Comparison of three methods for rendering plant fat transesterification

Research in Agricultural Engineering, 2013
Three most frequently used methods for fat transesterification were compared using rendering plant fat (RPF) as model. Acid-catalysed transesterification was found to be the most effective (conversion 90%) at optimum conditions (fat: methanol ratio 1:10,

Stabilization of PUFA‐Rich Mayonnaise Against Lipid Oxidation: A Review of the Last Three Decades of Research

Journal of the American Oil Chemists' Society, EarlyView.
ABSTRACT Mayonnaise, a widely consumed oil‐in‐water emulsion, is highly susceptible to lipid oxidation due to its high content of polyunsaturated fatty acids (PUFAs) and the presence of pro‐oxidant factors such as low pH and iron from egg yolk. Over the past three decades, extensive research has focused on understanding oxidation mechanisms, analytical

Comparative effects of biomass pre-treatments for direct and indirect transesterification to enhance microalgal lipid recovery

Frontiers in Energy Research, 2014
Microalgal lipid recovery for biodiesel production is currently considered suboptimal, but pre-treatment of algal biomass, the use of solvent mixtures and the positioning of transesterification can lead to increased yields.

Revisiting Securidaca longipedunculata Seed Oil: Applying NMR and Mass Spectroscopy to Confirm the Presence of 2‐Acetyl‐1,3‐Diacyl–sn‐Glycerols and Conjugated Hydroxydienoic Fatty Acids

Journal of the American Oil Chemists' Society, EarlyView.
The manuscript confirms and expands on previous reports concerning the presence of unusual conjugated hydroxydienoic fatty acids and acetyl‐TAG in the seed oil of Securidaca longipedunculata. The location of acetate only at sn‐2 of TAG was conclusively shown by high resolution NMR and hydroxy seed fatty acids are characterized.
