Folks, I heed your help, please.
We are fruit and vegetable processing place and we are about to launch a new product which is peeled potatoes. It will come in both 5-gallon and 20-gallon containers filled with Sodium Metabisulfite solution to preserve the potatoes. I have instructions on mixing the right concentration. I don't feel comfortable going just by mixing formula. I need test strips or test kit to measure the concentration level. I don't even know what are safe levels for Sudium Metabisulfite for peeled potatoes. Please, if someone has expertise in that field, advise me on what I should do.
