Disclosed is a method for manufacturing aromatised plant material, such as leaf tea. The method comprises: providing an homogenous mass of plant material; arranging the mass of plant material to extend from a first point (P1) to a second point (P2) distal from the first point, there being a gas-permeable path (P) connecting the first and second points; providing the plant material at the first point (P1) with an aroma composition comprising at least one aroma compound in an amount to form a concentration gradient of the at least one aroma compound along the gas permeable path (P); allowing the concentration gradient to evolve for a migration time (t); and dividing the mass along the path (P) into a plurality of fractions of aromatised plant material (1, 2, 3, 4), wherein at least two of the fractions differ in the concentration of the at least one aroma compound.
本发明公开了一种制造芳香化植物材料(如叶茶)的方法。该方法包括提供均匀的大量植物材料;将大量植物材料从第一点(P1)布置到离第一点较远的第二点(P2),存在连接第一点和第二点的气体渗透路径(P);在第一点(P1)处向植物材料提供包含至少一种芳香化合物的芳香组合物,其用量足以沿气体渗透路径(P)形成至少一种芳香化合物的浓度梯度;允许浓度梯度在迁移时间(t)内演化;以及 将沿路径(P)的质量分成多个芳香化植物材料馏分(1、2、3、4),其中至少两个馏分的至少一种芳香化合物的浓度不同。
