Abstract

Abstract In this paper, the influence of high-energy electron beam irradiation technology on the microecology of strong-flavor Baijiu Daqu (SBD) was studied. The effects of different irradiation doses (0-3.55 kGy) on the microecology and physicochemical properties of SBD were determined. The interaction between bacteria, fungi, and physicochemical factors in SBD was examined. The potential of 0-1.40 kGy irradiation for pests eradication was analyzed. Under the irradiation dose range of 0.27–1.40 kGy, the micro-ecology of SBD could almost return to the level observed in non-irradiated samples within 3 months, ensuring a storage period of up to 120 d without infestation. Liquefying Power, Saccharifying Power, Acidity and Moisture all meet the industry standards of SBD and can be used for liquor making. The total bacterial count in SBD was approximately 1.4 x 104 CFU/g, while the count of fungi and yeast was about 4.4 x 104 CFU/g. This study provides an experimental reference for the application of electron beam irradiation technology in the insecticidal treatment of SBD.
