For this purpose the sirup is concentrated by evaporation to have 70% to 77% of dry substance by weight. Then the concentrated sirup is crystallized by cooling, whereupon the crystal mass is separated from the mother liquor and aged. An after-crystallization takes place during the aging. Thereafter, the aged crystal mass is milled to have a particle size of about 10 to about 250 microns. The mother liquor is also concentrated by evaporation to have about 90% of dry substance by weight. Then the milled crystal mass and the concentrated mother liquor are mixed with each other, whereby drying and mixing take place simultaneously. The quantities of the two components being mixed are so adjusted that the resulting mixture or end product has a fructose content of maximally 42% to 45% by weight of the end product. | |
