Background
Calcium is a main element composing human bones, and is sufficient to provide nutrition for the calcium, thereby playing an important role in maintaining bone health of people in various stages of life. Calcium deficiency can lead to a variety of diseases and complications in the human body. Specifically, for different specific crowds, if the human body is insufficient in calcium intake, the middle-aged and the elderly are easy to have symptoms such as fracture, cramp, bone pain, osteoporosis and the like; the intake of the pregnant woman lacking in calcium is easy to induce muscle spasm, waist soreness and backache, absentmindedness and severe gestational hypertension; the lack of calcium in teenagers and children can affect the development of bones, inappetence, and the like. Therefore, adequate calcium intake has been a fundamental measure for maintaining bone health and preventing bone diseases. As such, children, pregnant women, and the elderly are also recommended by modern medicine as specific populations for calcium supplementation. Along with the improvement of the living standard and health consciousness of people, the cognition of people on health-care food is gradually clear, and timely calcium supplement can gradually become daily living habit of people. It is expected that more and more calcium preparations will enter the market, the calcium preparation market is expected to be further subdivided, and a good development opportunity is provided for new enterprises. Therefore, the development of the easily-dispersed and easily-absorbed calcium supplementing composition and the preparation method thereof have broad prospects and great significance.
The ideal calcium supplement should have the characteristics of convenient eating, fast digestion, good absorption, less side effects and the like. Currently, the main stream of calcium-supplementing preparations on the market still mainly comprises "molecular calcium", such as calcium carbonate, calcium phosphate, calcium citrate, and the dosage forms of molecular calcium products include: chewable tablets, capsules, effervescent tablets, granules, medicinal granules and the like. Although molecular calcium has the advantages of easily available raw materials, low cost and the like, the molecular calcium cannot be directly absorbed by human bodies, and can be converted into absorbable calcium by digestive juice and enzyme, so that the absorption rate is very low, the effective utilization rate of the calcium is lower than 40%. For example, the digestion and decomposition rate of calcium citrate in vivo depends on factors such as the size, structural compactness, surface properties (morphology, wettability and the like) and the like of the calcium citrate, and calcium citrate molecules with smaller size and larger specific surface area are easier to disperse into intestines and stomach to be absorbed, and finally the absorption and utilization rate of calcium ions of a human body are improved.
As disclosed in chinese patent application 202110130168.4, a calcium supplementing composition and a method for preparing the same, the composition comprising the following components: stachyose, casein phosphopeptide, calcium carbonate, L-calcium lactate, calcium aspartate, mushroom powder and maltodextrin, the invention has the advantages of good calcium supplementing effect, simple preparation process and excellent product stability and solubility, but the calcium supplementing composition provided by the application has low absorptivity and is difficult to increase bone density.
As further disclosed in chinese patent application 201510819478.1, a calcium lactate granule composition suitable for infant calcium supplementation and a method for preparing the same are disclosed, which comprises the following components in parts by weight: 50-90 parts of calcium lactate, 0.5-1 part of zinc citrate, 0.3-1 part of ferrous lactate, 5-10 parts of casein phosphopeptide, 350-400 parts of glucose, 20-40 parts of fructo-oligosaccharide, 5-10 parts of L-malic acid and 10-30 parts of edible traditional Chinese medicine granules for strengthening spleen and tonifying qi, and the preparation method comprises the following steps of: A. preparing edible Chinese medicinal material granules, mixing the raw materials and sterilizing; compared with the prior art, the invention effectively combines the calcium supplement agent and the traditional Chinese medicine, realizes the combination of Chinese and western medicine and food and medicine, promotes the absorption of calcium, iron and zinc by casein phosphopeptide, promotes the digestion and absorption of zinc citrate, promotes the absorption and metabolism by L-malic acid, and promotes the digestion and absorption by the edible traditional Chinese medicine components of strengthening spleen and supplementing qi, and the citrate, the malic acid, the lactate and calcium ions are easy to form metastable calcium salt, inhibit the generation of insoluble calcium, better promote the absorption of calcium, iron and zinc by infants, and achieve the effect of 1+1 > 2, but the effect of increasing the absorption rate of calcium and the bone density is still unsatisfactory.
Aiming at the problems of poor taste, low dispersity, difficult swallowing, low absorptivity, difficult bone density increase and the like of various health care products for improving bone density, the invention aims to find a calcium micro-granulation composition and a preparation method thereof, so that the calcium micro-granulation composition is more convenient and fast to drink or eat by consumers, is easier to orally swallow, and is easier to disperse and absorb.

The adhesive is polydextrose.
In some preferred embodiments, the mass ratio of calcium citrate to polydextrose is from 25:2 to 8.
As some preferred embodiments, the readily dispersible, readily absorbable calcium powder compositions have a moisture content of 0.5 to 8 weight percent.
As some preferred embodiments, the easily dispersible and easily absorbable calcium powder composition further comprises 20-40 parts of filler and 1-3 parts of suspending agent;
the filler is erythritol;
the suspending agent is agar.
As some preferred embodiments, the easily dispersible and easily absorbable calcium powder composition comprises the following components in parts by weight:
35-55 parts of calcium citrate;
5-20 parts of polydextrose;
20-40 parts of erythritol;
0.5-3 parts of calcium-promoted absorbent;
1-3 parts of agar;
the calcium-promoted absorbent is a mixture of casein phosphopeptide, whey protein hydrolysis peptide and Lycium barbarum polysaccharide in a mass ratio of 1:1:1.
