摘要:The Reaction Of 2,5-Dimethyl-4-Hydroxy-3(2H)-Furanone (Dhf) With Aliphatic Alcohols Using A Small Amount Of Strong Acid Catalyst Proceeded,In An Analogous Way To Classical Carboxylic Acid Ester Formation,To Give Good Yields Of The 4-Alkoxy Derivatives. This Raises The Possibility That This Type Of Ester-Like Formation Might occur In Foods That Contain Both Dhf And Alcohols. Odor Threshold Determinations Of 4-Alkoxy Dhf Derivatives From A Number Of Common Food Alcohols Including Methanol,Ethanol,Butanol,3-Methylbutanol,And (Z)-3-Hexenol Showed Them,However,To Be Relatively Weak Odorants.

摘要:The present invention relates to the cloning and expression of cDNA encoding O-methyl transferase for catalyzing the synthesis of vital volatile flavor compounds such as mesifuran and vanillin, thereby playing a significant role in flavor biochemistry of mango. The present invention also provide a process for the preparation of volatile compounds by mesifuran, ferulic acid, guaiacol and vanillin, specifically mesifuran and vanillin using cDNA sequence.
