The objective was to observe the effect of the presence of green leaves and dry leaves on technological parameters of sugarcane juice, related to a control treatment with the addition of fiber extracted from the stalks. The experiment was based on the addition of known quantities of fibrous sources, in order to formulate samples with absolute increases of 0.25; 0.50 and 0.75 percentual points over the fiber content of the sugarcane control tretment. The green leaves caused a reduction of the Brix, pol and juice purity, and an increase on the juice content of reducing sugars and ash. These results, statiscally significant at the level of 1% of probability, were expressed by linear regression equations and correlation coeficients. The presence of dry leaves extracted from their stalks as fiber addition, did not induce alterations in the juice.
