Description

[Technical field]

[0001] The present invention relates to a liquid food or drink for promoting calcium intake, which allows humans to reliably and quickly ingest calcium, one of the important nutrients that humans should ingest from food, every day, and a method for producing the same. [Background technology]

[0002] Calcium has traditionally been one of the important nutrients for humans. This calcium is an important nutrient as a component of bones and teeth, and calcium deficiency can lead to osteoporosis due to a decrease in bone density, and the balance of remineralization can be disrupted, increasing the risk of tooth decay, so it is important to consume the required amount daily. The recommended intake for humans is 700 to 800 mg for adult men and 650 mg for women. If the daily requirement is compared to milk, which contains 110 mg of calcium per 100 g, it is said to be equivalent to about 6.5 to 7 cups for men and 6 cups for women (see, for example, Patent Document 1).

[0003] However, the invention described in Patent Document 1 involves concentrating dairy foods such as milk to efficiently ingest the calcium contained therein, but in order to achieve this, various ingredients must all be added in predetermined ratios, which is very costly to manufacture. Therefore, if this is commercialized, the cost will be passed on to the product price, resulting in a high-cost food and drink. [Patent Document 1] JP 2023-091564 A Summary of the Invention [Problem to be solved by the invention]

[0004] In recent years, the population has been aging rapidly, and people are now said to be living to 100 years old. As a result, staying active even in old age is naturally considered desirable from the perspective of quality of life (QOL).

[0005] However, as we age, our calcium absorption rate naturally declines, which in turn leads to a decline in bone density. Decreasing bone density directly affects bone strength, leading to fractures when we fall, weakening of teeth, which are important for chewing food, and calcium deficiency leading to the proliferation of bacteria in the oral cavity, which can cause periodontal disease. As periodontal disease progresses, teeth eventually fall out, the chewing function declines rapidly, and we are unable to take in enough protein and dietary fiber from our food. As a result, we are no longer able to maintain our health in line with our age.

[0006] In particular, in the case of women, calcium absorption tends to decrease following childbirth and menopause, and in addition to the decline in calcium absorption due to aging mentioned above, it is necessary for them to ingest an appropriate amount of calcium according to the stage.

[0007] In addition, children with milk allergies cannot drink milk because of the daily calcium intake, and it is difficult for them to eat small fish and other seafood every day, so they tend to be calcium deficient. Since calcium is an essential nutrient, especially for growing children, such a lack of calcium intake can become a factor that inhibits growth.

[0008] In addition, insufficient calcium intake is one of the factors that eventually lead to periodontal disease. Therefore, in recent years, with the rapid aging of society, it is important to continuously take in the necessary and sufficient amount of calcium from a young age. In other words, by eliminating one of the causes of periodontal disease, it is possible to prevent the deterioration and damage of the tooth root and periodontal ligament that accompanies it, as well as the daily hassle and reduced quality of life that accompanies the need to extract teeth and wear dentures due to the movement of the tooth root itself, and to avoid the huge cost burden of wearing implants after tooth extraction, which is important in the aging society of the future.

[0009] An object of the present invention is to provide a liquid food or drink for promoting calcium intake, which enables reliable and rapid daily intake of calcium, one of the important nutrients that humans should ingest from food, and a method for producing the same. [Means for solving the problem]

[Brief description of the drawings]

[0016] [Figure 1] FIG. 1 is a process flow diagram showing a method for producing a liquid food or drink for promoting calcium intake as an example of the present invention. [Diagram 2] 1 is a table showing examples of a method for producing a liquid food or drink for promoting calcium intake according to the present invention. [Diagram 3] FIG. 1 is an explanatory diagram showing an example of the configuration of a gallon bottle-shaped water purification device in which the liquid food and drink for promoting calcium intake according to the present invention is in the form of a cartridge refill, and which contains sufficient calcium by periodically replacing the cartridge. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0017] BEST MODE FOR CARRYING OUT THE DISCLOSURE Hereinafter, embodiments of a liquid food or drink for promoting calcium intake and a method for producing the same according to the present invention will be described with reference to the drawings.

