2. THE ESSENTIAL PROBLEMS OF THE NATIONAL FOOD AND
AGRICULTURAL INDUSTRY:
Resource scarcity of meat, milk,
grain; the lack of quality protein in the
diet
The domestic market dependence of
soybean protein import
Low efficiency of the agro-industrial
complex
Lack of national protein clusterPROTEIN

3. COMMERCIAL IDEA AND MAIN SALES MARKET:
Extrac-
tion of
lipids
Creating of high-
protein analogues
of dairy products
with anti-
allergenic
properties
Creating of
multicomponent
products on the lacto-
vegetarian basis with
probiotic properties
Creating
of protein
pastes
Animal feed
production
Manufacture of
sports and
children’s food
Meat and sausage,

8. THE OFFERED TECHNOLOGY ALLOWS
To save energy costs due to using of water extraction and
biotechnological methods in order to reduce the anti-nutritional
properties of raw materials;
To raise the functional properties of the protein;
To provide a high degree of substrate bioconversion because of
developed multienzymatic composition;
To improve the consistence of fermented products;
To improve the nutritional and biological value of the products;
To reduce the time of the fermentation;
To expand the range of dairy products;
To reduce production costs.

12. The methods of protein preparations from vegetative raw material and
fermented products of a complex raw material composition by type of
yoghurt was offered;
Hydrolysis of polysaccharides of the lupin wholegrain flour by
multienzymatic composition on the basis of cellulase and xylanase
allows to produce a protein concentrates with good functional-and-
technological properties and higher crude protein content;
Consumer properties of fermented products were investigated.
Patent pending:
«The method of obtaining fermented products on the
vegetative- and the lacto-vegetative basis»
PLANS:
- To research the ways to retrieve lipid fraction and its industrial
processing;
- To research of lupin protein isolate technology;
- Creating a past-like dairy-vegetable product.
