The invention discloses a preparation method of large-grained trehalose. The preparation method comprises the following specific steps: (1), preparing starch milk; (2), liquefying; (3), performing double enzymolysis; (4), filtering to remove protein; (5), decolorizing; (6), desalting; (7), purifying; (8), performing concentration crystallization; and (9), separating and drying to obtain a finishedproduct. The preparation method has the advantages as follows: the prepared product are large and uniform in granules, the granules with the granule size of 40 meshes or above account for 35% or above and the granules with the granule size of 40 meshes or below account for about 65%; the large-grained trehalose is convenient to use; and when the large-grained trehalose is compounded with salts orsugars, the ratio can be accurately grasped, so that the saltiness of a salt compound product is more uniform, the sweetness of a sugar compound product and a maillard reaction are reduced, and thusthe quality of the compound product can be improved. |
