| Abstract: | The fresh-cut Hami melon were treated by using 0.5,1.0,1.5 and 2.0 kGy high energy electron beam irradiation,packed with tray of PP material and 0.03 mm PE film,and stored at the condition of 5 ℃ and RH 85%~95%.The effects of high energy electron beam irradiation on microorganism control and quality of fresh-cut Hami melon were studied.The results showed that,irradiation could inhibit microorganism effectively,higher energy could have better effect.Growth of bacterial,mould and yeast load on the surface of untreated fresh-cut Hami melon increased approximately 2.0 log unit at the 13th day,comparing with 1.5 kGy and 2.0 kGy high energy electron beam irradiation.The fresh-cut Hami melon irradiated at a dose of lower than 2.0 kGy could maintain good quality effectively.Stored 13 days,the fresh-cut Hami melon treated with 1.5 kGy high energy electron beam irradiation was still good in sensory quality,and the luminosity value and the firmness could still reach to 63.10 and 5.98 kg/cm2 respectively,both of which were significantly higher than the control(P<0.05).According to results above,the optimal dose of irradiation on fresh-cut Hami melon was 1.5 kGy. |
