The use of liquid sugar in the food industry constitutes a great advantage in applications where the sugar is added in solution. The invert syrup gathers the high solubility of the frutose to the difficult crystallization of the glucose, increasing its sweetness and decreasing the crystallization risks. Those properties contribute to increase the value of those syrups for use in several products, above all in the industry of soft drinks. The objective of this work was improve the stages of invert syrup production using ion exchange resins, seeking to obtain a final product of high quality that assists to the needs of the industry of soft drinks using the experimental design. The production of inverted syrup began with sucrose decolorization process employing two anionic resins columns and subsequent elution through a cationic resin column, which promoted sucrose hydrolysis until inversion level desired. The obtained product was exempted practically of any objection to the palate, scentless, low levels of color (56 ICUMSA) and HMF (11 ppm). Determination of molds, yeasts and bacteria were smaller than 1 unit/mL.
