Abstract

The proper management of harvest cane sugar is a key condition for obtaining a high quality raw material. This study aimed to evaluate the agro-industrial properties of cane sugar in various forms of harvest and the residence tomes on the field after burning or cutting. The experiment was carried out on the farm belonging to the Holy Spirit Company John Plant, in Paraíba Forest Zone. The treatments consisted of three ways to harvest and eleven (11) cutting times, there were three ways of collection: cane sugar raw (FC-l)l sugar cane burned and cut (FC-2)l and cane sugar burnt and cut only at the time of transmission (CF-3). Cutting times were as follows: (0, 12, 24, 36, 48, 60. 72, 84, 96, 108 and 120 hours). The samples were analyzed at Cana Payment Laboratory for content Sucrose (LPCTS) of the Company Urina São João The characteristic were analyzed result in the following: soluble solids - ' Brix (%), sucrose content - Pol (%), industrial fiber. (%) Purity (%) and Totais- Reducing Sugars (ART kg / t). The best performance was seen in CF-l , with superiority in features, ' Brix (%) and Pol (%), while purity (%) and ATR had less behavior characteristic PB (%). The best time between harvesting and processing of ways of CF-l and CF-2 harvests period is 36 hours.
