“…The quality of the crops is also greatly influenced by the nitrogen rate of the fertilization. Concretely, N deficiency may cause important defects in the plant at the molecular level, which—particularly for durum wheat—affect the protein content and composition of the grain, directly linked to the development of hard vitreous kernels [ 41 ]. These parameters are indeed the most relevant indicators of the quality of the semolina extracted from the grains for pasta elaboration [ 42 , 43 ].…”

Nanotechnology is emerging as a very promising tool towards more efficient and sustainable practices in agriculture. In this work, we propose the use of non-toxic calcium phosphate nanoparticles doped with urea (U-ACP) for the fertilization of Triticum durum plants. U-ACP nanoparticles present very similar morphology, structure, and composition than the amorphous precursor of bone mineral, but contain a considerable amount of nitrogen as adsorbed urea (up to ca. 6 wt % urea). Tests on Triticum durum plants indicated that yields and quality of the crops treated with the nanoparticles at reduced nitrogen dosages (by 40%) were unaltered in comparison to positive control plants, which were given the minimum N dosages to obtain the highest values of yield and quality in fields. In addition, optical microscopy inspections showed that Alizarin Red S stained nanoparticles were able to penetrate through the epidermis of the roots or the stomata of the leaves. We observed that the uptake through the roots occurs much faster than through the leaves (1 h vs. 2 days, respectively). Our results highlight the potential of engineering nanoparticles to provide a considerable efficiency of nitrogen uptake by durum wheat and open the door to design more sustainable practices for the fertilization of wheat in fields.

“…1 CWAD composite. This is due to the differences in the level of HVK and test weight between the two composites (Dexter, Williams, Edwards, & Martin, ; Fu, Wang, Dupuis, Taylor, & Nam, ). On the other hand, due to the gradual decrease in the bran‐rich fraction with the increase in top screen opening, SY2 and FY2 from QJ flour mill (B4–6) decreased from 30% to 9% and 14% to 4%, respectively.…”

Background and objectives:Effective and efficient selection of key quality traits is crucial to develop new durum varieties with improved end-use quality. This study was undertaken to develop a rapid micromilling protocol using a single Brabender Quadrumat Jr. (QJ) semolina mill without purification to predict milling performance and generate semolina for quality analysis. Findings: After grinding 200 g of durum wheat with a QJ mill with the reel sifter removed, the resulting wholemeal was sifted through a laboratory sifter equipped with a bottom screen of 180 µm to remove flour and a top screen of 630 µm to retain bran-rich fraction. Semolina materials between the two screens were collected. A model for predicting semolina yield (R 2 = 0.81) was developed based on the amounts of semolina and bran-rich fraction, thus eliminating the need for additional milling to recover semolina in the bran-rich fraction. There were highly significant correlations (r > 0.86) for semolina ash, yellowness, yellow pigment content, protein content, wet gluten, and gluten index between semolina prepared with this proposed protocol and those generated with a Allis-Chalmers mill. Conclusions: The micromilling protocol developed in this study is rapid and reliable for assessing durum milling performance and for preparing semolina for quality characterization. Significance and novelty: The proposed protocol modified QJ mill and optimized milling conditions. A robust and simplified model was developed for predicting semolina yield with one-step milling. It is a useful tool for breeding programs or genetic mapping studies that are usually large in sample number but very limited in sample size.

Although most of the durum wheat produced in the Canadian prairies in 2017 and 2018 met the test weight (TW) requirements for the top grades of Canada Western Amber Durum (CWAD), some samples of top grades were inferior in milling quality. To understand the abnormality, this study was conducted to investigate TW, thousand kernel weight (TKW) and kernel size distribution (KSD) in relation to durum milling potential, semolina composition and pasta quality. With reduction of kernel size, semolina and total milling yields decreased progressively, and kernels passing through no.6 slotted sieve had detrimental impact on milling. The overall relationship between TW and milling yields appeared to be genotype dependent. At similar TW, variety showed lower milling yields had greater proportion of smaller kernels. By account for the difference in KSD, greater relationships (R2 > 0.91, p < 0.001) were found for TKW and proportion of kernels passing No.6 slotted sieve with milling yields than TW (R2 = 0.75, p < 0.001). This infers potential use of small kernels (passing No.6 slotted sieve) as a new objective grading factor for rapid prediction of milling quality of CWAD. Although small kernels exhibited much higher yellow pigment than the larger ones, pasta made from small kernels was duller, redder and less yellow, likely due to the higher semolina ash and protein contents, which adversely affected pasta color.
