Patent No. 5304384A: Rapid Cooling

Today in 1994, US Patent 5304384 A was issued, an invention of Cameron R. Murray and William J. Van der Meer, assigned to Labatt Brewing Company Limited, for their “Rapid Cooling.” Here’s the Abstract:

A process for preparing a fermented malt beverage wherein brewing materials are mashed with water and the resulting mash is heated and wort separated therefrom. The wort is boiled, cooled and fermented and the beer is subjected to a finishing stage, which includes aging, to produce the final beverage. The improvement comprises subjecting the beer to a cold stage comprising rapidly cooling the beer to a temperature of about its freezing point in such a manner that ice crystals are formed therein in only minimal amounts. The resulting cooled beer is then mixed for a short period of time with a beer slurry containing ice crystals, without any appreciable collateral increase in the amount of ice crystals in the resulting mixture. Finally, the so-treated beer is extracted from the mixture.

Patent No. 6051212A: Process For Producing Yeast Extract

Today in 2000, US Patent 6051212 A was issued, an invention of Hisao Kado, Takumi Shibata, Fujio Kobayashi, and Masaki Kubota, assigned to Sapporo Breweries Limited, for their “Process for Producing Yeast Extract.” Here’s the Abstract:

In accordance with the present invention, it is provided a method for producing a yeast extract with the improvement in the color and odor characteristic to yeast extract and with no modification of the useful substances such as amino acid, etc. compared with conventional yeast extract.

By a simple method in accordance with the present invention, color and characteristic odor can be removed, with almost no loss of the contents of useful substances such as amino acid, etc. from the yeast extract solution produced in a conventional manner. Because the resulting yeast extract can be mixed with other materials for use, the yeast extract is applicable to various fields, for example for cosmetic products and healthy foods other than seasonings, which expectantly enlarges the applicable range of the yeast extract.
