The present invention relates to a method for mixing lactic acid bacteria and kelp powder or a kelp extract with high stickiness in order to allow lactic acid bacteria to easily adhere to human intestines. Lactic acid bacteria powder is generally capsulated and taken with water, but the water flows away. Accordingly, even though water is mixed with lactic acid bacteria, the lactic acid bacteria are washed away and thus cannot easily adhere to human intestines. Therefore, the method enhances the stickiness of lactic acid bacteria by mixing the lactic acid bacteria and kelp powder or a kelp extract with high stickiness, and thus allows the lactic acid bacteria to easily adhere to human intestines. People can have further strong intestines, and harmful bacteria are prevented from adhering to human intestines. Lactic acid bacteria-containing powder includes alginic acid in a content which is equal to or greater than 20% and less than 100%.COPYRIGHT KIPO 2016본 발명은 유산균이 장에 잘 유착되도록 강한 점성을 가진 다시마 가루나 다시마 추출물질을 섞는 방법에 대한 것이다.유산균 분말은 캡슐화하여 물과 함께 섭취하는 경우가 많은데 물은 흘러내려가 버리기 때문에 유산균과 같이 섞이더라도 흘러가 버려 잘 정착하지 못할 수 있다.이에 강한 점성을 가진 다시마 가루나 다시마 추출물질을 섞어 점성을 높여 장에 잘 유착되도록 할 수 있다.장이 더 튼튼해 질 수 있고 유해균이 장에 정착하는 것을 막는다.
