Problems solved by technology

[0003] Relevant literatures report the production methods of calcium lactate, calcium acetate, calcium gluconate, calcium citrate, calcium citrate-calcium malate using eggshells, but all of them are chemically synthesized or chemically extracted lactic acid after biological fermentation , acetic acid, gluconic acid, citric acid and malic acid, the obtained organic calcium has a single component, which is not conducive to long-term use, and its solubility in water is limited
However, there is no relevant report on the new method of producing highly water-soluble compound organic calcium by using natural acidic fruit juice, eggshell, etc.

Embodiment 1

[0020] Take 100g of fresh lemon juice and heat it to 70°C, when the pH=1-2. The calcined eggshell powder was gradually added under stirring, and when the pH=7, a total of 3.10 g of the eggshell powder was added. The obtained translucent liquid was dried at 80° C. to obtain 8.96 g of a light yellow-green solid with a calcium content of 24.7% as tested. 1 g of this solid can be completely dissolved in 10 ml of water, and no precipitate is formed. After being placed for a long time, the appearance and smell have not changed.

Embodiment 2

[0022] Take 100g of fresh orange juice and heat it to 65°C, when the pH=1-2. The calcined eggshell powder was gradually added under stirring, and when the pH=7, a total of 2.83 g of the eggshell powder was added. The obtained translucent liquid was dried at 80° C. to obtain 10.58 g of an orange-yellow solid, with a calcium content of 19.1% as tested. 1 g of this solid can be completely dissolved in 10 ml of water, and no precipitate is formed. After being placed for a long time, its appearance and smell have not changed.

Embodiment 3

[0024] Take 100g of fresh mandarin orange juice and heat it to 75°C, at this time the pH ≈ 2. The eggshell powder obtained by calcining was gradually added under stirring, and when the pH=7, a total of 1.75 g of the eggshell powder was added. The obtained translucent liquid was dried at 80° C. to obtain 9.47 g of a light brown solid with a calcium content of 13.2%. 1 g of this solid can be completely dissolved in 10 ml of water, and no precipitate is formed. After being placed for a long time, its appearance and smell have not changed.

Abstract

A new preparing high dissolved complex organic calcium method using acid fruit juice and eggshell as raw materials which is that cleaning, triturating and drying the eggshell, then calcining to eggshell powder, preparing and getting fruit juice by fruits flayed, enucleated, extracted and filtrated; dissolving eggshell powder into fruit juice with mixing at some temperate to make fruit juice of neutrality from acid, where the most suitable quality is 1~5g per fruit juice 100g; putting reacted resultant into petri dish, heating and drying to get calcium preparation at 80 deg.C, or packaging to liquid product directly without drying. The method uses natural fruit juice in place of lactic acid, acetic acid, gluconic acid, citric acid and malic acid artificial composed or fermentation, from which the product can solved in water very easy, contains mass calcium and many kinds natural benefit ingredient, and is propitious to absorb and take for long time.

Description

technical field [0001] The invention relates to a method for preparing organic calcium, in particular to a new method for preparing highly water-soluble organic calcium by using acidic fruit juice and eggshells. Background technique [0002] Calcium is an indispensable mineral element for the human body, accounting for about 1.5-2.0% of the body weight, and plays an extremely important role in the growth and development of the human body. The human body cannot synthesize minerals by itself, and is completely dependent on external supplements and supplies. Calcium deficiency seriously affects human health. There are many kinds of calcium preparations on the market, but most of them are chemically synthesized single ingredients, which are not only expensive, but also have some disadvantages to varying degrees, such as poor water solubility, low calcium content, irritation to the stomach, and side effects when taken for a long time Wait. The use of non-toxic and harmless natu...
