Compressed yeast is the sole substance present during autolysis except for an inert gas which may be in contact with the yeast. The yeast cell membrane product has dietetic and therapeutic properties.Type: GrantFiled: September 13, 1974Date of Patent: August 17, 1976Inventor: Henri Griffon

Patent number: 3963836Abstract: Yogurt and quark are prepared by a process wherein milk prior to culturing and coagulating is subjected to ultrafiltration to concentrate and to remove mineral salts with or without lactose removal. This process provides a high degree of flexibility in composition, and enhanced viscosity and increased yield. Additionally, quark made by the process is capable of being whipped to at least 200% overrun.Type: GrantFiled: January 3, 1975Date of Patent: June 15, 1976Assignee: Lever Brothers CompanyInventors: Alec Frank Henson, Gerard Marcel Marius Bret

Patent number: 3963837Abstract: Cheese is prepared by a process which involves ultrafiltering milk to produce a milk concentrate having substantially the composition of cheese and drying the concentrate to produce a dry product which can be subsequently rehydrated to is original water content and converted into cheese. Drying can be carried out in more than one step by partially drying, adding additives such as cream, lactic starters and rennet, and then completely drying. The process eliminates conventional draining of whey, and provides a dried product which can be preserved over extended periods of time and subsequently rehydrated and converted into cheese.Type: GrantFiled: February 27, 1974Date of Patent: June 15, 1976Inventors: Jean-Louis Joseph Maubois, Germain Pierre Charles Gabriel Mocquot, Louis Jean Vassal

Patent number: 3953610Abstract: The pH of milk is lowered to 4.5 to 5.5 by direct acidification without the necessity of cooling the milk to avoid local coagulation and casein precipitation by adding acid as a spray from above a portion of the milk surface undergoing high velocity mixing.Type: GrantFiled: January 31, 1975Date of Patent: April 27, 1976Assignee: Battelle Development CorporationInventor: Lawrence L. Little

Patent number: RE28810Abstract: A soy cheese having superior texture and body characteristics is made without milk solids by coagulating a fermented emulsion containing soy milk and a fat composition with about 0.05 to about 1.0 weight percent of a coagulant selected from the group consisting of aldonic acid lactones, uronic acid lactones, and mixtures thereof. A flavor producing proteolytic enzyme can be added to the soy milk before formation of the emulsion, to the emulsion prior to fermentation, or to the cooked curd without adversely affecting the texture and body of the resultant soy cheese.Type: GrantFiled: September 8, 1975Date of Patent: May 11, 1976Assignee: Fuji Oil Co., Ltd.Inventors: Haruo Tsumura, Yukio Hashimoto, Hayata Kubota
