The invention discloses a preparation method of oxidation-resistant preserved meat essence. The preparation method is characterized by comprising the following steps of taking pork loin,
cutting the taken pork loin into strips, performing thorough cleaning, hanging the cleaned pork strips, and performing airing; uniformly kneading and applying salt to the pork strips, and performing standing for
pickling; hanging the pickled pork strips in a smoking furnace, enabling
cypress branches to be burnt incompletely, and
roasting the pork strips for 2-3 weeks; taking the roasted pork strips, thoroughly washing the taken pork strips with water, and
cutting the washed pork strips into ground meat; adding compound
protein enzymes and water, performing enzymolysis to obtain enzymolysis products, performing
centrifugal filtration on the enzymolysis products, and taking enzymatic
hydrolysate; adding a mixture of glucose and
xylose, amino acids and fat, and performing a reaction under 110-120 DEG C for 50-70min; and separating the reaction liquid to remove lower-layer precipitate, performing freeze-
drying on upper-layer liquid with a vacuum
freeze drying machine, and then performing crushing so as to prepare the oxidation-resistant preserved meat essence. According to the preparation method disclosed by the invention,
natural food materials are used as raw materials, and the used enzymolysis technical conditions are mild, high-efficient and high in safety. The essence is high in
heat stability and vivid in fragrance, has the oxidation-resistant characteristic, and is suitable for addition and use of making preserved meat flavored foods.
