- a decomposing enzyme can reduce the astringency in the raw material and increase the umami and sweetness.
- Another feature of the present invention is that it has been confirmed that turbidity and sedimentation can be suppressed in beverage tea itself produced based on the tea product produced by the above production method, but this is also a second step.
- This effect is due to the action of the added degrading enzyme.Beverage produced by this effect can prevent turbidity and precipitate formation due to long-term storage and cooling, resulting in a clear beverage with no change in appearance.
- the present invention even for green tea raw materials, oolong tea raw materials, and black tea raw materials, by adding a step of adding a decomposing enzyme, the astringency in the raw materials can be suppressed, and the umami and sweetness can be increased. It is now possible to control the quality constantly by changing the raw material composition.
