Abstract

The invention relates to a novel method of evaluating the breath of a test subject. A breath sample from a test subject is collected in a container. The microbial load of the breath sample collected in the container is reduced. The breath sample collected in the container is evaluated by a tester.

Claims

1. A method of evaluating the breath of a test subject, comprising the following steps:

a) collection of a breath sample from the test subject in a container,

b) reduction of the microbial load of the breath sample contained in the container, and then

c) evaluation by a tester of the breath sample collected in the container.

2. A method according to claim 1, characterized in that, in step a), the container is filled with breath by the test subject against atmospheric pressure by exhalation.

3. A method according to claim 1 characterized in that the volume of the container is variable, the container preferably being collapsible.

4. A method according to claim 1 characterized in that the container possesses an internal surface made of an odourless material.

5. A method according to claim 1 characterized in that the container is filled with 20 ml to 7 1 of breath in step a).

6. A method according to claim 1 characterized in that the microbial load is reduced by condensation of moisture from the breath sample in the container.

7. A method according to claim 1 characterized in that the temperature of the breath sample is adjusted to a value of 20°

C. to 40°

C. before performing step c).

8. A method according to claim 1 characterized in that the test subject fills the container in step a) by exhaling through the mouth, and preferably after inhaling through the nose.

9. A method according to claim 1 characterized in that the breath sample is anonymised prior to evaluation.

10. A method of evaluating an oral care product, comprising the following steps:

a) taking a first breath sample from a test subject by a method according to claim 1,

b) subsequently administering the oral care product to the test subject,

c) taking an additional breath sample from the test subject using a method according to claim 1 at a pre-selected time after administering the oral care product, and

d) comparing the first and the additional breath samples by a tester.
