This study evaluated the effect of wheat flour substituted by buckwheat flour on dough rheology and bread quality over the staling process. Wheat flour was replaced by 0%, 10%, 20% and 30% of buckwheat flour and the resulting dough mixing properties, viscosity profile, gel texture, rheology behaviour and extensibility properties were analysed. Internal bread structure (C-Cell and confocal microscopy), specific volume, density and crumb texture profile were also assessed. The increase in buckwheat level gradually decreased flour water absorption (p &lt; 0.05), dough stability and development time, with increased gluten weakening as evidenced by decreased C2 values (protein strength) of Mixolab. As a result, the dough was less resistant to extension, with decreased extensibility. The highest viscosity profile of the starch paste was observed with 30% buckwheat inclusion level, which may lead to faster bread staling process. A solid-like and elastic behaviour was observed in the rheology evaluation, suggesting an interaction between fibre and starch from buckwheat with gluten proteins. Although changes in dough rheology occurred, the bread quality remained unchanged at levels of up to 20% buckwheat level (p &gt; 0.05), with similar specific volume, density, internal structure and texture profile compared to the control bread (0% buckwheat). In conclusion, buckwheat was found to be a viable wheat flour substitute with only minimal changes in dough behaviour and maintenance of bread technological quality, while enhancing the </span></span>nutritional profile<span> by increasing fibre content and total essential amino acid.</span></span></p></div>","PeriodicalId":48640,"journal":{"name":"Food Structure-Netherlands","volume":"39 ","pages":"Article 100364"},"PeriodicalIF":4.7,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139070852","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This work critically reviews current techniques used to study multiscale food matrix structures in animal-origin meats and plant-based meats and considers their application in the engineering of hybrid cell-based meat food matrices. Currently, research focusses on cell-line development, media composition, tissue functionality, and food matrix properties of scaffolds, hydrogels, and non-animal derived proteins to use in hybrid cell-based meat products. However, the interactions between plant-protein and animal-origin cells within hybrid cell-based meats have not been studied but are key to forming novel overall food matrices. We will need to adapt techniques from adjacent fields to characterise and achieve sensory equivalence of animal-origin meat products.

In contrast, the presence of charged polysaccharides led to an increase in protein domain size, a decrease in pore fraction, and a decrease in elastic and viscous moduli.

However, the pea milling process is of paramount importance and can affect the final flour quality. This study aims to evaluate the influence of different milling processes of Irish-grown peas on flour composition, spectral profile (Near Infrared - NIR), pasting properties and dough rheology. Three mills were used: roller (RM), hammer (HM) and cutting (CM) producing RM, HM and CM flours, respectively. A commercial strong wheat flour was used as the base flour. For producing doughs, wheat flour was blended with each pea flour at a 15:85 (pea: wheat).

SEM demonstrated that higher particle sizes obtained from the CM tended to have larger starch and protein matrix aggregates. Pea flour from the RM presented the highest viscosity profile and hardness, most likely due to the higher starch and lower total dietary fibre content. The lower pasting viscosity profile of pea flour obtained from CM is most likely due to a high level of damaged starch present in this flour. There were no significant differences found among WT and flour blends for gel hardness. This may imply that the incorporation of 15 % HM and CM flours perhaps will not impact the staling process of the final bread products.