[0018] First, the first embodiment will be described. The liquid food and drink for promoting calcium intake and the manufacturing method thereof according to the first embodiment are characterized in that eggshells are immersed in acetic acid for a certain period of time, resulting in the eggshells being dissolved in the acetic acid. Note that the "eggshells" referred to here refer to eggshells sold as packaged products at general grocery stores and supermarkets.

[0019] According to the first embodiment, the eggshell is soaked in 100% acetic acid to dissolve it, so that the liquid food and drink for promoting calcium intake according to the present invention can be produced in the shortest time. The advantages of the first embodiment are explained below. The large amount of acetic acid provides excellent preservation properties, and in addition to the recent problems of abnormal weather such as giant typhoons and torrential rains caused by linear rain bands due to global warming, and natural disasters such as large earthquakes that are difficult to predict, people are suddenly forced to live in evacuation centers for long periods of time due to man-made disasters such as conflicts between countries.

[0020] Therefore, by keeping the liquid food and beverage for promoting calcium intake of the present invention on hand at all times in preparation for such unforeseen circumstances, calcium, an essential ingestible element for humans, can be used to help maintain the health of evacuees during such long periods of evacuation.

[0021] In addition, according to this embodiment, since the amount of acetic acid is large, a sour taste may remain, but if you keep it as a regular item and dilute it with ordinary water when you actually use it, the sour taste can be diluted and it can be used without any problems.

[0022] Next, a second embodiment will be described. The liquid food and drink for promoting calcium intake and the manufacturing method thereof according to the second embodiment are substantially the same as the liquid food and drink for promoting calcium intake and the manufacturing method thereof according to the first embodiment, but is characterized in that the acetic acid used in the manufacturing process contains a predetermined ratio of an aqueous acetic acid solution.

[0023] The advantages of the second embodiment are described below. According to the first embodiment, when eggshells are dissolved in acetic acid, a strong sour taste remains, and when used in sweets or jellies, the sour taste remains, but according to the second embodiment, by further diluting the acetic acid solution, the sour taste disappears after the calcium in the eggshells is dissolved, and it can be used in sweets or jellies without any discomfort.

[0024] That is, according to the second embodiment, when added to sweets or jellies, it does not interfere with the taste of fruit as an ingredient, and it can be used freely without worrying about this point.

[0025] Next, a third embodiment will be described. The liquid food and drink for promoting calcium intake and the manufacturing method thereof according to the third embodiment are substantially the same as the liquid food and drink for promoting calcium intake and the manufacturing method thereof according to the first and second embodiments, but is characterized in that, in the manufacturing process, when utilizing the aqueous acetic acid solution used in the second embodiment, edible vinegar is used as this aqueous acetic acid solution.

[0026] The advantages of the third embodiment are described below. According to the third embodiment, vinegar that is regularly used at home is used instead of an aqueous solution of acetic acid, so that the remaining vinegar can be reused without being discarded, and eggshells that are usually disposed of as food waste can be reused without being discarded. This not only achieves resource saving by reducing waste, but also contributes to reducing carbon dioxide generated during waste treatment.

[0027] Next, the basic manufacturing steps of the method for manufacturing a liquid food or drink for promoting calcium intake according to the present invention will be described. This manufacturing process is composed of the first to third steps, specifically the first step of immersing eggshell in acetic acid or an aqueous solution of acetic acid, the second step of leaving the eggshell immersed in the acetic acid or aqueous solution of acetic acid until it dissolves from a solid state and becomes liquid and is mixed with the acetic acid or aqueous solution of acetic acid, and the third step of stirring the acetic acid or aqueous solution of acetic acid containing the eggshell in the second step to make it homogenous and filling it into a storage container. This manufacturing method will be described in more detail in the following description and examples.

[0028] In relation to the above-mentioned outline, a specific example of the manufacturing process of the method for manufacturing a liquid food or drink for promoting calcium intake will be described below. Note that the manufacturing process below is merely one example, and the volume of the acetic acid aqueous solution used, the volume of water for further diluting it, and the amount of eggshells to be soaked therein are shown as examples, and it goes without saying that various values ​​for the volumes of the acetic acid aqueous solution and water, and the amount of eggshells to be soaked therein, are within the scope of the present invention.

