The present invention discloses a
saury Maillard
peptide with antihyperuricemic activity and its preparation method and application, with the method comprising the following steps:
mincing a
saury, adding water, heating, agitating, adjusting a pH value to 4.2, separating by
centrifugation, and collecting the precipitate; adding water,
proteases and amino acids to the precipitate, adjusting a pH value to 7.0, hydrolyzing, adding a
reducing sugar to cause a reaction, centrifuging and collecting a supernatant which is
saury Maillard
peptide; and
spray drying the
peptide liquid to obtain a
dry powder. The method of the present invention realizes the continuous action of enzymolysis and
Maillard reaction to prepare the Maillard peptide, not only simplifying the production process, shortening the
production cycle, and reducing the production costs, but also significantly enhancing the antihyperuricemic activity of the produced Maillard peptide. Animal experiments in rats showed that the obtained Maillard peptide prepared by the method of the present invention could significantly decrease the level of
serum uric acid in rats, and display certain protective effect in their
kidney.
