Description

The invention relates to agriculture, namely, to obtain a vitamin feed additive from wheat grains for feeding farm animals and birds.

A known method of producing a feed vitamin supplement, characterized by grinding the feedstock, adding water, heat treating the obtained substrate, fermenting growing yeast under conditions of aeration on a nutrient medium, followed by isolation of the target product, obtain a suspension with a solids concentration of at least 6% and for more than 24 h from the time of preparation canned hypochlorite in the form of 5% aqueous solutions in a dosage of 0.005-0.01% by volume of suspension (active chlorine) (US Pat. RU No. 2290831).

The disadvantages of the method of obtaining feed vitamin supplements are significant energy costs, as well as an additional intake - the cultivation of yeast cultures, as well as the use of preservative agents, which, in turn, can have an adverse effect on the body of farm animals.

There is also known a method of growing green hydroponic feed (US Pat. RU No. 2429592), including pre-soaking the seed with activated water with a pH of 8-10, obtained by electrolysis, in a rarefied medium at a pressure of 650-680 mm Hg with simultaneous stirring for 5-9 minutes with a drum speed of 10 rpm

The disadvantage of this method is the use for soaking seed of a vacuum medium created by a special device.

The closest prototype analogue to the claimed one is a known method for producing hydroponic green food, including soaking seeds in catholyte with electroactivated water, which is obtained by electroactivation of a 4-6% solution of ammonium sulfate with a pH of 9-10, redox potential (-800) - ( -900) mV, with a specific consumption of electricity of 0.062-0.070 A / h per 1 liter of catholyte and anolyte, soaked for 3-5 hours with a total germination time of 10 days: the first 2 days without lighting, the next 8 days under lighting, and you onku seedlings (Pat RU №2524538 -. prototype).

The disadvantage of this method is the significant complexity of the process of germination of grain and its complication due to the use of two phases of germination - without light and in its presence, as well as the formation of ammonia on the cathode during electrolysis, which can have an adverse effect on the body of farm animals and birds. This method does not allow to reduce the duration of germination without loss of quality of green feed.

Known methods do not allow to obtain high-quality vitamin feed supplement in a short time without additional labor costs and loss of quality of raw materials.

The technical result is to increase the energy of germination of wheat grains, increase the yield of biomass and plant productivity (feed), to protect seedlings from diseases and to accelerate the process of germinating vitamin greens from wheat grains.

The technical result is achieved in that in a method for producing a vitamin feed additive from wheat, comprising soaking the grain in electroactivated water, germinating and pasturing seedlings, according to the invention, the washing of wheat grain is carried out with tap water for 4-8 minutes, after which the washed grain is soaked with anolyte with pH 3.0-6.0 and a redox potential of 970-1110 mV, an oxygen concentration of 8.3-12.0 mg / l and chlorine 0.006-0.01 mg / l for 3.5-4.5 hours at the ratio of grain to anolyte 1: 2, then remove the anolyte and re-washing the grain with tap water for 3-8 minutes, and the germination of the grain is carried out in a thin layer without using the substrate by the air-irrigation method with periodic tedding, with a total germination time of 7-9 days in natural light.

The novelty of the proposed method for producing vitamin feed additives is to increase the energy of germination of wheat grains and increase the yield of biomass and plant productivity (feed) by protecting the seedlings from disease as a result of the use of anolyte with a pH of 3.0-6.0 units. and a redox potential of 970-1110 mV, an oxygen concentration of 8.3-12.0 mg / l and chlorine of 0.006-0.01 mg / l, as well as a reduction in the duration of germination without loss of quality of the feed additive with minimal material and labor costs.

The features that distinguish the claimed technical solution from the prototype are aimed at achieving a technical result and were not identified when studying patent and scientific and technical literature in this and related fields of science and technology and, therefore, meet the criterion of "inventive step".

The proposed method for producing vitamin feed additives from wheat grains can be used in industrial specialized enterprises.

Anolyte solution for treating wheat grains was obtained by contact activation of a 10% sodium chloride solution at a current strength of 5 A for 12-15 minutes. This time and amperage is sufficient to obtain anolyte with specified physicochemical parameters. The current strength for obtaining a high-quality anolyte should be 5 A. If the current strength during processing is less than 5 A, then it will not be enough to acidify the anolyte to the required value and the hydrolysis process will slow down. If the current strength for processing is more than 5 A, then due to the increase in resistance, part of the energy consumption will be spent on heating the solution, which will increase the current consumption and reduce the rate of increase in pH.

If the time of washing the grain from dust and impurities is less than 4 minutes, then this time will not be enough for high-quality washing of grain, if the washing time is more than 8 minutes, this will slow down the germination technology, therefore, the optimal time for washing grain from impurities and dust is 6 minutes.

If in the claimed method for producing a vitamin feed additive from wheat during the soaking of the grain, the pH of the anolyte is less than 3.0 units, this contributes to the inhibitory effect of the processes of grain germination due to the increase in acidity of the anolyte medium, which leads to a decrease in the energy of germination of wheat grain and a decrease in the biomass and plant productivity (feed). If the pH is greater than 6.0 units, this leads to a slowdown in moisture consumption of the grain shell and increases the germination time of the feed additive, therefore, the optimal pH for the anolyte used as a lock solution for grain is 4.5 units.

