Total bacteria,mold and yeast in winter jujube powder at various temperature( 100,110,120 ℃) for 1~ 5 min treated by short and medium-wave infrared radiation were measured. Water moisture and color were also tested after thetreatment. The Weibull model was used to analyze the bactericidal curves at different conditions. The results showed that with the increase of temperature and time,the antibactericidal effect were improved,while the water moisture was decreased,the color change increased. Mold and yeast ...
