Fermentation type marine product base material as well as preparation method and application thereof

The invention provides a preparation method and application of a fermented marine base material, and belongs to the field of food processing. The preparation method comprises the following steps: performing enzymolysis on the marine pulp by using the composite proteolytic enzyme, adding the composite strain for fermentation, and further preparing the fermentation type marine base material on the basis of the fermentation liquid. A fermentation treatment means is added in the preparation process of the conventional enzymolysis marine base material, so that the problems that the marine juice is heavy in fishy smell and insufficient in taste and delicate flavor can be solved, the marine juice with rich fragrance and weak fishy smell is prepared, the microbial fermentation efficiency can be effectively improved through enzymolysis, the overall process time is shortened, industrial production is facilitated, and the method is suitable for industrial production. Meanwhile, the obtained marine juice also retains the
