Description
Summary:The current trend in the development of the human community is reduced to solving two main tasks: providing the population with full-fledged food and preserving the environment. Their solution is possible only on the basis of organizing the rational use of natural raw materials, which is hindered by insufficient study of such modern food production processes as ultrafiltration separation of liquid polydisperse systems. The aim of the study was to experimentally determine the optimal values of the driving pressure (DP) and the speed of circulation (V) of curd whey during its ultrafiltration through polymer membranes. The article presents the following research findings: the dependences of the permeability and selectivity of the UPM-20, UPM-50, Biomax 100 and Biomax 300 membranes during ultrafiltration of curd whey on the driving pressure and flow rate in the channel of the baromembrane apparatus are identified; the optimal values for DP=0.28÷0.36 MPa and V=0.25÷0.35 m/s of cassette-type devices for ultrafiltration of modified natural polysaccharides in curd whey are determined; the residual amount of total protein in permeate of curd whey is identified: with the use of UPM-20, UPM-50 membranes it amounts to 0.012-0.013 %, with the use of Biomax 100 and Biomax 300 it amounts to 0.035-0.088 %; the feasibility of the use of Pellicon 2 Biomax memebranes with a threshold delay of 100 kDa and 300 kDa to obtain a highly purified permeate of curd whey is justified.
