Problems solved by technology

In recent years, calcium supplementation preparations have developed rapidly, such as calcium carbonate, which contains relatively high calcium content, and because of its safety, effectiveness, and especially cheap advantages, it is the most widely used in this type of calcium preparations, but calcium carbonate is alkaline , and the solubility is low, it must react with a large amount of gastric acid in the stomach to generate ionized calcium before it can be absorbed
Calcium oxide, for example, has high calcium content and the best water solubility. It was once used for calcium supplementation in emergency situations, but it has been basically eliminated due to relatively serious side effects such as acute toxicity.

Embodiment 1

[0042] The production method of highly absorbing nano-calcium comprises the following steps:

[0043] Step 1. Wash the eggshells with water, lye, and water in turn, and then bake them at 55°C, 90°C, 170°C, 90°C, and 45°C for 3 minutes, 8 minutes, 8 minutes, 3 minutes, and 3 minutes respectively, and then bake them at 55°C, 90°C, 170°C, 90°C, and 45°C. During the drying process at this temperature, spray the organic acid on the surface of the eggshell every 20s, then crush the baked eggshell to obtain eggshell powder, add an organic acid of 1 times the quality of the eggshell powder to the eggshell powder, and Soak at 20°C, 38°C, 60°C, 80°C, and 38°C for 2h, 4h, 18h, 15h, and 4h respectively, then filter and collect the calcium acid solution;

[0050] The production method of highly absorbing nano-calcium comprises the following steps:

[0051] Step 1. Wash the eggshells with water, lye, and water in turn, and then bake them at 60°C, 100°C, 180°C, 100°C, and 50°C for 5 minutes, 10 minutes, 10 minutes, 5 minutes, and 5 minutes respectively, and then bake them for 5 minutes. During the drying process at this temperature, spray the organic acid on the surface of the eggshell every 30s, then pulverize the baked eggshell to obtain eggshell powder, add an organic acid twice the quality of the eggshell powder to the eggshell powder, and Soak at 25°C, 42°C, 65°C, 90°C, and 42°C for 3h, 5h, 20h, 18h, and 5h respectively, then filter and collect the calcium acid solution;

Abstract

The invention discloses a production method of high-absorption nano-calcium. The method comprises the following steps of: step 1, cleaning eggshells with water, alkali liquor and water in sequence, then respectively baking at 55 to 60 DEG C, 90 to 100 DEG C, 170 to 180 DEG C, 90 to 100 DEG C and 45 to 50 DEG C in sequence; spraying organic acid onto the surfaces of the eggshells every other 20-30s in the drying process of the five temperatures, then smashing the baked eggshells to obtain eggshell powder, adding the organic acid for soaking, then filtering, and collecting a calcium-containingacid solution; and 2, adding absolute ethyl alcohol into the calcium-containing acid solution, stirring, centrifuging, taking the solid, washing the solid with absolute ethyl alcohol, and carrying outfreeze drying to obtain the nano-calcium. The preparation method has the beneficial effects that the preparation process is simple, and the prepared nano-calcium is small in particle size, high in solubility and easy to absorb. The invention provides nano-calcium and a food containing the nano-calcium. The invention further provides application of the nano-calcium in preparation of a product forincreasing bone mineral density.

Description

technical field [0001] The invention relates to the field of eggshell deep processing. More specifically, the present invention relates to a production method of high-absorption nano-calcium and its products and applications. Background technique [0002] The egg shell accounts for 10-12% of the weight of the whole egg. It is composed of three parts: the upper membrane, the lower membrane and the eggshell. The eggshell is a calcareous hard shell, located between the upper membrane and the lower membrane. There are a large number of absorption pores on the surface of the eggshell, each eggshell has about 10,000 pores, which is conducive to the formation of fine, powdery powder. In the chemical composition of eggshells, minerals account for 95%, protein 3.3%, water 1%, fat 0.03%, and the rest are carbohydrates and other organic substances. The mineral components of eggshells are mainly calcium carbonate, accounting for about 94%, and the rest are magnesium carbonate and calc...
