Due to the fact that quality haskap wine is a rare product, no research has been carried out on its properties so far. Electrodialysis itself in the wine industry is an innovative deacidification method. In the food industry, electrodialysis is used for other purposes, e.g. in the dairy industry for demineralization of whey, in the fruit and vegetable industry for deacidification of juices and inhibition of enzymes, in the production of organic acids - for their separation from post-fermentation solutions, and is also a permitted oenological treatment for stabilization of products. grape winemaking (removal of tartar). However, no one has so far used the electrodialysis process to deacidify quality fruit wines, which include haskap wine.
