Good day Everyone,
I have a question regarding the sanitation validation against starch residues.
We are developing a powder handling equipment. One of its use is to deliver anti-caking agents. I tried to validate the easiness to clean using 3M ATP swabs. However, this method doesn't seem to be very sensitive to the starch residue. I get very low readings like 11 RLU while the residue is clearly visible. I guess it's because starch doesn't have too much ATP in it?
I was wondering if there is a commonly used way to detect starch residue, like in a bread plant? Or you have any good ideas that can help? Please let me know.
Thanks in advance.
