Cincau perdu (CP), also known as grass jelly, is a traditional jelly-like dessert popular in Southeast Asia. CP hydrogels could be rapidly prepared by microwave-assisted heating, followed by cooling to room temperature. The rheological properties, stiffness, and syneresis of the hydrogels could be adjusted by changing the hydrogels\u2019 concentration. 3D constructs faithful to the blueprint could be fabricated using inks composed of 10 w\/v% CP hydrogels. The textural properties were tunable by altering the geometry (grid type and height) of the printed construct. The CP hydrogels were categorized as level 5 (minced and moist) criteria based on the International Dysphagia Diet Standardization Initiative (IDDSI), making them suitable for diets of patients with dysphagia. Taken together, these findings demonstrate the potential of CP hydrogels as a sustainable, naturally gelling, and culturally relevant material for 3D-printed diets for patients with dysphagia.<\/jats:p>","DOI":"10.3390\/foods15050960","type":"journal-article","created":{"date-parts":[[2026,3,9]],"date-time":"2026-03-09T17:16:03Z","timestamp":1773076563000},"page":"960","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["3D Printing of Cincau Perdu (Premna oblongifolia) Hydrogel for Dysphagia Patient\u2019s Food Application"],"prefix":"10.3390","volume":"15","author":[{"ORCID":"https:\/\/orcid.org\/0009-0000-0815-4758","authenticated-orcid":false,"given":"Doohan","family":"Taqdissillah","sequence":"first","affiliation":[{"name":"Department of Mechanical Engineering, Faculty of Engineering, Universitas Indonesia, Soemantri Brodjonegoro Street, Kampus UI, Depok 16424, Indonesia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2545-1206","authenticated-orcid":false,"given":"Wildan","family":"Mubarok","sequence":"additional","affiliation":[{"name":"Division of Chemical Engineering, Department of Materials Engineering Science, Graduate School of Engineering Science, The University of Osaka, 1-3 Machikaneyama-cho, Toyonaka 560-8531, Osaka, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6050-4505","authenticated-orcid":false,"given":"Retno Wahyu","family":"Nurhayati","sequence":"additional","affiliation":[{"name":"Department of Chemical Engineering, Faculty of Engineering, Universitas Indonesia, Soemantri Brodjonegoro Street, Kampus UI, Depok 16424, Indonesia"},{"name":"Research Center for Biomedical Engineering, Faculty of Engineering, Universitas Indonesia, Depok 16424, Indonesia"},{"name":"Stem Cells & Tissue Engineering Cluster, Indonesian Medical Education and Research Institute, Faculty of Medicine, Universitas Indonesia, Jakarta 10430, Indonesia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1041-4798","authenticated-orcid":false,"given":"Shinji","family":"Sakai","sequence":"additional","affiliation":[{"name":"Division of Chemical Engineering, Department of Materials Engineering Science, Graduate School of Engineering Science, The University of Osaka, 1-3 Machikaneyama-cho, Toyonaka 560-8531, Osaka, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1541-2118","authenticated-orcid":false,"given":"Yudan","family":"Whulanza","sequence":"additional","affiliation":[{"name":"Department of Mechanical Engineering, Faculty of Engineering, Universitas Indonesia, Soemantri Brodjonegoro Street, Kampus UI, Depok 16424, Indonesia"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2026,3,9]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"358","DOI":"10.1111\/dmcn.12616","article-title":"Validity and reproducibility of measures of oropharyngeal dysphagia in preschool children with cerebral palsy","volume":"57","author":"Benfer","year":"2015","journal-title":"Dev.
