Glycerolysis of sardine oil catalyzed by a water dependent lipase in different tert-alcohols as reaction medium [PDF]

Grasas y Aceites, 2015
The production of monoacylglycerol rich in polyunsaturated fatty acids (PUFA) via enzymatic glycerolysis of sardine oil in a homogeneous system was evaluated. Reactions were conducted in two different tert-alcohols.

A first attempt into the production of acylglycerol mixtures from Echium oil [PDF]

Frontiers in Bioengineering and Biotechnology, 2016
Enzymatic glycerolysis of Echium oil (Echium plantagineum) has been carried out in the presence of four commercial lipases. Different pretreatment of the reaction mixture, such as high pressure homogenization and addition of food grade monoolein as an ...

The Effect of Different Polyol Precursors on Disordered Spinel ZnAl2O4 Structure Prepared by the Polymeric Citrate Complex Method and the Corresponding Catalytic Behavior in the Glycerolysis of Urea

Small Structures
ZnAl2O4 is a cubic close‐packed oxide with tetrahedral and octahedral sites in the lattice structure. The catalytic activity of ZnAl2O4 is strongly connected with the surface properties caused by the partially inverse spinel ZnAl2O4 structure.

A Comparison of Monoglyceride Production from Microalgaelipids and Rapeseed Oil Catalyzed by Metal Oxides. [PDF]

ChemSusChem
Microalgae is an underutilised source of food with high nutritional value, such as omega 3, −6, and −9. Glycerolysis of microalgal oil is a simple route to obtain emulsifiers rich in these essential fatty acids and this study reports the first use of heterogeneous catalysts for this application.

From liquid to solid: Exploring techniques, applications, and challenges of structured oils as fat replacements in food formulations. [PDF]

Compr Rev Food Sci Food Saf
Abstract Oil structuring is a strategy used to change the physical state of liquid oils to mimic the behavior of solid fats. In the past years, following the legislative bans on using partially hydrogenated fats and recommendations on limiting saturated fatty acid intake, oil structuring has become a fast‐developing research area.

Enzymatic glycerolysis of soybean oil

Journal of the American Oil Chemists' Society, 1998
AbstractEnzymatic glycerolysis of soybean oil was studied. Of the nine lipases that were tested in the initial screening, Pseudomonas sp. resulted in the highest yield of monoglycerides. Lipase from Pseudomonas sp. was further studied for the influence of temperature, thermal stability, enzyme/oil ratio, and glycerol/oil ratio.

Purification of Residual Glycerol from Biodiesel Production as a Value-Added Raw Material for Glycerolysis of Free Fatty Acids in Waste Cooking Oil

Energies, 2022
The crude glycerol produced as a byproduct of transesterification synthesis has very few applications because it comprises of significant amounts of methanol, catalyst, and soap.

Lipase‐mediated plant oil hydrolysis—Toward a quantitative glycerol recovery for the synthesis of pure allyl alcohol and acrylonitrile

European Journal of Lipid Science and Technology, Volume 125, Issue 9, September 2023., 2023
Selection of a suitable lipase provides for quantitative hydrolysis of triacylglycerides without unwanted coproducts. Optimization of the reaction in solely water as sole reaction medium allows for cost efficient conversion of plant oils and and recovery of a highly pure glycerol product as precursor for acrylonitrile synthesis as well as free fatty ...

Modeling the rheological properties of plant‐based foods: Soft matter physics principles

Sustainable Food Proteins, Volume 1, Issue 3, Page 101-132, September 2023., 2023
Next‐generation plant‐based foods are colloidal systems consisting of polymers and particles whose properties can be understood using soft matter physics. Abstract There is growing interest in the design and fabrication of next‐generation plant‐based (NG‐PB) foods that have physicochemical and functional properties that simulate those of traditional ...
