Abstract
A vegetable extract in the form of grains which dissolve instantaneously in water and which have a porous, continuous structure, a smooth surface and an apparent density of from 50 to 300 g/l. A process for the production of a vegetable extract as described above, which comprises extruding a vegetable extract in powder or paste form into a chamber where a subatmospheric pressure prevails, and cutting the extruded product into fragments.
Claims17
A water-soluble grain consisting of dehydrated extract of vegetable material selected from the group consisting of coffee, chicory, tea and herbal decoction, said grain having (a) a porous, cellular, internal structure encompassed by an essentially smooth surface skin, (b) an apparent density of from 50 to 300 g/l, (c) a moisture content of up to 6%;
- and (d) a resistance to crushing of between 2.5 and 7.5 Newtons.
A process for producing a water-soluble grain having a resistance to crushing of between 2.5 and 7.5 Newtons consisting of pressure extruding a thermoplastic vegetable material extract selected from the group consisting of coffee, chicory, tea and herbal decoction having a moisture content of up to 10% by dry weight at a temperature in the range from about 60.degree. to 125.degree. C. and under a pressure of from about 1 to 10 atmospheres into a chamber where a subatmospheric pressure of from 0.01 to 0.3 atmosphere prevails, and then cutting the extruded product into fragments.
A process for the production of a vegetable extract grain having a resistance to crushing of between 2.5 and 7.5 Newtons selected from the group consisting of coffee, chicory, tea and herbal decoction which consists of extruding at a temperature in the range from about 60.degree. to 125.degree. C. and under a pressure of from about 1 to 10 atmospheres a thermoplastic vegetable material selected from the group consisting essentially of edible powder and paste and containing up to 10% water into a chamber where a subatmospheric pressure of from about 0.01 to 0.3 atmosphere prevails, and cutting the extruded product into fragments.
