Can I use Tupperware™ to ferment my Kombucha Tea?
According to Günther Frank, Tupperware is a high-grade synthetic material of the polyolefine group, e.g., polyethylene (PE), or polypropylene. Wine or cider which has a pH value similar to that of Kombucha, is also stored in containers of this food-grade material. However, you should avoid containers made of polyvinyl chloride (PVC), or polystyrene. Sterol is damaging to one’s health and can pass from containers made of this material, into the liquid undergoing fermentation.
