| Abstract: | In this experiment,the effect of temperature on conductivity of juice and the quality changes during storage of different treated watermelon were studied.The results show that the conductivity of freeze concentrated juice could be handled by controlling temperature to reach the sterilization.After freeze concentrated watermelon juice treated by PEF,it met the national standard.During the storage,the pH value,solid concentration did not change and the concentration of Vc was going down.With the sensory evaluation of juice treated by different ways,the result showed that the juice treated by freeze concentration and PEF was more closed to fresh juice. |
