Abstract

The invention belongs to the technical field of irradiation sterilization, and particularly relates to an irradiation sterilization method of seasoning powder. The irradiation sterilization method ofthe seasoning powder comprises the following steps of S(1), sequentially adding glycyrrhizin, carboxymethyl chitosan and the seasoning powder into purified water which is 2-5 times of the total mass of the weighed materials, mixing, carrying out high-pressure homogenization, and carrying out spray drying to obtain mixed powder; S(2), putting the mixed powder obtained in the step S(1) into a polyethylene packaging bag, vacuumizing, filling nitrogen into the packaging bag, and sealing to obtain pretreated mixed powder; and S(3), putting the pretreated mixed powder obtained in the step S(2) in the center of a tray, then putting the tray on a circulating vehicle, starting an electron beam accelerator to carry out irradiation treatment for 20-50 minutes, and carrying out inspection to obtain the seasoning powder. The irradiation sterilization method is good in sterilization effect, and the obtained seasoning powder has relatively good safety and shelf stability.

Description

technical field [0001] The invention belongs to the technical field of radiation sterilization, and in particular relates to a method for radiation sterilization of seasoning powder. Background technique [0002] Seasoning powders include single seasoning powders such as pepper noodles, chili noodles, Chinese prickly ash noodles, raw powder, flour, monosodium glutamate, and compound seasoning powders that also include multiple components, occupying an important position in food. Seasoning powders are susceptible to contamination by heat-resistant bacterial spores and molds. During food sales and storage, the microorganisms brought in by seasoning powder will grow beyond a certain range, and when they are added to food, it is easy to contaminate food and cause food poisoning. [0003] Food sterilization techniques mainly include physical methods, biochemical methods, ozone methods, and irradiation methods. Among them, the irradiation method refers to the use of γ-rays produ...
