Abstract:Based on the study of GNa solution,nisin and lysozy me combinative fresh-keeping experiments, further orthog onal experiment of GNa solution,nisin and lysozy me were developed for a better fresh-keeping effect.The result of L9(34)orthog onal experiment showed three kinds of preservative used combinative has a sig nificant fresh-keeping effect on nonvaccum tray packag echilled meat.It can have a safe preserve period over 24day sunder 0~4℃ The optimum orthog onal experiment process conditions were A3B2C2D2.The condition of GNa solution, nisin and lysozy me were 5000ppm,2500ppm and 2500ppm,respectively and pH was 4.5 by lactic acid.
