Integrated milk pH indicator

Acidification is one of the main reasons why people throw milk away. To assess the acidity, a pH indicator is placed inside the lid and protected by a thin plastic film. The user removes the film and pours a little milk into the lid. Depending on the colour of the indicator, he can tell whether the milk can still be used or has already gone off.
