Study of glycerolysis of lactic acid

open access: yesIOP Conference Series: Materials Science and Engineering, 2020
Abstract Increasing production of a biodiesel industry, will also increase the by-product of the industry, glycerol. Further processes were investigated to get an added value of the byproduct. Glycerol esters of lactic acid and in particulars glycerol monolactate is one of the more value of derivative material from glycerol, which is ...

Follow‐up of the re‐evaluation of polyglycerol esters of fatty acids (E 475) as a food additive

open access: yesEFSA Journal, Volume 20, Issue 5, May 2022., 2022
Abstract Polyglycerol esters of fatty acids (PEFA, E 475) was re‐evaluated in 2017 by the former EFSA Panel on Food Additives and Nutrient sources added to Food (ANS). As a follow‐up to this assessment, in this opinion, the Panel on Food Additives and Flavouring (FAF) addresses the data gaps identified to support an amendment of the EU specifications ...

Glicerólise de óleo de peixe catalisada por lipase comercial de Rhizomucor miehei em meio com surfactante de grau alimentício

open access: yesQuímica Nova, 2013
Omega-3 enriched partial acylglycerols are beneficial for human health. The aim of this study was to obtain monoacylglycerols (MAG) and diacylglycerols (DAG) by means of glycerolysis of fish oil catalyzed by a lipase from Rhizomucor miehei in the ...

Separation of glycerolysis product using hexane

open access: yesIOP Conference Series: Materials Science and Engineering, 2016
Hexane is non-polar solvent and it can dissolve triglyceride and free fatty acid. The aim of this research is to get the hexane ratio to the glycerolysis product that can produce product that has the best characteristics. The study was conducted in five stages. In the first stage, the physicochemical properties of palm oil were analysed.

Glycerolysis of fats and methyl esters

open access: yesJournal of the American Oil Chemists' Society, 1997
AbstractThe glycerolysis of methyl esters and triglycerides with crude glycerol, a coproduct from the transesterification of triglycerides, was studied. Three procedures were followed for this conversion. The first procedure was a one‐step glycerolysis with methyl esters. The second procedure was a two‐step process.

Glycerolysis of high free fatty acid oil by heterogeneous catalyst for biodiesel production

open access: yesResults in Engineering, 2022
The most widely used commercial biodiesel production technique, alkali-catalysed transesterification, requires only moderate temperatures and pressures to achieve a more than 98% conversion yield. Unfortunately, oil feedstock's high free fatty acid (FFA)

Structuring vegetable oils through enzymatic glycerolysis for water-in-oil emulsions

open access: yesFood Chemistry, 2023
Enzymatic glycerolysis is a biotechnological process for structuring vegetable oils. This study investigates the kinetics of glycerolysis of peanut oil and explores the potential of the resulting structured oil to enhance the physical stability of water-in-oil emulsions.

Liquid–liquid equilibria for systems glycerol + sardine oil + tert-alcohols [PDF]

open access: yes, 2013
Monoacylglycerols (MAGs) can be produced by lipase-catalyzed glycerolysis of oils and fats at atmospheric pressure and low temperature. The use of organic solvents as reaction media helps to create a homogeneous reaction system between the immiscible ...
