Crystallization resisting method for F55 high fructose corn syrup

The invention discloses a crystallization resisting method for F55 high fructose corn syrup, belonging to the field of corn in-depth processing. In a production line of the F55 high fructose corn syrup, a crystal transformation tank is arranged behind a third refining procedure, the F55 crystal transformation subjected to refining of a third ion exchanging system in the third refining process is kept in the crystal transformation tank at 80 DEG C for 20 minutes, and then the F55 crystal transformation enters a third evaporation procedure. The crystallization resisting method has the advantages that the production method is simple, the operation is easy, the influence on F55 crystal transformation process is small, and the method is suitable for industrial production. The investment cost is low, the crystallization time of the produced F55 high fructose corn syrup at a low temperature can reach 70 days, physicochemical indexes of the crystallization resisting F55 high fructose corn syrup are all within the standard range, and the crystallization resisting F55 high fructose corn syrup has no obvious difference with ordinary F55 high fructose corn syrup.
