A method of preparing anactinic hop extracts comprising three stages: pre-purification of a liquid CO.sub.2 hop extract using liquid-liquid extraction to isolate pure humulones or alpha acids; isomerization/reduction of the humulones to obtain a mixture consisting of reduced isohumulones and non-iso ...

Patrick L Ting, Jay R Refling, Henry Goldstein: Hydrogenation of hop soft resins using CO.sub.2. Miller Brewing Company, Quarles & Brady, February 1, 2000: US06020019 (44 worldwide citation)

Carbon dioxide is used as a reaction solvent in the hydrogenation of organic compounds. The carbon dioxide is preferably a liquid or a supercritical fluid. The hydrogenation method can be used advantageously in methods for making tetrahydroiso-alpha-acids from alpha-acids, iso-alpha-acids, or beta-a ...

Donald H Westermann, Etzer Chicoye, Darrell R Hoffmann: Hop extract process and product. Miller Brewing Company, June 22, 1976: US03965188 (37 worldwide citation)

Hop extract in, e.g., hexane, pre-isomerized, optionally pre-reduced, is extracted with aqueous KOH to give potassium isohumulate of 80%+ and preferably 90%+ purity. The hexane phase containing the remainder of the isohumulones is stripped of solvent and is suitable for kettle addition. In order to ...

The over-pasteurization of a product in a tunnel pasteurizer can result when the normal movement of the product through the pasteurizer is delayed. Over-pasteurization is prevented by cooling the product in the pasteurizing zone to reduce its temperature to a temperature at which no appreciable past ...

John M Cowles, Henry Goldstein, Etzer Chicoye, Patrick L Ting: Process for separation of beta-acids from extract containing alpha-acids and beta-acids. Miller Brewing Company, Quarles & Brady, May 20, 1986: US04590296 (28 worldwide citation)

Beta-acids are separated from alpha-acids in a hop extract without using organic solvents by bubbling CO.sub.2 through an aqueous hop extract having a pH of about 9.6 to about 13 to lower the pH to about 8.5 to about 9.5 to precipitate the beta-acids and leave the alpha-acids in the extract.

Vinod K Chaudhary: High dietary fiber product. Miller Brewing Company, Quarles & Brady, July 27, 1982: US04341805 (26 worldwide citation)

A product for human consumption containing protein and having a high dietary fiber content and a low phytic acid content is produced by drying brewer's spent grain, milling the dried brewer's spent grain to obtain a ground product having particle sizes ranging from about 600 microns down to about 50 ...

Shirley Drake Tipton, Constance M Lee: Insulating sleeve for a beverage pitcher. Miller Brewing Company, Quarles & Brady, May 16, 1995: US05415305 (24 worldwide citation)

An insulating sleeve for a beverage pitcher is disclosed. The sleeve is a flexible jacket capable of surrounding the pitcher while allowing the pitcher handle to extend out through the side. The jacket also has an open top to permit the pitcher's pour spout to extend out of the top, and an open bott ...
