Study on the middle experiment technology of pulse pressure processing of pidan

Pulse pressure technique was optimized to the pidan middle experiment technology. Effects of high voltage value,Na OH concentration and total time of curing on pidan comprehensive sensory evaluation were studied by three factors quadratic rotation design. Results showed that the Na OH solution concentration had the most important influence on the sensory score of pidan,curing time was the second,and high voltage value was the last.Optimum process parameters were thigh voltage amplitude of 122.2 k Pa,Na OH solution concentration of7.56%,and the curing time of 86.7 h,under this conditions,the sensory score was 91.High voltage value and Na OH concentration had obvious mutual effect,high voltage value and curing time had obvious mutual effect.Conclusion:The optimized technology could be quality products fast preserved pidan.
