1. A single-use capsule configured for preparing in a beverage production device a food liquid from a food substance contained in the capsule by introducing water in the capsule and passing water through the substance using centrifugal forces for producing the food liquid which is centrifuged peripherally in the capsule relatively to a central axis of the capsule corresponding to an axis of rotation during centrifugation by the device, the capsule comprising:

  • an upper wall comprising a top membrane and an internal rigid lid, with the internal lid comprising or forming at least part of a continuous annular collecting recess, with the collecting recess being closed by the top membrane to form a first annular peripheral outlet region in which the top membrane is perforable and dedicated for providing outlets for the release of the liquid with the internal lid comprising a central opening closed by the top membrane to form a second region which is a central region dedicated for being pierced by a water injector of a liquid food preparation device, and with the upper wall comprising the internal lid placed below the top membrane to reinforce the top membrane between the first and second region so that the upper wall is non-perforable between the first and second regions;

    a lower wall; and

    a widening side wall connecting the upper and lower walls,wherein the lower wall, side wall and the internal lid define an enclosure having a rim onto which the top membrane is mounted and the enclosure contains a predetermined amount of food substance.
