Patent ID: 8921060

Claim:
A method for preparing a composition comprising nonlive Lactobacillus 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.
