Confinements of composite materials including affinity of substances

Abstract

The present invention discloses collection confinements adapted for collection and preservation of edible substances during a minimal period of time required for conservation thereof, in particular aromatic edible substances, such as for example substances derived or associated with coffee or containing caffeine, whereby said confinements are produced in composite materials that provide barrier to the transfer of liquids and gases and present compositions that include synthetic polymers and/or bio-polymers, as well as further vegetal fibre associated with at least one sub-product from processing of the edible vegetal having affinity with the one being collected in said confinement, such as for example fibre of coffee silverscreen resulting from roasting of coffee beans, thereby providing a new economic utilization of such sub-products, and confinements presenting high bio-degradation degree once disposed thereof.
