Abstract
A glucose in solid form containing a matrix phase and a plurality of carbohydrate crystals within said matrix phase, the matrix phase containing amorphous glucose and water, wherein the carbohydrate crystals comprise glucose and optionally one or more other carbohydrate(s), and optionally wherein the glucose in solid form is coated with a dry powder coating. The glucose in solid form may comprise at least 50 wt % dry substance (DS) glucose and may comprise one or more other carbohydrate(s) besides glucose. A method for manufacturing solidified glucose is also provided.
Claims16
A glucose in solid form comprising:
- a matrix phase comprising amorphous glucose and at least 2 wt % water by weight of the matrix phase, and having a glass transition temperature (Tg) higher than 25° C.;
- and
- a disperse phase comprising a plurality of carbohydrate crystals within said matrix phase,
- wherein the carbohydrate crystals comprise glucose and optionally one or more other carbohydrate(s), wherein the glucose in solid form comprises at least 50wt % by dry substance (DS) of glucose, and optionally wherein the glucose in solid form is coated with a dry powder coating.
A method of manufacturing solidified glucose comprising:
- (i) providing an aqueous glucose solution having a dry substance (DS) of at least 80 wt % relative to the total mass of the solution;
- (ii) providing a powder containing particles comprising a carbohydrate material;
- (iii) adding the powder to the aqueous glucose solution to obtain an aqueous slurry having a glass transition temperature (Tg) higher than 25° C.;
- (iv) cooling the aqueous slurry to a temperature of at most the Tg of said slurry thereby obtaining a product containing solidified glucose comprising an amorphous phase with amorphous glucose and at least 2 wt % water by weight of the matrix phase, and having a glass transition temperature (Tg) higher than 25° C.;
- and
- (v) optionally milling the product containing the solidified glucose and/or coating the solidified glucose or the milled solidified glucose.
