Impact Of Natural Cheese Composition On Proteolysis And Its Effects On Process Cheese Functionality, Natasha Scherber

Electronic Theses and Dissertations

Cheddar cheese is a commodity and a top-selling cheese in the United States. Enhanced flavors of cheddar cheese requires aging, which will allow proteolysis increase. Proteolysis is the most complex process that happens in cheese manufacturing and can be difficult to control because of environmental factors and compositional characteristics. The ripening process, which is the most timely and costly procedure in cheese manufacturing, can also be unpredictable when aspects, such as cheese composition, are changed. The coagulant is responsible for the first stage in proteolysis, which will produce large peptides. Small peptides are subsequentially produced during the second stage by …

To Study The Factors Influencing The Sampling Variability On Microbiological Analysis Of Milk And Whey, Ratul Kalita

Electronic Theses and Dissertations

Sampling and analysis are integral parts of dairy processing in quality control, process monitoring and control, and meeting regulatory standards. Accurate sampling is vital to avoid erroneous analysis results and interpretation. The sampling process depends on the appropriateness of sample collection, transportation, storage, and analysis conditions. The bacterial heterogeneity and cluster formation, structural heterogeneity of food, sample unit and size, frequency, and sampling methods, are also crucial in sampling. We aimed to evaluate the influence of sample volume, sampling frequency, and sampling methods in experimental processing lines of whole milk, skim milk, and whey. To standardize the experimental protocols, a …

A Process To Produce Lactose Phosphate From Dairy Byproducts And Used As An Alternative To Emulsifying Salts In Processed Cheese Food Manufacture, Khalid Ahmed Alsaleem

Electronic Theses and Dissertations

Lactose is the primary carbohydrate in most mammals' milk, commonly known as milk sugar. Milk permeate is a by-product of whey protein manufacturing through membrane technologies. It is cost-effective, available, and an excellent source of lactose. Sugar phosphorylation is a technique used to alter sugar's characteristics. It has numerous applications for developing dairy and food products. Lactose-6-phosphate (LP) is an organic compound that switches the hydrogen on lactose by monophosphate that has the potential to function as emulsifying salts (ES). ES, such as disodium phosphate (DSP) and trisodium citrate, have a critical effect on the emulsification characteristics of casein by …

Postprandial 25-Hydroxyvitamin D Response Varies According To The Lipid Composition Of A Vitamin D3 Fortified Dairy Drink, Aislinn F. Mccourt, Steven L. Mulrooney, Graham O'Neill, E. Dolores O'Riordan, Aifric M. O'Sullivan

Articles

In-vitro evidence suggests that the lipid component of foods alters vitamin D absorption. This single-blinded, cross-over postprandial study examined the effect of changing the lipid component of a 20 µg vitamin D3 fortified dairy drink on postprandial 25(OH)D concentrations. Participants consumed one dairy drink per visit: a non-lipid, a pre-formed oleic acid micelle, an olive oil and a fish oil dairy drink. There was a significant time*drink*baseline status effect on 25(OH)D concentrations (p = 0.039). There were no time*drink, time or drink effects on 25(OH)D in vitamin D sufficient participants (>50nmol/L). However, there was an effect of time …

Production Of Calcium Reduced Micellar Casein Concentrate Powders And Their Use In Process Cheese Products, Anil Kommineni

Hotline Number To Reach And Offer Agricultural Information To Plain Anabaptists During The Covid-19 Workplace Closures, Emily Shoop, Carly Becker, Nathan Glenn Briggs, Danielle Smarsh

Journal of Amish and Plain Anabaptist Studies

The Penn State Extension Animal Systems Team developed a toll-free hotline phone number to convey short educational messages to maintain contact and outreach to Pennsylvania’s animal producing Amish, Mennonite, and other plain Anabaptist populations. During the COVID-19 pandemic, Penn State Extension’s programming went largely online via webinars, online courses, and emails. This change in programming excluded a large sector of Pennsylvania farmers who do not use or have access to the internet and, as such, were liable to miss important best management practice reviews and timely updates in animal agriculture. The Animal Systems Hotline offered callers the choice to listen …

True Grit (1969) And Feminism: How It Succeeds And Why We Should Expect Better, Courtney Isom

Fall Student Research Symposium 2021

Hollywood Westerns are certainly not renowned for their contribution to feminist plots or characters, but True Grit (1969) is one of the more forward thinking movies with respect to women’s roles. However, the movie still portrays traditional power structures of patriarchy that undermine the female character’s autonomy. Looking at this film through the lens of both Critical Rhetoric and a Gender Diversity Perspective allows us to see the nuances of Mattie Ross' stand against oppressive traditional roles, while also examining the ways in which she is still dominated by discursive patriarchal practices. Celeste Condit’s gender diversity perspective encourages ditching traditional …

Understanding Milk Consumption Habits Among College Students In Order To Redesign Outreach, Stacey F. Stearns, Adam N. Rabinowitz

Journal of Extension

College students consume less dairy milk than in the past. Increased competition in the beverage aisle influences their choices. However, much of the population is not meeting the recommended intake guidelines for calcium. A survey of undergraduate college students with university dining plans focused on milk consumption habits, beverage choices, and student attitudes toward healthful foods and nutrition. Results are guiding Extension program educational outreach campaigns to college students. By focusing on the healthful and nutritional benefits of milk, Extension educators could increase consumption among college age consumers, and their long-term healthful outcomes.

Effects Of Probiotic Supplementation On Growth And Health Of Pre-Weaned Dairy Calves, Lily Bello

Honors Scholar Theses

Dairy calf immune development leaves calves susceptible to illness during the pre-weaned stage of life. Previous studies have shown that the use of probiotics during this time may result in increased growth rates and decreased incidence of illness, particularly diarrhea and scours. We hypothesized that by providing probiotics during the time from birth until weaning, calves on study would experience similar growth and health benefits. Neonatal calves (N=32) were provided milk replacer three times daily, with half of the calves receiving Probios® supplements mixed in with their first morning feeding. Growth and health measurements were collected weekly. Probiotic administration significantly …
