Structural and morphological changes induced by DHT and esterification were analyzed using scanning electron microscopy, X\u2010ray diffractometry, and Fourier\u2010Transform Infrared spectroscopy. Starch citrates were characterized for their resistance to pancreatic \u03b1\u2010amylase and amyloglucosidase, as well as their water absorption capacity (WAC) at 37\u00b0C. Results demonstrated a strong correlation between DHT temperature and the functional properties of the final citrate. Increasing the DHT temperature significantly increased the resistant starch fraction and WAC. Specifically, citrates from native starch had a resistant starch (RS) fraction of 91%, while citrates from starch pre\u2010treated at 200\u00b0C exhibited a markedly increased RS fraction of 98% and a 64% increase in WAC. These findings indicate that DHT is an effective pre\u2010treatment for enhancing the dietary fiber potential and hydration properties of starch citrates.<\/jats:p>","DOI":"10.1002\/bip.70125","type":"journal-article","created":{"date-parts":[[2026,9,10]],"date-time":"2026-09-10T06:46:11Z","timestamp":1789022771000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Pre\u2010Esterification Dry Heat Treatment Enhances the Functional Properties of Starch Citrate: Enzyme Resistance and Water Absorption"],"prefix":"10.1002","volume":"117","author":[{"ORCID":"https:\/\/orcid.org\/0009-0009-0607-8734","authenticated-orcid":false,"given":"Anna","family":"Dogadina","sequence":"first","affiliation":[{"name":"Institute of Solid State Chemistry and Mechanochemistry SB RAS  Novosibirsk Russia"},{"name":"Department of Natural Sciences Novosibirsk State University  Novosibirsk Russia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0007-2141-8683","authenticated-orcid":false,"given":"Denis","family":"Tryakhov","sequence":"additional","affiliation":[{"name":"Institute of Solid State Chemistry and Mechanochemistry SB RAS  Novosibirsk Russia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Svetlana","family":"Grishkova","sequence":"additional","affiliation":[{"name":"Institute of Solid State Chemistry and Mechanochemistry SB RAS  Novosibirsk Russia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5433-6966","authenticated-orcid":false,"given":"Daniel","family":"Maslennikov","sequence":"additional","affiliation":[{"name":"Institute of Solid State Chemistry and Mechanochemistry SB RAS  Novosibirsk Russia"},{"name":"Department of Natural Sciences Novosibirsk State University  Novosibirsk Russia"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2026,9,9]]},"reference":[{"key":"e_1_2_9_2_1","doi-asserted-by":"publisher","DOI":"10.1007\/978-3-662-03680-8_1"},{"key":"e_1_2_9_3_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.tifs.2023.104321"},{"key":"e_1_2_9_4_1","doi-asserted-by":"publisher","DOI":"10.1080\/10942912.2024.2318427"},{"key":"e_1_2_9_5_1","doi-asserted-by":"publisher","DOI":"10.3390\/macromol5030040"},{"key":"e_1_2_9_6_1","doi-asserted-by":"publisher","DOI":"10.1177\/8756087909336493"},{"key":"e_1_2_9_7_1","doi-asserted-by":"publisher","DOI":"10.3390\/foods9091311"},{"key":"e_1_2_9_8_1","doi-asserted-by":"publisher","DOI":"10.1002\/star.202200025"},{"key":"e_1_2_9_9_1","unstructured":"C.
