Description

Vegetable food composition which is effective in suppressing the absorption of heavy metals in the body and excretion of the body and health foods including the same {FOOD COMPOSITION FOR DETOXIFICATING HEAVY METAL AND HEALTH FOOD COMPRISING THE SAME}

 The present invention relates to a vegetable food composition that is effective in detoxification, such as inhibition of absorption of heavy metals in the body and excretion of the body, and a health food comprising the same.

While the industrial society has made life easier, environmental pollution has been a threat to the human living environment. Among them, heavy metal contamination of soil or water can be transferred to the human body through the food chain and accumulate, causing acute or chronic poisoning.

Heavy metals can be easily moved in vivo when organic or inorganic compounds are formed depending on the type, and have various adverse effects.

In particular, heavy metals are not easily released when they enter the body, and if the accumulation increases, they cause poisoning such as weight loss, anemia, biochemical and morphological changes of organs, brain damage, and essential inorganic elements such as calcium, iron, zinc, and selenium. Competitive action in the intestinal absorption phase reduces these contents in tissues. In addition, some toxic metals react slowly with body tissues even at relatively low concentrations, and have a slow poisoning effect.

With this social background, as a part of research to alleviate the symptoms of lead and cadmium poisoning, the effects of fibrin, protein, selenium and trace elements have been studied, and tea and green tea catechins improve renal dysfunction and normalize blood pressure caused by cadmium poisoning. Studies have been reported.

In addition, when harmful substances are introduced into the body, biotransformation proceeds in order to quickly excrete the harmful substances in the body, and eventually, the harmful substances are excreted through the body. This metabolic process is largely described in two stages: foreign substances such as environmental pollutants or drugs that are absorbed into the body are excreted in vitro by phase 1 or phase 2 reactions in the liver tissue or through both stages. Phase1 enzymes include cytochrom P450, which converts precancerous sources into highly reactive compounds through oxidation, reduction and hydrolysis of hydrophobic compounds to have reactive electrons. Phase 2 enzymes include glutathion S-transferase, UDP-glucuronosyl transferase, and guinone reductase, which convert high metabolic substances into stable ones to facilitate excretion (Liska DJ. Alter med rev 3: 187-198,1998).

Recently, many studies have been conducted on the relationship between gulcosinolates, a sulfur-containing substance in cruciferous vegetables such as cauliflower, cabbage, kale, and broccoli, as a potential cancer prevention substance. It has been reported to have an action.

As such, studies on anticancer activity associated with induction of phase 1 reaction or enzymatic activity of phase 2 are active, but studies on detoxification of heavy metals and scientific data are insufficient, and the accumulation and release of heavy metals can be induced.

The mixed amount of the active ingredient may be suitably determined depending on the purpose of use (prevention, health or therapeutic treatment). In general, in the manufacture of food or beverages, the composition of the present invention is preferably added in an amount of at least 2% by weight relative to the raw material. However, it may be used below the range according to the purpose.

There is no particular limitation on the kind of food. Examples of foods to which the substance may be added include sausages, breads, chocolates, candy, snacks, sweets, pizzas, ramen noodles, other noodles, gums, various soups, beverages, teas, drinks, alcoholic beverages and vitamin complexes. It includes both health foods and functional foods in the conventional sense.

The composition of the present invention is manufactured in various forms (tablets, powders, liquids, capsules, etc.) and can be easily consumed by males, females, young, cattle, and examinees, and workers without regard to time and place. It can be utilized to consume vegetable food composition raw materials that have been cultivated simply and continuously by organic circulation farming and have undergone low temperature drying.

In one embodiment of the present invention, the composition of the present invention is put into a triple tablet compression molding machine rectangular (not only limited to, but not limited to disk, oval, etc.) thickness of 3 to 6mm, diameter 4 to 10mm and weight 300 To 1,200 mg in the form of triple tablets. Moreover, the composition of this invention can also be shape | molded in the form of a doublet. As such, when manufactured in the form of double or triple tablets and packed in a pouch form, nutrients such as vitamins, minerals and chlorophyll may be prevented from being easily destroyed by contact with heat and light. In addition, the tablets can be prepared by cold-drying the vegetable food composition to maintain the best state as soon as harvested in the field, and can also provide the enjoyment and flavor of eating, such as to allow the ingestor to chew.

The present inventors confirmed through a test that the vegetable food composition of the present invention can effectively remove and discharge heavy metals such as lead and cadmium (see Tables 2 to 7).

Several studies have recently been reported to remove heavy metal elements in water using animal and vegetable materials as heavy metal adsorbents (Choi.si hwang jb, kwon jh, and kim hk (1998); Paeng.jj, park , ys, cheung hj, park, hs, and kim, hr (1999)). The heavy metal removal experiment of green tea began in Japan, and Professor Kimura of Nara Women's University mixed 0.5g green tea with nine heavy metals for 30 minutes and measured the adsorption rate. The adsorption rate of was found and it was reported that the adsorption rate of mercury was 94%. The experiments were performed in vitro and in vivo, and both methods demonstrated the removal of harmful heavy metals cadmium and lead (Choi.s.i lee jh, and lee s.r (1994)).

