Description

FIELD OF THE INVENTION

The present invention refers to the field of edible components in edible products, in particular to the field of edible components including compounds that can be extracted from coffee, and to corresponding systems of edible products and uses thereof, in particular to the field of preparation of beverages, such as for example coffee based aromatic beverages and other beverages, that present edible components.

BACKGROUND OF THE INVENTION

The prior art presents several solutions of edible products presenting edible components of different composition.

Coffee is an edible products that presents a significant number and diversity of organoleptic properties resulting from a particularly complex matrix of multiple chemical substances that are present to a smaller or greater degree according to different factors, such as for example the blend, type of processing and other. Some of these chemical substances present valuable benefits in different types of applications such as the case of the classes of compounds to be used in the synthesis of edible coatings.

Moreover, coffee is an edible products that can be provided in different forms, including roasted ground coffee, available in the form of loose granulate and of compacted pod and used for example in the preparation of espresso type coffee, soluble coffee in the form of soluble granulate, coffee concentrate in the liquid form, and other.

In general, the systems of distribution of coffee require packages, such as for example rigid capsules or flexible pods of single portions, that provide an effective water, humidity and oxygen barrier, so as to ensure the protection/maintenance of proprieties, aromas and tastes associated with several of said chemical substances, in particular volatile compounds. However, the use of standard package materials, such as for example synthetic materials and aluminium, is associated with multiple economic, environmental costs and, even, quality constrains of the edible product. There is therefore a possibility of creating new systems of edible primary packaging.

Moreover, there are several properties associated with several compounds present in coffee and that provide a better behaviour of certain coffee derivate, such as for example better crème formation in espresso type coffee or better aromatic profile in soluble type coffee. There is therefore a possibility of improving several properties of edible products, such as for example coffee-based aromatic beverages, by means of adding an edible component that presents an appropriate content of such compounds extractable from coffee.

Moreover, there is growing evidence that certain compounds that are present in coffee provide beneficial health effects, whereby said compounds are present in different fractions according to the type of coffee blend or derivate thereof.

Documents WO 2011/123949 and WO 2013/049928 A1 disclose edible coatings for preserving an organoleptic propriety of a food product and that includes a polysaccharide, in particular a polysaccharide selected from the group that comprises carrageenates, gelane, sodium alginate and pectin, and a solution of reticulating agent.

Document WO 2015/097335 A1 discloses an edible coating for the conservation of pieces of fruit and that includes a first polysaccharide aqueous solution and a second aqueous solution that includes a crossing of a calcium agent for the jellification of the polysaccharide in the first aqueous solution.

Document US 2008317931 A1 discloses a capsule for preparation of beverages including two compartments, whereby the wall of a compartment contains a water soluble material, in particular said wall contains a sucrose syrup, glucose syrup, other polysaccharides or mixtures thereof.

Document US 2010303969 A1 discloses dissoluble films impregnated with tobacco, tea, coffee, botanic and tastes for oral products. Said film comprises combining finely divided particles of vegetable material with a first coating material in a liquid medium, mixing a second coating material, inducing the formation of a gel matrix and forming a film from said gel matrix.

Document US 2013056551 A1 discloses an aroma encapsulated so that can be released, in particular gelatine capsules that encapsulate at least one aromatic compound. The gelatine capsules comprise complex coacervate agents formed by gelatine formed by gelatine and anionic hydrocoloid polymer.

The document “Galactomannans use in the development of edible films/coatings for food applications”, M. A. Cerqueira et al., Trends in Food Science & Technology 22 (2011) 662-671, does not disclose the use of certain coffee derivate, in particular of at least one polysaccharide extractable from coffee in the composition of an edible coating.

None of the documents in prior art discloses an edible component that provides an effective barrier for maintaining the main chemical properties associated with coffee, and that besides thereof, enhances certain chemical properties associated to coffee and derivate thereof.
