Enzyme-Catalyzed Production and Chemical Composition of Diacylglycerols from Corn Oil Deodorizer Distillate [PDF]

, 2005
Diacylglycerols (DAG) were enzymatically synthesized by lipase-catalyzed esterification of glycerol with fatty acids from corn oil deodorizer distillate (CrODD). Effects of reaction parameters such as reaction time, temperature, enzyme type, enzyme load,

Rhizomucor miehei lipase remains highly active at water activity below 0.0001

FEBS Letters, 1992
The lipase from Rhizomucor miehei adsorbed on polymer beads retains substantial catalytic activity even after exhaustive drying, and the use of dry box procedures to prevent entry of atmospheric water. Rates of esterification and transesterification (alcoholysis) were measured while stirred in hexane pre‐dried to similar low water activity (a w).

Structure–Property Correlation of Diacylglycerol‐Modified Lipid Bases: Crystallization and Dispersion Behaviors

Food Science &Nutrition, Volume 14, Issue 4, April 2026.
Medium‐chain diacylglycerols were incorporated into fully hydrogenated palm kernel oil stearin (FHPKS) to regulate crystallization behavior and melt–dispersion performance. Low DAG levels (5%–10%) promoted β′‐rich crystal networks and improved thermal responsiveness, establishing a structure–property framework for designing functional lipid bases ...

Development of a Sustainable Biocatalytic Process for Geranyl Benzoate Production Using Immobilized Lipase

ChemistryOpen, Volume 15, Issue 4, April 2026.
This study optimized solvent‐free geranyl benzoate production using Lipozyme 435, achieving 72% conversion in 6 hours. Open reactors improved yields (>99% in 48 hours) by removing inhibitorymethanol. Methyl benzoate reduced enzyme activity by 54%, though Lipura Flex showed better resistance. Human cell tests confirmed no cytotoxicity.

Safety evaluation of the food enzyme acid prolyl endopeptidase from the genetically modified Aspergillus niger strain GEP

EFSA Journal, Volume 24, Issue 2, February 2026.
Abstract The food enzyme acid prolyl endopeptidase is produced with the genetically modified Aspergillus niger strain GEP by DSM Food Specialties B.V. The genetic modifications did not give rise to safety concerns. The food enzyme was considered free from viable cells of the production organism and its DNA.
