Abstract

In order to reduce the price of dairy products and exclude environmental damage caused by improper utilization of whey, it is necessary to ensure its 100% processing by applying advanced innovative technology. Acid whey processing is the biggest problem in the production of lactose by applying the existing technology. Therefore such whey requires further  processing. First and foremost, it is necessary to provide partial demineralization and reduction of acidity. In modern conditions, the reduction of acidity in dairy enterprises is carried out by adding of an alkaline reagent. The introduction of alkali affects the quality of the product. Electrodialysis using bipolar membranes can be applied as an alternative to alkaline treatment of milk whey. Innovative technology is a combination of classic and bipolar electrodialysis. Acid whey demineralization and acidity correction will be performed without the use of additional reagents. In order to reduce the buffer volume (4 times), partially demineralize whey and reduce its acidity (up to 30%), the milk whey is nanofiltered before electrodialysis.
