Description

Horticultural fertilizers containing stevia extracts and minerals and preparation method thereof {Fetilizer containing stevia-extracts and mineral matter and}

The present invention relates to a horticultural fertilizer and a method for producing the same, which are capable of vigorously growing crops, resisting pests, and harvesting beneficial crops for the human body, and more particularly, stevia extract using ceramic balls for its molecules. It relates to the production of a penetration accelerator that can promote the transfer of functional minerals for the purpose of infiltrating crops by nanonizing.

Stevia is a low-calorie sweet ingredient in leaves and stems that is used in diet sweeteners. The taste of Stevia leaves can be tasted sweeter than sugar. It has an ingredient called stevioside, which is 200-300 times sweeter than sugar, and its calories are very low at 4 calories per gram, making it a necessity for diabetics and modern people who need a diet. In addition, stevioside is well soluble in water or alcohol, has heat resistance, and is non-toxic, so it is used as a sweetener such as sherbet, chewing gum, soft drink, and medicine.

In addition, stevia extract is used in crops to increase sugar content and promote rooting, and it is very beneficial to the human body, environment, and crops as it can decompose harmful chemicals such as chlorine, dioxins, and pesticides. .

Selenium is a kind of mineral. It is an essential trace element in the body that is known to have effects such as delaying the onset of AIDS and promoting growth in addition to anticancer. In addition, selenium is a component of glutathione peroxidase, a powerful antioxidant enzyme that removes harmful oxygen from the body, and has a function of preventing cancer by increasing immune function. Germanium is one of the carbon family elements that promotes oxygen supply to the body and activates immune cell functions to enhance immune function, removes waste products from blood vessels and normalizes blood pressure.

Crop crops produced by selenium or germanium are highly resistant to viral diseases, have good crop quality, and maintain freshness.

Until now, general selenium farming and germanium farming have been used within the range of natural penetration of minerals such as selenium and germanium, which are beneficial to humans, in crops. This method was very inefficient because the efficiency was very low compared to the amount of mineral spraying and the effect tended to penetrate when a large amount was sprayed.

Previously developed penetration accelerators had only penetration promotion action and no side effects could be expected.

The present invention for solving this problem is to provide a horticultural fertilizer containing stevia extract and minerals.

Another object of the present invention is to provide a method for preparing horticultural fertilizer containing stevia extract and minerals.

In order to achieve the above object, the present invention includes a horticultural fertilizer containing stevia extract and minerals.

In the above, the mineral is characterized in that any one or more nanoparticles selected from selenium, germanium, organic calcium, rare earth, chitosan.

In addition, the present invention comprises the steps of fermenting and ripening stevia extract; Mixing the minerals; It includes a method of producing a horticultural fertilizer comprising the step of passing the mixture through a ceramic ball filter.

Hereinafter, the horticultural fertilizer of the present invention will be described in detail.

The horticultural fertilizer of the present invention consists of a molecular nanonization process of stevia extract and mineral mixture.

Stevia extract of the present invention is dried and crushed stevia leaves and stems, soaking the crushed water in water and heated to extract the active ingredient and then concentrated stevia concentrate, and the stevia concentrate in a suitable environment to ferment and mature bacteria Aging liquors produced by the beneficial adults from. Such stevia extract has a sugar content of 200 to 300 times that of sugar but 1/90 of the calories compared to sugar, and antioxidant activity is about 5 to 7 times that of green tea.

In more detail, the stevia concentrate comprises a drying step, such as a stevia leaf, a grinding step, an extraction step and a concentration step.

The drying process is a step of sufficiently growing the stevia plant, selecting and harvesting the leaves and stem portions of the stevia plant, and the natural leaves or forced drying of the collected leaves and stem portions. The leaves and stems may be naturally dried, but forced drying with a dryer is required to quickly and uniformly dry the leaves and stems. It is usually dried at 75 ± 15 ° C for about 1 day.

Then, the stevia leaves and stems dried by the drying process are subjected to a pulverization process to grind to a predetermined size so that the effective ingredients contained in the stevia leaves and stems more effectively during the subsequent extraction process.

