Monoglicerídeos: produção por via enzimática e algumas aplicações Monoglycerides: production by enzymatic route and applications

Química Nova, 2008
Monoglycerides (MAG) are non-ionic surfactants, widely used in the pharmaceutical, food and cosmetic industries. Although MAGs are manufactured on an industrial scale by chemical glycerolysis of oils and fats, new developments in lipase catalyzed ...

From Structure to Stability: A Comparative Evaluation of Ammonium‐ and Phosphonium‐Based Deep Eutectic Solvent Catalysts in Glycerolysis

ChemCatChem, Volume 18, Issue 11, 15 June 2026.
Hydrogen‐bond acceptor substitution governs the activity–durability trade‐off in deep eutectic solvent catalysis by altering DES microstructure, component mobility, and response to water ingress, rather than intrinsic acidity, leading to faster kinetics but lower stability (ammonium) versus improved recyclability (phosphonium).

Separation of glycerolysis product using hexane

IOP 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.

Sustainable Recovery of Plant Lipase From Pequi Peel (caryocar brasiliense camb.) in Aqueous Two‐Phase Systems: An Optimization Approach

ChemistrySelect, Volume 10, Issue 46, December 8, 2025.
ABSTRACT While plant residues represent promising low‐cost enzyme sources, their efficient recovery remains a challenge for industrial biocatalysis. This study aimed to optimize thepurification of lipases extracted from pequi peel (Caryocar brasiliense Camb.) using aqueous two‐phase systems (ATPS) composed of polyethylene glycol (PEG) 1500 g/mol and ...