[0029] First, 100 cc of a commercially available aqueous acetic acid solution containing 50% acetic acid is prepared (step S1). Then, this 100 cc aqueous acetic acid solution is further diluted by adding water to obtain 200 cc of an aqueous acetic acid solution with a concentration of 25% (step S2).

[0030] Next, 20 grams of eggshells are immersed in 200 cc of the acetic acid solution diluted to a concentration of 25% (step S3). Then, it is left in this state for 4 days (step S4). As a result, the 20 grams of eggshells, which were in a solid state, are completely dissolved in the 200 cc of the acetic acid solution, and the liquid food and drink for promoting calcium intake according to the present invention is produced. Then, just to be sure, the sourness of the liquid food and drink for promoting calcium intake produced in this way is checked, and the production process is completed (step S4). EXAMPLES

[0031] The calcium content of the liquid food and drink for promoting calcium intake according to the present invention was examined when a predetermined amount of eggshell was soaked in acetic acid solutions of six different concentrations for a certain period of time and dissolved in the acetic acid solutions. In this case, a primary acetic acid solution of 500 ml (compositionally containing 29.0% to 31.0% acetic acid content) of food additive: acidulant "Acetic Acid" manufactured by Kosakai Pharmaceutical Co., Ltd. was used as the original acetic acid solution. Then, 50 g of water was added to this acetic acid solution to further dilute it to 100 g of acetic acid solution, and a predetermined amount of eggshell (10 g) was soaked in it for a certain period of time, and the amount of calcium contained in the resulting 100 ml liquid food and drink for promoting calcium intake according to the present invention was measured. The results were as follows. Note that FIG. 2 is a table showing the contents of the following respective examples of the manufacturing method of the liquid food and drink for promoting calcium intake according to the present invention. Example 1 An acetic acid solution for impregnating eggshells was prepared by diluting 20 grams of primary acetic acid solution with 80 grams of tap water, and then immersing 10 grams of eggshells in the solution and leaving it for a certain period of time until the eggshells themselves were completely dissolved.The resulting liquid food and drink for promoting calcium intake contained 555 milligrams of calcium. Example 2 An acetic acid solution for impregnating eggshells was prepared by diluting 25 grams of primary acetic acid solution with 75 grams of tap water, and then immersing 10 grams of eggshells in the solution and leaving it for a certain period of time until the eggshells themselves were completely dissolved. The resulting liquid food and drink for promoting calcium intake contained 654 milligrams of calcium. Example 3 An acetic acid solution for impregnating eggshells was prepared by diluting 30 grams of primary acetic acid solution with 70 grams of tap water, and then immersing 10 grams of eggshells in the solution and leaving it for a certain period of time until the eggshells themselves were completely dissolved. The resulting liquid food and drink for promoting calcium intake contained 714 milligrams of calcium. Example 4 An acetic acid solution for impregnating eggshells was prepared by diluting 40 grams of primary acetic acid solution with 60 grams of tap water, and then immersing 10 grams of eggshells in the solution and leaving it for a certain period of time until the eggshells themselves were completely dissolved. The resulting liquid food and drink for promoting calcium intake contained 845 milligrams of calcium. Example 5 An acetic acid solution for impregnating eggshells was prepared by adding 55 grams of tap water to 45 grams of primary acetic acid solution and further diluting it to prepare an acetic acid solution for soaking and dissolving eggshells. When 10 grams of eggshells were soaked in this solution and left for a certain period of time until the eggshells themselves were completely dissolved, the resulting liquid food and drink for promoting calcium intake contained 975 milligrams of calcium. Example 6 An acetic acid solution for impregnating eggshells was prepared by diluting 50 grams of primary acetic acid solution with 50 grams of tap water, and then immersing 10 grams of eggshells in the solution and leaving it for a certain period of time until the eggshells themselves were completely dissolved. The resulting liquid food and drink for promoting calcium intake contained 1,220 milligrams of calcium.

[0032] Next, an embodiment in which the liquid food and drink for promoting calcium intake according to the present invention is attached to an apparatus for purifying tap water and producing drinking mineral water will be described. Fig. 3 is a schematic diagram showing an improvement of a drinking water supplying apparatus in which the liquid food and drink for promoting calcium intake according to the present invention is attached to an apparatus for purifying tap water and producing drinking water, and a predetermined amount of water is measured from the water tank into a container such as a cup while containing calcium contained in the liquid food and drink for promoting calcium intake according to the present invention at a desired ratio.

