Preferential Binding Of Polyphenols In Blackcurrant Extracts With Milk Proteins And The Effects On The Bioaccessibility And Antioxidant Activity Of Polyphenols, Ting Mao, Fnu Akshit, Iresha Matiwalage, Subha Sasidharan, Caren Meyn Alvarez, Philip Wescombe, Maneesha S. Mohan
Dairy Science and Food Science Faculty Publications: 2022 to Present
Milk proteins are well-known delivery agents; however, there is no clear understanding of the competitive interactions of milk proteins with polyphenols in mixed complex systems. Here, we investigate the preferential competitive interactions of different polyphenols present in blackcurrant extract with milk proteins by quantifying the protein-bound polyphenols and comparing the factors affecting these interactions. In addition, bioaccessibility and antioxidant activity were studied after in vitro gastric digestion. Our results indicated that polyphenols from blackcurrant extracts were preferentially bound to caseins more than whey proteins, with noncovalent interactions causing secondary structural changes in the protein. The hydrophobicity and the charge of …

The Effect Of Soluble Soybean Polysaccharide Addition To Permeate Concentrate On Lactose Crystallisation, Growth And Recovery During Lactose Manufacturing, Venkateswarlu Sunkesula, Prafulla Salunke, Lloyd E. Metzger
Dairy Science and Food Science Faculty Publications: 2022 to Present
Lactose is manufactured from permeates of cheese whey, milk protein concentrate and a mix of both using a crystallisation process. Several factors, such as solute supersaturation, cooling rate and impurities, influence lactose crystallisation. This study focussed on the effect of soluble soybean polysaccharides (SSPS) on crystallisation during lactose manufacture from concentrated permeate solutions by evaluating lactose crystal growth and recovery with and without SSPS addition. Adding 0.1% (w/w) SSPS resulted in a significant difference (P > 0.05) in lactose crystal size and yield. The results suggest that using SSPS during lactose manufacturing from permeate concentrates could influence lactose crystallisation and recovery

Milk fat contains essential nutrients, including fat-soluble vitamins; short-, medium-, and long-chain with odd and branched chain fatty acids; essential amino acids; and calcium, which are all known for their bioactive properties. In addition, the incorporation of probiotics, which are known for their bioactive properties, could further enhance the products’ attributes. However, direct probiotic addition is known …
Impact Of Transglutaminase Treated Micellar Casein Concentrate And Milk Protein Concentrate On The Functionality Of Processed Cheese Product Slice Formulations, Prafulla Salunke, Lloyd E. Metzger
Impact Of Transglutaminase Treated Micellar Casein Concentrate And Milk Protein Concentrate On The Functionality Of Processed Cheese Product Slice Formulations, Prafulla Salunke, Lloyd E. Metzger
Dairy Science and Food Science Faculty Publications: 2022 to Present
Milk protein concentrate (MPC) is used as an ingredient in processed cheese product (PCP) formulations. However, its use can result in texture defects such as a soft body and restricted melting characteristics. The use of micellar casein concentrate (MCC), which has a higher level of casein and less serum protein, improves the texture of PCP. Further improvement in PCP products may be possible using transglutaminase (TGase), an enzyme that can crosslink proteins. This study aimed to determine the effect of TGase treatment of MPC and MCC retentates on the functionality of MPC and MCC when used in a PCP slice …

1. Invasive species management can benefit from predictive models that incorporate spatially explicit demographics and dispersal to guide resource allocation decisions.
2. We used invasive bigheaded carps (Hypophthalmichthys spp.) in the Illinois River, USA as a case study to create a spatially explicit model to evaluate the allocation of future management efforts. Specifically, we compared additional harvest (e.g. near the invasion front vs. source populations) and enhanced movement deterrents to meet the management goal of reducing abundance at the invasion front.
3. We found additional harvest in lower river pools (i.e. targeting source populations) more effectively limited population sizes upriver …

