An Evaluation Of Various Methods Of Roasting Whole Turkeys From The Frozen State, Kim Merida-Klemmedson Teot

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Methods of roasting frozen turkeys were evaluated to determine the optimum final internal temperature (71,77, or 82°C), the best low oven temperature method (foil tent vs roasting bag at 93,107, 121, and 135°c), and the best overall method (foil tent-121 °c, foil tent-163°C, roasting bag-163°c, foil wrap-232°C). The lower the final internal temperature the juicier and more tender the bird however, the 77°c final internal temperature is recommended because at the 71°c internal temperature, the thigh joint was unacceptably pink. Among the low oven temperature methods, birds roasted at 121°c received the highest average sensory scores. Birds roasted by the …

Too Much Of A Good Thing: Protein And A Dog's Diet, Dana H. Murphy

Pets Collection

Where the analysis done by Kronfeld on stress in dogs goes awry is in its implication that this conversion of protein reserves occurs during a mild or transient period of emotional turmoil. In point of fact, catabolism of proteins only begins after an extended duration of severe stress, as a consequence of an extreme condition like a long sled race or a bad infection. Therefore, a mildly stressed animal probably needs carbohydrates (and perhaps fats) far more than supplemental protein, since the former can be quickly and easily converted into bodily fuel. And in the case of the stress induced …

The Relationship Between Chemical Leavening Agents And Three Gastric Indices In Rats Subjected To Restraint Stress, Holly E. Bartelmann

Loma Linda University Electronic Theses, Dissertations & Projects

Male Sprague-Dawley rats fed diets of enriched yeast-leavened biscuits had no discernible advantage over those fed enriched chemically-leavened biscuits in three gastric indices studied. Restraint-stress administered to half of each dietary group was ineffectual in producing gastric ulcers, but did produce gastric color and appearance changes in fifty-eight per cent of the group receiving the chemically-leavened diet.

Thiamin and riboflavin-retention analyses done on various baked products produced conflicting results. Yeast-leavened products retained less thiamin and riboflavin than chemically-leavened products, but which chemical leavening agent was best for vitamin retention was different for each vitamin.

Dietary Effects On Pulmonary Function At 3780 Meters Altitude, Vicki Estes-Bruff

Loma Linda University Electronic Theses, Dissertations & Projects

Diet is known to affect acclimatization to altitude through the effect of carbohydrate on the respiratory exchange ratio. During the first three days following ascent to high altitude, spirometric indices including the forced vital capacity (FVC) and forced expiratory volume in one second (FEVp) decrease. The purpose of this study was to determine if dietary carbohydrate would influence these spirometric changes.

Seven healthy subjects were studied on two nutritionally complete diets at 335 meters and 3780 meters altitude in a cross-over design. The high carbohydrate diet (HI CHO) consisted of 76% of calories as carbohydrate, 12% as fat and 12% …

Designing An Experimental Diet (Low Fat, Low Linoleate) : Comparison Of Calculated And Analyzed Values For Total Lipid And Total Linoleate, Barbara F. Dickinson

Loma Linda University Electronic Theses, Dissertations & Projects

A five-day menu cycle, low in total fat and total linoleate, was designed to support research on the effects of dietary linoleate on lipid metabolism in healthy humans. The basal diet was lacto-ovo vegetarian, high in fruits and vegetables, with moderate amounts of grains, legumes, skim milk, and egg white.

Sixteen healthy male subjects were randomly divided into four groups of equal size. All received the basal diet and same total fat (30% of calories). Each of the four groups received a different calculated level of linoleate (18%, 14%, 6%, and 2% of calories). Safflower, corn, corn plus coconut, and …

The Effects Of Freezing And Heat Treatments On The Iga And Bacteria Count In Human Milk, Madeleine Sigman, Kenneth Burke, U. D. Register, O. Ward Swarner, Patricia Johnston, Gerald Shavlik

Loma Linda University Electronic Theses, Dissertations & Projects

Human milk has been recommended as the preferred food for preterm babies. Its unique immunological factors would be beneficial for these infants. The presence of possible microbial contamination raises the question of whether or not the mother's or donated milk should be used raw. Pasteurization would eliminate the need for costly and time consuming screening for potential pathogenic microorganisms prior to the use of raw human milk. However, heat treatment has been shown to destroy some of the immune factors in human milk. This study was designed to compare four treatments of frozen human milk and their effects on the …

Seasonal Variation In The Ability Of Milk And Whey To Support Lactic Culture Growth, Rick Cameron Norton

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Milk samples from two cheese plants with overlapping milk supplies were collected monthly for one year in an attempt to measure seasonal variation in the ability of milk and whey to support lactic culture growth . Treatments to control and minimize variability of milk or whey were evaluated to optimize stability in starter culture performance.

Raw milk samples were tested for somatic cell counts, activity tests (modified Horrall- Elliker), acid degree values, and total plate counts. Activity (modified Horraii-EIIiker) and inhibitory tests were also performed on pasteurized, pasteurized-vacuumized and high heat milk treatments.

Rennet whey (heated and unheated) was collected …

Improved Fermentation Process For Producing Methane From Cheese Whey, Abdulraman Y. Awad

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Two methods of single-stage fermentation were used to produce methane from whey. The first method involved batch fermentation in which the pH was automatically controlled at 7.0. In addition to pH control, the second method was characterized by introducing the substrate continuously into the fermenter along with dilution water to keep the organic acids at a non-toxic level.

The first method did not improve the production of methane compared to the batch fermentation in which a pH control system was not used (41). However, the second method showed that the concentration of organic acids has a major effect on limiting …

The Oxford Vegetarians - A Personal Account, Peter Singer

Human Health Collection

People coming together more or less by accident can have a catalytic effect on each other, so that each achieves more than he or she would have done alone. The Bloomsbury Group--G.E. Moore, Virginia and Leonard Woolf, E.M. Forster, J.M. Keynes, Vanessa and Clive Bell, Lytton Strachey and others--is a famous example. It would be immodest to suggest that the group of vegetarians who were together in Oxford from 1969 to about 1971 can compare with these illustrious figures; yet if the animal liberation movement ever succeeds in transforming our attitudes to other species, the Oxford Vegetarians may one day …
