SOARES, Eduardo A.; VERRUMA-BERNARDI, Marta R.  y  BORGES, Maria T. M. R.. Physico-chemical and sensory characteristics of sugarcane juice. Rev. de Ciências Agrárias [online]. 2018, vol.41, n.4, pp.261-270. ISSN 0871-018X.  https://doi.org/10.19084/RCA17283.

The aim of this work was to evaluate the physic-chemical and sensorial characteristics of sugarcane juice of RB (Republic of Brazil) varieties. In was evaluated the pH, acidity, ºBrix, Pol, purity, color, turbidity and reducing sugars. The sensorial analysis was evaluated by the color, characteristic aroma, sweet taste, robustness and preference. The results of the physic-chemical analyses showed differences between the varieties, regarding pH, acidity, Brix, purity, color, turbidity and reducing sugars. The varieties did not present difference for the attribute polarimetry. It was verified that the color of varieties RB855156, RB867515 and RB965917 was the lightest, for the attribute characteristic aroma, varieties RB855453 and RB935744 showed the highest intensity. For attributes robustness, sweet taste and preference, there was no significant difference among the varieties. The physic-chemical and sensory characteristics did not influence the preference of juices elaborated with different sugarcane varieties. Since all varieties presented good phytosanitary conditions, in this region, it is possible to promote a combined planting among the varieties, in order to obtain a greater genetic diversity, as well as better raw material availability throughout the year.
