Effect of solvents on the fractionation of high oleic–high stearic sunflower oil [PDF]

open access: yesFood Chemistry, 2015
Solvent fractionation of high oleic-high stearic (HOHS) sunflower oil was studied to determine the best solvent to use (hexane or acetone) in terms of the operational parameters and properties of the final stearins. Acetone fractionation on two types of HOHS sunflower oils (N17 and N20) was carried out at temperatures from 5 to 10 °C using micelles ...

Oxidative stability of high-oleic sunflower oil in a porous starch carrier

Food Chemistry, 2015
This study evaluates the oxidation level of high-oleic sunflower oil (HOSO) plated onto porous starch as an alternative to spray drying. Encapsulated oils were subjected to accelerated oxidation by heat and light exposure, and peroxide value (PV) and conjugated dienes (CD) were measured. Bulk oil was the control.

Lipase-catalysed transesterification of high oleic sunflower oil

Enzyme and Microbial Technology, 2002
The study of enzymatic transesterification of high oleic sunflower oil with butanol by immobilised Lipozyme® was realised in n-hexane and in a solvent-free system. A simplified model, based on the Ping Pong Bi Bi with alcohol competitive inhibition mechanism, was proposed to describe transesterification kinetics.

Dry Fractionation and Crystallization Kinetics of High‐Oleic High‐Stearic Sunflower Oil

Journal of the American Oil Chemists' Society, 2011
AbstractFractionation of fats and oils makes it possible to generate products with specific properties from natural fats that contain a variety of triacylglycerol (TAG) species. High‐oleic high‐stearic (HOHS) sunflower oils contain high levels of saturated fatty acids, mainly stearate, on a high‐oleic background.
