Antibacterial composition

Abstract

It is intended to prevent contamination with the use of a food. As a candidate food, attention is given to an acidic fluid food which comprises an antibacterial fluid food having been acidified by adding a fermented milk product as a protein source. The antibacterial function of the acidic fluid food is compared with the antibacterial functions of the fermented milk product employed as the starting material and a neutral fluid food. Although it has been already known that fermented milk such as yogurt has an antibacterial function, the above-described acidic fluid food unexpectedly shows a stronger antibacterial function than the fermented milk product employed as the starting material on gram-positive bacteria such as MRSA which are important from the viewpoint of public health.

Description

technical field

[0001] The present invention relates to compositions having antimicrobial activity. Background technique

[0002] Liquid diets are widely used in hospitals, nursing homes, etc., and are used for those who have difficulty in taking in oral nutrition or have swallowing disorders. Liquid diets are injected into the body through catheters and tubes inserted through the nasal cavity, PEG (percutaneous endoscopic gastrostomy), etc., but generally, the users of liquid diets are the elderly or patients with certain diseases. Low immunity, easy to be infected with pathogenic bacteria.

[0003] In such institutions where there are many susceptible persons, once infection occurs, it may develop into nosocomial infection or institutional infection through medical staff and the like. Although the awareness of measures to prevent nosocomial infection has increased, there are more and more problems of nosocomial infection due to the increase of elderly people and the emer...