The present invention focuses on the fact that the metal ions in the waste water can be removed by binding the biomass to the biomass according to the mechanism of ion exchange index, complex ion, adsorption, and the like in the biosorbent technology in the water-soluble state. It was tested for its effectiveness against the harmful heavy metals cadmium and lead detoxification. In this experiment, the ultrafiltration membrane, which simulates the passive transport of intestinal material absorption, selectively passes materials with a molecular weight of 500 or less. This result is because the permeable membrane is made of fiber which is easily adsorbed by heavy metal.

As a result, Pb was 40-56% and Cd was 35-49% for heavy metals. In the case of mixed contamination, the removal rate of Pb was 29.7-39%, Cd was 27-41%, and green tea leaves were 35-41%.

Compared to the cadmium and lead removal effect of green tea by the membrane permeation method, the composition of the present invention showed similar efficacy as that of green tea, which can be evaluated as significant, which is useful for detoxifying or detoxifying heavy metals. Can be used.

As such, the composition of the present invention has a heavy metal detoxifying effect because the vegetable food composition cultivated by the organic circulation farming method of the three-free farming method gradually separates and dries moisture from the food through the low temperature drying method to prevent nutrition and tissue destruction of the food during the drying process. It can be considered that it is due to the complementary action of the optimal nutrient composition for detoxification of each raw material while at the same time minimizing the preservation of nutrients, colors, flavors and enzymes.

As described above, according to the present invention, it is effective in detoxifying heavy metals such as lead or cadmium, and it is possible to provide a vegetable food composition having a rich nutritional function and a health functional food including the same.

Example  One:

Organically grown moro hay, yacon, kale, barley sprouts, broccoli, celery, frosted, spinach, fresh vinegar, carrots and zucchini were washed in clean water.

The prepared organic vegetables were cut into lengths of 1 to 3 mm, respectively, and then slowly separated and dried with moisture in the food at a temperature of 20 ° C. to minimize nutrition and tissue destruction. At this time, it was individually dried at low temperature so that the moisture content was 15%.

Each material dried through the low temperature drying process was ground to a particle size of 50 mesh using a grinder.

25% by weight of each material (grind) after the crushing process (molecular weight), 12% by weight of yacon, 7% by weight of kale, 22% by weight of barley sprouts, 7% by weight of broccoli, 7% by weight of celery, 3% by weight of frost, 7 wt% of spinach, 3 wt% of fresh vinegar, 3 wt% of carrot, 4 wt% of pumpkin were mixed to make 100 wt%.

Example  2:

The mixed mixture was put into a triple tablet compression molding machine and molded into tablets having a disc thickness of 3 to 6 mm, a diameter of 4 to 10 mm, and a weight of 300 to 1,200 mg to prepare a triple tablet form.

Test Example  One:

In order to determine the detoxication effect on the harmful heavy metals (cadmium, lead) of the composition of Example 1 was carried out a heavy metal removal efficacy experiment as follows. That is, after adding the composition of Example 1 and the solid green tea leaf as a positive control to distilled water contaminated with harmful heavy metal cadmium or lead, respectively, filtration and permeation by an in vitro method using a permeable membrane (ultrafiltration membrane) considering intestinal absorption conditions.

In the case of mixed pollution, pb was 10 ppm and cd was 1 ppm which is 100 times the concentration of the water standard.

1-2-2: Heavy metal removal experiment by membrane permeation (ultrafiltration membrane)

25 ml of the filtrate that passed through the filter paper of 1-2-1 was collected and subjected to membrane permeation using an Amicon ultrafiltration cell (Amicon Division, WR Grace & Co. USA). That is, the ultrafiltration cell (ultrafiltration cell) on the molecular weight cut-after laying diaflo ultrafiltration membrane is off 500 into a coarse filtrate was filtered the above is closed and then the cap fixed to the cell while applying a 15psi pressure with N ₂ gas molecular weight Passed up to 500 materials. Since the filtrate obtained by such a device was considered to have penetrated the animal's intestinal membrane, the concentration of heavy metals was measured using an inductively coupled plasma spectrometer (ICP) without acid decomposition or solvent extraction. Three replicates were performed and the relative standard deviation was within 5%.

1-3: ICP Heavy metal content analysis

In order to quantify the filtrate passing through the above apparatus, it was treated according to Darryl and Donald's method and its concentration was measured by using ICP (Inductively coupled plasma spectrometer).

In other words, put the sample in a magnetic crucible into a 10ml H ₂ O in 10ml heater was overnight at 70 ℃ oven HNO ₃ 3 ml of (1 + 1) was added and volatilized at 120 ° C., which was left to cool, transferred to the incineration furnace, and gradually heated up to incubate at 500 ° C. for 2 hours. Then, 10 ml of HCl (1 + 1) was added, and then dissolved. The solution was transferred to a 50 ml flask, filled with deionized water, filtered and used as analytical solution. Table 1 shows the operating conditions of ICP (Inductively Coupled Plasma Spectrometer).
