This study compared SDF extracted from untreated, ultra-high-pressure (UHP)-pretreated, cellulase-pretreated, and sequentially UHP\u2013cellulase-pretreated perilla seed hulls and evaluated their structural, physicochemical, and dough-modifying properties. The combined treatment increased the SDF content of the hull material from 3.71% to 8.63% and decreased insoluble dietary fiber from 55.74% to 50.37%. Relative to untreated SDF, the resulting UCPSDF had a lower apparent molecular weight (2442 vs. 2788 Da), a smaller mean particle size (2.76 vs. 3.62 \u03bcm), a lower glucose proportion, and higher arabinose and acidic monosaccharide proportions. FTIR, XRD, SEM, and thermal analyses indicated retention of the principal polysaccharide and cellulose-I signatures, accompanied by changes in structural characteristics and a looser, more porous morphology. UCPSDF also showed the highest water-holding and swelling capacities. At 6% supplementation, UCPSDF produced the strongest elastic response in wheat\u2013corn composite dough, significantly increased springiness (0.59\u20130.72) and cohesiveness (0.64\u20130.76), increased the combined amide I-derived \u03b1-helix and \u03b2-sheet proportion of dough proteins from 53.93% to 66.82%, and reduced the T23 relaxation time from 297.86 to 81.23 ms. These findings indicate that sequential UHP\u2013cellulase pretreatment improves the measured SDF content and hydration functionality of perilla seed hull SDF and supports its use as a dough-structuring ingredient in wheat\u2013corn composite foods.<\/jats:p>","DOI":"10.3390\/foods15183180","type":"journal-article","created":{"date-parts":[[2026,9,8]],"date-time":"2026-09-08T16:46:04Z","timestamp":1788885964000},"page":"3180","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Effects of Ultra-High Pressure\u2013Cellulase Pretreatment on the Structural Characteristics and Functional Properties of Soluble Dietary Fiber from Perilla Seed Hulls and Its Application in Wheat\u2013Corn Composite Dough"],"prefix":"10.3390","volume":"15","author":[{"given":"Fengchen","family":"Zhou","sequence":"first","affiliation":[{"name":"College of Food Science and Engineering, Changchun University, Changchun 130022, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0005-7053-4002","authenticated-orcid":false,"given":"Bo","family":"Wang","sequence":"additional","affiliation":[{"name":"College of Food Science and Engineering, Changchun University, Changchun 130022, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kai","family":"Liu","sequence":"additional","affiliation":[{"name":"College of Food Science and Engineering, Changchun University, Changchun 130022, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yue","family":"Yang","sequence":"additional","affiliation":[{"name":"College of Food Science and Engineering, Changchun University, Changchun 130022, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Qingbo","family":"Wang","sequence":"additional","affiliation":[{"name":"College of Food Science and Engineering, Changchun University, Changchun 130022, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sheng","family":"Li","sequence":"additional","affiliation":[{"name":"College of Food Science and Engineering, Changchun University, Changchun 130022, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2026,9,8]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"4639","DOI":"10.1002\/fsn3.2421","article-title":"Variations on gut health and energy metabolism in pigs and humans by intake of different dietary fibers","volume":"9","author":"Yang","year":"2021","journal-title":"Food Sci.
