Social Ecological Food Systems: Sustainability Lessons From Maine Dairy Networks, Julia B. McGuire 2016 University of Maine

Social Ecological Food Systems: Sustainability Lessons From Maine Dairy Networks, Julia B. Mcguire

Electronic Theses and Dissertations

Milk production has played an integral role in the culture, landscape, and economy of Maine’s agriculture. Maine dairy farmers have faced numerous sustainability challenges to economic, environmental, and social aspects of their industry. Like many other complex social ecological systems, the Maine dairy industry faces a gap between scientific knowledge and actionable management or policy. A cultural dichotomy exists between conventional and organic farming. Shifting the focus from this binary, metrics such as social capital may play a key role in solving sustainability issues. Difficulties arise in the governance of complex social ecological systems when the scales of assessment ...

Study Of Rehydration Properties Of Powder Produced From Chelated Skim Milk, Kristina Ellice Tan 2016 California Polytechnic State University, San Luis Obispo

Study Of Rehydration Properties Of Powder Produced From Chelated Skim Milk, Kristina Ellice Tan

Master's Theses and Project Reports

Poor rehydration properties of skim milk powder (SMP) can impact processing efficiency and functionality in finished product applications. Rehydration can be split into four stages: wettability, sinkability, dispersibility, and solubility. Previous work has suggested that chelator addition during SMP manufacture leads to higher solubility compared to SMP without chelators. This study focuses on the addition of ethylene diamine tetraacetic acid (EDTA) or sodium citrate dihydrate (SCD) at concentrations of 5, 10, and 15 mM to skim milk prior to evaporating and spray drying. The objective of this investigation was to determine the effects of the chelator additions on each SMP ...


Comparison Of Foaming Properties Between Chelated Reconstituted Smp And Caseinates, Boya Liu 2016 California Polytechnic State University – San Luis Obispo

Comparison Of Foaming Properties Between Chelated Reconstituted Smp And Caseinates, Boya Liu

Master's Theses and Project Reports

Caseinate powders have been well accepted because of their foaming properties. In this study, 10% solution of reconstituted skim milk powder (SMP) chelated with sodium hexametaphosphate (SHMP) and trisodium citrate (TSC) at 1 mEq, 50 mEq, and 100 mEq were prepared to conduct a comparison with sodium caseinate, potassium caseinate, and calcium caseinate solutions. Foamability, foam stability as well as the preferential locations of αs-casein, β-casein and !-casein in their foams were analyzed. It was hypothesized that the foamability, foam stability and the preferential locations of these three caseins in the milk foams are different from treatment to treatment. Milk ...


Feasibility, Safety, Economic And Environmental Implications Of Whey-Recovered Water For Cleaning-In Place Systems: A Case Study On Water Conservation For The Dairy Industry, Yulie E. Meneses 2016 University of Nebraska-Lincoln

Feasibility, Safety, Economic And Environmental Implications Of Whey-Recovered Water For Cleaning-In Place Systems: A Case Study On Water Conservation For The Dairy Industry, Yulie E. Meneses

Dissertations & Theses in Food Science and Technology

Several countries around the world are facing the challenge of producing food with limited water resources for a growing population. This reality is forcing all sectors involved in the food supply chain to look for water conservation strategies that contribute to assure global food security. Besides water consumption, the food industry has to deal with wastewater generation; therefore, water reconditioning and reuse is an attractive solution to address both issues. The goal of this research was to demonstrate that high quality water can be recovered from whey, a by-product of the cheese making process, and reused in cleaning-in place (CIP ...


Separation And Characterization Of Reconstituted Skim Milk Powder Treated With Mineral Chelators, Amy Kringle 2016 California Polytechnic State University, San Luis Obispo

Separation And Characterization Of Reconstituted Skim Milk Powder Treated With Mineral Chelators, Amy Kringle

Master's Theses and Project Reports

The proteins found in milk are largely important in the functionality of many dairy products and dairy processes. The casein micelle system in milk is a complex and highly studied system. The micelle is thought to be a sponge like structure containing four caseins, αs1, αs2, β, and κ casein, and bound together with colloidal calcium phosphate. When a chelating agent such as a citrate, phosphate, or polyphosphate are added to milk systems, the CCP is bound to the chelator and removed from the micelle. It has been shown through past research that the use of calcium chelating ...

