Monitoring chemical interesterification

JAOCS, Journal of the American Oil Chemists' Society, 1999
AbstractChemical interesterification has long been used to modify oils and fats into functional products. Many chemical compounds can be used as the catalysts, such as sodium metal and sodium methoxide. With addition of the catalyst, the oil turns a well documented distinctive reddish brown.

Chemical interesterification of milkfat and milkfat-corn oil blends

Food Research International, 2003
Abstract Blending and chemical interesterification of fats have been used to modify physical and chemical properties of natural fats. The objective of this study was to produce binary mixtures of butterfat and corn oil that serve as a base for a tablespread, keeping the desirable organoleptic qualities of butter, yet with higher contents of ω-6 fatty

Chemical Interesterification of Blends of Palm Stearin, Coconut Oil, and Canola Oil: Physicochemical Properties

open access: yesJournal of Agricultural and Food Chemistry, 2012
trans-Free interesterified fat was produced for possible usage as a margarine. Palm stearin, coconut oil, and canola oil were used as substrates for chemical interesterification. The main aim of the present study was to evaluate the physicochemical properties of blends of palm stearin, coconut oil, and canola oil submitted to chemical ...

Methanol-enhanced chemical interesterification of sunflower oil with methyl acetate

Fuel, 2013
Abstract The aim of this work was to investigate the commercial mixture of methanolic potassium methoxide as catalyst in chemical interesterification of sunflower oil with methyl acetate. The presence of methanol significantly enhanced the reaction process because it increased the reaction rate, improved the safety of the process and facilitated the ...

Effect of Lard Quality on Chemical Interesterification Catalyzed by KOH/Glycerol

JAOCS, Journal of the American Oil Chemists' Society, 2015
AbstractThe effects of water content, acid value, and peroxide value on interesterification catalyzed by potassium glycerolate (in situ KOH/glycerol) were investigated using lard as a model fat. SEM analysis of KOH/glycerol powder showed that numerous 0.5‐ to 5‐μm porous structures were formed and may play an important role in the interesterification ...

Kinetics of chemical interesterification of sunflower oil with methyl acetate for biodiesel and triacetin production

Chemical Engineering Journal, 2011
Abstract In the present investigation, it has been determined the kinetic parameters for the chemical interesterification of sunflower oil with methyl acetate using potassium methoxide as a catalyst. Due to the presence of methanol, the possible side effects of methanolysis were also considered.
