Oxidative stability of palm - and soybean-based medium- and long-chain triacylglycerol (MLCT) oil blends [PDF]

open access: yes, 2009
BACKGROUND: Medium- and long-chain triacylglyerols (MLCT) enzymatically esterified using Lipozyme RM IM lipase has very low oxidative stability as it does not contain any antioxidants. The aim of this work was to study the ability of various antioxidants

Oxidative Quality of Acid Oils and Fatty Acid Distillates Used in Animal Feeding

open access: yesAnimals, 2021
Acid oils (AO) and fatty acid distillates (FAD) are byproducts from chemical and physical refining of edible oils and fats, respectively. Their high energy value makes their upcycling interesting as alternatives to conventional fats in animal feeding ...

Thermal stability of nanostructurally stabilized zirconium oxide

open access: yesNanotechnology, 2007
Nanostructurally stabilized zirconium oxide (NSZ) hard transparent films were produced without chemical stabilizers by the ion beam assisted deposition technique (IBAD). A transmission electron microscopy study of the samples produced below 150 °C revealed that these films are composed of zirconium oxide (ZrO2) nanocrystallites of diameters 7.5 ± 2.3 ...

Homogenization Pressure and Temperature Affect Protein Partitioning and Oxidative Stability of Emulsions [PDF]

open access: yes, 2013
The oxidative stability of 10 % fish oil-in-water emulsions was investigated for emulsions prepared under different homogenization conditions. Homogenization was conducted at two different pressures (5 or 22.5 MPa), and at two different temperatures (22 ...