[0033] The configuration of this embodiment will be described below with reference to Fig. 3. A tap water purification tank 100 for supplying tap water is provided at the top of the calcium-containing purified water supplying device 10. A main supply pipe 110 is provided at the bottom of the calcium-containing purified water supplying device 10, and a calcium intake promoting bottle cartridge 200 and a bottle cartridge holder 210 for holding the bottle cartridge are provided on one side of the calcium-containing purified water supplying device 10.

[0034] A sub-supply pipe 220 extends from the bottle cartridge holding unit 210 and supplies each liquid to the calcium-containing / agitating operating device 300 together with the main supply pipe 110. On the side of the calcium-containing / agitating operating device 300, there are provided the calcium-containing / agitating operating device 300 and the calcium-containing / agitating operation control unit 400 for mixing the mineral water supplied to the calcium-containing / agitating operating device 300 and the diluted calcium intake supporting liquid supplied from the bottle cartridge holding unit 210 filled with the diluted calcium intake promoting liquid food or beverage according to the present invention through the sub-supply pipe 220 at a certain ratio and sufficiently stirring and mixing them at a certain ratio.

[0035] With regard to the bottle cartridge holding portion 210 filled with the above-mentioned calcium intake promoting bottle cartridge 200, when the content of the bottle cartridge holding portion 210 runs out, it is possible to replace it with a new bottle cartridge 200 filled with a calcium intake promoting bottle cartridge 200, thereby making it possible to continuously supply calcium from the mineral water without interruption.

[0036] The calcium-containing / agitating operation control unit 400 is for controlling the operation of the calcium-containing / agitating operation device. The calcium-containing / agitating operation control unit 400 is provided with a display / operation unit 410 having a controller, a display, a switch, and the like, as a part thereof, and by appropriately operating this display / operation unit 410, calcium-containing drinking water having an optimal calcium content ratio is made to flow down through a calcium-containing purified water nozzle 450 provided on the lower side of the calcium-containing purified water supply device 10. Thus, calcium-containing drinking water containing an optimal amount of calcium can be constantly provided in a cup 550 placed inside the receiving container 500.

[0037] Next, other embodiments will be described. As a preferred example, the present invention will be used to make a cake that everyone likes, such as a birthday cake. Specifically, when making a whole cake with a diameter of 15 cm, a sponge is baked using one egg per cake, and the shell of one egg (10 g) is immersed in 100 g of acetic acid solution, and syrup and lemon juice are added to the liquid in which calcium has dissolved, which is then spread on the sponge, and the entire sponge is coated with fresh cream, thereby making it possible to produce a cake containing an appropriate amount of calcium to be ingested during meals.

[0038] By enjoying this cake together as a family, everyone can take in the necessary and sufficient amount of calcium while eating, including growing children, fathers and mothers who are busy with daily work and housework, grandparents and great-grandparents who are getting older and need to prevent the onset of osteoporosis caused by calcium deficiency, and also women who have just given birth and women who have passed menopause.

[0039] Next, examples of target foods using the liquid food and drink for promoting calcium intake according to the present invention are as follows. For example, beverages include ordinary drinking water, juice, tea or black tea to be consumed with snacks, coffee, chilled sports drinks in plastic bottles, barley tea, and green tea (such drinks can be used as a measure against heatstroke in midsummer, and at the same time, they can fulfill the role of supplying calcium necessary for strengthening bones to improve skills during exercise, as well as activities and tasks under the hot sun.), confectionery includes jelly, gummies, cookies, chocolate, cakes, baked goods, etc., seasonings include soy sauce, salt, miso, soup stock, vinegar, etc., dairy products include yogurt, cheese, etc., retort foods include curry, Chinese food, stew, etc., and instant foods include noodle foods such as ramen and yakisoba. Instant foods are particularly effective when people who are busy on a daily basis and cannot eat meals containing sufficient nutrition can consume calcium at the same time as eating foods that are prepared or provided in the event of a disaster.

