The high pressure extraction capsule (1) for the preparation of a single beverage acts as a barrier to the flowing fluid up to a certain pressure, above which it is possible to extract the fluid containing the active ingredient, but still of the particles Having a porous hydrophobic membrane (5, 10), which acts as a barrier to ground herbs or roots in particular, the pore size of the membrane (5, 10) being greater than 0.45 pm, the hydrophobic membrane (5, 10) is arranged and configured to have a surface tension of less than 40 dyn / cm. Preferably, the hydrophobic membrane (5, 10) has a surface tension of less than 40 dyn / cm, preferably about 30 dyn / cm, and a pore size in the range of 0.45 μm to 10 μm, preferably 0.45 μm to 5 μm. It is arranged to have. The capsule (1) comprises an inlet port (2), a compartment (3) for holding a substance having an active ingredient such as crushed herbs or roots, an outlet port (4), and a compartment (3). And a hydrophobic membrane (5, 10) for separating from the outlet port (4). The hydrophobic membrane (5, 10) can be supported by a nonwoven fabric or by the support means of the capsule (1). According to another embodiment of the invention, the capsule (1) comprises a first compartment (3) and a second compartment (8), the inlet port (2) being in the first compartment (3). The second compartment (8) communicates outwardly into the outlet port (4) and the first membrane (9) leads the second compartment (8) from the outlet port (4). The first compartment (3) is separated from the second compartment (8) using the second membrane (10), and the second membrane (10) has a higher resistance to resistance than the first membrane. Has water pressure.シングル飲料調製のための高圧抽出カプセル（１）は、ある圧力までは流れる流体に対する障壁として作用し、前記圧力を超えると、活性成分を含む流体を抽出することを可能にするが、依然として粒子の、特に粉砕された薬草または根に対する障壁として作用する、多孔質疎水性膜（５、１０）を有し、膜（５、１０）の孔径は０．４５ｐｍよりも大きく、疎水性膜（５、１０）は、４０ｄｙｎ／ｃｍ未満の表面張力を有するように配置構成される。好ましくは、疎水性膜（５、１０）は、４０ｄｙｎ／ｃｍ未満、好ましくは約３０ｄｙｎ／ｃｍの表面張力を有するように、かつ０．４５μｍから１０μｍ、好ましくは０．４５μｍから５μｍ