Honors Projects and Posters

A successful dairy farm develops individualized mastitis prevention and treatment programs using the milk quality profile of their herd. Port-Haven Dairy’s 230 Brown Swiss milking cow herd’s monthly DHIA somatic cell count data was used to select cows requiring milk sampling. Each quarter of selected cows and cows with clinical mastitis were sampled following a CMT paddle test. Milk samples were cultured and organisms that grew were identified visually and with subsequent tests. A composite sample was also cultured from each fresh cow to test for mycoplasma organisms. Eight positive staphylococcus aureus cows and zero positive mycoplasma cows ...

ADVS Faculty Publications

Information is lacking on preserving fish carcasses to minimize postmortem autolysis artifacts when a necropsy cannot be performed immediately. The purpose of this study was to qualitatively identify and score histologic postmortem changes in two species of freshwater fish (bluegill - Lepomis macrochirus; crappie - Pomoxis annularis), at varied time intervals and storage temperatures, to assess the histologic quality of collected samples. A pooled sample of 36 mix sex individuals of healthy bluegill and crappie were euthanized, stored either at room temperature, refrigerated at 4 C, or frozen at 20, and then necropsied at 0, 4, 24, and 48 h intervals. Histologic ...


Design Of A Mobile Shade And Cooling Structure For Grazing Dairy Herds, William Barbour, Ellen Moore, Jay McMillan 2016 University of Tennessee, Knoxville

Design Of A Mobile Shade And Cooling Structure For Grazing Dairy Herds, William Barbour, Ellen Moore, Jay Mcmillan

EURēCA: Exhibition of Undergraduate Research and Creative Achievement

The U.S. organic dairy industry has experienced significant growth in recent years: over 10% growth annually since 2009 and 14.5% from 2010 to 2011; total market share is approximately 5% in the United States. The USDA places certain requirements on diary products that are certified organic, some of which are aimed at grazing practices. One challenge farmers must overcome to comply is keeping the cows in optimum conditions in a free-range grazing scenario; poor conditions such as excessive heat can decrease milk production and pose an economic burden on the dairy. The proposed system intends to control environmental ...


Relationship Between Body Condition Score (Bcs) And Feed Efficiency In Lactating Dairy Cattle, Kara Maxwell 2016 Iowa State University

Relationship Between Body Condition Score (Bcs) And Feed Efficiency In Lactating Dairy Cattle, Kara Maxwell

Honors Projects and Posters

Increasing feed efficiency in dairy cattle leads to increased profitability. Feed efficiency in dairy cattle represents the balance between milk production and feed intake. It is desirable if a dairy cow can make more milk with less feed input. There is concern, however, that selecting for a more feed efficient cow might lead to cows that suffer extreme body tissue loss to meet the demands of increased milk production. To research this concern, the relationships between body condition score (BCS) observed during the last 130 days of first lactation and the first 45 days of second lactation and two measures ...

Partial Calcium Depletion During Membrane Filtration Affects Gelation Of Reconstituted Milk Protein Concentrates, H. Eshpari, R. Jiménez-Flores, P. Tong, M. Corredig 2016 University of Guelph

Partial Calcium Depletion During Membrane Filtration Affects Gelation Of Reconstituted Milk Protein Concentrates, H. Eshpari, R. Jiménez-Flores, P. Tong, M. Corredig

Phillip S. Tong

Milk protein concentrate powders (MPC) with improved rehydration properties are often manufactured using processing steps, such as acidification and high-pressure processing, and with addition of other ingredients, such as sodium chloride, during their production. These steps are known to increase the amount of serum caseins or modify the mineral equilibrium, hence improving solubility of the retentates. The processing functionality of the micelles may be affected. The aim of this study was to investigate the effects of partial acidification by adding glucono-δ-lactone (GDL) to skim milk during membrane filtration on the structural changes of the casein micelles by observing their chymosin-induced ...
