The determination of n-nitrosoproline in cured meats

Creator:: Ivey, Francis James
Abstract:: A method is described for the determination of N-nitrosoproline (NOPRO) in cured meat products. NOPRO was extracted with ethyl acetate from a slurry of cured meat and water after the addition of ammonium sulfamate and acid. This nitrosamino acid was converted to the methyl ester and after further purification, it...

The stability of ascorbic acid in bottled cranberry-based beverages under home-use conditions

Creator:: Wong, Geoffrey K.
Abstract:: Commercially bottled, vitamin C-fortified, cranberry juice cocktail and cranberry-apple (cranapple) juice drinks were stored at 5°C under simulated home-use conditions. Ascorbic acid (AA) and dehydroascorbic acid (DHA) levels were evaluated over a period of seven days by high performance liquid chromatography (HPLC). Total vitamin C content was also determined by...

Stability and gel strength of meat emulsions made with prerigor, preblended beef and reduced salt levels

Creator:: Wiser, Cathy
Abstract:: The purpose of this study was to investigate the use of preblended, prerigor beef in reduced salt meat batters. The functional properties of water-holding capacity, fat binding and gel strength were evaluated. Proximate analyses (protein, moisture and fat contents) of all cooked samples were performed, in duplicate. The sternomandibularis muscle...

Extraction of lentil proteins and their use in supplementation of bread

Creator:: Idris, Nor Aini
Abstract:: The purpose of this study was to extract proteins from lentils for use in bread making to improve nutritional quality of bread. Three solvents, distilled water, 0.7 M NaCl and 0.05 M NaOH solutions, were used for extraction. Extractions were done at an alkaline pH near 10 for 30 min....

Influence of polyphosphates on the emulsifying capacity of milk and meat proteins

Creator:: Cummins, Armando
Abstract:: The influence of polyphosphates upon the emulsification of enzymatic hydrolyzates of casein and lactalbumin and upon salt-soluble meat proteins was determined by a model system in which oil-in-water emulsions were formed. Sodium acid pyrophosphate, sodium tripolyphosphate and sodium hexametaphosphate were mixed together in a weight ratio of 4:2:4, respectively, to...

Gel electrophoretic analysis of the protein changes in ground beef stored at 2⁰C

Creator:: Xiong, Youling
Abstract:: A study was completed to determine the extent of the protein changes occurring in ground beef stored at 2°C for 10 days. Sections of semitendinosus muscle were obtained immediately after the slaughter of three beef animals. Each section was divided into two equal portions, one of which was ground and...

Pressurization of prerigor beef muscle and its effect on the solubilization of myofibrillar proteins

Creator:: Nwafor, Oguguo Ebisi
Abstract:: Investigations were conducted to evaluate some of the changes occurring in the myofibrillar proteins, particularly solubility properties, resulting from the hydrostatic pressurization (15,000 psi, 2-3 min, 40°C) of prerigor semitendinosus and longissimus dorsi beef muscles. Both pressurized muscles showed a sharp decline in pH (~0.9 unit) as the result of...

The effect of prerigor electrical stimulation pH decline, protein solubility and water holding capacity in beef muscles

Creator:: Elkhalifa, Elamin Abdalla
Abstract:: This study was designed to investigate the rate of pH decline, changes in protein solubility and in the water-holding capacity (WHC) of beef muscles subjected to pre-rigor electrical stimulation. Samples for the experiment were obtained from animals slaughtered at the Meat Science Laboratory, Oregon State University. Nine good quality steers...

Proteolytic and chemical changes of some minor nitrogen compounds and extra protein of bovine muscle during aging

Creator:: Petropakis, Heracles John
Abstract:: Investigations were conducted to determine whether the low molecular weight nitrogen compounds and the extra protein complex of bovine psoas major muscle were altered during a 12-day aging period. Electrophoretic studies of soluble proteins either before or after gel filtration on Sephadex G-25 columns indicated that the soluble proteins were...

Effect of prerigor pressurization on postmortem biochemical changes in beef muscle

Creator:: Elkhalifa, Elamin Abdalla
Abstract:: Prerigor pressurization of bovine semimembranosus muscle at 103.5 MNm⁻² (15,000 psi) for two min at 35°C significantly decreased (P<0.01) muscle pH, and significantly (P<0.01) increased the rate of glycogen degradation during the first 4 hr postmortem. Glycogen levels of pressurized muscle were significantly (P<0.01) lower than those of the control...
