The Application and Research of Red Tetrazoline on the Determination of Food Aerobic Plate Count

As an ordinary food sample,a cooked salted egg sample was used to determine the aerobic plate count in this research.Two different kinds of medium were used as the comparison.The result showed that the plate count agar added 1% red tetrazoline sterile solution was the better method which was easily for number observation and which had the accurate and reliable result.This research offered some references for the food microbiology determine work and the estabishment and amendment of related standard.
