| Research Abstract |
To develop a new distribution system for managing safety and high quality of fresh produces, following researches were conducted : (1) inactivation of microbe irradiated by IR and UV ; (2) prediction of quality of fresh fruit and vegetables during distribution ; (3) development of prediction model for microbial growth during distribution ; (4) CFD prediction of the temperature distribution within a refrigerated truck filled with fresh produces during transport. As a result, following findings were obtained : surface temperature of plate medium inoculated with spore suspension affected survival rate of microbe at UV was irradiated onto the surface ; a developed mathematical model successfully predicted change in L-AsA and total sugar content in garland chrysanthemum ; microbial growth curve predicted by modified Gompertz model agreed with experimental value ; it might be possible to make predictions of eggplant fruit temperature loaded onto a refrigerated truck to some extent by means of CFD.
