Duotest pH Test Strip

pH test strips are used for testing the acidity of your inoculated milk and/or preserves.

When making some cheeses such as Cultured Mozzarella and Provolone, the timing for adding the rennet is dependant on the acidity of the milk and culture mix in your pot.

Use as little as 1 cm at a time
Simply cut a small piece of the test strip, and touch to some inoculated milk in a spoon. The strip started "green & yellow" and very quickly changed to "dark pink & blue", indicating a pH of 6.8 or even higher.

Suitable tor testing pH from 3.5 to 6.8.

These testing strips are promoted as safe to use in jams, etc, but when you put them in food, the colour leaches out. The only safe way to use this product on food is to remove some of whatever you are testing into a separate jar and test that, then throw it out. Don't consume the product that had the testing strip inserted into it.
