Description

Manufacturing method of dietary fiber from white ginseng

The present invention relates to a method for producing dietary fiber from white ginseng meal. More specifically, the method for producing dietary fiber is characterized by preparing white ginseng meal which has been mainly discarded or used as an animal feed until now, powdered, dispersed in water, and polished to prepare a paste. It is about.

White Ginseng (Panax Ginseng alba or Ginseng Radix alba) is dried and peeled from the roots and skins of the collected ginseng roots (Ginseng). Products manufactured from these white ginseng are ginseng extract, ginseng tea and ginseng extract granules. Food, medicine, cosmetics such as ginseng drink, ginseng soap and the like. The ginseng extract, which is used as a raw material of these ginseng products, is extracted from ginseng with ethanol or dilute ethanol. At this time, a large amount of ginseng foil is obtained as a by-product.

Dietary fiber is a non-digestible substance that is not decomposed by the digestive enzymes in the human body of vegetable food ingredients, and refers to a combination of poorly soluble cellulose, hemicellulose, lignin and soluble pectin, shells and mucus [Traowell, H. , (1985), Dietary fiber: a paradigm, Diatray Fiber, Fiber-Depleted Foods and Diseases, Trowell, H., Burkitt, D. and Heaton, K, (Eds), Academic press, Lodon, pp. 1-20], a combination of soluble pectin (shell, mucus) and poorly soluble fiber (NDF) is called dietary fiber [Vidal-Valverde, C., Frias, J. and Esteban, R., Dietary fiber in processed lentils, J. Food Sci., 57, 1161 (1992).

Soluble dietary fiber is known to have a positive effect on hyperlipidemia and arteriosclerosis in humans and animals, and pectin consumption is known to be related to the lowering of plasma cholesterol in both clinical and animal studies [Southgate, DAT, Waldrom]. , K., Johnson, IT, and Fenwick GR (Ed), 1990, Dietary Fiber: Chemical and Bio-logical Aspects, Royal Society Chemistry, Cambridge, Great Britain].

In modern society, the awareness of dietary fiber is renewed as the incidence of food-derived adult diseases increases due to the increase in meat intake and excessive intake of nutritious foods. This is because ingestion of an appropriate amount of dietary fiber may delay or control the absorption of nutrients, minerals, etc., thus reducing constipation by preventing adult diseases or by controlling intestinal exercise. [The nutritional significance of dietary fiber, Nutrition, 5, 14, (1993)].

Recently, as the interest in dietary fiber has increased in Korea, research on domestic vegetable dietary fiber has been conducted extensively and actively [Lee Kyung-sook et al., Analysis of dietary fiber content in Korean vegetable foods, Korean J. Food Sci. Technol., 25, 225 (1993): Hong, Sik et al., Preparation of dietary fiber source using apple pomace and soymilk residue, J. Korean Agric. Chem. Soc., 36, 73 (1993)] The dietary fiber of ginseng is known for its content, adjustment, and physicochemical properties of pectin [Min Kyung-chan et al., Studies on the nonstarchy polysaccharides of Korean ginseng, Panax ginseng CAMeyer, I. Content and compsition of dietary fiber, hemicellulose, cellulose, lignin and pectin, Korean J, Ginseng Sci., 8, 91 (1984); Min-Kyung et al., II, Physicochemical properties of pectic substances, Korean J, Ginseng Sci., 8, 105 (1984)]. A study on the improvement of die-tary protein-efficiency by supplement of the Panax ginseng by- using the stem and leaves of ginseng discarded as a by-product after cultivation and production of ginseng products, Korean J. Ginseng Sci., 3, 1 (1993). However, as in the present invention, there was no study on the method of producing dietary fiber of ginseng by processing white ginseng.

While the present inventors have been studying a method for utilizing white ginseng, which has been regarded as a by-product, which has been considered almost useless until now, the inventors thought that white ginseng could be used as a resource for soluble dietary fiber [Dreher, ML, 1987). , Handbook of Dietary Fiber, an Applied Approach, Marcel, Inc., New York and Basel, pp 53-114], and analyzed the content of pectin (PS) and poorly soluble fiber (NDF). The present invention was completed by confirming that it is very useful as a resource.

Hereinafter, the present invention will be described in more detail.
