Yota-Guard CWF (Cultured Wheat Flour) answers that challenge at the most natural point in the supply chain. It is a fermentation-derived, all-natural mould inhibitor produced by culturing wheat flour with food-grade Propionibacterium freudenreichii — the same beneficial bacterium behind Swiss cheese. The result is an off-white powder rich in naturally occurring propionic, acetic and lactic acids that extends mould-free shelf life while replacing synthetic preservatives.
