Abstract:

The aim of this study was the valorization of coffee industry residues, namely spent coffee grounds (SCG) as a source of oil, and silverskin (CS) as a source of both oil and biomass, under the concept of the circular economy. Therefore, crude oil from SCG was used to produce low-calorie structured lipids (SL) for food and pharmaceutical industries, and CS to produce biochar by pyrolysis for biotechnological uses. SL were obtained by acidolysis with caprylic or capric acid, or interesterification with ethyl caprylate or ethyl caprate, in solvent-free media, catalyzed by immobilized sn-1,3 regio

Abstract:

Diacylglycerols (DAG) were synthesised by lipase-catalysed esterification of glycerol with fatty acids from palm oil deodoriser distillate (PODD). Effects of reaction parameters such as reaction time, temperature, enzyme type, enzyme load, substrate mole ratio and water content were determined. The effect of molecular sieves as a water adsorbent was also studied. Rhizomucor mieheilipase (Lipozyme RM IM) was found to be most effective among the lipases screened for DAG production. The following conditions yielded 52% (w/w) DAG: 6h reaction time, 65 °C reaction temperature, 10% (w/w) Lipozyme RM

Abstract:

Ionic liquids are low melting point salts that represent an exciting new class of reaction solvents. Many reactions show advantages when carried out in ionic liquids, either with regard to enhanced reaction rates, improved selectivity, or easier reuse of catalysts. To ascertain the influence of ionic liquids on the enzyme activity, three different ionic liquids 1-butyl-3-methylimidazolium chloride ([bmim] [CI]) 1-butyl-3-methylimidazolium hexafluorophosphate ([bmim] [PF6]) and 1-butyl-3-methylimidazolium tetrafluoroborate ([bmim][BF4]) were synthesized and investigated as potential media for t

Abstract:

An alternative route to produce biodiesel is based on esterification of free fatty acids present in byproducts obtained from vegetable oil refining, such as palm oil fatty acid distillate (PFAD). PFAD is a byproduct of the production of edible palm oil, which contains 96 wt.% of free fatty acids. The purpose of this work was to study biodiesel synthesis via esterification of PFAD with methanol and ethanol, catalyzed by commercial immobilized lipases (Novozym 435, Lipozyme RM-IM, and Lipozyme TL-IM), in a solvent-free system. The effects of reaction parameters such as type of lipase, enzyme amo

Abstract:

Two inorganic solids have been evaluated as supports of Lipozyme RM IM, a Rhizomucor miehei lipase immobilized on a macroporous anion exchange resin, in order to improve its application as a biocatalyst in the synthesis of biofuels. The experimental conditions have been optimized to get the selective transesterification of sunflower oil, by using a multi-factorial design based on the response surface methodology (RSM). In this way, the effects of several reaction parameters on the selective ethanolysis of triglycerides to produce Ecodiesel, a biodiesel-like biofuel constitute by one mole of mo

Abstract:

This work investigates the production of free fatty acids (FFAs) from the enzymatic hydrolysis of macauba kernel oil. Experiments evaluate the effect of different enzymes and the addition of salts, surfactants, and solvents to the reaction medium, as well as the effect of process variables. Results showed that FFA yields obtained for use of Lipozyme RM IM were higher than those obtained from Lipozyme TL IM and Lipozyme 435. The addition of salts and surfactants did not promote increased production of FFAs, while addingn-hexane and heptane to the reaction medium led to an increased reaction rat

Abstract:

Estolides are vegetable-oil-based lubricants obtained from oleic acid or any source of hydroxy fatty acids. In this work, the estolides synthesis from oleic acid and methyl ricinoleate (biodiesel from castor oil), using immobilized commercial lipases (Novozym 435, Lipozyme RM-IM, and Lipozyme TL-IM) in a solvent-free medium was investigated. Acid value was used to monitor the reaction progress by determining the consumption of acid present in the medium. Novozym 435 showed the best performance. Water removal improved the conversion. Novozym 435 was more active at atmospheric pressure. Novozym

Abstract:

Unsaturated free fatty acids (UFFAs), which are rich inα-linolenic and omega-3 fatty acids, were obtained by alkali hydrolysis and urea complexation methods from perilla seed oil and used as the acyl donor to produce structured triacylglycerols (STAGs) catalyzed by Lipozyme RM IM. The results indicated that the content ofα-linolenic acid was increased to 73.16 % after urea complexation methods. The highest incorporation rate ofα-linolenic acid was 58.78 %, which were achieved under the optimum conditions: a molar mass ratio of tripalmitin to UFFAs of 1:12, a reaction time of 48 h and a tempera

Abstract:

High-purity diacylglycerol (DAG) oil was enzymatically obtained from palm oil deodoriser distillate (PODD). Free fatty acids from PODD were esterified with glycerol (2.5:1 fatty acid to glycerol molar ratio) in the presence of 10% (w/w of oil) Rhizomucor mieheilipase (Lipozyme RM IM) and 30% (w/w of oil) molecular sieves and incubated for 6h at 65 °C in a 50 mL bioreactor. After esterification, the products were deacidified by alkaline extraction and the DAG oil was further purified by silica column chromatography. After purification, up to 85.2% (w/w) of DAG was obtained. DAG profile, fatty a
