Abstract: A preparation method of a konjac granule includes the following steps: step 1: dissolving a konjac powder in hot water; step 2: subjecting a mixed solution obtained in step 1 to sterilization; step 3: conducting enzymatic hydrolysis at 50° C. to 70° C. for 2 h to 6 h; step 4: conducting enzymatic inactivation; step 5: conducting homogenization at 10 Mpa to 45 Mpa; step 6: adding a fully-dissolved sodium alginate solution and a flavor-modulating substance to a mixed solution obtained in step 5, and thoroughly mixing; and step 7: calcification and gelation: adding a calcium solution to a mixed solution obtained in step 6 for gelation to obtain the konjac granule. The preparation method improves the compactness of the konjac granule, increases a gel strength, and is conducive to extending a shelf life of a product.
