Abstract Physical, sensory and antioxidant properties of wheat bread enriched with sumac flour (SF) with normal and reduced amounts of salt were investigated. SF was added to replace wheat flour at a proportion of 1, 2, 3, 4 and 5 g/100 g. Furthermore, the breads were prepared with normal and reduced amounts of salt (1.5 and 0.5 g/100 g, respectively). The incorporation of SF led to a decrease in bread volume and an increase in crumb hardness, especially when it was added in an amount of more than 2 g/100 g. Salt reduction did not negatively influence these parameters. The addition of SF caused a decrease in lightness and yellowness of crumb, but an increase in redness. SF enriched the wheat bread with phenolic compounds. Hence, the total phenolics content increased with the increase in SF from 5.4 to 15.2 mg gallic acid equivalent per 100 g of dry mass. This in turn led to an increase in the antioxidant capacity. The sensory evaluation indicated that salt reduction did not negatively influence bread quality when SF was added to wheat flour. Regarding the bread quality, the addition of SF should not exceed 3 g/100 g.

Durum wheat is widespread in the Mediterranean area, mainly in southern Italy, where traditional durum wheat breadmaking is consolidated. Bread is often prepared by adding a lot of salt to the dough. However, evidence suggests that excessive salt in a diet is a disease risk factor. The aim of this work is to study the effect of a natural low-sodium sea salt (Saltwell®) on bread-quality parameters and shelf-life. Bread samples were prepared using different levels of traditional sea salt and Saltw...

Abstract In this work, the chemical and physical profile of 5 different bread types (Multicereal bread, Bavaria wheat bread, Wholemeal bread, Rye and Oat bread) were analysed in depth, namely the nutritional profile, individual fatty acids and soluble sugars through GC-FID and HPLC-RI, respectively, as well as the mineral profile, including micro and macroelements. Furthermore, a texture profile analysis was carried out in addition to the measurement of the crust colour. Each bread type showed a...

Flour from old varieties are usually considered very weak flours, and thus difficult to use in breadmaking especially when processed as Italian “Tipo 2” flour. Hence, the aim of our study was to understand if agronomic treatments can be used to improve flour processability and the quality of three old wheat varieties. An experimental strip-plot scheme was used: three old wheat varieties (Andriolo, Sieve, Verna), two seeding densities, three levels of nitrogen fertilization (N35, N80, and N135), ...

Abstract Background Syrian Sumac, scientifically defined as Rhus coriaria, is a commonly used spice powder in the Middle East. Rhus coriaria has been shown to contain numerous compounds that have a substantial role in the food industry and in homeopathic therapy. From the retardation of oxidative processes to the treatment of fungal and bacterial infections and many more, these compounds are of great importance in improving human health and economy. Scope and approach Several studies have been d...

Abstract Bread is one of the most popular foods worldwide. Aerial parts of sweet potato (SP) are rich in dietary fiber and phytochemicals. The SP powder (cv. Simon No.1) was used to substitute 5%, 10%, and 15% (w/w) of flour to produce breads. Crude protein, fat, ash and dietary fiber of SP powder were higher than those of flour. Total phenols, caffeoylquinic acid derivatives and antioxidant properties of SP were higher than those of flour. Crude protein, fat, ash, h, ΔE values, hardness, gummin...

Abstract The efficacy of two sodium reduction strategies in preserving sensory profile and consumer liking of yeasted wheat bread was tested, by combining sensory data, aroma compounds and consumer investigations. The use of (i) a reduced-sodium salt substitute, Pansalt® (NaCl 57%, other salts and minor ingredients) at 1.5%, and (ii) the heterogeneous NaCl distribution (average level of 1%) leading to enhanced saltiness by taste contrast, were compared with standard (1.5%) and reduced (1.0%) add...

Abstract Sumac (Rhus coriaria L.) is a medicinal plant distributed worldwide for its health benefits and its culinary uses as a flavoring agent. The aim of the current study was to detect chemical characterization of Iranian sumac populations. A high degree of variation was found in the chemical characteristics and the results revealed significant differences among the accessions. Titratable acidity varied from 2.01 to 7.84%, while the pH ranged from 2.66 to 3.90. Ascorbic acid ranged from 10.00...

In the Mediterranean area, being pedoclimatic conditions more favorable to durum than common wheat cultivation, a bread-making tradition from durum wheat has been established. Durum wheat bread has a compact texture, with lower specific volume than common wheat bread. Due to health implications, several studies were carried out to reduce the content of NaCl in common wheat bread, however without considering durum wheat bread. The aim of this work was to assess the effect of salt reduction on qua...

The aim of this study was to characterize wheat cookies enriched with 0.5% and 1.0% of Hypericum perforatum L. (St. John’s wort, SJW) and determine their pro-health properties in vitro after hydrolysis in simulated gastrointestinal conditions. The results indicated that 1.0 SJW was characterized by the highest content of polyphenols, flavonoids, and phenolic acids (2.32 mg mL−1, 4.93 µg mL−1, and 12.35 µg mL−1, respectively). The enriching cookies had no effect on water absorption capacity (WAC)...

Abstract The primary objectives of this study were to investigate the quality of no-salt wheat bread prepared with a mixture of herbs (MH) using a method involving the addition of scalded flour and to compare this method to the traditional single-phase method. In the case of the single-phase method, MH (thyme, lemon balm, and nettle (1:1:1)) was added in the form of dried herbs at a level ranging from 3% to 12% (every 3%) to the dough, whereas in the case of scalded flour, MH was added as an inf...
