PROBLEM TO BE SOLVED: To provide a method for producing new fermented soybean which can be readily taken on a daily basis, and enables even a person who is weak in and/or has allergy to dairy products to take lactobacillus having disease germ-inhibiting activity on a daily basis, in view of the fact that the person who is weak in and/or has allergy to dairy products can not take yoghurt on a daily basis while the yoghurt, containing lactobacillus having function to inhibit disease germs such as Helicobacter pylori involved in development of gastric/duodenal ulcer, is generally used as health food: and to provide a method for preparing the new fermented soybean and/or food and drink thereof.SOLUTION: The new fermented soybean includes genus Lactobacillus lactic acid bacterium inhibiting disease germs such as Helicobacter pylori and bacillus natto. In production of the new fermented soybean and the food and drink thereof, the fermented soybean and the food and drink thereof contain lactic acid bacteria belonging to the group of Lactobacillus acidophilus not spoiling characteristics of fermented soybean, such as stringiness, flavor and taste inherent in the fermented soybean.COPYRIGHT: (C)2012,JPO&INPIT【課題】胃・十二指腸潰瘍の発症に関与するヘリコバクター・ピロリやその他の病原菌を抑制する作用がある乳酸菌を含有するヨーグルトが健康食品として汎用されているが、乳製品の苦手な人やアレルギーのある人は日常的にヨーグルトを摂ることができない。日常的に手軽に飲食でき、乳製品の苦手な人やアレルギーのある人にも病原菌の抑制活性をもつ乳酸菌を日常的に摂取させることができる新規な納豆の作製方法及び/又はその飲食品を提供する。【解決手段】ヘリコバクター・ピロリその他の病原菌を抑制するラクトバシラス(Lactobacillus)属乳酸菌と納豆菌を含有する新規の納豆及びその飲食品の製造において、納豆としての糸引き、風味、味等納豆の特性を損なわないラクトバシラス・アシドフィルス(Lactobacillus acidophilus)グループの乳酸菌を含有する納豆及びその飲食品。【選択図】なし