The application also provides a preparation method of the easily-dispersible and easily-absorbable calcium powder composition, which comprises the following steps:
(1) Preparing an adhesive: sieving the adhesive, dispersing the adhesive with the formula amount in purified water with the formula amount of 40%, and stirring to dissolve the adhesive into an aqueous solution;
(2) Granulating: weighing and loading a calcium source, a suspending agent and a filler in the dosage of the formula into a stirrer, and uniformly mixing to obtain a mixture; standby; granulating the mixture by using the aqueous solution prepared in the step (1) on a fluidized bed, drying, and sieving once to obtain pre-micro granulating powder;
(3) Mixing the pre-micro granulation powder obtained in the step (2) with a calcium promoter, sieving again, and discharging to obtain a calcium micro granulation composition;
the number of the sieves described in the above step (1) is 10 to 30 mesh, preferably 20 mesh.
The granulation conditions in the step (2) are as follows: the temperature is 45-65 ℃; the atomization pressure is 0.12Mpa-0.3Mpa, and the air inlet frequency is 20 Hz-35 Hz; the number of the first pass is 10-30 meshes, preferably 20 meshes; the number of the re-screening is 10-30 meshes, preferably 20 meshes.

When the water content of the micro-granulation is 0.5-8%, a more uniform granulation morphology can be obtained in the micro-granulation.
The application uses calcium citrate as a calcium source:
calcium citrate, commonly referred to as tricalcium citrate, is also known as calcium citrate. As an organic acid calcium, the calcium carbonate has higher solubility and bioavailability than inorganic acid calcium such as calcium carbonate, tricalcium citrate and the like, has no stimulation to intestines and stomach, does not need to be neutralized by gastric acid, and can be directly absorbed by human body. For example, tan Hui provides good therapeutic effects on osteoporosis by calcium citrate, which does not produce CO in the gastrointestinal tract 2 Therefore, the adverse reactions such as dyspepsia, abdominal distension, constipation and the like are reduced, and the traditional Chinese medicine composition is particularly suitable for long-term use of senile osteoporosis patients. Calcium citrate has been widely used as a food additive and a nutrition enhancer, and is the first choice for food-based calcium supplements.
Erythritol is used as a filler or sweetener in the present application:
erythritol is a novel nutritive sweetener and is characterized by good heat stability, small hygroscopicity, low freezing point, low calorific value and cool feel. The characteristics of the composition lead the composition to be widely applied to the fields of foods, medicines, cosmetics and the like. Wherein, because the erythritol has very low calorie and is called as a sweetener with zero calorific value, the erythritol can be used for producing various low-calorie health-care foods and beverages; in the field of medicine, erythritol can be used as a flavoring agent of medicines and an excipient of tablets, can effectively improve the taste of products, and is also beneficial to forming uniform granulation in the fluidized bed granulation process.
Casein phosphopeptides are used as one of the calcium-promoted absorbers:
casein phosphopeptide (CPP) has been widely studied as a known phosphopeptide calcium-supplementing preparation, its calcium absorption-promoting activity and mechanism. The absorption pathway of calcium in mammals can be divided into the saturated transcellular pathway (i.e., active absorption) and the cellular alternative pathway (i.e., passive absorption), and the main way of calcium absorption depends on the body's calcium content. The phosphopeptide has a remarkable effect on binding metal ions due to the special negative charge structure, calcium ions are easy to be combined with the phosphopeptide to form a peptide-calcium complex, the peptide-calcium complex is integrally transported into cells through a small peptide transportation path, the small peptide is used as a carrier for calcium transportation, and the calcium absorption is promoted and is not dependent on TRPV6 calcium ion channels and 1, 25-dihydroxyvitamin D3 to be absorbed by human bodies, so that the function of substituting the vitamin D3 can be achieved to a certain extent. Meanwhile, various research data show that the lycium barbarum polysaccharide and the whey protein hydrolysis peptide have the same efficacy as CPP, and can promote the absorption of free calcium by human bodies. Therefore, the calcium absorption and diffusion transportation are promoted by adding the calcium absorption promoter, so that the absorption rate of the calcium is increased.
It has the following advantages:
1. the casein phosphopeptide can keep calcium in a free state and promote the passive absorption of calcium; 2. promoting the absorption and utilization of other divalent mineral nutrients such as iron, zinc and the like, and overcoming the potential adverse effect of calcium on the absorption of iron and zinc; 3. the casein phosphopeptide can also weaken the action of osteoclasts and inhibit bone resorption, thereby improving the bone calcium content; 4. can also combine calcium ions at the caries site, lighten the demineralization of enamel and achieve the effect of anticarious. Alternatively, the whey protein-hydrolyzing peptide and the matrimony vine polysaccharide also have the effect of promoting calcium absorption.
The application uses polydextrose as a binder:
has the following advantages: 1. changing physical and chemical properties of the substance; 2. changing the reactivity of the envelope; 3. has low calorie health food characteristics; 4. has necessary volume, improves the taste of food, improves oily taste, and is favorable for granulation and dispersion.
Compared with the prior art, the application has the following beneficial effects:
1. according to the calcium powder composition, as the raw material calcium citrate is ultrafine powder capable of passing through a 1250-mesh sieve, the obtained micro-granulation has proper granulation structure and size, and a proper fluidized bed drying process, so that the stability is higher and the granulation dispersity is better; and the effect of remarkably improving the calcium absorption rate of the human body is achieved by adding a proper amount of calcium-promoting absorbent and compounding.
The calcium powder composition provided by the application has reasonable components and proportions, and has good effect of increasing bone density as a calcium supplementing product;
