To optimize the milling process, new passages with a stack of fine mesh sieves are used. The UFF extracted from both break and reduction passages exhibits a wide range of functionality and physicochemical characteristics, were incorporated into five reconstituted flour blends. By splitting of UFF fraction isolated from primary passages, the quality of baked bread can be modified manually without using any enzymes or chemical improvers. Substituting the default milling stream with 60% of primary UFF increases the availability of starch for gelatinization by shifting the peak temperature to a higher number. This creates stronger starch-gluten network exhibiting increased elasticity. Raised viscoelasticity and hence water absorption value result in higher loaf volume. The infrared spectroscopy analysis revealed a specific peak at 1659 cm<sup>−1</sup>, associated with water absorption in the amorphous region of starches, which was recorded as the highest intensity for UFF reduction samples. These results were in agreement with imposing a higher starch damage. Furthermore, structural amorphization was also observed based on a broader shallow XRD curve for samples incorporated with UFF of reduction passages due to higher grinding strength generated through the smooth rolls. The lowest polydispersity index content was calculated for break UFF samples and more uniformity in particle size distribution was found. This finding highlighted the effective role of corrugated rolls for producing the certain range of flour granulation.</div></div>","PeriodicalId":15285,"journal":{"name":"Journal of Cereal Science","volume":"120 ","pages":"Article 104058"},"PeriodicalIF":3.9,"publicationDate":"2024-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142653234","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

At a radiation dose of 2 kGy, both protein and carbohydrate content increased; however, they declined at higher doses. The ash content depicted a reduction with increased doses of radiation. Micronutrient composition remained largely unaffected by the irradiation process. Gamma irradiation also influenced cooking quality: water uptake ratio increased, while the optimum cooking time decreased at higher doses. Additionally, an upsurge of amylose content was demonstrated with increasing radiation levels, resulting in softer cooked rice. Thus, it can be attributed that dual processing of rice can effectively modify starch properties, rendering it a viable method for enhancing the textural and functional qualities.</div></div>","PeriodicalId":15285,"journal":{"name":"Journal of Cereal Science","volume":"120 ","pages":"Article 104061"},"PeriodicalIF":3.9,"publicationDate":"2024-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142653174","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Optimal germination periods of 6–18 h significantly improved flour functionality, evidenced by increased Gluten Performance Index, gluten index, and enhanced dough mixing properties. Further, mini-breads, developed after optimizing breadmaking conditions, displayed increased 2D areas in 24 and 36 h and lower crumb hardness in 24 and 36 h of germinated bread compared to those obtained with sound wheat flour. Significant correlations were found among alpha-amylase activity, Falling number, total and damaged starch content, RVA parameters, gelatinization enthalpy, and breadcrumb texture parameters.
