Sugar process
摘要:
A continuous process for the crystallization of fructose from an aqueous fructose syrup containing at least 90% by weight fructose on a dry solids basis, in which the syrup at a total solids content of at least 95% by weight is rapidly and thoroughly mixed with seed, at a temperature of 55.degree.-75.degree. e.g for up to 2.5 minutes; is then deposited onto a surface where it is allowed to crystallize under quiescent conditions at a temperature of about 50.degree.-70.degree., until a solid cake is formed; and is the comminuted to provide a free-flowing granular product which can be further dried.The process provides a particulate product in the form of crystals in a glossy matrix, in which 95% of the crystals have a particle size of less than 20 microns, the overall degree of crystallinity is greater than 70%, the bulk density is less than 0.65 and which is completely free of organic solvent residues. Other food ingredients may be added simultaneously with the seed.
