Residual Quat Test Strips for Fermented Foods
SKU: 33819-100
Ensure safe probiotic-rich fermented foods with Indigo® residual QAC test strips; verify quaternary ammonium sanitizer residues at ≤100 ppm (detectable down to 10 ppm) to protect cultures, prevent off-flavors, and reduce allergy risks. Meet HACCP, FSMA, and export standards for dairy, soy, kombucha, pickled vegetables, and other fermented products.
Fermented foods such as yogurt, kefir, kimchi, sauerkraut, miso, and kombucha depend on carefully balanced microbial cultures that provide both flavor and probiotic health benefits. Sanitizing food-contact surfaces with quaternary ammonium compounds (QACs, or quats) helps prevent contamination and allergen cross-contact, but residual levels must remain ≤100 ppm to avoid harming beneficial probiotics or leaving unsafe residues. Indigo® residual quat test strips (0–100 ppm, sensitive down to 10 ppm) provide quick, reliable verification that sanitizer residues comply with HACCP, FSMA, and CFIA standards while preserving the probiotic viability that defines fermented foods.
All Indigo® Quat (QAC) test strips come in 100 (not 50) strips per pack & 3 year minimum guaranteed shelf life backed by a Certificate of Analysis, Stability & SDS documents as listed below; Certificate of Conformance on request. Be prepared for any health & safety audit or inspection.
