摘要:(Z)-3-Hexen-1-Y1 Esters Are Important Green Top-Note Components Of Food Flavors And Fragrances Effects Of Various Process Conditions On (2)-3-Hexen-1-Y1 Caproate Synthesis Employing Germinated Rapeseed Lipase Acetone Powder In Organic Solvent Were Investigated Rapeseed Lipase Catalyzed Ester Formation More Efficiently With Non-Polar Compared To Polar Solvents Despite High Enzyme Stability In Both Types Of Solvents Maximum Ester Yield (90%) Was Obtained When 0 125 M (Z)-3-Hexen-1-Ol And Caproic Acid Were Reacted At 25 Degrees C For 48 H In The Presence Of 50 G/l Enzyme In Heptane Enzyme Showed Little Sensitivity Towards A(W),With Optimum Yield At 045,While Added Water Did Not Affect Esteryield Esterification Reduced By Increasing Molecular Sieves (>0 0125% W/v) The Highest Yields Of Caproic Acid Were Obtained With Isoamyl Alcohol (93%) Followed By Butanol And (Z)-3-Hexen-1-01 (88%) Respectively Reflecting The Enzyme Specificity For Straight And Branched Chain Alcohols Secondary Alcohols Showed Low Reactivity While Tertiary Alcohol Had Either Very Low Reactivity Or Not Esterified At All A Good Relationship Has Been Found Between Ester Synthesis And The Solvent Polarity (Log P Value) While No Correlation For The Effect Of Solvents On Residual Enzyme Activity Was Observed It May Be Concluded That Germinated Rapeseed Lipase Is A Promising Biocatalyst For The Synthesis Of Valuable Green Flavor Note Compound The Enzyme Also Showed A Wide Range Of Temperature Stability (5-50 Degrees C) (C) 2010 Elsevier B V All Rights Reserved
