Abstract
ZOSSI, B. Silvia; CARDENAS, Gerónimo J.; SOROL, Natalia and SASTRE, Marcos. Influence of sugar and nonsugar compounds on sugarcane industrial quality in Tucumán (Argentine Republic). Rev. ind. agric. Tucumán [online]. 2010, vol.87, n.1, pp.15-27. ISSN 1851-3018.
The concentration of sugar and nonsugar compounds, especially those which play a part in colour formation and others which affect direct white sugar manufacturing process, was studied in the four commercial cane varieties most widely grown in Tucumán (Argentine Republic): TUCCP 77-42, LCP 85-384, CP 65-357 and RA 87-3. Trials with clean cane were conducted during the 2004-2007 harvests. Analyzed parameters were: juice extraction, Brix %, pol % in juice and cane, sucrose and sugar recovery. Inorganic nonsugar compounds, such as ash, phosphate and silica, as well as organic ones, such as fibre, starch, anthocyanin and phenolic compounds, amino nitrogen, cis and trans-aconitic acids, indicator value and colour, were studied. Results showed that LCP 85-384 variety had the best factory performance to produce direct white sugar because of its high sucrose and low nonsugar component contents. Second position corresponded to RA 87-3 variety, followed by CP 65-357 and TUCCP 77-42.
