Butia Yatay coconut oil: Process development for biodiesel production and kinetics of esterification with ethanol
The aim of this work is to study biodiesel production using Butia Yatay coconut oil. This oil has acid values between 109 and 140 mg KOH/g, and phosphorus content in the order of 600 ppm. A three-step degumming pre-treatment ...
Pectin esterification degree in the bioavailability of non heme iron in women
Pectins are a type of soluble fiber present in natural and processed foods. Evidence regarding the effect of esterification degree of pectins on iron absorption in humans is scarce. In the present study, the effect of ...
Screening of Food Grade Lipases to be Used in Esterification and Interesterification Reactions of Industrial Interest
(HUMANA PRESS INC, 2010)
Seven food grade commercially available lipases were immobilized by covalent binding on polysiloxane-polyvinyl alcohol (POS-PVA) hybrid composite and screened to mediate reactions of industrial interest. The synthesis of ...
Surface esterification of cellulose nanofibers by simple organocatalytic methodology
Bacterial cellulose nanofibers were esterified with two short carboxylic acids by means of a simpleand novel organic acid-catalyzed route. The methodology proposed relayed on the use of a non-toxicbiobased -hydroxycarboxylic ...
Effect of methyl branching of C8H18 alkanes and water activity on lipase-catalyzed enantioselective esterification of ibuprofen
(Pontificia Universidad Católica de Valparaíso, 2008)
Comparative esterification of phenylpropanoids versus hydrophenylpropanoids acids catalyzed by lipase in organic solvent media
(Pontificia Universidad Católica de Valparaíso, 2007)
Screening of lipases with unusual high activity in the sn-2 esterification of 1,3-dicaprin under mild operating conditions
(American Chemical Society, 2017-06-02)
In this work, the synthesis of acylglycerides with high nutritional value was carried out by enzymatic esterification at sn-2 position of 1,3-dicaprin with palmitic acid. A comparative study of the performance of several ...
Synthesis of EDTA core dendrimers through a consecutive esterification-CuAAC process
(Taylor and Francis, 2018)
Heterogeneous esterification of oil with high amount of free fatty acids
Frying oils have become the newest raw material for the transesterification reaction for the production of biodiesel. However, these compounds usually come with a certain amount of free fatty acids. These impurities can ...
