Solvent desorption dynamic headspace analysis of dairy product aroma compounds

Creator:: Rankin, Scott A.
Abstract:: A method for the assessment of volatile compounds in dairy products was developed using solvent desorption dynamic headspace sampling. The method was first applied to assay for diacetyl and acetoin in buttermilk. Major buttermilk volatiles recovered included diacetyl, acetic acid, and acetoin. Normalized detector responses were linear over the range...

Metabolic Implications of Red Raspberry Polyphenol Supplementation in High Fat-Fed C57BL/6J Mice

Creator:: Pierce, Gavin W.
Abstract:: Objective: Red raspberries are rich in polyphenols and fiber, relatively low in sugar compared with other fruits, and have been demonstrated to have favorable effects on energy homeostasis in mice. However, it has been unclear precisely which compounds within red raspberries possess the greatest bioactivity, and their mechanism of action....

Lactic streptococci and the fruity flavor defect of cheddar cheese

Creator:: Bodyfelt, F. W.
Abstract:: The tendency for certain single- and mixed-strain lactic starter cultures to develop a fruity and/or fermented off-flavor in ripening Cheddar cheese was traced to certain strains of Streptococcus lactis in the starter. A very intense fruity and/or fermented flavor developed in experimental cheeses when one particular S. lactis strain was...

Polyphenol oxidase of D'Anjou pears (Pyrus communis L.)

Creator:: Halim, David Husien
Abstract:: Stability, substrate and inhibitor specificity and electrophoretic properties of a crude polyphenol oxidase (PPO) preparation extracted from d'Anjou pears (Pyrus communis L.) were investigated. Levels of polyvinylpyrrolidone and pH of buffer for extraction were found to affect the specific activity of the extracted enzyme. An extract prepared with 1.5 g...

Sensory, microbiological, chemical, and rheological properties of reduced sodium Cheddar cheese

Creator:: Schroeder, Carla L.
Abstract:: The effect of reducing sodium chloride in Cheddar cheese was studied. Milled curd from a split-lot was salted at selected NaCl concentrations and analyzed through aging by sensory and rheological tests. Estimation of differences in compositional analysis, lactic acid populations, degree of proteolysis, water activity, and pH were also determined....

Lactic streptococci : the use of defined strains and bacteriophage-insensitive mutants in commercial manufacture of cheddar and cottage cheeses

Creator:: Thunell, Randall Kirk
Abstract:: Phage-insensitive Streptococcus cremoris starter strains were selected by assaying cheese whey against potential starter strains. Six strains were selected and characterized for continual use in cheesemaking. Upon phage-infection, strains were removed from the blend. Cheesemaking continued with remaining strains. A phage-insensitive, fast-acid-producing mutant of the infected strain was isolated and...

Rapid methods for the determination of post-pasteurization contamination of fluid milk and shelf-life prediction

Creator:: Isaza, Liliana Urrea
Abstract:: Several methods for estimation of the potential shelf-life of pasteurized fluid milk products were evaluated for their efficacy in this investigation. These methods were evaluated and compared to sensory, biochemical and bacteriological indices through a series of experiments conducted on different brands of commercially pasteurized fluid milk. The methods evaluated...

Rapid assay for Bacillus proteinases in raw milk as detected by a simple casein denaturation method

Creator:: Feijoo, Sergio C.
Abstract:: A casein agar diffusion method was developed to detect and quantify pertinent levels of proteinases produced in raw milk supplies by heat resistant Bacillus sporeformers. In order to optimize the required heat treatment conditions of raw milk samples, trials that involved a combination of different temperatures and times were evaluated....
