Claims (All) Which Will Not Appear on the Advertisement Page: Updated 15/5/2017 1. A method for producing invert syrup products from raw sugarcane juice comprising the steps of (I) passing the juice through a filtration process having at least two filtration stages, a first and a finer stage to remove impurities while the sugar is properly retained in the juice and a pasturization stage to pasturize and concentrate by evaporation the juice by passing the juice to a pasturization temperature between 61.5°C and 72°C for a time sufficient to simultaneously pasturize and concentrate the juice, thus producing the concentrated filtered juice; (ii) passing the concentrated filtered juice through anion exchange to remove soluble impurities from the concentrated filtered juice that were not removed in the filtration process, thus producing the pasturized juice; (iii) exposure to the juice treated by such anion exchange with immobilized invertase enzyme to convert at least 90% of the sucrose contained in such treated juice into a mixture of glucose and fructose and thereby to produce such invert syrup (as amended); 1.
