Abstract
Abstract Dried and comminuted hop strobiles are mixed with an inert inorganic adsorbent, such as bentonite, and pressed to form cubes, slabs, pellets etc. which may be stored in containers under vacuum or in an inert gas atmosphere. The addition of the adsorbent improves the storage life of the pressed hops in terms of preserving the bitter substances, and further accelerates the disintegration of the pressed hops during wort boiling.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
75 words
A hop product pressed to form a shaped body comprising dried hop strobiles comminuted to a grain size of from about 2 - 10 mm and admixed with at least one inert inorganic adsorbent in a solid state, the adsorbent being selected from the group consisting of finely divided silica, silicates and aluminum oxide, the amount of the adsorbent being from about 10 to 30 percent, based on the total weight of hops and adsorbent.
Claim 2
Dependent Claim
75 words
A hop product pressed to form a shaped body comprising dried hop strobiles comminuted to a grain size of from about 2 - 10 mm and admixed with at least one inert inorganic adsorbent in a solid state, the adsorbent being selected from the group consisting of finely divided silica, silicates and aluminum oxide, the amount of the adsorbent being from about 10 to 30 percent, based on the total weight of hops and adsorbent.
Claim 3
Dependent Claim
29 words
Pressed shaped hops according to claim 1, wherein the amount of the adsorbent is from about 15 to 20 percent, based on the total weight of hops and adsorbent.
Claim 4
Dependent Claim
13 words
Pressed shaped hops according to claim 1, wherein the silicate adsorbent is bentonite.
Claim 5
Dependent Claim
49 words
Pressed shaped hops according to claim 3, wherein the silicate adsorbent is an alkali-activated bentonite having a specific surface of from about 30 to 50 m 2 /g, a pH of from about 6 to 8 and an ion exchange capacity of from about 20 to about 100 milliequivalents/g.
Claim 6
Dependent Claim
20 words
Pressed shaped hops according to claim 1, wherein said hops are packed in a substantially gas-impermeable container under sub-atmospheric pressure.
Claim 7
Dependent Claim
17 words
Pressed shaped hops according to claim 5, wherein the substantially gas-impermeable container is a sealed film envelope.
Claim 8
Dependent Claim
22 words
Pressed shaped hops according to claim 1, wherein said hops are packed in a substantially gas-impermeable container in an inert gas atmosphere.
Claim 9
Dependent Claim
17 words
Pressed shaped hops according to claim 7, wherein the substantially gas-impermeable container is a sealed film envelope.
Claim 10
Dependent Claim
91 words
Method of making pressed shaped hops comprising comminuting dried hops strobiles down to a grain size of from about 2 - 10 mm, mixing the dried and comminuted hops strobiles with at least one inert inorganic adsorbent in the solid state, the adsorbent being selected from the group consisting of finely divided silica, silicates and aluminum oxide, the amount of adsorbent being from about 10 to 30 percent based on the total weight of hops and adsorbent, and subsequently pressing said mixture through an apertured die to form a shaped body.
Claim 11
Dependent Claim
91 words
Method of making pressed shaped hops comprising comminuting dried hops strobiles down to a grain size of from about 2 - 10 mm, mixing the dried and comminuted hops strobiles with at least one inert inorganic adsorbent in the solid state, the adsorbent being selected from the group consisting of finely divided silica, silicates and aluminum oxide, the amount of adsorbent being from about 10 to 30 percent based on the total weight of hops and adsorbent, and subsequently pressing said mixture through an apertured die to form a shaped body.
Claim 12
Dependent Claim
27 words
Method according to claim 9, wherein the amount of the adsorbent is from about 15 to 20 percent, based on the total weight of hops and adsorbent.
Claim 13
Dependent Claim
21 words
Method according to claim 9 comprising packaging the pressed mixture in a substantially gas-impervious container, and evacuating and sealing said container.
Claim 14
Dependent Claim
34 words
Method according to claim 9, comprising filling the pressed mixture into a substantially air-impermeable container, evacuating said container, charging said container with an inert gas or an inert gas mixture, and sealing said container.
Claim 15
Dependent Claim
11 words
Method according to claim 9, wherein the silicate absorbent is bentonite.
Claim 16
Dependent Claim
46 words
Method according to claim 13, wherein the adsorbent is an alkali-activated bentonite having a specific surface of from about 30 to 50 m 2 /g, a pH of from about 6 to 8 and an ion exchange capacity of from about 20 to about 100 milliequivalents/g.
