Abstract

The tentative method proposed by the Public Health Laboratory Service of the Ministry of Health for grading ice cream according to hygienic quality by applying a methylene blue test has been given an extended trial. The test is considered unreliable because thermoduric organisms alone have been found to reduce methylene blue under the conditions of the test in presence of certain ingredients, such as milk powder, used in ice cream.
