Description

Food additive containing cacao bean or husk fraction extract

The present invention relates to an anti-inflammatory food additive containing cacao beans or bean skin fractions, and more particularly, is caused by digestive system inflammatory diseases and various dermatitis-causing substances caused by endotoxins secreted by bacteria. By identifying excellent inhibitory efficacy against primary contact dermatitis, it relates to an anti-inflammatory food additive containing cacao beans or soybean skin fractions.

Cacao, the raw material of chocolate and cocoa, has the scientific name Theobroma cacao L, meaning divine food. The origin of cacao is estimated to be from Central America to the northern part of South America, and has been cultivated for a long time in BC and has been treated with corn as a very valuable food. It is settled as a typical sign food. Cacao beans, which are used as raw materials for chocolate, vary depending on the country of origin, but are not only rich in dietary fiber, but also contain significant amounts of polyphenols.

On the other hand, cacao beans are shelled out during the production of chocolate so that nibs are used as raw materials for chocolate or cocoa, and shells (about 15% by weight of the total cacao beans) that are produced as by-products are almost discarded. In other words, the world produces about 2.5 million tons of cacao beans, about 400,000 tons of cacao beans are being discarded, and according to the 1990 Customs Statistics Korea, about 600 tons of cacao beans It is known that it is being discharged as waste. However, like cacao beans, such cacao beans are not only rich in dietary fiber, but also contain a significant amount of polyphenols.

Thus, methods have been devised to exploit the functionality of polyphenols in cacao beans. Polyphenols of various structures have been shown to inhibit the activity of leukemia, prostate cancer, colon cancer, kidney cancer, lung cancer, breast cancer and also inhibit topoisomerase II. It has been claimed to have a patent for the structure and use of these polyphenols (Korean Patent Application No. 1998-707952).

However, the inventors of the present invention are inexpensive since they use soybean peel polyphenol extracts obtained as by-products during chocolate production, long before the patents on the structure and the physiological activity of the polyphenols of cacao beans, which are claimed above, are filed. In addition, polyphenols are mainly composed of polymers such as procyanidin A and procyanidin C-1, and thus have high enzymatic inhibitory activity, which inhibits the activity of glucosyltransferase, a decay-causing enzyme. In fact, the cacao bean husk extract was prepared, and chewing gum containing the same was prepared [Korean Patent No. 45179, 1991; U.S. Patent 4908212, 1990. Recently, patents have been developed by increasing the content of polyphenols to prepare cacao bean husk fractions which further enhance the inhibitory activity of glucosyltransferases (US Pat. No. 6159451, 2000).

As mentioned above, cacao beans and bean husks contain various physiological activities such as dietary fiber, polyphenols of various structures, and phenolic acid, methylxanthines such as deobromine and caffeine. As a result, the specific structures of the polyphenols do not actually exhibit physiological activity, and the separation and commercial use of only these specific structures may be too expensive to use. Therefore, it would be practical to use fractions that greatly enhanced several physiological activities by a simple separation process as already registered in the patent (US Pat. No. 6,159,451, 2000).

Inflammation is a bacterium-derived abscess that actively infiltrate tissues with purulent fungi that white blood cells devour, resulting in the death of white blood cells, tissues damaged by bacteria, and cell debris, which accumulate in the tissues. It refers to the pathological condition of the place, and the anti-inflammatory effect is to inhibit the growth of invading bacteria by antibacterial agents, or to activate the macrophage that phages foreign matter accumulated in the abscess, thereby enhancing the ability to digest and excrete them. Abscess is the process of treatment. In general, an inflammatory response is a defense process of a living body that attempts to repair and repair the damaged area when an invasion that causes some organic change in a cell or tissue of the living body is applied. Therefore, such a series of reactions include local blood vessels, various tissue cells of body fluids, immune-involved cells, and the like.

To date, anti-inflammatory agents have been shown to inhibit the biosynthesis of prostaglandins activated by physicochemical and physiological stimuli from the cell membranes of damaged tissues or leukocytes inoculated by chemotactic factors in acute inflammation. (Moyazawa, K and Mikami, T., Japan J. Pharmacol., 38, 199, 1985). However, these drugs have a therapeutic effect on the symptoms of acute inflammation, but in chronic inflammation such as rheumatoid arthritis, only the primary inflammation is reported, and immunological therapeutic effects are not expected. Recently, researches on arachidonic acid have been actively conducted on hydroxyeicosatetraenoic acid (HETE), leukotriene B4, and leukotriene C4, which are substances produced by lipoxygenase. This has been shown to have some effect on chronic inflammation (Huskisson, ED et al., Inflammation, Mechanism and Treatment, MTP, Lancaster, England, p.55, 1980).

Therefore, it is necessary to study the substances that can be safely ingested without additional purification process, including natural plant extracts, can inhibit inflammation, and can be easily used in food.

However, there are no reports on the inhibitory effect of cacao beans and cacao bean husk extracts on inflammation caused by bacterial endotoxins and inflammation-causing substances.

Therefore, the inventors of the present invention, while studying the physiological activity of the cacao beans or soybean shell fractions from various angles, and revealed that these fractions have excellent inhibitory effects against digestive system inflammatory diseases and primary contact dermatitis caused by bacterial endotoxin in animal experiments. Thus, the present invention has been completed.

Accordingly, an object of the present invention is to provide an anti-inflammatory food additive containing cacao beans or a legume fraction.
