PURPOSE: To preserve tea leaves in good condition for a long time by a method wherein various kinds of tea leaves and cream powder are put in small water- permiable bags, the small bag is sealed in an outer bag made of a gas-barrier material, replaced with nitrogen gas, and then packed.
CONSTITUTION: Tea leaves selected from a group of black tea, green tea, powdery green tea and a mixture including more than two of them, and cream powder are put in a small water-permiable bag respectively. The small bags are sealed in an outer bag made of a gas-barrier material, replaced with nitrogen gas and then packed. In this instance, the small bag is made of sheet of paper or polypropylene, unwoven cloth or mixture of them. On the other hand, as the gas-barrier material of which the outer bag is made, a laminate film compound is used in which paper or synthetic resin film such as polypropylene is pasted on one or either side of aluminium film. Thus a package is obtained by which, if the tea leaves are preserved for a long time, flavor and taste of the tea leaves are not degraded.
