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

The Relationship Of Macronutrient Intake With Growth In Children With Type 1 Diabetes Mellitus, Jessica L. Freeling

Electronic Theses and Dissertations

Child growth, a sensitive metric of overall health, results from the intricate interplay of nature and nurture. While the importance of nutrition in child growth is well established, growth trajectories exhibit substantial individual variability, influenced by sex and age, and often characterized by nonlinear patterns. Inadequate nutrition or disease can hinder growth, with potential for recovery upon proper nutrition or acute disease resolution. However, chronic disease or persistent malnutrition may lead to permanent growth perturbation. Notably, before the advent of insulin, chronic stunting and wasting were hallmarks of Type 1 diabetes mellitus (T1DM), though the specific impacts under modern standard …
