Qualidade pós-colheita de cana-de-açúcar colhida sob diferentes formas de tempos de amostragem.

Abstract

The experiment was conducted at the farm belonging to the Holy Spirit Saint John Mill Company, located in the Paraíba Forest Zone. The objective of the study was to evaluate methods of sampling and the time when the cane sugar can stay on the field without a loss in quality of raw material for industrial processing. Methods of sampling , referring to cane sugar in natura were analyzed ; the cane sugar that has undergone a process of burning and immediately cut and cane sugar that has passed through the firing process, and cut some hours after burning ( 0 , 12 , 24 , 36 , 48 , 60 , 72 , 84, 96, 108 and 120 hours). The experimental design was a randomized block design in a factorial 3 x 11, the factors being : three ways to harvest, and eleven analysis times with three replicates , totaling 99 parcelas.As samples were analyzed at the Laboratory of Sugarcane Payment by Sucrose content (LPCTS) Company Mill St. John the technological characteristics of cane sugar that were analyzed are: soluble solids, sucrose , industrial fiber , purity and total recoverable sugars . The best behavior was observed in the form of crop with sugar cane harvest in nature, with superiority in technological characteristics: soluble solids , sucrose , purity , total recoverable sugars and lower value industrial fiber. The maximum time remained in the field with little loss in technological characteristics is 36 hours.
