Health-Beneficial Preparation and Production Method

A method for producing a nonlive Lactobacillus composition with specific binding ability for Streptococcus mutans, comprising the following steps:

• i) warming a suspension of cells of a Lactobacillus or a mixture of Lactobacilli with specific binding ability to Streptococcus mutans from a starting temperature of below 40° C. to a pasteurization temperature of 75 to 85° C. with a temperature change of 0.5 to 2° C./min, where the specific binding
• a) is resistant to heat treatment;
• b) is resistant to protease treatment;
• c) is calcium-dependent;
• d) takes place in a pH range of between 4.5 and 8.5;
• and/or
• e) takes place in the presence of saliva,
• ii) holding the warm suspension at the pasteurization temperature over a period of 20 to 40 min,
• iii) cooling the suspension held in step ii) to a final temperature of below 40° C., with a temperature change of 0.5 to 2° C./min.
