Abstract

An object of the present invention is to provide a method for producing a tea aroma composition wherein the excellent aroma of tea leaves is enhanced.In the method for producing a tea aroma composition, tea leaves are treated by steam distillation to collect a distillate and then the obtained distillate is subjected to distillative concentration.

First claim

The invention claimed is:

1. A method for producing a tea aroma composition, the method comprising the steps of:
heating tea leaves at 30-80° C., wherein the tea leaves are soaked in water;
treating the heated tea leaves by steam distillation to collect a distillate; and
subjecting the obtained distillate to distillative concentration.

2. The method according to claim 1 , wherein the distillative concentration is atmospheric distillative concentration or vacuum distillative concentration.

3. The method according to claim 1 , wherein the distillative concentration step involves a salting-out treatment.
