Filed:

Dec 23, 1977

Appl. No.:

5/863724

Merton H. Hubbard - Hillsborough CA
Robert R. Phipps - San Francisco CA

Assignee:

Hills Bros. Coffee, Inc. - San Francisco CA

International Classification:

A23F 102

US Classification:

426467

Abstract:

A coffee roasting process for forming roasted coffee in which the green coffee beans are dry roasted by passage in a fluidized bed through a two-stage roaster. In the first stage, the beans are heated by a roasting gas for partial roasting and expansion of their cellular structure. Then, in the second zone, the beans are contacted with an independent roasting gas stream at a temperature of 515. degree. F. - 545. degree. F. to stabilize the open structure of the beans and to provide the desired dark brown color without burning. The second gas is supplied at a lower velocity and higher temperature than the first gas. The roasted coffee bean product is of low density while providing high yield of soluble solids.

Abstract:

The discovery of distinct modes of asymmetric catalysis has the potential to rapidly advance chemists' ability to build enantioenriched molecules. As an example, the use of chiral cation salts as phase-transfer catalysts for anionic reagents has enabled a vast set of enantioselective transformations. A largely overlooked analogous mechanism wherein a chiral anionic catalyst brings a cationic species into solution is itself a powerful method. The concept is broadly applicable to a number of different reaction pathways, including to the enantioselective fluorocyclization of olefins, and dearomatization of aromatic systems with a cationic electrophile-transferring (e.g., fluorinating) agent and a chiral phosphate catalyst. The reactions proceed in high yield and stereoselectivity. The compounds and methods of the invention are of particular value, especially considering the scarcity of alternative approaches.