If the anolyte ORP is less than 970 mV, then the stimulating effect of the anolyte on the biochemical processes of grain decreases, and the germination energy decreases, and if the ORP is more than 1110 mV, this leads to an increase in oxidative processes in solution, which slows down the activity of the enzyme systems of the grain and the yield biomass of plants, therefore, an ORP of 1040 mV is optimal for anolyte.

If the concentration of anolyte chlorine is less than 0.006 mg / l, this contributes to the active development of contaminating microorganisms, which negatively affects the quality of the feed additive. If the chlorine concentration is more than 0.01 mg / l, the increased chlorine content inhibits the germination energy, which increases the germination time of the feed additive, and also makes it difficult to use this technology in industry, so the optimal concentration of chlorine in the anolyte is 0.008 mg / l.

If the oxygen concentration in the anolyte is less than 8.3 mg / L, this significantly reduces the moisture consumption of the grain shell and, as a result, reduces the activity of grain swelling, which slows down the germination of grain and increases the germination time. If the oxygen concentration in the anolyte is more than 12.0 mg / L, then a high degree of oxygen saturation of the solution increases oxidative reactions, which slows down the enzyme systems of the grain and degrades the germination energy, therefore, the optimal oxygen concentration is 10.2 mg / L.

If the ratio of grain to anolyte is greater, this contributes to the development of unfavorable microflora, which makes it difficult to germinate, if less, saturation of the endosperm of the grain with moisture will be insufficient, which will also slow down the process of germination. Therefore, the optimal ratio of grain to anolyte, respectively, is 1: 2.

The optimal time for re-washing the grain after soaking in the anolyte is 5 minutes. Rinsing less than 5 minutes is insufficient to remove anolyte residues from the grain, if more - this helps to increase the time of the process of germination of feed.

If the germination time of the grain is less than 7 days, this contributes to insufficient accumulation of sugars and enzymes necessary for a high-quality feed supplement. If more than 9 days - the grain grows, and therefore its quality deteriorates, so the optimal germination time is 8 days.

The method of obtaining vitamin feed additives is as follows.

The washing of wheat grains is carried out with tap water for 4-8 minutes. After that, the washed grain is soaked with anolyte with a pH of 3.0-6.0 and a redox potential of 970-1110 mV, an oxygen concentration of 8.3-12.0 mg / l and chlorine of 0.006-0.01 mg / l for 3 , 5-4.5 hours at a ratio of grain to anolyte 1: 2. After that, the anolyte is removed and the grain is washed again with tap water for 3-8 minutes. Grain germination is carried out in a thin layer without using a substrate by the air-irrigation method with periodic tedding, with a total germination time of 7-9 days in natural light.

An example of the method

Take 1 kg of Bezostaya-1 wheat grain and washed for 6 min under tap water, remove the weed impurity from the grain mass, dust and place it in one layer in a low plastic container without substrate, pouring it with anolyte in the ratio of grain to anolyte 1: 2, for 4 hours at an ambient temperature of 18 ° C.

After 4 hours, the anolyte is carefully drained and the grain is washed again with tap water to remove the remaining anolyte from the grain mass, after which the stage of air-irrigation germination begins. The swollen grain is laid out in a thin layer on plastic wraps, covered with wet gauze and left at a temperature of 18 ° C and natural light, periodically irrigating the grain with water, begin to overtake the green biomass.

As a result of microbiological studies when sowing grain processed according to the proposed method, on the MPA and Chapek medium, the degree of contamination of the fungal and bacterial microflora was minimal.

Table 1 presents the difference in the energy indices of germination of wheat grain sprouted using anolyte obtained by contact activation with the indicated parameters and the prototype method (control) in five replicates. The energy of germination of wheat grain was determined according to GOST 10968-88 "Grain. Methods for determining germination energy and germination ability. " The data of biochemical studies and the content of vitamins in hydroponic greenery of wheat are presented in table 2.

On average, the difference in the energy of germination of wheat grain between the control option (prototype) and experimental (by the proposed method) was 5.4%.

The following vitamin content was determined in the green mass: B1 - 2 mg / 100 g, B2 - 0.7 mg / 100 g, B3 - 4.5 mg / 100 g, B6 - 3 mg / 100 g, E - 21 mg / 100 g.

Thus, the presented biochemical data allow us to conclude that the vitamin feed supplement is suitable for inclusion in the diet of farm animals and birds.

As can be seen, treating wheat grain with an anolyte obtained by the contact method with the stated parameters significantly reduces the germination time of grain - by 48 hours - due to increased germination energy and plant productivity, as well as an increase in biomass yield by protecting plants from contaminating microorganisms.

The proposed method for producing vitamin feed additives will reduce energy and labor costs in connection with a single use of anolyte without additional treatments with other solutions, the method does not require special equipment for germinating wheat grains.