[0040] In addition, the liquid food and drink for promoting calcium intake according to the present invention has the following further advantages. Specifically, one example is a case where a parent gives a calcium supplement to a child. It is difficult for the parent, as a purchaser, to objectively determine whether the ingredients and quality of such supplements are appropriate, and it is also difficult to properly determine at a glance the actual calcium content of the supplement given to the child each time.

[0041] However, in the case of the liquid food and drink for promoting calcium intake according to the present invention, for example in the second embodiment, when 50 grams of water was added to a commercially available mixture of acetic acid: food additive: acidulant (manufactured by Kosakai Pharmaceutical Co., Ltd., acetic acid content 29.0% to 31.0%), 10 grams of eggshell was immersed in the mixture, and the mixture was left to dissolve for four days, it was found that 1220 milligrams of calcium was contained in 100 milliliters. By using this, it is possible to ingest the same amount of calcium as one bottle of milk with about one tablespoon, and it can be understood that it becomes easy to objectively and intuitively grasp the amount of calcium intake.

[0042] In other words, with the liquid food and drink for promoting calcium intake according to the invention, in the above-mentioned case, it is possible to intuitively and mentally memorize and understand that approximately one tablespoon is equivalent to the amount of calcium contained in one eggshell, or in other words, 200 milliliters of milk, and therefore it is possible to give the appropriate amount of calcium to a child without fail, thereby eliminating any anxiety about giving the above-mentioned supplements to children.

[0043] In addition, since the calcium itself is made from dissolved eggshells, it is a natural food, which helps to alleviate the anxiety parents have when giving supplements to growing children without knowing what artificial ingredients they may contain.

[0044] Furthermore, even in cases other than giving the above-mentioned supplements to children, for example, in order for children or adults to ingest calcium from food every day, they would have to purchase, cook, and eat whole dried sardines, Japanese mustard spinach, hijiki seaweed, tofu, etc. every day without fail. In today's fast-paced world, purchasing such foods every day and carefully cooking and eating them would be a heavy time and financial burden.

[0045] However, the liquid food and beverage for promoting calcium intake of the present invention makes it possible to avoid such problems and achieve the necessary and sufficient daily intake of calcium, which is essential to prevent the various adverse effects caused by calcium deficiency, while significantly reducing the time and financial burden.

[0046] In addition, for elderly people and others with reduced chewing ability, it is desirable to fully digest small fish bones and other foods to obtain calcium into the body; however, as the digestive function declines with age and chewing ability declines, the body often ends up excreting the bones as they are, and is therefore unable to obtain the desired amount of calcium.

[0047] In addition, coupled with the above-mentioned decrease in masticatory power, it is quite conceivable that due to bias in food preferences, komatsuna, hijiki, tofu, etc. will be left uneaten. However, for example, by mixing the liquid food and drink for promoting calcium intake according to the present invention with soft food with extremely high fluidity, such as vegetable soup, and having such elderly people eat it, there is no need to completely digest and absorb the calcium contained in the solid form of the above-mentioned small fish, etc., in the digestive organs, and the calcium contained in the liquid form can be absorbed naturally and efficiently in the digestive organs.

[0048] In this respect, the liquid food and drink for promoting calcium intake according to the present invention can be said to have an extremely excellent advantage in terms of ensuring necessary and sufficient daily calcium intake compared to other calcium-containing foods.

[0049] Finally, the following describes how the inventor of the present invention came up with the idea for the present invention. The inventor of the present invention runs a cake shop, and while working, he wondered if there was an effective way to use eggshells, so he soaked 100 grams of eggshells in 1 liter of vinegar, left it for 7 days, and investigated the composition of the solution.

[0050] As a result, it was found that 100g of vinegar contained 1120mg of calcium. It is known that one glass of milk contains 227mg of calcium, but when considering vinegar with dissolved calcium (eggshell vinegar), one tablespoon (15mg) contains 168mg. This means that 20mg of eggshell vinegar can provide the same amount of calcium as one glass of milk.

[0051] The Ministry of Health, Labor and Welfare has set the recommended amount per adult at 700mg to 800mg for men and 650mg for women. It is said that one glass of milk contains 30% of the daily calcium requirement, so one should drink one glass a day. However, in modern times, there are an increasing number of people who are allergic to milk or who get stomach rumbling when they drink milk. Therefore, we believe that the eggshell vinegar that we have produced this time can be consumed by such people without any problems.

