Polymorphism and growth behavior of blends of a high-melting fraction of milk fat (HMF) and sunflower oil (SFO) formulated with and without the addition of sucrose esters (SE) P-170, P-1670, and S-170 were studied by pulsed 1H NMR spectroscopy, X-ray diffraction, and polarized light microscopy. The effect of SE on the solid content maximum (S max) or crystallization rate was observed only at low supercooling (values of ΔT below 15°C). The Avrami k n decreased as n values increased, indicating that SE inhibited growth and impeded nucleation. Addition of SFO modified the polymorphic behavior of milk fat, most likely owing …
Type 2 Diabetes And The Risk Of Osteoporotic Hip Fracture In Utah Men And Women, Megan Bunch
Type 2 Diabetes And The Risk Of Osteoporotic Hip Fracture In Utah Men And Women, Megan Bunch
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Prior studies have unequivocally established a consistent association between osteoporotic hip fracture risk and type 2 diabetes mellitus. One reason this association still remains unclear is primarily due to the limited amount of research conducted in this area. The Utah Study of Nutrition and Bone Health (USNBH) is a case-control study conducted in Utah during the period of 1997-2001 to determine risk factors for osteoporotic hip fracture. All study participants (n = 2590) were determined from Utah residents 50-90 years of age. Cases were determined from 18 Utah hospitals during 1997-2001. Age and gender-matched controls were randomly selected from the …
The Integration Of The Nutrition Screening Tool With The Interdisciplinary Plan Of Care Form, Beth Hyatt
The Integration Of The Nutrition Screening Tool With The Interdisciplinary Plan Of Care Form, Beth Hyatt
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Literature Review
Undernutrition in the hospital setting has been shown to cause adverse outcomes. Screening for nutritional risk assists in the detection of undernutrition with subsequent early intervention to prevent further decline. While many nutrition screening tools exist, none are proven to detect undernutrition. Furthermore, many barriers exist for utilizing nurses as primarily responsible for screening patients for nutritional risk.
Background
A hospital reviewed the nutrition screening process and found that the form used and screening factors were insufficient to adequately detect undernutrition and appropriate referrals for dietitians.
Objectives
1) Determine if nursing compliance improved when the nutrition screening form …
Antimicrobial Properties Of Syringopeptin 25a And Rhamnolipids, Prerak T. Desai
Antimicrobial Properties Of Syringopeptin 25a And Rhamnolipids, Prerak T. Desai
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
The increasing bacterial resistance to available antibiotics requires the search for new antibacterial compounds to be broadened. This study investigated the antimicrobial properties of two secondary metabolites from fluorescent pseudomonads -- syringopeptin 25A, a lipodepsipeptide produced by Pseudomonas syringae pv. syringae, and a rhamnolipid mixture produced by Pseudomonas aeruginosa. The rate of antimicrobial action was determined by monitoring the rate of uptake of propidium iodide during exposure to the compounds. Inhibition was also confirmed by the microbroth dilution method to determine the MI Cs. Both the compounds inhibited growth of Gram-positive organisms, including Mycobacterium smegmatis, staphylococci, and …
Milk Intake In Early And Late Adulthood And Risk Of Osteoporotic Hip Fractures In Utah, Melanie Jean Slavens
Milk Intake In Early And Late Adulthood And Risk Of Osteoporotic Hip Fractures In Utah, Melanie Jean Slavens
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
The relationship between milk intake and risk of osteoporotic fractures is uncertain. Associations between milk intake and milk avoidance in relation to osteoporotic hip fracture were examined in the Utah Study of Nutrition and Bone Health (USNBH), a statewide case-control study. Cases were ascertained at Utah hospitals treating 98 percent of hip fractures during 1997-2001 and included 1188 men and women aged 50-89 years. Age- and gender-matched controls were randomly selected from Utah driver's license and Medicare databases (N= 1324). In-person interviews were conducted and participants reported frequency of milk intake per week at age 18 and during pregnancy among …

Crystallization studies are usually performed under isothermal conditions. Kinetic parameters characterizing the isothermal nucleation and growth processes can be obtained using classical nucleation and growth models. However, crystallization regimes found in nature, as well as those used in food and pharmaceutical processing, are rarely isothermal. Focusing on the nucleation stage, the approach followed in this work was to define a new parameter to characterize the driving force of nucleation, the supercooling-time exposure (β), which not only depends on the difference between the melting temperature (Tm) and the onset temperature of nucleation (Tc) ΔTc but also on the induction time of …

The water vapor permeability of fat barrier films has been associated with structural characteristics such as polymorphism, crystal size, and chemical composition, among others. However, no mechanistic models have been proposed to describe this relationship. In this study, we have determined the effects of processing conditions on the structure and physicochemical characteristics of four fats and their relationship to water vapor permeability. Results suggest that the solids' volume fraction and the domain size of the fat crystals seem to be the most important factors controlling water vapor migration. Moreover, materials with relatively large crystalline domains will yield malleable films with …

Nutty flavor in Cheddar cheese is desirable, and recent research demonstrated that 2- and 3-methyl butanal and 2-methyl propanal were primary sources of nutty flavors in Cheddar. Because malty strains of Lac-tococcus lactis (formerly Streptococcus lactis var. malti-genes) are characterized by the efficient production of these and other Strecker aldehydes during growth, this study investigated the influence of a malty L. lactis adjunct culture on nutty flavor development in Cheddar cheese. Cheeses made with different adjunct levels (0, 10(4) cfu/mL, and 10(5) cfu/mL) were ripened at 5 or 13 degrees C and analyzed after 1 wk, 4 mo, and 8 …
