Compared with controlled freezing-point storage alone, the combined treatment significantly inhibited oxidation, volatile nitrogen accumulation, texture softening, and microbial growth. On Day 10, the coating group recorded a total viable count of 4.98 log CFU\/g, which was below the national limit (5 log CFU\/g), whereas the control group went beyond this limit by Day 7. This extended the microbiological and physicochemical acceptability period by approximately 3 days under the present experimental conditions. Untargeted metabolomics revealed 2267 metabolites, and the differentially abundant ones mainly comprised amino acids, heterocyclic compounds, aldehydes, ketones, and esters. KEGG enrichment suggested that changes in linoleic acid metabolism, terpenoid related annotations, the actin cytoskeleton, and the phospholipase D signaling pathway were associated with delayed quality deterioration. This work provides a theoretical basis for the composite biopreservation of aquatic products.<\/jats:p>","DOI":"10.3390\/foods15122091","type":"journal-article","created":{"date-parts":[[2026,6,10]],"date-time":"2026-06-10T09:25:17Z","timestamp":1781083517000},"page":"2091","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Metabolic Regulation of Seasoned White Snakehead Fillets by a Lemon Essential Oil\u2013Rutin\u2013Chitosan Coating Under Controlled Freezing-Point Storage"],"prefix":"10.3390","volume":"15","author":[{"given":"Jiaxin","family":"Han","sequence":"first","affiliation":[{"name":"Meat Processing Key Laboratory of Sichuan Province, College of Food and Biological Engineering, Food Security Publicity and Education Base of Sichuan Province, Chengdu University, Chengdu 610106, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xuefei","family":"Luo","sequence":"additional","affiliation":[{"name":"Meat Processing Key Laboratory of Sichuan Province, College of Food and Biological Engineering, Food Security Publicity and Education Base of Sichuan Province, Chengdu University, Chengdu 610106, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lin","family":"Zhou","sequence":"additional","affiliation":[{"name":"Meat Processing Key Laboratory of Sichuan Province, College of Food and Biological Engineering, Food Security Publicity and Education Base of Sichuan Province, Chengdu University, Chengdu 610106, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Qiaolan","family":"Zhu","sequence":"additional","affiliation":[{"name":"Meat Processing Key Laboratory of Sichuan Province, College of Food and Biological Engineering, Food Security Publicity and Education Base of Sichuan Province, Chengdu University, Chengdu 610106, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xinhui","family":"Wang","sequence":"additional","affiliation":[{"name":"Meat Processing Key Laboratory of Sichuan Province, College of Food and Biological Engineering, Food Security Publicity and Education Base of Sichuan Province, Chengdu University, Chengdu 610106, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0002-5621-7519","authenticated-orcid":false,"given":"Jing","family":"Zhang","sequence":"additional","affiliation":[{"name":"Meat Processing Key Laboratory of Sichuan Province, College of Food and Biological Engineering, Food Security Publicity and Education Base of Sichuan Province, Chengdu University, Chengdu 610106, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0001-1926-6496","authenticated-orcid":false,"given":"Bingliang","family":"Liu","sequence":"additional","affiliation":[{"name":"Meat Processing Key Laboratory of Sichuan Province, College of Food and Biological Engineering, Food Security Publicity and Education Base of Sichuan Province, Chengdu University, Chengdu 610106, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Weijun","family":"Chen","sequence":"additional","affiliation":[{"name":"Meat Processing Key Laboratory of Sichuan Province, College of Food and Biological Engineering, Food Security Publicity and Education Base of Sichuan Province, Chengdu University, Chengdu 610106, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2026,6,10]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"741449","DOI":"10.1016\/j.aquaculture.2024.741449","article-title":"Sex-linked DNA marker screening and characterization in albino northern snakehead (Channa argus var.) via third-generation sequencing and pool resequencing","volume":"594","author":"Dai","year":"2025","journal-title":"Aquaculture"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"3303","DOI":"10.1108\/BFJ-09-2024-0944","article-title":"Technological advancements and challenges in food supply chain management: A scientometric analysis","volume":"127","author":"Kohli","year":"2025","journal-title":"Br.
