The invention relates to the technical field of compound
sugar, in particular to an
erythritol crystal, which comprises
erythritol and sweet agents accounting for 1 to 2.5 percent of the weight of the
erythritol. A preparation method of the erythritol
crystal comprises the following steps that the erythritol and the sweet agents are mixed and dissolved to obtain liquid solution, the solution is simultaneously evaporated and crystallized, and the erythritol crystals are obtained; the erythritol and the sweet agents are mixed and are dissolved to obtain liquid solution, the liquid solution is subjected to non-
evaporation crystallization, the filtering is carried out after the
crystallization completion, and the erythritol crystals are obtained; the erythritol and the sweet agents are mixed in a
solid from; and the mixed solids are subjected to melting,
crystallization, crushing and
drying to obtain the erythritol crystals. The
sweetness of the erythritol is improved and reaches more than 80 percent of the
sweetness of the
cane sugar, the consistency of ingredients of compound products of the erythritol and the sweet agents is realized, the problem of cocrystallization of the erythritol and the sweet agents easily carbonized at high temperature is solved, the
crystallization rate is improved to the maximum degree, the crystallization efficiency is 5 to 20 percent higher than that of the traditional crystallization technology, and the application field of the product is enlarged.
