    [0001] The present invention is related to but not dependent of the following foreign patent applications: Foreign Patent Documents (application number, filing date, publish date, country code): [0001] 99116298.6  7/20/1999 03/22/2000 CN. 99117294.9 12/17/1999 07/26/2000 CN. 99117295.7 12/17/1999 07/26/2000 CN. 99124691.8 12/30/1999 08/23/2000 CN. BACKGROUND OF THE INVENTION
    [0002] The present invention concerns a process for producing nutritional supplements rich in organic trace elements using soilless culture of plant sprouts and seedlings. In particular, the process of this invention uses the plant's own natural ability to convert inorganic trace elements into organic form, producing a superior type of organic nutritional supplements. [0002]
    [0003] The primary source of food and nutrition for human comes from agriculture products. However, for a very long time, the agricultural research and development mainly focus on refining traditional agriculture techniques with modern technologies such as fertilizer and genetic engineering. Too often the goal of these developments is simply to increase production while ignoring the nutritional quality of the products. Abundant studies have shown that agriculture products produced with these technologies lack sufficient trace elements the human body needs or may benefit from such as iron, zinc, copper, selenium, chromium, iodine and germanium. At the same time, modern medical and biological researches have highlighted the significant physiological effect of trace elements on human health, which led to a new breed of nutritional supplement products that contain trace elements. [0003]
    [0004] Currently, the use of trace elements in nutritional supplements can be categorized into four types: 1) inorganic salt such as ZnSO[0004] 4 and FeSO4; 2) simple organic compound such as FeC6O8H7 and ZnC6H12O7; 3) organic complex compound such as trace element amino acid compound; 4) natural organic form trace element such as zinc enriched brewers dried yeast. The disadvantages of the first two types of supplements include: low dosage use cannot satisfy human nutritional need, toxic when used in high dosage, prone to oxidation, hygroscopicity and precipitation in a mixture of different salts and/or compounds. While the last two types of supplements overcome the disadvantages of the first two, they often require complex and expensive laboratory and industrial process to manufacture.
    [0005] The concept of this invention is based on the studies of biogeochemistry and the new discipline of agricultural biogeochemistry pioneered by the inventor in China, which calls for the research and development of new agriculture products rich in trace elements essential to human health. The goal of this invention is to provide a new method to produce natural organic form trace element nutritional supplements that solves the problems of various current technologies mentioned above. Specifically, its process shall be simple, non-toxic, inexpensive and suitable for a wide range of application environment from common household to large-scale manufacture. [0005] BRIEF SUMMARY OF THE INVENTION
    [0006] The present invention provides a process for producing nutritional supplements rich in organic trace elements essential to human health using soilless culture of plant sprouts and seedlings. The process of this invention uses a certain concentration range of the inorganic salt solution of the target trace element(s) to saturate the selected plant seeds. The saturated seeds are moved to a soilless culture environment to germinate. The sprouts are then rinsed, peeled, steamed, dried, ground and packaged for use as nutritional supplements or other food and drug manufacture additive. In addition, the young seedlings can be used directly as vegetable. The primary advantage of this invention is the enriched trace element content, such as iron, selenium, germanium, zinc and chromium, in the sprouts and seedlings is mainly in organic form, which is the result of the natural organic conversion of these trace elements from their inorganic form during the germination. Such form of organic trace element is non-toxic and much easier for the human body to digest and absorb. Further, the trace element concentration in the sprouts and seedlings can be effectively controlled. [0006] DETAILED DESCRIPTION OF THE INVENTION
    [0007] The present invention provides a process for producing nutritional supplements rich in organic trace elements using soilless culture of plant sprouts and seedlings, comprising the following steps: [0007]
    [0008] a) In room temperature of 20°C. to 28° C., completely submerge the selected seeds in the inorganic salt solution of the target trace element(s) for 4 to 6 hours depending on the type of seed used and the temperature. For every 100 g seeds, use 120 ml solution. The goal is to saturate the seeds with the inorganic trace element solution in preparation for the germination process. [0008]
    [0009] b) Transfer the seeds from the saturation container to soilless culture devices and use tap water or purified water as initial moisture. Then place the populated devices into a darkened and 20° C. to 28° C. temperature controlled culture container or room to allow the seeds to sprout and grow. Spray the same seed saturation solution onto the sprouts and seedlings twice a day to replenish moisture. [0009]
    [0010] c) Allow the seeds to sprout to 1 to 1.5 cm in height. This is often equal to 1 to 3 days of culture in the said environment. Harvest the sprouts from the culture devices, soak and rinse in purified water or ion-free water. Optionally, steam cook and peel the sprouts to remove undesirable taste. Then dry and ground the sprouts into a powder form composition for packaging. Alternatively, if soybeans is used in step a, a milk-like extract can be produced by grinding the sprouts with drinking water then filtering out remaining sediment. [0010]
    [0011] d) To produce seedlings as vegetable, allow the seedlings to grow for 3 to 6 days as desired. Remove the seedlings from the culture devices, soak and rinse in tap water or purified water. [0011]
    [0012] In step a, the pH of the saturation solution is adjusted to between 5 and 6. The target trace element concentration and the type of inorganic salt or compound used in the saturation solution are: a 500 to 3000 μg/g iron concentration solution of FeSO[0012] 4.7H2O; or a 5 to 100 μg/g selenium concentration solution of Na2SeO3; or a 50 to 1000 μg/g germanium concentration solution of GeO2; or a 500 to 3000 μg/g zinc concentration solution of ZnSO4.7H2O; or a 10 to 1000 μg/g chromium concentration solution of CrCl3.7H2O; or a mixture of 5 to 100 μg/g selenium concentration and 50 to 1000 μg/g germanium concentration solution of Na2SeO3 and GeO2.
