The preparation method comprises the following steps: step 1, weighing edible
starch and
maltodextrin, dissolving the weighed edible
starch and
maltodextrin in cold water, heating and boiling the edible
starch and
maltodextrin until the edible starch and maltodextrin are transparent after the edible starch and maltodextrin are fully dissolved, and cooling the edible starch and maltodextrin to normal temperature; step 2, adding the cheese sauce into the cooled
starch solution, fully and uniformly stirring, and passing through a
colloid mill; step 3, adding the fruit grains or nut grains into the blended cheese sauce, uniformly stirring, and pouring into a mold; 4, putting the molded product into a quick-freezing bin for freezing, wherein the freezing temperature is 30 DEG C below zero to 40 DEG C below zero; then putting into a
vacuum drying bin for
drying, wherein the
drying vacuum degree is 60-140 pa; the highest
drying temperature is 55 DEG C; and step 5, after drying is completed, detecting by using a
metal detector, and packaging into a finished product after manual selection. The flavored cheese blocks processed by the technical scheme provided by the invention can be stored at normal temperature, the
shelf life is 12 months, nutritional ingredients are not lost, the
protein content is high, and meanwhile, nutritional substances such as fruits, nuts and the like are added, so that the cheese is balanced in
nutrition.
