Appearance:Milky white powder About Tannase:
Tannase is a key enzyme in the degradation of gallotannins, a type of hydrolysable tannins. It is present in a diverse group of microorganisms, including rumen bacteria.
Tannase is an inducible enzyme produced by various Penicillium or Aspergillus in the presence of tannic acid. It can cut off the ester bond between catechol and gallic acid and release the gallic acid anion from tannic acid. Tannase is a tannin acylhydrolase which hydrolyzes acid having two phenolgroup such as tannic acid. The enzyme can be produced by molds such as Aspergillus niger and Aspergillus oryzae. It can be used to treat tannins and proteins in beer to make it clear and transparent. It can also be used to remove the astringency of persimmons and other products, as well as to make instant tea and prevent turbidity of fermented tea.