    [0013] The trace element concentration, volume and the pH of the saturation solution and the length of the saturation process are essential to the successful germination of the seeds and the desirable level of organic trace element content in the sprouts and seedlings. If these parameters fall out side the above specified range, it may hinder the germination or reduce the nutritional value of the product. [0013]
    [0014] The types of seeds may be used in this invention include soybeans, black beans, red beans, green beans, daikon seeds, wheat and any other types of plant seeds that suit the needs of the desired diet or the particular manufacturing process. Similarly, although this invention focused on five trace elements, other types of trace elements essential to human health are also applicable. [0014]
    [0015] Post-process data were collected using the powder form composition. The data shows the trace element content in the powder after the enrichment process is significantly higher than that of before. The organic form trace elements content in the powder after the enrichment process is also much higher than that of inorganic form trace elements. Further, the trace element content in the powder is roughly proportional to the trace element concentration of the saturation solution used in step a and b. [0015] EXAMPLE 1
    [0016] Soybeans are used to produce the powder form composition enriched separately with zinc, iron, selenium, germanium and chromium. The result of the process is shown in Table I below. [0016] TABLE I Zinc Iron Selenium Germanium Chromium (III) Solution (μg/g) 600 1000 2000 1000 1500 2000 10 50 75 500 750 250 500 750 Seeds (μg/g) 26.5 57 0.0583 4.6 2.6 Powder (μg/g) 540  900 1490  800 1250 1500 8.9 35 57.6 224 432 147 290 540 EXAMPLE 2
    [0017] Black beans are used to produce the powder form composition enriched separately with zinc, iron, selenium and chromium. The result of the process is shown in Table II below. [0017] TABLE II Zinc Iron Selenium Chromium (III) Solution (μg/g) 1000 2000 1000 1500 2000 10 50 75 250 500 750 Seeds (μg/g) 46 72 0.0086 1.6 Powder (μg/g)  920 2020  870 1500 2600 7.73 26 52.8  99 270 550 EXAMPLE 3
    [0018] Green beans are used to produce the powder form composition enriched separately with zinc, iron, selenium, germanium and chromium. The result of the process is shown in Table III below. [0018] TABLE III Zinc Iron Selenium Germanium Chromium (III) Solution (μg/g) 600 1000 2000 1000 1500 2000 10 50 75 500 750 250 500 750 Seeds (μg/g) 24 37 0.0605 4.67 4.17 Powder (μg/g) 540  740 1400  850 1450 1900  9 26 52.3 340 581 150 310 470 EXAMPLE 4
    [0019] Soybeans are used to obtain the organic conversion rate of zinc and selenium. Add 1 gram of the powder form composition in 99 ml distill water and place the mixture in a 12,000 rpm electronic agitator to thoroughly break down the cell wall. Use a microscope to verify that more than 95% of the cell walls are broken down. Then pour 100 ml of the mixture in a dialysis bag and place the bag in a 250 ml ion-free water environment to dialyze in low temperature for at least 48 hours. The total zinc (or selenium) content in the powder minus the zinc ion content in the dialysis solution equals the amount of zinc in the powder in organic form. The result is shown in Table IV below.
