Title

Application of vacuum-steam-vacuum (VSV) technology for corn decontamination

Pages

  73-87

Abstract

Corn is a nutritious food which is stored in ensilage. Bacterial contamination is the most important problem in a storage condition. Vacuum-Steam-Vacuum (VSV) Technology is a safe technique for Microbial decontamination of food this method the decontaminating was conducted by steam which Statistical Analysis was carried out based on full factorial desi that repeated three times in the form of a plan. Independent variables in this research were temperature (115, 120, 125 ° C), steaming time (15, 20, 25 seconds) and initaial vacuum duration (60, 90 and 120). Dependent variables were total bacterial load, total molds and moisture content, ash, Sensory attributes (color, smell and overall acceptability). The results showed that the best bacterial decontamination was carried out in the following condition: treatment temperature 125 ° C, the first vacuum time 90 s, steaming time 25 s and the second vacuum time of 120 s. In this condition, a decontamination rate of 4 log CFU/g for the total bacterial count and 3. 6 log CFU/g reduction in total mold and yeast was achieved. In treated samples the highest percentage of moisture was estimated at 9. 2% which was lower than national standards (13%). This technology can be adviced as an applicable technique for food decontamination.
