Utah Red Raspberry Jam: The Effects Of Formulation, Heating, And Time On Color, Flavor, Texture, And Antioxidant Capacity, Jennifer Leigh Chase
Utah Red Raspberry Jam: The Effects Of Formulation, Heating, And Time On Color, Flavor, Texture, And Antioxidant Capacity, Jennifer Leigh Chase
Theses and Dissertations
The amount and type of antioxidants present in raspberries is dependent upon cultivar, ripeness, and growing conditions. Previous research on raspberry jam has reported some color, antioxidant, and flavor loss after processing and storage, though it is unknown to what extent similar changes will occur in raspberries grown in Utah. Sugar concentration and heating temperature as well as storage time were evaluated in an effort to maximize color retention, flavor, antioxidant content, shelf life, and consumer acceptance of Utah-grown raspberry jam. Four types of jams were processed in two batches each: low-sugar (40-42 Brix) and typical sugar (65-68 Brix) at …
Reading And Listening To Music Increase Resting Energy Expenditure During Indirect Calorimetry In Healthy Adults , Blaire Snell
Reading And Listening To Music Increase Resting Energy Expenditure During Indirect Calorimetry In Healthy Adults , Blaire Snell
Theses and Dissertations
The Academy of Nutrition and Dietetics has developed an evidence analysis library (EAL) for Nutrition and Dietetics professionals. The EAL is updated by members through workgroups consisting of experts in their fields, most often in response to unanswered questions. One such question is: what kinds of activities can be done during the rest period of an indirect calorimetry test in a healthy population? The objective of our study was to determine if listening to self-selected relaxing music or reading on an electronic device or a magazine effects resting energy expenditure (REE) as measured by an indirect calorimetry test in a …
Effect Of Enrichment-Bleaching And Low Oxygen Atmosphere Storage On All-Purpose Wheat Flour Quality, Jonathan Myers Swindler
Effect Of Enrichment-Bleaching And Low Oxygen Atmosphere Storage On All-Purpose Wheat Flour Quality, Jonathan Myers Swindler
Theses and Dissertations
All-purpose wheat flour is a useful long-term storage commodity, but is subject to off-odor formation. Although flour stored in a low oxygen atmosphere should inhibit rancid odor formation, it elicits consumer complaints about odor. The purpose of this study was to examine off-odor development in all-purpose wheat flour during ambient and elevated storage by determining the effect of low oxygen atmosphere and enrichment-bleaching on quality as measured by, free fatty acids (FFA), flour descriptive sensory analysis, conjugated dienes, headspace volatiles, bread consumer sensory analysis, color, loaf volume, and vitamin analysis. Enriched, bleached (EB) and unenriched, unbleached (UU) flour was stored …
The Protective Effect Of Antioxidants On Vitamin A Stability In Nonfat Dry Milk During Thermally Accelerated Storage, Amalie Brown Kurzer
The Protective Effect Of Antioxidants On Vitamin A Stability In Nonfat Dry Milk During Thermally Accelerated Storage, Amalie Brown Kurzer
Theses and Dissertations
Two studies were conducted to determine the relative effect of various combinations of antioxidants on vitamin A oxidation and isomerization in nonfat dry milk (NDM). In the first study, one lot of pasteurized unfortified skim milk was divided, fortified with vitamins A and D and one of 11 antioxidant treatments, and spray dried. A control batch from the same lot was also fortified with vitamins A and D and spray dried. Samples were analyzed for total vitamin A bioactivity after zero, one, and two weeks of storage. After two weeks at 50°C, the only NDM samples that did not experience …
Emergency Preparedness In Utah Households With Emphasis On Water And Food Storage Conditions, Stephanie Rae Gerla
Emergency Preparedness In Utah Households With Emphasis On Water And Food Storage Conditions, Stephanie Rae Gerla
Theses and Dissertations
Emergency preparedness steps taken by individuals in Utah households were evaluated in 3 studies. Study 1 evaluated the 2011 landline and cell phone Behavioral Risk Factor Surveillance System Survey and General Preparedness Optional Module results from two states, Louisiana and Utah, to find factors from demographic and medical data that can be used to predict emergency preparedness in individuals. Stepwise logistical regression analysis ascertained the ability of chosen variables to predict individuals' preparedness. The rate of prepared individuals was lower if they were between the ages of 18 to 54 years, when compared to the reference age group of 65 …
College Students' Fruit, Vegetable, And Sugar Sweetened Beverage Intake According To Dinner Group Participation, Erica Nicole Hansen
College Students' Fruit, Vegetable, And Sugar Sweetened Beverage Intake According To Dinner Group Participation, Erica Nicole Hansen
Theses and Dissertations
Objective: To compare the fruit, vegetable, and sugar sweetened beverage intake of college students who do and do not participate in dinner groups. Also, to determine if dinner group participation affects college students' perception of their overall health and adequacy of their fruit and vegetable intake. Design: A quantitative study of college students' fruit, vegetable, and sugar sweetened beverage intake through a one-time online survey. Setting: The survey was accessed via the internet at the time and place of students' convenience. Participants: A sample of 10,000 students was randomly selected from Brigham Young University's population of single students. 3,651 responded …
Construction And Performance Testing Of A Mixed Mode Solar Food Dryer For Use In Developing Countries, Sean Andrew Foster
Construction And Performance Testing Of A Mixed Mode Solar Food Dryer For Use In Developing Countries, Sean Andrew Foster
Theses and Dissertations
This study details the construction and performance testing of a mixed mode solar dryer using a combination of direct and indirect solar energy to dry food. One major benefit of this dryer design is its construction. It was simple to construct and was made with low cost materials, to make it feasible for use in developing countries. Previous research has identified several design factors that affect performance and efficiency: product loading density, number of trays, position of the absorber, and chimney type. Performance testing showed that chimney air speeds were not affected greatly by modifying the design aspects of the …
