Greek yogurt is one of the most popular fermented milk products in the world. The profile of fatty acids is known to influence the nutritional and health prospects of the respective product. The objective of this study was to investigate the fatty acid profile of traditional, strained, and set type Greek yogurt, manufactured from cow, sheep, and goat milk. One hundred and eighteen (118) Greek yogurt samples were collected from the Greek market and analyzed for fatty acid composition by Gas chromatography. One

A total of 25 fatty acids were identified. Palmitic acid was the most abundant fatty acid in all samples, followed by oleic, stearic, and myristic acid. Significant differences for saturated (SFA); C6: 0, C8: 0, C10: 0, C11: 0, C12: 0, C13: 0, C16: 0, C18: 0, and C20: 0, and the unsaturated (UFA); C14: 1, C16: 1, C17: 1, C18: 2n6t, C18: 3n3, CLA, and C20: 3n6 fatty acids were observed between traditional, strained, and set type yogorts. The kind of milk showed a significant effect (\(p<0.001\)) in the profile of all the examined saturated fatty acids as well as most of the unsaturated. Significant differences (\(p<0.001\)) were also observed in fat content for the (SFA) C4: 0, C6: 0, C8: 0, C10: 0, C12: 0, C13:0, C15: 0, C16: 0, and C20: 0 and the (UFA) C14: 1, C16: 1, C17: 1, C18: 1n9t, C18: 3n3, CLA, and C20: 3n6 fatty acids. Additionally, a comparison of specific nutritional indices between yogurt from cow, sheep, and goat milk was attempted. The milk type did not significantly affect the sum of SFA. In contrast, a higher percentage of MUFA and PUFA fatty acids was found in yogurt made from sheep milk. Finally, the n6:n3 ratio of fatty acids was found to be closer to the desired values in sheep and goat milk yogurt rather than in cow milk yogurt.

The extensive and ubiquitous use of emerging contaminants, especially in the aquaculture sector, is a matter of major importance due to the consequences to human health, ecological systems, and food safety [1]. Thus, it is crucial to comprehensively investigate the occurrence of pharmaceuticals and pesticides in fish feeds so as to assess the potential impacts on aquatic ecosystems. In the present study, an accurate and quick quantitation QuECHERS (Quick, Easy, Cheap, Effective, Rugged, and Safe) method for the analysis of the targeted categories of emerging contaminants in fish feed matrices has been developed and validated. It was followed by ultra high-performance liquid chromatography-high-resolution linear ion trap/ Orbitrap mass spectrometry (UHPLC-LC-HR-IT/Orbitrap-MS).
