Lipase Catalyzed Ester Synthesis for Food Processing Industries
Lipases are one of the most important industrial biocatalyst which catalyzes the hydrolysis of lipids. It can also reverse the reaction at minimum water activity. Because of this pliable nature, it is widely exploited to catalyze the diverse bioconversion reactions, such as hydrolysis, esterification, interesterification, alcoholysis, acidolysis and aminolysis. The property to synthesize the es...
متن کاملStudy of vitamin ester synthesis by lipase-catalyzed transesterification in organic media.
Immobilized lipase from Candida antarctica (Novozym 435) was used in organic media to catalyze esterifications of vitamins (ascorbic acid and retinol) from hydroxy acid. We described the synthesis of retinyl L-lactate by transesterification between retinol and L-methyl lactate with yield reaching 90% and the synthesis of ascorbyl L-lactate by transesterification between ascorbic acid and L-meth...
متن کاملTwo-step synthesis of fatty acid ethyl ester from soybean oil catalyzed by Yarrowia lipolytica lipase
BACKGROUND Enzymatic biodiesel production by transesterification in solvent media has been investigated intensively, but glycerol, as a by-product, could block the immobilized enzyme and excess n-hexane, as a solution aid, would reduce the productivity of the enzyme. Esterification, a solvent-free and no-glycerol-release system for biodiesel production, has been developed, and two-step catalysi...
متن کاملLipase-Catalyzed Synthesis and Characterization of 6-O-(11-Dodecenoic)-Glucose Ester in Ionic Liquids
Novozym-435 Lipase-catalyzed transesterification of glucose with 11-dodecenoic ethyl ester in ionic liquids was investigated. The effect of substrate ratio, lipase content, and temperature on the activity and stability of lipase was also studied. The highest yield of sugar ester was obtained in 1-buty-3-methyl imidazolium tetrafluoroborate [Bmim][BF4] under such conditions as the reaction tempe...
متن کاملCatalyzed Ester Synthesis Using Candida rugosa Lipase Entrapped by Poly(N-isopropylacrylamide-co-itaconic Acid) Hydrogel
This study reports the synthesis of polymeric matrices based on N-isopropylacrylamide and itaconic acid and its application for immobilization of lipase from Candida rugosa. The lipase was immobilized by entrapment method. Free and immobilized lipase activities, pH and temperature optima, and storage stability were investigated. The optimum temperature for free and entrapped lipase was found to...
