OK I know there are no dumb questions but gush darn I feel reel dumb on this one. As some know I'm venturing out into dry cure sausage and meat. I have been collecting some of the stuff I will need and a box arrived today. I ordered the pHydrion pH Strips to test for PH. They came in the box with all the other stuff I ordered. No instructions on how to use. Whats the best way to test the PH? So how do you use these? I know its simple but I want to get it right the first time. Oh and by the way I gots a box full of questions coming up so stick around ;D
Thanks
Don
Hydrion strips come in a variety of pH ranges. What are yours? You just dip them into the aqueous liquid in question and read against the scale on the package. If a sausage was damp on the surface I guess you could hold the strip against to get a pH reading. Just as point of interest a lower case p as in pH stands for the negative base 10 log of the upper case value. pH, pOH, pKa, etc. Here H is the molar hydrogen ion concentration.
I never got a good reading using the strips by laying them against the exposed surface of the sausage. Like you no instructions came with the strips. After searching the Wedlinydomowe site I finally discovered how to use them.
Here is the direct quote from their site:
"To use, mix 1 part finely chopped meat and 2 parts distilled water, tear off a strip of pH paper, dip into test solution, and match immediately to color chart. No technical training is necessary."

Usually there is a "short" sausage after stuffing. I use that as the one to take a plug of meat out of.
Thanks Habs
Dissolving in distilled water will give you a ballpark pH value but remember pH is concentration dependent. More dilution => higher pH value. Also, it is important that distilled water be used. Any mineral salts in the water can possibly act as a buffer and throw off the measurement.
Ditto with 3ren
Thanks guy for your input ......big learning curve for sure

That is true, and you clearly need to use distilled water. Even if you get a false reading because the pH is raised by the small amount of water; if you get a reading of 5.2 or lower you know the sausage is in a safe pH range. For my use I have gotten more accurate readings using Marianaski's method, then by rubbing the test strip against the meat. One of these days I am going to splurge and purchase a probe pH meter.

Me too. Need another
toy oops, I mean analytical instrument.
