FIELD: chemistry.
SUBSTANCE: invention relates to methods of carbohydrate feedstock preserving against microorganisms. Contacting the carbohydrate feedstock in a unit operation is executed. The unit operation involves the carbohydrate feedstock storage or transportation with stabilised chlorine dioxide at a pH of at least 2.6 over a period of at least one month before its use in the fermentation process.
EFFECT: carbohydrate concentration of at least 1% by the feedstock weight, the amount of added stabilised chlorine dioxide ranges from 10 to 10000 mg/kg, as ClO2 based on the total feedstock weight, the microbial population of the preserved feedstock does not undergo an increase of more than 1 log10 CFU/ml or 1 log10 CFU/g for at least one month.
