Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to health foods, and more particularly to health foods containing calcium as a main component.

[0002]

2. Description of the Related Art As a serious problem in an aging society,
An increase in the so-called "bedless elderly" can be cited. The cause is attributed to osteoporosis due to insufficient calcium intake, and fractures and the like tend to occur frequently due to insufficient calcium intake even in young people due to changes in dietary habits. Therefore, various tablets having bones, egg shells or shells as main components are commercially available as one of the health foods.

On the other hand, in recent years, single-cell algae (microalgae) such as chlorella and Dunaliella have been used as health foods. This is because microalgae are a type of plant and the whole algae can be used for food, which is suitable for healthy or natural diet.

[0004]

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention The above-mentioned tablet-like calcium health food is generally for supplementing mainly calcium and secondarily other mineral components.
On the other hand, health foods mainly composed of unicellular algae are rich in proteins and vitamins, but poor in other nutritional components. Therefore, an object of the present invention is to provide a health food capable of simultaneously ingesting various mineral components including calcium and various nutritional components.

[0005]

[Means and Actions for Solving the Problems and Achieving the Purpose] The inventors of the present invention have made various studies to solve the above problems and achieve the objects, and as a result, it is preferable to turn single-cell lime alga into food. I came to judge that there is. In other words, single-celled lime algae have the property of fixing calcium around cells as if they are armor, and proteins, lipids (especially highly unsaturated fatty acids such as EPA and DHA), carbohydrates, and vitamins And minerals other than calcium. Therefore, in making algae bodies of single-cell lime algae into food, the method of culturing the algae, the method of facilitating absorption of calcium components, the method of processing without losing nutrient components such as polyunsaturated fatty acids, and the storage stability are described. The present inventors have conducted intensive studies on methods for improving the properties, and thus succeeded in converting single-cell lime algae into food, thereby completing the present invention.

The health food according to the present invention contains algal cells of unicellular lime algae and contains calcium as a main component.
The health food according to the present invention can be in the form of tablets, in which case algae of unicellular lime algae, a granulating agent,
It contains a lubricant and an antioxidant. Further, the health food according to the present invention may be in the form of a capsule, and in this case, it contains algae of unicellular lime algae, an antioxidant, and a nutrient-enriched vegetable oil.

[0007] The unicellular calcareous algae used for producing the health food according to the present invention include Pleu lysis ( Pleu
rochrysis ), Gephyrocapsa ,
Algae of the genus Emiliania and the like, which are called coccoid algae or haptophytes, are preferable. Lactose is preferred as a granulating agent, talc as a lubricant,
Saccharose fatty acid esters and the like can be exemplified, but the latter is preferred, and the binder is preferably a saccharide, particularly reduced maltose, and the antioxidant is preferably vitamin C or E. Lactose and vitamin C also have the effect of promoting calcium absorption.

[0008] Fortifying substances include vitamin E, lecithin, brewer's yeast (containing a precursor of vitamin D), chlorella alga body (rich in protein), fermented rice germ extract [like superoxide dismutase (SOD) Containing a substance], and these substances can also be blended in the case of a tablet food.

[0009] The unicellular calcareous algae is basically a member of plants, and absorbs carbon dioxide to perform photosynthesis to generate its own energy. 0.03% carbon dioxide in the air
Therefore, it is important to enrich carbon dioxide to promote growth when artificially cultivating single-cell lime algae. In this case, air containing 1-5% carbon dioxide is supplied, or 100% carbon dioxide gas is introduced. However, an industrial exhaust gas, for example, a carbon dioxide-containing exhaust gas generated in large quantities by combustion in thermal power generation or the like can be cooled and used as the carbon dioxide source, thereby preventing pollution.

The alga body-containing culture solution is concentrated, for example, acetic acid is added to make it weakly acidic, and cyclodextrin and chitosan are added. This cyclodextrin is for inclusion of calcium and polysaccharides fixed on the cell surface of algae, various types, namely α-, β-,
γ-, δ-, ε- and polymer cyclodextrins or cyclodextrin sugars (candy powder) can be used, while chitosan is used to remove algal floc and microbial contamination. Is done.
In the case of a tablet food, a substance that promotes the absorption of calcium, such as lactose, can be added as a granulating agent.However, in the case of a capsule food, the amount to be enclosed is limited. It is preferable to add lactic acid to make the form of calcium lactate having good absorbability as close as possible. The obtained alga body-containing liquid is vacuum- or freeze-dried to powder.
The dry powder is used as a main raw material to be processed into a tablet or capsule food.
