Creator:: Scanlan, Richard A.
Abstract:: Milk, preheated at 82°C for 30 minutes, was heated to 146°C for four seconds (UHT-treated) and cooled to 5°C in a tubular heat exchanger. Immediately after heat treatment, 20 gallons of heated milk were vacuum distilled at 30°C in a semi-continuous, reduced pressure glass apparatus. Twenty gallons of non-heated milk...

Creator:: Khatri, Lakho Lilaram
Abstract:: Increasing interest has been shown in the irradiation sterilization and irradiation pasteurization of foods, but problems of off-flavors and odors are still unsolved, especially in the case of dairy products. From the flavor chemistry point of view, milk lipids are very highly susceptible to irradiation effects. Therefore, this investigation was...

Creator:: Anderson, Dale Fredrick
Abstract:: Numerous attempts have been made to identify the flavor compounds in Blue cheese, however, duplication of Blue cheese flavor has not yet been accomplished. Therefore, it was desirable to make a qualitative and quantitative investigation of Blue cheese flavor compounds and to study the effect of certain microorganisms on Blue...

Creator:: Bills, Donald D.
Abstract:: During the course of ripening, Cheddar cheese frequently develops a flavor defect described as fruity. Recent work has indicated that the use of certain starter cultures ultimately results in the development of the defect as the cheese ages. The flavor compounds responsible for the defect, however, have not been elaborated....

Creator:: Arnold, Roy Gary
Abstract:: Stale flavor development has been recognized as a defect of stored dry milk powders for several years. Recently, stale flavor development has been found to occur upon storage of sterilized concentrated milk, and is recognized as the principal limiting factor to commercial utilization of this process (Seibert, 1963). Some attempts...

Full Text:: storing them at 21 C. Subjective flavor panel evaluation of stored and fresh samples revealed

Creator:: Lillard, Dorris Alton
Abstract:: Food lipid systems are very complex and so is oxidative degradation that render them unpalatable for human consumption. The significance of lipid degradation and the key reactions involved have been thoroughly studied and are well understood today. This is not true, however, of the secondary products of the autoxidation reactions....

Creator:: Bills, Donald D.
Abstract:: The free fatty acids of Cheddar cheese are important components in the over-all flavor and aroma of the cheese. Although the more volatile fatty acids probably contribute most, there is reason to believe that the higher fatty acids may contribute, to some extent, in imparting typical flavor characteristics. Before the...
