Enzymatic Synthesis of Sugar Fatty Acid Esters
Enzymatic synthesis of sugar fatty acid esters was performed in an organic solvent using an immobilized Candida antartica lipase and various sugars and oleic acid as substrates. A high solubility of the sugar in the solvent was needed for a high sugar ester yield. Among the sugars and solvents tested in this study, the highest yield (98 %) was obtained when xylitol and 2-methyl 2-butanol were u...
متن کاملEnzymatic Production of Sugar Fatty Acid Esters
Sugar fatty acid esters (SFAE) are well known as bio-surfactants. Their excellent biodegradability as well as the fact that they are tasteless, odorless, nontoxic, non-irritant and non-ionic explains their increasing importance in numerous areas. On the other hand, for a long time, large scale production of SFAE remained mainly in the realms of organic chemistry and chemical processing. Chemica...
متن کاملKinetic Investigation of Enzymatic Synthesis of Sucrose Fatty Acid Esters from Sucrose and Non-edible Rice Bran Fatty Acid
Enzymatic synthesis of sugar fatty acid esters were performed in an organic solvent using Immobilized Rhizomucor miehei (RMIM) lipase with sucrose and non-edible rice bran fatty acid as substrates. The maximum conversion of sucrose esters up to 78% obtained when sucrose and non-edible rice bran fatty acid were reacted in molar ratio of 1:8, using n-butanol as a solvent and 1% molecular sieves w...
متن کاملOptimized enzymatic synthesis of hesperidin fatty acid esters in a two-phase system containing ionic liquid.
Response surface methodology (RSM) based on a five-level, three-variable central composite design (CCD) was employed for modeling and optimizing the conversion yield of the enzymatic acylation of hesperidin with decanoic acid using immobilized Candida antarctica lipase B (CALB) in a two-phase system containing [bmim]BF(4). The three variables studied (molar ratio of hesperidin to decanoic acid,...
متن کاملThe enzymatic synthesis of fatty acid methyl esters by carboxyl group alkylation.
The reaction was studied by incubation of fatty acid with S-adenosyhnethionine-methylJ4C and isolation of the labeled ester. This was characterized by thin layer and gas-liquid chromatography and by isolation of labeled methanol from alkaline hydrolysates of the ester. Of several substrates tested only S-adenosylmethionine was an effective methyl donor (K,,, = 2.5 X 10F5 M) and oleic acid was t...
