(57) Abstract:

The invention relates to technologies for primary processing of crop products, food and fodder before putting it into storage. The method involves coating the surface of the crop production antiseptic in the form of a saturated aqueous preparation obtained from biomass micromycete rtierella polycephala for a given technology. Is simplification of the process of preparation and use of an antiseptic.

The invention relates to technologies for primary processing of crop products, food and fodder before putting it into storage.

A method of processing crop products before putting it into storage, providing for coating the surface of the liquid antiseptic in the form of propionic acid (Roslyakov, Y. F. Theoretical and applied principles of conservation of a grain of rice. Dis. D. the so-called - Krasnodar: Kuban state University of technology, 1997, S. 14-16).

The disadvantages of this method are the changes in the chemical composition of the products as a result of surface acid hydrolysis and selective action on the microflora.

Closest to the proposed by distillatively coating the surface of the liquid antiseptic in the form of an emulsion, containing an effective amount of arachidonic and/or zhasmonovoi, and/or eykozapentaenovuyu acid, or their lower alkalemia esters, antioxidant and urea (EN 2127968 C1, 27.03.1999).

This method eliminates surface hydrolysis of processed products and has a high reliability when the potential for secondary contamination, but is difficult to implement because of the complexity of the preparation of the emulsion and the need to prevent delamination.

The technical result of the invention is to simplify the technology.

This result is achieved in that in the method of processing of crop products before putting it into storage, providing for coating the surface of the liquid antiseptic, according to the invention, as an antiseptic use a saturated aqueous solution of the drug obtained by sequential extraction of biomass micromycete Mortierella polycephala nonpolar solvent in the supercritical state, water, alkali, water, acid, water, alkali and water followed by combining the first extract from the solid residue.

The method is implemented as follows.

Dry biomass micromycete Mortierella polycephala of extras the stage separating the first extract, used in the future when receiving the drug. Further biomass sequentially extracted with water, alkali, water, acid, water, alkali and water. Obtained after completing all these stages of extraction of the solid residue combined with the first extract. Made so the drug is dissolved in a saturated water. The resulting solution was applied to the surface allocated for the storage of plant products by any known method. Use of the solution instead of the emulsion as facilitates the process of preparation of the working fluid, and its storage and use in a homogeneous condition. It is known that these components of the working fluid, such as water and carbon dioxide, and food are not harmful to humans and animals. We first established that the drug obtained from biomass micromycete Mortierella polycephala by the above-described technology, contains no toxic or anti-nutritional substances and can be used in the processing of food or feed raw materials.

The use of saturated water not only ensures the solubility of the drug from biomass micromycete Mortierella polycephala, but also creates anaerobic conditions in the treatment area products that Preparata from biomass micromycete Mortierella polycephala includes arachidonic and eicosapentaenoic acid and chitosan, providing immunization plants, and does not include inhibitors of these phyto-toxic substances or substances that can worsen the conditions of storage of plant products.

Experiments have shown that when implementing the proposed method and the closest analogue losses during storage of wheat and oats, potatoes, carrots, beets, zucchini, tomatoes, cucumbers, apples, pears, grapes, quinces, cherries, sweet cherries and black currants are practically identical.

Thus, the proposed method allows to simplify the technology of processing of crop products before putting it into storage.

The method of processing of crop products before putting it into storage, providing surface application of liquid antiseptics, characterized in that as an antiseptic use a saturated aqueous solution of the drug obtained by sequential extraction of biomass micromycete Mortierella polycephala nonpolar solvent in the supercritical state, water, alkali, water, acid, water, alkali and water followed by combining the first extract from the solid residue.
