The invention belongs to the technical field of
processing of food lipids and flavors and fragrances, particularly discloses a method for preparing cinnamon
flavor esters by ultrasonic-assisted
immobilized lipase and a product, and particularly relates to a method for synthesizing
methyl cinnamate,
ethyl cinnamate and benzyl cinnamate by
synergistic catalysis of ultrasonic
waves and
immobilized lipase. The invention relates to a method for preparing cinnamon
flavor lipid products such as
cinnamyl acetate and the like. According to the method, on the basis that the cinnamon
flavor ester is prepared through
catalysis of the self-made hydrophobic modified ordered mesoporous SiO2
immobilized enzyme, the ultrasonic-assisted enzymatic reaction is added, the problems that a traditional stirring reaction is large in shearing force and the
enzyme is prone to inactivation are solved, and the defects that in an existing technology for preparing the cinnamon flavor ester through an
enzyme method, the enzymatic activity is unstable, the
catalytic efficiency is low, and the reaction time is short are overcome. And the method has the advantages of low product yield, difficulty in separation and the like, and has huge industrial application potential.
