Special Issue Information

Dear Colleagues,

Diet unquestionably plays a role in the growth, development, and maintenance of body functions. Lipid oxidation is one of the most important chemical reactions occurring in foods, leading to the formation of oxidized products that can be associated with harmful effects on human health, such as hypertension and degenerative diseases of the nervous system, and the construction of undesirable flavors and aromas that can alter the sensory attributes of food and/or reduce their stability and shelf life. This chemical phenomenon directly implicates the commercial and functional value of oils and fats and all products formulated from them. This Special Issue entitled “Advances in Lipid Chemistry: Extraction, Process and Analysis” aims to cover the recent advances in lipid chemistry, including how different downstream processing conditions (e.g., extraction, fractionation) affect the yield, composition, and quality of the extracted oil. This issue aims to emphasize the potential role of novel analytical techniques as a crucial tool to elucidate the complexity of this phenomenon and guide the development of processes that are able to produce lipids with desired composition and quality. Topics include, but are not limited to:

  • Emerging analytical methods to identify early lipid oxidation;
  • The effects of sustainable extraction and fractionation methods on lipid composition and quality;
  • The effects of processing conditions on lipid composition and quality.

Infant milk formulas often contain docosahexaenoic acid (DHA), a highly unsaturated fatty acid that is prone to oxidation. Previously, we reported in oil that the esterified lipid pool is more prone to lipid oxidation than the free pool. However, it is unknown whether added DHA modifies lipid oxidation in infant formula. In the present study, we quantified lipid oxidation rates in infant milk formula containing canola oil (F1) or canola oil supplemented with DHA-ethyl ester (F2). Lipid oxidation kinetics were determined by quantifying esterified and free oxylipins using liquid chromatography-tandem mass spectrometry (LC-MS/MS) during storage for 21 days at 4 °C. Esterified oxylipins increased in concentration within 3 and 7 days of storage in F2 (with DHA) and F1, respectively. Free oxylipins appeared 7 and 14 days later in F2 and F1, respectively. The kinetic estimates revealed that esterified oxylipins formed at a faster rate in both formulas compared to free oxylipins. Surprisingly, in F2 (which contains DHA), the rates of formation of both esterified and free linoleic acid and alpha-linolenic acid-derived oxylipins were higher than in F1. This study demonstrated that in food systems, DHA promotes the oxidation of other PUFAs, and that triacylglycerol/esterified lipids are preferentially oxidized over free fatty acids, highlighting the role of triacylglycerols in lipid oxidation.
