Study on Irradiation Sterilization and Dose of Vannamei Mixted Feed
In order to regulate the technical conditions of irradiation sterilization for P.vannamei mixed feed,the paper study the impact of irradiation and storage on the microbe quantity,physicochemical properties,nutritional value of the feed by using different doses from 0 to 20kGy of 60Co gamma ray irradiating on vannamei feed,which is the native production of Hainan Province.The study shows that irradiation can decrease effectively the total bacteria and coliform of the vannamei mixed feed,with the D10value 1.36kGy and the D value 3.39kGy of the total bacteria and the D10value 1.81kGy and the D value 2.96kGy of the coliform.It can kill the aerobic bacteria and coliform effectively,and improve health and safety with 4kGy dose radiation.Meanwhile,it has no significant effect on moisture,ash,crude protein,crude fat,crude fiber,total phosphorus and other physical chemicals.The shelf life is 9 months at room temperature.This study provides theoretical guidance for the irradiation sterilization of the vannamei mixed feed.
