Despite being considered a climate-resilient crop, sorghum is still underutilized in food processing because of the limited starch and protein functionality. For this reason, the objective of this study was to investigate the effect of sprouting time on sorghum functional properties and the possibility to exploit sprouted sorghum in bread making. In this context, red sorghum was sprouted for 24, 36, 48, 72, and 96 h at 27 °C. Sprouting time did not strongly affect the sorghum composition in terms of total starch, fiber, and protein contents. On the other hand, the developed proteolytic activity had a positive effect on oil-absorption capacity, pasting, and gelation properties. Conversely, the increased α-amylase activity in sprouted samples (≥36 h) altered starch functionality. As regards sorghum-enriched bread, the blends containing 48 h-sprouted sorghum showed high specific volume and low crumb firmness. In addition, enrichment in sprouted sorghum increased both the in vitro protein digestibility and the slowly digestible starch fraction of bread. Overall, this study showed that 48 h-sprouted sorghum enhanced the bread-making performance of wheat-based products.

AbstractThe aim of the work was to assess the influence of the leavening agent on several technological, chemical, and nutritional characteristics of breads prepared with whole soft wheat (Triticum aestivum L.) flours. As leavening agents in bread-making, baker’s yeast, biga, and sourdough were utilized. Two ancient varieties, Andriolo and Verna, and a modern grain variety, Bologna, were used. Analysis of the obtained breads included the measurement of the phenols content, the antioxidant activity, the in vitro protein and total digestibility, the texture profile, the crumb grain characteristics and the microbial shelf-life test. The results of the principle component analysis of bread features indicated a clustering depending especially on the leavening agent rather than on the employed flour, particularly when sourdough was used. Protein digestibility, crumb grain characteristics, and shelf-life led to the main differences among the samples. Ancient wheat flour displayed similar features when the same leavening agent was applied. Particularly, the use of sourdough levelled the differences due to flour, leading to breads with similar technological and nutritional characteristics. The findings highlighted a marked effect of the leavening agent on bread final characteristics.

Newly developed Bambara groundnut (Vigna subterranea L.) seeds (Accessions No: TVSU 5 – Bambara Groundnut White (BGW) and TVSU 146 – Bambara Groundnut Brown (BGB)) were collected from International Institute of Tropical Agriculture (IITA), Nigeria, planted and harvested. The effects of processing methods (soaking and boiling) on anti-nutritional factors and oligosaccharides content and protein digestibility of BGW and BGB compared with Bambara groundnut commercial (BGC) seeds were investigated. Soaking and boiling significantly reduced the anti-nutritional factors of the samples and the effect increased as processing time was elongated. Sample BGC had lower anti-nutritional factors than BGW and BGB after soaking for 48 h. Tannin contents of the samples were reduced drastically by 99 % throughout the soaking periods. Greatest loss in raffinose level was observed in BGB (59%) and BGW (50%) after boiling for 60 min compared with BGC (43%). The loss in stachyose content of the samples varies with processing and BGC (59%) had greatest loss after boiling for 60 min while soaking for 48 h reduced that of BGB and BGW by 57 and 35%, respectively. Boiling for 60 min increased the in vitro protein digestibility of BGB (89.34 %) compared with BGW (87.48%) and BGC (82.89%). Overall, the results demonstrated that soaking and boiling of newly developed Bambara groundnut seeds could improve the nutritive quality of the seeds.
