The search for economic and sustainable sources of polyunsaturated fatty acids (PUFAs) within the framework circular economy is encouraged by their proven beneficial effects on health. extraction monkfish liver oil (MLO) synthesis omega-3 ethyl esters was performed to evaluate two blending systems four green solvents in this work. Moreover, potential solubility MLO studied using predictive simu...

BACKGROUND D-isoascorbic acid is a food antioxidant additive and used in accordance with Good Manufacturing Practice (GMP). High solubility in water (about 150 g/L at 25°C) reduces its effectiveness in stabilizing fats and oils. Our research group had successfully synthesized D-isoascorbyl palmitate using immobilized lipase Novozym 435 as a biocatalyst. Low production efficiency of D-isoascorby...

Epigallocatechin gallate (EGCG), the main polyphenolic substance in tea, exhibits well-known biological benefits. In order to improve fat solubility and bioavailability, a novel path for lipase enzymatic transesterification synthesis of acylated EGCG derivatives an ionic liquid solvent was established. The optimal reaction parameters were determined maximum conversion achieved at 98.65%. [Bmim]...

Immobilized Candida antarctica lipase B, Novozym 435, was used as the biocatalyst in the esterification of adipic acid with four different isomers of butanol (n-butanol, sec-butanol, iso-butanol, and tert-butanol). Optimum conditions for the synthesis of adipate esters were obtained using response surface methodology approach with a four-factor-five-level central composite design concerning imp...

Branched-chain esters (BCEs) have found a large number of applications in cosmetics. Among them, neopentyl glycol dilaurate (NPGDL) stands out as an emollient, emulsifier, and skin-conditioning agent. This work presents the synthesis NPGDL solvent-free medium using two most common immobilized lipases: Novozym® 40086 (Rml) 435 (CalB). Results proved that former biocatalyst has lower activity cer...

Abstract The biocatalytic kinetic resolution of cyclic carbonates derived from glycerol is reported. A selection 26 esterases and lipases was tested for the asymmetric hydrolysis model substrate (epichlorohydrin carbonate) in aqueous medium. Among them, Pig Liver Esterase Novozym® 435 showed best selectivity with E =38 49, respectively. Both enzymes were employed conversion 12 derivatives under...
