Patent ID: 8420150

Claim:
A compacted product based on plant ingredients capable of generating a hot drink by contact with hot water, said compacted product being characterized in that: a) subject to a temperature or 120° C. for 20 min, it has a loss of volatile materials of between 2 and 10%, b) subject to a temperature ranging from 20° C. to 25° C. at a pressure of 40 megapascals, it has a mass loss by exudation of less than 0.1%, c) subject to a temperature ranging from 20° C. to 25° C. at a pressure of 100 megapascals, it has a mass loss by exudation of more than 0.2%, d) its resistance to crushing along a direction parallel to the axis of the largest length of the plane of largest section is between 20 and 70 Newtons, e) its density is between 0.6 and 0.95 g/cm 3 , f) its dry extract yield after decoction is less than 100% of the dry extract yield after decoction of the plant powder.
