This study aimed to develop a texturally modified soy protein gel that meets the Universal Design Food (UDF) standard, specifically for elderly individuals with dysphagia. To create soft-textured foods, the gel\u2019s texture was modified using transglutaminase at varying concentrations (0.5%, 1.0%, and 2.0%, w\/v) in combination with agar. The soy protein gel prepared with 0.5% transglutaminase exhibited the lowest hardness value (2.2 \u00d7 103 N\/m2) and was classified as Level 4 under the UDF standard, indicating that it requires no chewing and is easy to swallow, making it suitable for individuals with severe dysphagia. In contrast, the gel formulated with 2.0% transglutaminase and 0.5% agar had the highest hardness value (3.29 \u00d7 104 N\/m2) and was classified as Level 2, meaning it can be easily mashed with the gums, making it appropriate for individuals with moderate dysphagia. Structural analyses revealed that modifying with transglutaminase altered the protein\u2019s secondary structure by reducing the content of \u03b1-helixes and \u03b2-sheets while increasing \u03b2-turns, potentially enhancing gel network flexibility. These findings suggest that the combined use of transglutaminase and agar effectively modifies soy protein gel texture to meet the dietary needs of elderly individuals with dysphagia. This approach shows promise for the food industry by providing safer and more diverse food options for aging populations facing dysphagia.<\/jats:p>","DOI":"10.3390\/gels11040303","type":"journal-article","created":{"date-parts":[[2025,4,20]],"date-time":"2025-04-20T20:24:16Z","timestamp":1745180656000},"page":"303","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":14,"title":["Texture-Modified Soy Protein Gels Using Transglutaminase and Agar for Elderly Dysphagia Management"],"prefix":"10.3390","volume":"11","author":[{"given":"Puchcharin","family":"Paleekui","sequence":"first","affiliation":[{"name":"Faculty of Agro-Industry, Chiang Mai University, Chiang Mai 50100, Thailand"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Benjamard","family":"Rattanamato","sequence":"additional","affiliation":[{"name":"Faculty of Agro-Industry, Chiang Mai University, Chiang Mai 50100, Thailand"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nattapong","family":"Kanha","sequence":"additional","affiliation":[{"name":"Faculty of Agro-Industry, Chiang Mai University, Chiang Mai 50100, Thailand"},{"name":"Office of Research Administration, Chiang Mai University, Chiang Mai 50200, Thailand"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kanyasiri","family":"Rakariyatham","sequence":"additional","affiliation":[{"name":"Faculty of Agro-Industry, Chiang Mai University, Chiang Mai 50100, Thailand"},{"name":"Cluster of High Value Products from Thai Rice and Plants for Health, Chiang Mai University, Chiang Mai 50200, Thailand"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5058-2956","authenticated-orcid":false,"given":"Wannaporn","family":"Klangpetch","sequence":"additional","affiliation":[{"name":"Faculty of Agro-Industry, Chiang Mai University, Chiang Mai 50100, Thailand"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sukhuntha","family":"Osiriphun","sequence":"additional","affiliation":[{"name":"Faculty of Agro-Industry, Chiang Mai University, Chiang Mai 50100, Thailand"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Thunnop","family":"Laokuldilok","sequence":"additional","affiliation":[{"name":"Faculty of Agro-Industry, Chiang Mai University, Chiang Mai 50100, Thailand"},{"name":"Cluster of High Value Products from Thai Rice and Plants for Health, Chiang Mai University, Chiang Mai 50200, Thailand"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2025,4,20]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"57","DOI":"10.1016\/j.foodqual.2017.08.009","article-title":"Oral comfort: A new concept to understand elderly people\u2019s expectations in terms of food sensory characteristics","volume":"70","author":"Septier","year":"2018","journal-title":"Food Qual.
