COMPOSITION CONTAINING LEVAN FOR PROMOTING GROWTH OF INTESTINAL LACTIC ACID-PRODUCING BACTERIA

摘要

PURPOSE: A composition containing levan as natural polysaccharides for simulating the growth of intestinal lactic acid-producing bacteria containing bifidus bacteria in the intestine by mixing microorganism-derived levan in powder or aqueous state with lactic acid bacteria. The composition remarkably increases the number of lactic acid in the intestine while reducing the pH of the lactic acid. CONSTITUTION: The composition for stimulating the growth of intestinal lactic acid-producing bacteria contains levan alone or a combination with lactic acid bacteria in a ratio of lactic acid bacteria to levan of 1:2 to 1:10. The composition contains 0.1 to 10% by weight of levan on a solid basis or 0.1 to 7% by weight of levan on a liquid basis. It prevents death of lactic acid bacteria with low acid resistance within the stomach to cause lactic acid bacteria in large quantities to reach the intestine and thus can be effectively used in health food and medicine.
