Description
Technical field
The present invention relates to fructose syrup production field, more particularly to a kind of preparation method of F55 fructose syrups.
Background technology
Fructose is a kind of left-handed hexose, is the isomers of glucose, but it is more easy to be absorbed by organisms utilization than glucose,
It is more suitable for diabetes and the energy supply of hepatopath.Fructose syrup is after being hydrolyzed into glucose by plant amylum, using
Made of the isomerization of immobilized isomerase, main sugar ingredient is the syrup of glucose and fructose.Fructose syrup is broadly divided into
The products such as F42, F55, F90, wherein " F " indicates that fructose, digital representation fructose content thereafter account for the percentage of dry matter.Fruit Portugal
The application of syrup is popularized on food industry, health food already, as fructose syrup in recent years is in medical industry, daily seasoning
Application on product, daily-use chemical industry gradually rises, and fructose syrup gradually replaces white granulated sugar.
But fructose syrup is easily crystallized in low-temperature storage, therefore when temperature is low (such as winter), it can strong influence fruit
The convenience that glucose slurry is stored and used, shortens turn around time, increases enterprise's items operation cost.Such as common F55 type fruits
Glucose is starched, and when it is hypersaturated state when less than 20 DEG C, therefore is stored at 0 DEG C -10 DEG C, is most easily crystallized, is only capable of
It stores nearly one month, i.e., crystalline polamer can occur.Once occurring nucleus in syrup, then crystallization rate, serious shadow are accelerated in rear extended meeting
It rings and uses.
