Cold Plasma Induced Lipid Remodeling in Meat: Identifying an Oxidative Threshold Through Integrated Lipid Oxidation and Lipidomics Analysis

Structure-Dependent Triglyceride Protection of Freeze-Dried Lactiplantibacillus plantarum: Storage Protection Window, Lipid Oxidation, and Stress Adaptation

Lipid-rich matrices can protect probiotics by limiting direct exposure to moisture, oxygen, and gastrointestinal stressors. However, triglycerides are chemically dynamic during storage, and differences in fatty acid structure and oxidation susceptibility may determine whether they exert protective or detrimental effect...

Oxidomics of Human Plasma Reveals Lower Oxidized Lipids After Acute Intake of Polyphenol-Enriched Flaxseed Oil: A Randomized Crossover Exercise Trial

Dietary antioxidants offer protection against oxidative bursts caused by high-intensity physical exercise. However, their acute effects on specific lipid oxidation products, especially oxidized phosphatidylcholine (oxPC) and oxysterols, remain underexplored in human plasma. Nineteen female participants underwent a cros...

Cold exposure-induced alterations in n-3 fatty acid profiles and their associations with brown adipose tissue activity.

Brown adipose tissue (BAT) contributes to energy expenditure through cold-induced thermogenesis and is closely linked to systemic lipid metabolism. However, the dynamic changes in circulating n-3 polyunsaturated fatty acids (PUFAs) during cold exposure and their association with BAT activity remain unclear. Healthy you...

Measurement of Lipid Oxidation in Foods and Selected Biological Systems Using LC-MS/MS-Based Lipidomics

Lipid oxidation is an important factor affecting food quality and oxidative stability, but conventional oxidation indices provide limited information on individual oxidation products and changes in lipid species. This review focuses on liquid chromatography-tandem mass spectrometry (LC-MS/MS)-based approaches for lipid...

Effects of Nutraceuticals and Functional Foods on Lipid Profile and Atherogenic Indices in Isoniazid-exposed Rats

Oxidative stress can alter lipid metabolism and promote changes in circulating lipoproteins that may increase atherogenic risk. Isoniazid, although an essential first-line antituberculosis agent, has been associated experimentally with oxidative stress and disturbances in lipid homeostasis. This study evaluated the eff...

Lipid and protein oxidation of foods and their implications on food quality, health, and diseases.
