This investigation aimed to determine the influence of the level of turbidity in the antimicrobial effect of ultraviolet light on orange nectar (Citrus sinensis L.). The investigation was conducted in a chamber treatment UVC light with walls of mirror and a lamp ultraviolet light of 15 watts. The nectar, subjected to a process of pasteurization (90 °C, 10 minutes), were inoculated with freeze-dried yeast (Saccharomyces cerevisiae), strain MIT L51, until concentrations of 1.0, 0.1 and 0.01% (w/p) and determine the turbidity of the dilutions, reporting turbidity values of 10564, 1304 and 813 NTU respectively. The samples were exposed to three different doses, 0.57, 1.14 and 1.71 J/cm2 taking a sample witness called "0" minutes, for purposes of initial analysis of microorganisms. Subsequent to the implementation of treatment took place in the tally sheets, amid Sabouraud agar. Obtained dat...
