saratovskaya Zolotistaya and Luch 25 had a high protein content of 15.3 and 15.6%, respectively, as well as a high content of raw gluten (33.2 and 35.1%, respectively). The raw gluten of Saratov varieties proved to be much better than in the control samples. The indicator of microSDs sedimentation was 30–36 mm. The strength of spaghetti followed the increase in crude gluten (33–35%) and protein (15.3–15.6%), which is typical of this type of pasta. The strength, coefficient of determination (R2 = 0.98), and sharing force (R2 = 0.92) depended on the protein content. Conclusion. The study established the following optimal selection criteria for durum wheat varieties to be used in strong spaghetti production: virtuosity – 80%, raw gluten – 33–35%, protein content – 5–7% higher than normal, raw gluten – 72–80 units.
