New method of processing of liquid-acid products

Abstract

The article is devoted to the electropulse method of milk processing. In research work for the processing of milk a unit consisting of a cylindrical glass vessel and a working electrode was developed. To initiate a pulse discharge in a liquid medium, the working electrodes are made of high-strength, corrosion-resistant and environmentally safe metal. The working unit is tested under different electrical and geometrical parameters of the electropulse technology. Tests of the electric pulse system were carried out at the capacity of the battery capacitor 0.25 μF, the distance of the working interelectrode gap 5 mm and the number of pulsed discharges varied 100 ÷ 1500. Experimental studies have determined the effects of a pulsed discharge of milk and the microbiological composition of the product. After the electroimpulse treatment, samples of milk were examined in the testing laboratory of the Karaganda branch of JSC «National Center for Expertise and Certification» for the content of toxic elements, radionuclides, pesticides, pathogenic microorganisms, bacteria of the Escherichia coli group, the number of mesophilic aerobic and facultative anaerobic microorganisms. The obtained results show that the data before and after treatment of the product by the electric pulse method for the maintenance of valuable components of the raw material remained unchanged.
