Sampling within fillets was conducted at six positions along the anteroposterior, dorsoventral, and radial axes. Lipid analysis was performed using gas chromatography. The results show that feed had the biggest influence on fatty acid profiles, followed by sampling position, while growth stage had minimal influence. Substantial differences in fatty acid compositions were observed along both the dorsoventral and anteroposterior axes of the fillets. The Norwegian Quality Cut (NQC) area closely reflects the median fillet composition, making it a reliable reference region. Fillet areas with low lipid content, particularly the tail section, have the highest DHA and EPA content.

Advances in modern analytical techniques have enabled researchers to investigate the spatial distribution patterns of bioactive food components and their interaction mechanisms with biological systems more comprehensively. Mass spectrometry imaging (MSI), an emerging spatial histology tool, offers a novel perspective for studying the mechanisms of bioactive food factors. By leveraging <em>in situ</em>, label-free molecular imaging capabilities, MSI visualizes the spatial distribution of functional compounds within food matrices, providing critical technical support for analyzing their biological activities and metabolic pathways. This paper systematically reviews recent advancements in MSI principles and workflows for bioactive food component research, while addressing current technological challenges, such as high hardware costs, signal interference from complex matrices, and limited sensitivity for trace-level analytes. Future integration of high-resolution mass spectrometry with artificial intelligence algorithms is expected to enhance the potential of MSI in tracking <em>in vivo</em> nutrient metabolism and designing targeted nutrient delivery systems.</div></div>","PeriodicalId":15867,"journal":{"name":"Journal of Food Composition and Analysis","volume":"148 ","pages":"Article 108355"},"PeriodicalIF":4.6,"publicationDate":"2025-09-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145154777","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, improper use of MBF may leave residues in edible animal tissues and milk, posing a potential hazard to human health.