[0052] Further research revealed that half of the Japanese population is calcium deficient. Almost all of the half are women. Because calcium deficiency is commonplace, they develop osteoporosis when they get older. Again, almost all of the people are women. I also focused on what to do to prevent a decrease in bone density as people get older.

[0053] To solve this problem, it is necessary to ingest calcium from childhood. In addition to this, moderate exercise that puts stress on the bones is also effective. It has been found that ingesting sufficient calcium from the developmental stage is particularly beneficial for women. Specifically, women need to ingest sufficient calcium by around the age of 20. Calcium decreases with each menstruation and pregnancy and childbirth, and calcium decreases especially after menopause. It is clear that the present invention can make a significant contribution to solving such problems specific to women.

[0054] The inventor of the present invention has focused on the advantages of the present invention from a further perspective, which will be explained below. It is said that one of the main factors that cause calcium deficiency in Japanese people is that tap water in Japan is soft water. The reason for this is that soft water has no unpleasant taste and can be used to make tea or cook rice.

[0055] Of course, rain is also soft water. Unfortunately, vegetables grown with that soft water also lack calcium. On the other hand, countries with hard water are said to be unsuitable for cooking because the water contains calcium. For this reason, people seem to use both bottled water and tap water.

[0056] Taking into consideration the above factors, the inventor of the present invention conducted various investigations and considered selling vinegar with calcium dissolved in it, but realized that the vinegar had lost its sourness and was not tasty.

[0057] The inventors of the present invention then realized that if the sourness had been removed, then liquid food or beverage in this state could be used as a liquid food or beverage for promoting calcium intake and could be mixed with sweets or seasonings without causing any unpleasant sensation.

[0058] Specifically, one example is konnyaku jelly using the liquid food or drink for promoting calcium intake according to the present invention. The reasons for using konnyaku jelly here are, first, that it is a healthy snack. Second, that it is a snack that mothers can safely give to their children. Third, for example, many young women who are concerned about their figure carry commercially available konnyaku jelly in their bags and eat it when they feel a bit hungry.

[0059] In addition, the inventor of the present invention aims to enable various people, regardless of age or gender, to take in the amount of calcium they need every day in a natural way by using sweets and seasonings containing the liquid food or drink for promoting calcium intake according to the present invention. Specifically, he thinks that a sweet that allows one to take in the amount of calcium equivalent to one glass of milk with one cookie is preferable.

[0060] In addition to the above-mentioned konnyaku jelly and other sweets, the present invention can also be applied to liquid foods and beverages for promoting calcium intake, such as adding a required amount of the present invention to instant curry or seasonings such as miso, which allows one to ingest the same amount of calcium as one glass of milk in one glass of miso soup.Furthermore, it is considered to be a preferable form for allowing one to ingest the same amount of calcium as one glass of milk by drinking one bottle of sports drink, which is essential as a measure against heatstroke in midsummer.

[0061] When applying the present invention to the above-mentioned konnyaku jelly, since vinegar contains 10% to 20% acetic acid, the acetic acid dissolves calcium, so by adding 30% to 50% acetic acid to boiled tap water, soaking 10% eggshells in it, and leaving it for about a week, and then mixing it with konnyaku jelly, it is possible to produce konnyaku jelly that can exert the effects of the present invention.

[0062] Konnyaku jelly is generally 20g to 25g per piece, and if you put the calcium of one glass of milk in one piece and eat one every day, you can make konnyaku jelly that contains the calcium of one glass of milk. In other words, if you eat three pieces of this konnyaku jelly every day, you can get the daily calcium intake recommended by the Ministry of Health, Labor and Welfare. At first, I thought of soaking eggshells in vinegar, but it doesn't have to be vinegar.

[0063] As explained above, the liquid food and drink for promoting calcium intake and the manufacturing method thereof according to the present invention can solve all of the problems related to the present invention described above. Note that the mass percentages and volume percentages, specific materials, and specific dilution rates in the above-mentioned embodiments and examples are merely illustrative, and needless to say, they can be appropriately changed within the range in which the effects of the present invention can be obtained.
