Patent of the Day: Tea leaves that infuse in cold water!

I was looking for water infusion tactics and stumbled upon this, a patent for a tea leaf that infuses in hot and cold water…

“Green tea leaves are macerated, treated with tannase, fermented in the presence of hydrogen peroxide in an amount that is sufficient to activate endogenous peroxidases to oxidise gallic acid and other compounds that are liberated by the tannase treat

The patent is owned by Unilever, the largest consumer products company in the world.
