Embodiment Construction

[0132] see figure 2 , the first detailed embodiment of the capsule of the present invention will now be described.

[0133] "Total solids" is defined as the weight of extracted solids contained in the extract divided by the total weight of the extract. This value is usually expressed as a percentage.

[0134] "Extraction yield" refers to the property of the extract and is defined as the weight of the total solids in the liquid extract divided by the total weight of the original coffee ingredients (eg, roast and ground coffee) in the cartridge. Usually this value is expressed as a percentage.

[0135] Average particle size "D 4，3 "Represents that by using Average volume diameter of coffee grinds obtained by laser diffraction with optical instruments and butanol as particle dispersant.

[0136] "Crema" is defined as the head of foam formed on the coffee extract with a rather small bubble texture. Crema properties can be measured by an empirical sugar test that includes a...

Abstract

A sealed capsule contains a beverage ingredient in powder form, in particular, ground coffee. The capsule comprises a base body (4) and a foil member (5) tightly attached to the base body (4), the foil member (5) being made from a material allowing the production of a multitude of perforations in the foil member (5) when the foil member (5) is thrust, via the pressure caused by injecting a liquidor a liquid / gas mix into the capsule, against a relief plate of a beverage production machine, wherein the capsule is provided with a flow control porous member (80), the flow control porous member (80) being positioned between at least a portion of ingredients (3) and the foil member (5). The flow control porous member provides a faster and more consistent flow of the liquid extract through the capsule and significantly reduces the resurgence of non-soluble solids.

Description

technical field [0001] The present invention generally relates to capsules for containing beverage ingredients, beverage production systems for use in conjunction with such capsules and methods for producing beverages based on ingredients contained in such capsules. Background technique [0002] Background of the invention is the field of capsules containing beverage or other food (eg soup) ingredients. By means of the interaction of these ingredients with the liquid, beverages or other foods, such as soups, can be produced. Interactions can be processes such as extraction, brewing / brewing, dissolving, etc. Such capsules are particularly suitable for containing ground coffee for the production of coffee beverages by passing pressurized hot water into the capsule and expelling the coffee beverage from the capsule. [0003] FR 1537031 does not describe individual capsules, but discloses a blister pack containing coffee powder. Since the two foil parts are sealed together at...
