In this study, a structured comparative modeling framework was developed to critically evaluate quadratic response surface methodology (RSM) and artificial neural networks (ANNs) with respect to predictive accuracy and optimization performance toward maximum response yield. A three\u2010level, three\u2010factor face\u2010centered central composite design (FCCD) was applied to optimize solvent\u2010based UAE for maximizing the total anthocyanin content (TAC) from Thai glutinous pigmented rice bran. The effects of UAE time (\n                    <jats:italic>X<\/jats:italic>\n                    <jats:sub>1<\/jats:sub>\n                    : 25\u201335\u2009min), UAE temperature (\n                    <jats:italic>X<\/jats:italic>\n                    <jats:sub>2<\/jats:sub>\n                    : 30\u201350\u00b0C), and sample\u2010to\u2010solvent ratio (\n                    <jats:italic>X<\/jats:italic>\n                    <jats:sub>3<\/jats:sub>\n                    : 1:15\u20131:25\u2009g\/mL) were systematically investigated as key UAE factors. The experimental UAE data were well fitted to a second\u2010order polynomial model, exhibiting a high coefficient of determination (\n                    <jats:italic>R<\/jats:italic>\n                    <jats:sup>2<\/jats:sup>\n                    = 0.9742). Response surface analysis revealed that the optimal UAE conditions for achieving the maximum TAC of 4.14\u2009mg C3G\/g DW were a UAE time of 35\u2009min, a UAE temperature of 42.73\u00b0C, and a sample\u2010to\u2010solvent ratio of 1:25\u2009g\/mL using 60 % (\n                    <jats:italic>v<\/jats:italic>\n                    \/\n                    <jats:italic>v<\/jats:italic>\n                    ) aqueous methanol containing 0.1 % citric acid. The ANN model identified the optimal UAE conditions for obtaining the maximum TAC of 4.23\u2009mg C3G\/g DW as an UAE time of 35\u2009min, an UAE temperature of 42.31\u00b0C, and a sample\u2010to\u2010solvent ratio of 1:25\u2009g\/mL. Analysis using ANN predicted TAC response showed a higher\n                    <jats:italic>R<\/jats:italic>\n                    <jats:sup>2<\/jats:sup>\n                    value of 0.9797 and average absolute deviation (AAD) values of 2.78 %, compared with 3.61 % for RSM. Moreover, the root mean squared error (RMSE) for ANN was 0.042, which was lower than that of RSM at 0.047, further demonstrating the superior predictive performance of ANN. This work moves beyond conventional optimization by elucidating the structural limitations of quadratic response surface models and highlighting the adaptive learning capacity of ANN for nonlinear extraction dynamics. By establishing a comparative modeling framework, this study advances machine learning\u2013driven optimization strategies and provides a scalable predictive approach for anthocyanin recovery, supporting the development of high\u2010value extracts for applications in functional foods, pharmaceuticals, and cosmetics.\n                  <\/jats:p>","DOI":"10.1155\/cmm4\/5449309","type":"journal-article","created":{"date-parts":[[2026,4,17]],"date-time":"2026-04-17T14:17:04Z","timestamp":1776435424000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Modeling and Optimization of Solvent\u2010Based Ultrasonic\u2010Assisted Extraction of Glutinous Pigmented Rice Bran\u2032s Total Anthocyanin Content Using Response Surface Methodology (RSM) and Artificial Neural Networks (ANNs)"],"prefix":"10.1155","volume":"2026","author":[{"given":"Suganya","family":"Phantu","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Wachirapong","family":"Jirakitpuwapat","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Thidaporn","family":"Seangwattana","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Rachadawan","family":"Darlai","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7581-0185","authenticated-orcid":false,"given":"Panawan","family":"Suttiarporn","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2026,4,17]]},"reference":[{"key":"e_1_2_9_1_2","first-page":"369","article-title":"Total Flavonoids and Anthocyanins Content of Pigmented Rice","volume":"12","author":"Maulani R.