Next, the extraction process is a step of extracting the active ingredient from the stevia leaves and stems by heating the pulverized product pulverized in the crushing step into an extraction container containing water.

Stevia leaves and stems to be put into the extraction container may be extracted only the leaves or the active ingredient using only stevia stem, depending on the intended use, may also be extracted by mixing the appropriate amount of stevia leaves and stem.

In order to more effectively extract the active ingredient from the pulverized product, other solvents may be mixed with water, and the active ingredient may be extracted from the pulverized product at a pressure higher than atmospheric pressure.

When the active ingredient is extracted from the milled product under pressure above atmospheric pressure, the boiling point of the milled water and the like is increased, thereby effectively extracting the active ingredient contained in the milled product.

In addition, the concentration step is a step of concentrating the extract extracted from the stevia plant tissue, transfer the extract extracted in the extraction step to a concentration tank, and then heat the concentration tank to obtain a concentrate from the extract.

At this time, it is preferable to concentrate by adding heat to the concentration tank while stirring the extract of the concentration tank, which is to prevent the active ingredient of stevia to stick to the inner peripheral surface of the concentration tank.

And it is preferable to concentrate an extract liquid by applying heat to a concentration tank in the state which made the atmosphere in a concentration tank into the pressure below atmospheric pressure. This means that when the pressure in the concentration tank is below atmospheric pressure, the boiling point of the extract is relatively lower than the boiling point of atmospheric pressure, so that less energy is consumed, thereby maximizing energy efficiency and greatly reducing the time required for concentration. There is an advantage to this.

In this way, a stevia concentrate is obtained.

And the stevia aging liquid refers to a solution obtained by fermenting the stevia concentrated solution after aging for a certain time.

In the method of obtaining the aging solution from the stevia concentrate, the concentrate is fermented at a temperature of 20 to 30 ° C., and then aged for a certain period of time. And the fermentation process can be carried out by the method of fermenting the concentrate by the yeasts present in the natural state, it is preferable to shorten the fermentation period by promoting the fermentation by treating the previously cultured strain or the selected strain to the concentrate.

In the fermentation process, it is preferable to inject oxygen into the concentrate at regular intervals. Periodically injecting oxygen into the concentrate as yeast bacteria involved in fermentation are mainly aerobic microorganisms, which promotes fermentation and proliferation of yeast bacteria involved in fermentation. Providing there is an advantage that can prevent the fermentation caused by the decay bacteria during fermentation.

At this time, it is preferable to inject oxygen into the low water level of the concentrate, and more preferably, to the bottom of the concentrate. This is because oxygen supplied to the bottom of the concentrate is increased by buoyancy so that not only the yeasts present on the surface but also the yeasts growing on the bottom are energized, and the decayed bacteria can grow relatively. This is to prevent corruption by providing a clean environment.

The fertilizer for horticulture is prepared by adding minerals such as selenium, germanium, organic calcium, rare earth, or chitosan to penetrate into the stevia concentrate produced as described above for 30 minutes. After agitation, the mineral material can be made into nanoparticles of 85 ± 10 nm by passing through a ceramic ball filter network inserted into the pipe. Minerals contained in the horticultural fertilizer can be promoted in the crop by making nanoparticles.

In addition, the method of adding a substance intended to penetrate the stevia concentrate may be contained before or after fermentation.

Horticultural fertilizer of the present invention does not contain any synthetic material does not deplete the soil, stevia extracts to promote the growth of useful microorganisms in the soil to improve the adhesion of the roots of crops, improve the sugar content of fruit, infiltration The amount of penetration of minerals is much higher than the amount of fertilization when used simultaneously with the target mineral.

Therefore, according to the present invention, the horticultural fertilizer containing the stevia extract and the mineral is applied to the crop by combining the mineral with stevia, which can greatly improve the effect, and promote rooting, which was reaped at the time of the independent spraying of the stevia extract, It can increase the sugar content and prevent pests through the healthy growth of crops.
