Clinical Dietetic Technician A.D.A. Role Delineation Verification, Carol S. Hilovsky

Loma Linda University Electronic Theses, Dissertations & Projects

The changing role of the clinical dietitian has resulted in evaluation and identification of the appropriate role for the clinical dietetic technician. In 1981 the American Dietetic Association published the Role Delineation for Entry Level Clinical Dietetics including the responsibilities for the clinical dietetic technician practice level. Research comparing actual role performance of clinical dietetic technicians to the role defined in the delineation study was not found in a review of the literature.

This research was conducted to verify the degree to which clinical dietetic technicians are performing tasks identified for their role and to identify educational deficiencies and/or excesses. …

Evaluation And Improvement Of Coagulation Properties Of Milk For Manufacturing, Leslie M. Okigbo

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

A rugged and sensitive instrument "Vatimer" was developed to evaluate the coagulation properties of milk in cheese vats. Microvolt signals from the instrument varied with standing-wave motion of milk, forces arising from coagulation, curd firming, curd syneresis and also clean-in-place spray forces. Curd firmness at cutting varied three to four fold in commercial Cheddar cheesemaking operations.

The Formagraph instrument was used to select individual cow milk samples with good and poor chymosin-coagulation characteristics from the Utah State University Holstein herd. Blending 50% good-, and 50% poor-coagulating samples did not improve average coagulation properties of poor samples. Higher chymosin concentration caused …

Survival Of Porcine Pepsin During Cheddar Cheese Making And Its Effect On Casein During Cheese Ripening, Gheyath H. Majeed

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

A modification of a linear diffusion test for measuring milk clotting enzymes at concentrations of 1 x 10^-4 to 1 x 10^-1 chymosin units/ ml was developed to permit quantitative assay of porcine pepsin in Cheddar cheese with a standard deviation of 6%. The amount of porcine pepsin retained in Cheddar cheese curd was dependent on pH of milk at setting. Milk at pH 6.6, 6.4, 6.2, and 6.0 was set with porcine pepsin, acidified with lactic acid and glucono-~-lactone and made into Cheddar cheese. After pressing the corresponding curd contained 0, 3.64+0 .12 %, 4.79+0.52%, and 5.94+0.30% …

Protein Recovery And Coagulation Properties Of Commercial And Fractionated Milk Clotting Enzymes, Khalida A. Shaker

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Protein recovery and coagulation properties of five commercial and fractionated milk clotting enzymes were studied. The fractionated enzymes were Sephadex G-100 fractions of the commercial enzymes. Milk clotting activity of each fraction was tested using Berridge substrate. All fractions from each preparation which had milk clotting activity as measured with the Formagraph were collected and pooled. These samples and the original enzyme preparations were used to coagulate milk. Percent of protein lost in whey was determined by Kjeldahl. Coagulation was followed using a spectrophotometer monitoring changes in apparent absorbance at 600 nm. Curd protein yields using the five original enzyme …

The Effect Of Dextrose Ingestion On Cardiovascular Endurance, Judith M. Axford

Loma Linda University Electronic Theses, Dissertations & Projects

This study was designed to investigate the effectiveness of dextrose on cardiovascular endurance. The subjects were nineteen male students enrolled at Loma Linda University in Riverside, California. The subjects were exercised to their maximum while being tested on the treadmill.· Subjects were each tested twice. Thirty minutes before exercising, they ingested one hundred grams of dextrose for one test and ten ounces of sugar-free Kool-aid for the second test. The difference in exhaustion times was then recorded.

The data indicated that dextrose ingestion decreased exhaustion time on the treadmill. Subjects were able to exercise for a longer period of time …

The Incidence Of Obesity In Lds College Women: The Effect Of Selected Physical Socio-Environmental Variables On Total Percent Body Fat In Two Populations Of Lds Women, Carrie Tanner Summers

Theses and Dissertations

The purpose of this study was to determine the effect of selected physical socio-environmental variables on total percent body fat. The sample population consisted of single, LDS, white women attending Brigham Young University (BYU) and California State University at Fullerton (CSUF). Significant data as well as trends that appeared were included in this paper.

From the data collected, it was concluded that the sample populations at BYU and CSUF were the same. The incidence of obesity was determined only among individuals attending both universities. The entire sample population mean was 22.19 percent. This percentage did not meet the obesity criteria. …