Whole Genome Sequencing For Identification Of Putative Causative Alleles For Hemochromatosis In Horses, Anna M. Rauber-Ramos
Whole Genome Sequencing For Identification Of Putative Causative Alleles For Hemochromatosis In Horses, Anna M. Rauber-Ramos
Schultz-Werth Award Papers
Hemochromatosis is liver disorder in which excess iron is stored in the liver, leading to iron overload and extensive liver damage that can prove fatal. Based on human precedence, a genetic cause for idiopathic hemochromatosis in horses is suspected. Two horses with hemochromatosis were whole genome sequenced, with variants in candidate genes prioritized in analyses of potential pathogenicity. No clear putative variants were found to be present in both horses, suggesting an etiology more complex than the initially suspected Mendelian inheritance. A heterozygous nonsense mutation in STEAP3 metalloreductase (STEAP3) was identified as a potential contributor to hemochromatosis in one of …
Impacts Of Eastern Redcedar Juniperus Virginiana L. On Avian Communities In Eastern South Dakota, Jay Holm
Impacts Of Eastern Redcedar Juniperus Virginiana L. On Avian Communities In Eastern South Dakota, Jay Holm
Schultz-Werth Award Papers
Eastern redcedar (ERC) (Juniperus virginiana L.) is the most rapidly spreading woody species in the Northern Great Plains due to fire suppression, planting in windbreaks, and overgrazing. Its encroachment has converted already fragmented and/or degraded grassland into woodland, and there is concern that it may negatively impact grassland-obligate/dependent avian species. In this study, I evaluated avian community composition between ERC-encroached and non-encroached grasslands in eastern South Dakota. Six sites each of encroached grassland and non-encroached grassland were selected. Bird surveys were conducted by performing point counts placed equidistantly along a transect for two years. Presence and abundance of each species …

Diets Of Invasive Channel Catfish Are Subsidized By Invasive Riparian Trees, Christopher A. Cheek, Brandon K. Peoples, Reuben R. Goforth
Natural Resource Management Faculty Publications
Russian olive (Elaeagnus angustifolia) is an invasive, fruit- bearing riparian tree that dominates riparian zones of the San Juan River in the southwestern United States. Previous research in this river suggests olive fruit is common in diets of invasive channel catfish (Ictalurus punctatus), but its energetic importance is unknown (i.e. critical for catfish fitness vs. incidental consumption). We assessed Russian olive consumption in channel catfish diets bimonthly for 1 year, hypothesizing that olive consumption would be greatest during periods of high olive availability and low benthic aquatic invertebrate availability. We found that catfish consumed olive fruit throughout the year and …

Dairy cows are predisposed to diseases during the postpartum period. Dystocia has been associated with increased risk for disease, which is likely the result of increased tissue trauma and stress during the prolonged parturition. To attenuate the inflammatory response seen in dystocic animals and improve well-being, we assessed the effects of a glucocorticoid, dexamethasone administered within 12 h after calving. Dystocia was defined as a difficult birth resulting in a prolonged calving (≥70 min after the amniotic sac appears) and was monitored through 3 video cameras in the close-up dry-cow pen. Cows meeting the dystocia definition were randomly …
Facing Into The Blizzard: Resiliency And Mortality Of Native And Domestic North American Ungulates To Extreme Weather Events, Jeff Martin
Natural Resource Management Faculty Publications
Unseasonably early blizzards in the northern Great Plains threaten large mammal populations unacclimated for variable and extreme winter conditions. This region averaged 22 blizzards per winter season during the 2010s, up from 6 during the 1960s, and is anticipated to average 32 blizzards by the 2050s. In early October 2013, the fatal Atlas Blizzard affected four livestock and captive species in 16 counties of western South Dakota. Expected one-week total death losses for the study area were estimated from national average background mortality rates: 161 cattle, 102 sheep, 9 horses, and 6 bison. However, observed death loss varied significantly (McNemar’s …

Metapopulation models may be applied to inform natural resource management to guide actions targeted at location-specific subpopulations. Model insights frequently help to understand which subpopulations to target and highlight the importance of connections among subpopulations. For example, managers often treat aquatic invasive species populations as discrete populations due to hydrological (e.g., lakes, pools formed by dams) or jurisdictional boundaries (e.g., river segments by country or jurisdictional units such as states or provinces). However, aquatic invasive species often have high rates of dispersion and migration among heterogenous locations, which complicates traditional metapopulation models and may not conform to management boundaries. Controlling …

Use Of Micellar Casein Concentrate And Milk Protein Concentrate Treated With Transglutaminase In Imitation Cheese Products—Unmelted Texture, Prafulla Salunke, Chenchaiah Marella, J. K. Amamcharla, K. Muthukumarappan, Lloyd Metzger
Dairy Science and Food Science Faculty Publications: 2022 to Present
The amount of intact casein provided by dairy ingredients is a critical parameter in dairy-based imitation mozzarella cheese (IMC) formulation because it has a significant effect on unmelted textural parameters such as hardness. From a functionality perspective, rennet casein (RCN) is the preferred ingredient. Milk protein concentrate (MPC) and micellar casein concentrate (MCC) cannot provide the required functionality due to the higher steric stability of casein micelle. However, the use of transglutaminase (TGase) has the potential to modify the surface properties of MPC and MCC and may improve their functionality in IMC. The objective of this study was to determine …
