The invention discloses a method for inducing
aroma enhancement of egg
yolk hydrolysate by utilizing
Maillard reaction, and belongs to the technical field of
food processing. The method disclosed by the invention comprises the following steps: taking fresh egg
yolk, homogenizing, adding water, adjusting the pH value to 7-8, respectively adding
protease and
cysteine endonuclease for reaction, and taking supernatant after the reaction, thereby obtaining the
aroma-enhanced egg
yolk protein hydrolysate. Then
xylose is added, the initial pH is adjusted to 7.0-7.5, and homogenization treatment is performed; and carrying out
spray drying on the homogenized
system to obtain
powder, placing the
powder in a sealed container, and carrying out a
dry heat reaction to obtain the
aroma-enhanced egg yolk
hydrolysate. The egg yolk hydrolysate is rich in characteristic volatile compounds such as furans, pyrazines, aldehydes and the like, presents rich toast bread fragrance, nut fragrance, soft meat fragrance and scorch fragrance, has excellent
oxidation resistance, and improves
flavor and optimizes taste experience through synergism of
amino acid and
nucleotide; the product is used as a natural
flavor base material for
food processing of seasonings, meat products, egg products and the like, the process is simple and controllable, and the method is suitable for industrial production.
