INTRODUCTION 
Nowadays growing the fruit of pomegranate in the 
world consists of 3,086 million tons. In particular, it was 
harvested in India 900 thousand tons, Iran 800, China 290, 
Turkey 220, the USA 200, Pakistan 120, Afghanistan 90, 
Tunisia 85, Azerbaijan 82, Syria 79 and Uzbekistan 60 
thousand tons in 2016
(1). That is why most of scientific 
researches are directed to introduce technologies in 
order to accelerated develop processing the pomegranate 
juice, to produce juice, concentrate and other assortments. 
There were created wide range of scientific designs on 
storing fruit-vegetables and implementation of processing 
technologies, producing exporting juices in food industry 
of our republic and they were implemented to the pro-
duction. In the Action strategy on further development of 
the Republic of Uzbekistan were set tasks such as 
“deepening structural changes and deep development of 
producing agrarian products, further strengthening food 
safety of the country, widening producing ecologically 
pure products, to increase export capacity of agrarian 
sector” (2). At this point, scientific researches directed

to creation manufacturing technologies of exporting 
productions is of topical issue. 
In this work, we will look at the experimental stand, 
the method of juice purification and the results of the 
experiment and the others in the study conducted on the 
qualitative purification of pomegranate juice using elec-
troflotation. 
It is known that when dividing non-uniform liquids 
in the industry: suspensions, emulsions are performed 
mainly on the account of tender or centrifugal force. On 
the basis of centrifugal force, a complex device is consid-
ered, centrifuges and, in most cases, the purification 
process are used. 
In the food industry, liquid products are considered 
to be heterogenic system and are structured from two 
phases to a dispersing environment and a dispersing 
phase. If in the liquid system there is a strong contact 
between the dispersing medium and the dispersing 
phase, such liquids are hydrophilic, the bond medium 
consists of water, and its hydrophilic shell is surrounded 
by aqueous products. To these is an example of the sus-
pension of starch. If the interdependence in the phase 
with the environment in a system is weak, they are called 
hydrophobic systems. These are examples of protein 
suspension, oil and water emulsions. 
If in the liquid phase the gas bubbles of the dispers-
ing phase stick out, this process is called the flotation 
process. At present, different methods of flotation have 
been developed (3). One of these is electroflotation in 
which positive results have been obtained in many areas 
of the food industry and in the processing of wine mate-
rials and others. Therefore, we conducted the study on 
the qualitative purification of pomegranate juice by this 
method.
