Abstract:
1. A method for producing an invert syrup product from raw sugarcane juice comprising the steps of: (i) subjecting sugar cane juice to a filtration process having at least two filtration stages, a first stage and a finer stage, to remove contaminants while substantially retaining sugars present in the juice and a pasteurization stage to pasteurize and evaporatively concentrate said sugar juice by subjecting said sugar juice to a pasteurizing temperature between about 61.5° C. and about 72° C. for a time sufficient to pasteurize and simultaneously concentrate said sugar cane juice, thereby producing a concentrated filtered sugar cane juice; (ii) subjecting the concentrated filtered sugar cane juice to anion exchange to remove soluble contaminants from said concentrated filtered sugar cane juice which were not removed in the filtration process, thereby producing an anion exchange-treated sugar cane juice; (iii) contacting said anion exchange-treated sugarcane juice with an immobilized invertase enzyme to convert at least 90% of sucrose contained in said treated juice to a mixture of glucose and fructose and thereby to produce said invert syrup product.
