Structuring Lipids Through Glycerolysis
, 2020 This thesis covers an investigation into the potential use of enzymatic glycerolysis to convert liquid oils into structural fats through the production of partial acylglycerols, without altering the fatty acid composition of the native oil. Glycerolysis reaction conditions were shown to affect production of mono- and diacylglycerols (MAGs and DAGs) in ...
