Publication description

This report compiles the results of an international collaborative study conducted to establish precision figures for the determination of acidification activity of dairy cultures by continuous pH measurement with the method described in ISO 26323|IDF 213. The cultures used were: mesophilic O-starter culture of Lactococcus lactis strains, mesophilic LD-starter culture of Lactococcus lactis, Leuconostoc mesenteriodes and Lactococcus lactis subsp. Lactis (biovar.) diacetylactis strains and thermophilic starter culture of Streptococcus thermophilus strains.

The summary of the collaborative study is included in the report and into the International Standard.
