The invention discloses a preparation method of a nutritious and healthcare
solid beverage containing dragon fruits. The preparation method includes the steps: (1) cleaning and
cutting: cleaning the dragon fruits, draining water and
cutting the dragon fruits to obtain pulp and peel; (2) peel beating: dicing the peel, adding a
softening and color protecting liquid, performing stirring and mixing, performing beating to obtain peel
slurry; (3)
softening and extraction: heating the peel
slurry to perform extraction to obtain a peel extracting solution; (4) pulp beating: getting the pulp, adding anantioxidant, and performing beating to obtain a
slurry; (5) slurry mixing and
grinding: mixing the peel extracting solution with the pulp slurry, and performing superfine crushing to obtain a full-fruit ultrafine slurry; (6) proportioning and
grinding: performing mixing, dissolving and
grinding to obtain a slurry; and (7) homogenizing and
drying: homogenizing formula slurry, and performing dryingto obtain the nutritious and healthcare
solid beverage containing dragon fruits. The nutritious and healthcare
solid beverage containing dragon fruits is low in cost, good in
flavor, long in
shelf life at normal temperature, sufficient in
nutrition and
active component retention and utilization, remarkable in healthcare function, high in
raw material utilization ratio, high in coarse
fiber content, reasonable in various nutritious component proportion, good in
dissolution and rehydration performances and capable of being prepared ina
mechanization way.
