(57) Abstract:

The invention is intended for use in agriculture, in particular in the ways of cooking food from plant products. The pH value of the juice is adjusted to the isoelectric point of proteins by electrolysis at a voltage magnitude and a constant electric current to the electrodes U = 20 - 60 V; I = 0,5 - 4 A. the Electrolyte when it is placed in the cathode cavity and the juice in the anode and separated from each other by a membrane, ensuring the free movement of ions and preventing the mixing of the working fluids.

The invention relates to agriculture, in particular to the preparation of feed from plant products.

There is a method of deposition of proteins from the juice of plants using organic solvents. As solvents, preference is given to acetone, ethanol, isopropanol. The method comprises adding a solvent, precipitation of the protein, solvent recovery (Novikov ptx2">

However, this method is not used because of the high cost. Even relatively inexpensive solvents (acetone) too expensive, if we are talking about the deposition of protein for feeding purposes. Moreover, the loss of solvent averaged 0.5 kg per one kg protein concentrate (dry matter). Besides, there is energy on the recycling of solvent.

Known deposition method of high-molecular substances from the juice of plants by centrifugation (Novikov Y. F. Obtain protein concentrates of juice of green plants // Agriculture abroad. 1983. N 3. ).

However, this method is not widely used due to the lack of powerful industrial centrifuges with the number of revolutions of the rotor, creating an acceleration of more than 100,000 g. In addition, in this way it is possible deposition only chloroplast fractions of plant proteins, and cytoplasmic fraction, which is more nutritious, remains in solution.

It is known that deposition of protein in a number of countries used the technology of the "Pro-Xan II" and "France-Lucerne". In both technologies for the deposition of protein used heating of the juice to a temperature of 60-65oC. the resulting product Velpro" swich concentrates of juice of green plants // Agriculture abroad. 1983. N 3.).

However, when using thermal coagulation is the denaturation of the protein, thus lost valuable functional properties. In addition, the formation of toxic intermediate agents chlorophyll derivatives. In addition, during thermal deposition method reduces the availability of some essential amino acids that form is not degradable under the action of gastric enzymes connection. The process of thermal coagulation does not provide even short-term storage of coagulate and requires additional application of preservative. In addition, the coagulation process itself consumes a significant amount of energy, which makes up about 60% of all energy required for the entire process.

There is a method of deposition of juice from squeezed biological mass, whereby the pH value is brought by chemical means to the isoelectric point, after which the juice from the pulp is heated to a temperature of 80-85oC (see and. C. Czechoslovakia N 248504, CL A 23 K 1/14, 1987 - prototype).

However, this method requires the use of several technological operations. In addition, you must have warehouse space for storage of chemical objective to precipitate protein from plant SAP.

Technical solution to the problem is to increase the efficiency of deposition and storage time and macromolecular biologically active components from plant SAP.

This object is achieved in that in a method of producing a feed additive from the juice of plants, including the receiving, heating and bringing the pH to the isoelectric point of proteins by electrolysis, where the voltage and constant electric current to the electrodes is U=20-60; I=0.5 to 4 And, when the electrolyte is placed in the cathode cavity and the juice in the anode and separated by membrane, ensuring the free movement of ions.

The claimed method of coagulation juice differs from the prototype in that it does not require the addition of chemicals from the outside.

These differences allow to draw a conclusion on the conformity of the proposed technical solutions to the criterion "novelty".

According to the patent and scientific literature is not found similar inventive combination of the features that allows us to judge about the level of invention.

The invention is illustrated in the drawing, which shows a device which implements the method of obtaining fodder d is 2">

The pressed juice of the plant is placed in the electrolysis chamber 1 into the cavity where the electrode 2 to the anode, the electrolyte is poured into the cavity, which has the electrode 3 to the cathode, these cavities separated by a membrane 4, which is made from several layers of fabric. This membrane allows free moving ions. The electrodes 1 and 2 is fed a constant electric current of 0.5-4 a at a voltage of 20 to 60 C.

An example of the method.

The juice obtained from alfalfa seed in the period optimal content of high molecular weight biologically active substances with the use of a press screw design. The juice using a system of pipes is served in a compartment or cavity of the camera 1, one of the walls which is a non-selective membrane 4, consisting of several layers of thick fabric. In related neighboring compartment is a solution of the electrolyte is NaCl. On the carbon electrodes 2 and 3, located in adjacent compartments of the chamber, served direct electric current with the following parameters: U = 20-60, I = 0,5-4 A. In the course of the process is the electrolysis of water, which resulted in the juice, the accumulation of hydrogen ions, which provide the acidity of the juice and, as a consequence, the achievement of isoelectric townie components of the juice loses its solubility and precipitate. At the end of the process for the separation into fractions of the processed juice through a tap at the bottom of the tank enters the conical sump. Then through the upper valve, the new portion of the juice is fed into the working compartment of the camera.

The method of obtaining the feed additive of the juice of plants, including extraction of juice from plants, heating and bringing the pH of the juice chemically to the protein isoelectric point, characterized in that the pH of the juice is adjusted to the isoelectric point of proteins by electrolysis, where the voltage and constant electric current to the electrodes is U = 20 - 60 V; I = 0.5 to 4 And, when the electrolyte is placed in the cathode cavity and the juice in the anode cavity and separated by a membrane, ensuring the free movement of ions and preventing the mixing of the working fluids.
