distinguishing feature - the ability to change the geometric dimensions under the
influence of an electric field.
This complex of properties defines various applications conductive
composite hydrogels: as biosensors [115.118], the carriers of drugs at a
controlled rate of release under the action of the electric field [116.120], artificial
muscles elektrostimuliruemyh [121], groceries.
It is now widely use of nanotechnology in the food industry, agriculture -
pesticide and fertilizer products, the production of food is - nano-dispersed,
nano-encapsulated ingredients for functional food; - Biologically active food
supplements; - Food additives with improved functional properties, ie -
nanokonservanty; - A means of improving the taste characteristics; - Anti
bacterial coating; - Nanofiltration; - Nanosensors. To improve food storage used
- protective sprays; packaging materials; nanosensors.
As currently provided in the manufacture of food products:
- The use of nanomaterials to improve the bioavailability of nutrients;
- Insertion of biologically active molecules in nanodroplets for improving
absorption;
- The use of complex nanocrystals cellulose as a carrier of biologically
active substances;
- The use of nano-encapsulated flavor enhancers and flavor;
- The use of nanotubes as thickeners and gelling agents;
- Introduction of nanocapsules steroids in vegetable foods of animal
origin.
Examples of the use of nanomaterials in food production. It - Mars Inc. US
Patent US5741505, namely nanosized inorganic coating. Inorganic nanosized
coatings applied directly to the food product in order to obtain a barrier against
moisture and oxidation, which allows to increase the warranty period of storage
and (or) helps to improve palatability. Coating materials include silicon dioxide
(E551), magnesium oxide (MgO, E530) and titanium dioxide (E171). Are used
in the packaging of confectionery products, instant cereals, biscuits, crisps.
BASF US Patent US5968251 - obtaining carotenoid preparations in the form of
powders, soluble in cold water, and the use of new carotenoid pigments,
lycopene is a nanoparticle having various dyeing properties and improved
bioavailability. Application - soft drinks, baking mixes and so forth..
Modern large-scale fractionation method of food raw materials, based on
the use of polymer membranes with a pore diameter of about 1 nm or less. It
allows for the separation of mixtures with high selectivity proteins, short
peptides, sugars, mineral salts and water. Selectivity nanofiltration membrane
separation depends on the choice of conditions (pH, ionic strength) and may
