Wastewater from the production of mayonnaise is water from washing equipment and contains fats and oils as a
dominant impurity in an average concentration of 0.8 to 3% (mass.). It was noted that in the process of disposal, acid
and alkaline wastewater undergoes an ultrafiltration process, and the separated fats are fed to the soapstock, formed at
the stage of alkaline refining during processing and production of sunflower oil and containing water, soap, absorbed
neutral fat, excess alkali. Further use of soapstock in soap making with the production of natural products is relevant.It
has been experimentally shown that in the production of mayonnaise, a comprehensive 3-stage washing of technological
equipment and pipelines, consisting of an alkaline, acid washing and disinfecting solution treatment, with the inclusion
of additional treatment with hot steam at a temperature of 110 о
C and an overpressure of 0.7 bar for 15 min allows you to
increase the production cycle between equipment washes, reduce the amount of industrial wastewater, and also reduce their
pollution by fats and oils by 3-4 times.It was noted that the frequency of washing, including the processing of equipment
and pipelines assembled with hot steam, should be implemented 1 time in 5 days, which allows to reduce the amount of
wastewater generated by 33% and to reduce costs for these technological operations. In addition, it has been shown that
the additional processing of equipment with hot steam during its complex washing ensures the microbiological safety of
the finished product over the shelf life.
