I am first time writing here from Malaysia. I have been following most of the forums and I get lots of informations. Thanks to IFSQN.
My question is.... We are producing salad dressing and one of the ingredient is distilled white vinegar. We are currently storing the distilled white vinegar in a stainless steel tank. From what I observed, there is formation of slime in the tank after over 1 week of storage. When tested for microbes, there were high TPC and presence of coliform.
Then, we cleaned up the tank with sanitising cleaner and sprayed sanitiser before storing the second round of vinegar. Exactly a week later the slime formed again.
Can the vinegar be stored in stainless steel tank? Vinegar supposed to last longer than water or oil ( as we have oil and water tank too).
Please advice. Thank you.
