Tannase Raw Materials Tannase Powder
Product Overview:
Tannase is a glycoprotein with molecular weight and glycan chain content varying depending on the source, consisting of 2-8 monomers polymerized with a glycan base content ranging from 12% to 62%. Different sources of tannase have different optimum temperatures and pH values, and are thermally stable in the range of 60-70°C or less. The effect of metal ions on tannase activity also varies.
Purified recombinant tea tree tannase rCsTanA is slightly less efficient at catalyzing natural substrates (EGCG) than synthetic substrates (EG and PG).
The tannase gene family is prevalent in tannin-rich plants such as persimmons, grapes, and strawberries, and is involved in the metabolism of the astringent compounds ester catechin, gallotannin, and ellagitannin

Tannase Raw Materials Tannase Powder Details
Tannase Powder Usage and Synthesis.
Tannase is a glycoprotein that varies in molecular weight and sugar chain content from different sources. Tannases convert tannin compounds to butyric acid during starch saccharification, thereby reducing the astringency of the raw material.
In addition, tannase plays an important role in the alcoholic fermentation process by saccharifying starch into fermentable sugars, which provide nutrients for the growth and fermentation of microorganisms such as yeast. The optimum temperature and pH of tannase varies depending on the source, generally between 30-40°C, with a heat-stable range of 60-70°C or less.
Uses of Tannase.
Enzyme preparation. Mainly used in the production of instant tea to break down the tannin, in order to improve the cold solubility of the finished product and to avoid hot soluble in the cooling turbidity. When used in the pH value of 5.5 ~ 6 of the tea extract, according to the ratio of 2.5g per liter of ellagitannase preparation, and then stirred at 30 ℃ for 70min, and then warmed to 90 ℃ to inactivate the enzyme, centrifugation to remove the tannase, can be.
Tannase is an extracellular enzyme produced from Aspergillus niger. The enzyme acts as a lipase, decomposing tannins into ellagic acid. It can be used to remove tannins in the fruit juice, tea beverage and beer industries.
Physiological effect of Bulk Tannase Powder.
Product Methods of Tannase.
It is generally produced by controlled cultivation of Aspergillus niger (Aspergillusniger) or Penicilliumglaucum (Penicilliumglaucum) in Chua's medium (CzapekDox) containing 2% ellagic acid and 0.2% casein hydrolysate, removal of the mycelium, and drying after precipitation with acetone.
