Measuring the pH of bread dough

In the food industry, pH monitoring may be required during the production or pre-production process for a number of reasons including for microbe monitoring and taste purposes. In baking and bread-making there are a number of reasons why you would wish to know the pH - having a low pH in sourdough inhibits growth of pathogenic bacteria and in bread dough pH control agents (preservatives) may be...

The importance of testing pH in Dairy Products

Testing pH in milk and dairy products is key to detecting impurities and signs of infection both upon collection of milk at the point of delivery. In the sterilization process, checking the pH is important as the lower the pH the faster the process will be.  However, lower pH values in milk may also indicate that the cattle producing it may carry  an infection. pH Importance in the Cheese Manu...

What to do when your pH meter does not measure pH properly

[caption id="attachment_9145" align="alignright" width="150"] PH Meter[/caption] pH meters are wonderful devices until they go wrong. You are then left with your sample sitting on the bench and in some instances, not knowing what is wrong. The following questions and answers are designed to help you diagnose the problem. My pH meter won't give a fixed reading – is drifting or providing erratic...

What is sodium error or Na error in a pH electrode?

Q: I am looking to buy a pH electrode, many of them say "Na error over..." - what does this mean? A: Sodium error is also known as alkaline error, and is a phenomenon that occurs at very high pH levels - usually pH 12 or over. At very basic or alkaline pH levels, where Hydrogen ion concentration is relatively low compared to the Sodium ion concentration in the sample, you can see a Sodium...

What is the difference between a single junction and double junction pH electrode?

pH electrodes have many options to choose from;  tip shape, junction type, shaft material and fill solution. A key difference is whether the electrode has a single or double junction. How do electrodes work? Combination electrodes work by having a sensing half-cell (AgCl covered silver wire) and a reference half-cell (Ag/AgCl reference electrode wire), these two components must be joined ...

How do I store my pH electrode when not in use?

[caption id="attachment_112" align="alignleft" width="142"] Camlab pH Electrode Soaker storage bottle[/caption]   To prevent the glass pH membrane and junction from drying out it is recommended to store your electrode in an electrode storage solution. The best solution for this is 50% saturated KCl and 50% pH 4 buffer in conjunction with a soaker storage bottle. pH buffer is used bec...
