Definitions

  • the present disclosure relates generally to nutritional compositions and, more particularly, to systems and methods for rendering a nutritional composition housed in a container suitable for consumption, as well as to such containers.
  • WO 2006/015689 discloses reconstituting consumable powders with a liquid to provide a food liquid such as milk, cappuccino-type beverage, or soup.
  • the consumable powder is introduced into a container and pre-wetted by introducing a wetting liquid stream into the container such that the wetting liquid stream intersects in mid-air with the powder as the powder is being introduced into the container.
  • the pre-wetted powder is then mixed to form the food liquid by introducing a mixing liquid stream into the container.
  • the general inventive concepts are based, at least in part, on the discovery that pre-treating a nutritional composition (e.g., a powder or concentrated liquid composition) stored in a sealed container, capsule, or the like (generally, a "pod") with a pre-treating fluid deposited into the container, prior to mixing the pre -treated composition with a reconstituting fluid, may promote improved processing of the nutritional composition into a reconstituted nutritional liquid formulation.
  • This improved processing may include, for example, faster dissolution of a powder nutritional composition, more homogenous mixing of the composition, reduced contamination of a processing device used to process the nutritional liquid formulation, more efficient preparation of the nutritional liquid at an acceptable temperature, and reduced preparation time.
  • this improved processing efficiency can result, for example, in improved dissolution of the powder nutritional composition in a reconstituting liquid (e.g., water), a shorter period of time until acceptable dissolution of the powder nutritional composition occurs, and/or a shorter period of time until an acceptable output characteristic (e.g., temperature) is achieved.

Abstract

Dans un procédé donné à titre d'exemple permettant de reconstituer une poudre nutritionnelle dans un liquide nutritionnel, l'invention porte sur un récipient doté d'une chambre fermée hermétiquement retenant une quantité prédéfinie de la poudre nutritionnelle. Au moins une ouverture d'admission (32) est produite dans le récipient, ladite ouverture d'admission étant en communication fluidique avec la chambre. Un premier volume de fluide de pré-traitement est introduit à travers ladite ouverture d'admission dans la chambre pour pré-traiter la poudre nutritionnelle. Une ouverture de sortie (34) est produite dans le récipient, l'ouverture de sortie étant en communication fluidique avec la chambre. Un second volume de fluide reconstituant est introduit à travers ladite ouverture d'admission dans la chambre, et le fluide de pré-traitement, le fluide reconstituant, et la poudre nutritionnelle forment le liquide nutritionnel. Le liquide nutritif est expulsé à travers l'ouverture de sortie.
