Acompanhamento e análise de tempo de espera para descarga na qualidade tecnológica e microbiológica do arroz

Abstract

The volume of grain has increased significantly and storage structures do not have accompanied this growth may cause loss and damage during processing of grain. According exposed this work was to analyze the effect of waiting time for discharge of paddy rice in the technological and microbiological properties. Samples were acondicionas in three wooden boxes measuring 50x50cm for simulating truck bodies, each box containing on average 75 kg of rice, which were exposed to environments covered with canvas PV C individually. During the seven days were monitored environmental conditions and collected samples for evaluation of moisture performance, faults and enumeration of yeasts and molds. Data were subjected to analysis of variance and Tukey test at 5% probability. The monitoring environmental conditions listening showed that provides conditions for developing microorganism having an internal temperature and humidity in a constant range, had an increased incidence of defects such as damaged kernels and yellow, reducing the typing the rice after the sixth day waiting for discharge . It also showed an increase in yeast and mold counts in the course of seven days to discharge. Not being affected income and no metabolic defects. Can conclude that prolonged waiting for unloading grain rice in the unit Beneficiadora affects technological and microbiological quality.
