The invention discloses a preserved meat product preservation method. The method comprises the following steps: (1) screening a culture for fermenting a preserved meat product, and establishing preserved meat
fermentation conditions; (2) determining the types and the amount of enzymes and enzymolysis conditions, adding
papain,
pancrelipase, calpains,
pronase and other
enzyme preparations into the
salting process by taking the texture,
flavor, color and the like as indexes, and determining the
enzyme addition amount, the enzymolysis time, the enzymolysis temperature and other enzymolysis method conditions; (3) analyzing the
acid value and change of
peroxide value in the preserved meat production process, and selecting an
antioxidant; and (4) preparing an edible film, establishing a
coating technology, wherein microbes, the
acid value, the
peroxide value and the TBA value are used as indexes, different composite edible film materials such as
chitosan,
modified starch and soy isolate
protein are used, and
nisin or
nisin are added, and performing
antiseptic validity treatment on the product by adopting dipping, spraying and other different
coating technologies. The method is easy to operate and obvious in effect.
