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 ...

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 ...

Developing A Milk Quality Program For A Dairy Herd, Sabrina Portner

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 ...


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 ...

Short Communication: Effect Of Storage Temperature On The Solubility Of Milk Protein Concentrate 80 (Mpc80) Treated With Nacl Or Kcl, V. Sikand, P.S. Tong, J. Walker, T. Wang, L.E. Rodriguez-Saona

Dairy Science

A previous study in our laboratory showed that addition of 150 mM NaCl or KCl into diafiltration water improved the solubility of freshly made milk protein concentrate 80 (MPC80). In the present study, the objectives were (1) to evaluate the solubility of NaCl- or KCl-treated MPC80 samples kept at varying temperatures and then stored for extensive periods at room temperature (21°C ± 1°C); and (2) to determine if MPC80 samples stored at different temperatures and protein conformation can be grouped or categorized together. Freshly manufactured MPC80 samples were untreated (control), processed with NaCl, or processed with KCl. One ...

The New Safety Net: Dairy Margin Protection Program Participation And Payouts, R. Reid 2016 Kansas State University, Manhattan

The New Safety Net: Dairy Margin Protection Program Participation And Payouts, R. Reid

Kansas Agricultural Experiment Station Research Reports

The Dairy Margin Protection Program created by the 2014 Farm Bill offers a new risk management option available for dairy producers. By “insuring” a margin between the price of milk and the cost of feed inputs, producers can have protection from declining milk prices, rising feed costs, or both. More than half of the dairies in the U.S. participated in at least the catastrophic level of coverage for 2014, which locks them into participating through 2018 when a new Farm Bill is written. Coverage level and production history enrolled can change year to year however; therefore, each year producers ...


Evaluating An Ultrasonic Flaw Detector-Based Method To Characterize Solubility Of Whey Protein Concentrate, M. Hauser, J. Amamcharla 2016 Kansas State University, Manhattan

Evaluating An Ultrasonic Flaw Detector-Based Method To Characterize Solubility Of Whey Protein Concentrate, M. Hauser, J. Amamcharla

Kansas Agricultural Experiment Station Research Reports

One of the important characteristics of powders is their ability to quickly break down and disperse. Currently, the dairy foods industry does not have a reproducible method that can quantify this behavior. A previously developed method for an ultrasonic flaw detector was used to see if an ultrasound could characterize the dissolution of whey protein concentrate with a protein content of 80% (WPC80). For this study, an ultrasonic flaw detector equipped with a 1 MHz immersion transducer was operated in a pulse-echo mode. WPC80 was aged at 25°C and 40°C for 3 weeks. After powder addition, ultrasound, focus ...


Use Of Evaporative Cooling Systems And Their Effects On Core Body Temperature And Lying Times In Lactating Dairy Cattle, Jared R. Johnson, Michael Brouk, L. Mendonca, J. P. Harner 2016 Kansas State University, Manhattan

Use Of Evaporative Cooling Systems And Their Effects On Core Body Temperature And Lying Times In Lactating Dairy Cattle, Jared R. Johnson, Michael Brouk, L. Mendonca, J. P. Harner

Kansas Agricultural Experiment Station Research Reports

A study was performed to assess the effect of an evaporative cooling system on respiration rates, rear udder temperature (Tu), core body temperature (CBT), and resting time in lactating dairy cows. Cows were divided into two treatment groups and rotated between two facilities. Cows were either housed in a bedded pack barn (PACK) equipped with an evaporative cooling system (Cyclone fans, Chippewa Falls, WI) or a tie-stall barn (TIE) equipped with cooling cells. Cows housed in PACK had two cooling treatments: FAN (Cyclone fans only, no fog); and FANFOG (Cyclone fans and fog on). Groups of cows rotated between ...


The Why’S, What’S, And How’S Of Timed Artificial Insemination Programs, J. Stevenson, L. Mendonca 2016 Kansas State University, Manhattan

The Why’S, What’S, And How’S Of Timed Artificial Insemination Programs, J. Stevenson, L. Mendonca

Kansas Agricultural Experiment Station Research Reports

This report summarizes the benefits of using timed artificial insemination (AI) programs in lactating dairy cows. Since its beginnings, use of Ovsynch has penetrated the dairy industry and is most prevalent in the Midwest and Northeast regions of the U.S. The timed AI program benefits farms that have difficulties with heat detection. Heat detection challenges can occur because of inadequate observation or poor expression of heat associated with footing conditions. Explanation of mechanisms associated with hormone injections are presented to justify the success of currently recommended timed AI programs.
