However, the micro-scale mechanisms governing its impact on dough components remain unclear. This study systematically investigated the physicochemical alterations of starch and gluten in doughs with varying potato pulp/wheat flour ratios. The research findings revealed that an increase in potato pulp content significantly modified both components. For starch, the relative crystallinity decreased (from 25.5% to 16.6%, shifting to a C-type crystalline pattern), while the pasting viscosity increased (from 1780.3 mPa s to 2040.2 mPa s for peak viscosity). Swelling power and solubility reached their peak values at 20% potato pulp substitution. For gluten, the protein structure became less ordered, with α-helix content dropping from 41.4% to 24.2%. Crucially, the disulfide bond content declined, accompanied by a shift from the stable gauche–gauche–gauche conformation (41.46% to 16.91%) to an unstable conformation, weakening the protein network. The samples with a potato pulp content of 20% displayed an optimal balance, characterized by starch with high swelling/solubility and gluten retaining a relatively higher α-helix content (35.62%). The deterioration beyond 20% was attributed to the incompatibility between the dominant potato starch and the diluted, weakened gluten network, as illustrated in the proposed mechanism. This work elucidates the micro-scale interactions in potato-wheat dough, providing a theoretical basis for developing high-quality composite products.</div></div>","PeriodicalId":15285,"journal":{"name":"Journal of Cereal Science","volume":"128 ","pages":"Article 104392"},"PeriodicalIF":3.7,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147397829","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}

Nitrogen synchronization ranged from 10 to 52 % across vetch management treatments, with early sowing combined with late termination accumulating more N than late sowing with early termination. Greater synchrony increased vitreousness and screen retention, and reduced flotation index, but had no effect on test weight. Protein concentration declined with improved synchrony, while starch and oil remained unchanged. On the other hand, N fertilization reduced flotation index, tended to increase screen retention, and raised kernel protein concentration, but had no effect on vitreousness or test weight; while oil and starch responses were inconsistent across seasons.
