Abstract
Flaxseed has been recognized as a superfood worldwide due to its abundance of diverse functional phytochemicals and nutrients. Various studies have shown that flaxseed consumption is beneficial to human health, though methods of processing flaxseed may significantly affect the absorption and metabolism of its bioactive components. Hence, flaxseed was subjected to various processing methods including microwaving treatment, microwave-coupled dry milling, microwave-coupled wet milling, and high-pressure homogenization. In vitro digestion experiments were conducted to assess the impact of these processing techniques on the potential gastrointestinal fate of flaxseed oil. Even though more lipids were released by the flaxseed at the beginning of digestion after it was microwaved and dry-milled, the full digestion of flaxseed oil was still restricted in the intestine. In contrast, oil droplets were more evenly distributed in wet-milled flaxseed milk, and there was a greater release of fatty acids during simulated digestion (7.33 ± 0.21 μmol/mL). Interestingly, wet-milled flaxseed milk showed higher oxidative stability compared with flaxseed powder during digestion despite the larger specific surface area of its oil droplets. This study might provide insight into the choice of flaxseed processing technology for better nutrient delivery efficiency.

LC-MS-based lipidomics analyses of alterations in lipid profiles of Asian sea bass (Lates calcarifer) induced by plasma-activated water treatment. Food Res Int 2024; 177:113866. [PMID: 38225136 DOI: 10.1016/j.foodres.2023.113866] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/19/2023] [Revised: 12/07/2023] [Accepted: 12/14/2023] [Indexed: 01/17/2024]
Abstract
A lipidomics approach based on liquid chromatography-mass spectrometry was employed to investigate alterations in lipid profiles within the muscles of Asian sea bass (ASB) (Lates calcarifer) post-treatment with plasms-activated water (PAW). Lipidomics studies detected 1500 diverse lipid types in ASB muscles; the phosphatidylcholine (PC) lipid subclass constituted the highest number of lipids (21.07 %), followed by triglycerides (TGs, 20.53 %) and phosphatidylethanolamine (PE, 12.73 %). Comparative analysis between PAW-treated ASB and raw ASB revealed the presence of differentially abundant lipids, with 48 lipids accumulating at high levels and 92 at low levels. Pathway enrichment analysis identified a total of seven lipid-related metabolic pathways; glycerophospholipid metabolism emerged as the predominant pathway. Furthermore, the content of saturated fatty acids in PAW-treated ASB increased from 1059.81 μg/g (raw ASB) to 1099.77 μg/g. Conversely, the content of monounsaturated and polyunsaturated fatty acids decreased from 645.81 μg/g and 875.02 μg/g to 640.80 μg/g and 825.25 μg/g, respectively. Collectively, these results indicate significant alterations in ASB lipid profiles following PAW treatment, establishing a theoretical foundation for understanding the mechanism involved in promoting lipid oxidation.
