Effect Of Adding Salt During The Diafiltration Step Of Milk Protein Concentrate Powder Manufacture On Mineral And Soluble Protein Composition, Vandna Sikand, Phillip S. Tong, John Walker Jul 2013

Effect Of Adding Salt During The Diafiltration Step Of Milk Protein Concentrate Powder Manufacture On Mineral And Soluble Protein Composition, Vandna Sikand, Phillip S. Tong, John Walker

Dairy Science

Milk protein concentrate (MPC) powders offer a great potential for use in an array of food applications because of their nutritional and functional values. However, MPC powders with protein content ≥80% (MPC80) exhibit poor solubility and hence restrict their potential use. The objective of this study was to determine the impact of adding salt during the diafiltration stage of MPC80 manufacture on solubility, turbidity, and to compare minerals and protein content of supernatants of ultracentrifuged samples with control sample. Three types of samples were produced: MPC80-C (control) with or without salt treatment, MPC80-Na (150 mM NaCl), and MPC80-K (150 mM ...


Milk Fat Globule Membrane Isolated From Buttermilk Or Whey Cream And Their Lipid Components Inhibit Infectivity Of Rotavirus In Vitro, K. L. Fuller, T. B. Kuhlenschmidt, M. S. Kuhlenschmidt, Rafael Jiménez-Flores, S M. Donovan Jun 2013

Milk Fat Globule Membrane Isolated From Buttermilk Or Whey Cream And Their Lipid Components Inhibit Infectivity Of Rotavirus In Vitro, K. L. Fuller, T. B. Kuhlenschmidt, M. S. Kuhlenschmidt, Rafael Jiménez-Flores, S M. Donovan

Dairy Science

Milk fat is encapsulated in a milk fat globule membrane (MFGM) that contains bioactive glycoproteins and glycolipids. The MFGM inhibits infectivity of rotavirus (RV), activity that has been attributed to its glycoprotein and carbohydrate components. However, previous studies of proteins and oligosaccharides in the MGFM have not accounted for all the bioactivity associated with the complete MFGM. The lipid fraction of the MFGM accounts for half of its composition by weight, and we postulate that this fraction should be tested by itself to determine if it plays a role in antiviral activity. Herein, the anti-RV activity of an organic extract ...

Rna Sequencing To Study Gene Expression And Single Nucleotide Polymorphism Variation Associated With Citrate Content In Cow Milk, A. Cánovas, G. Rincón, A. Islas-Trejo, R. Jiménez-Flores, A. Laubscher, J. F. Medrano Apr 2013

Rna Sequencing To Study Gene Expression And Single Nucleotide Polymorphism Variation Associated With Citrate Content In Cow Milk, A. Cánovas, G. Rincón, A. Islas-Trejo, R. Jiménez-Flores, A. Laubscher, J. F. Medrano

Dairy Science

The technological properties of milk have significant importance for the dairy industry. Citrate, a normal constituent of milk, forms one of the main buffer systems that regulate the equilibrium between Ca2+ and H+ ions. Higher-than-normal citrate content is associated with poor coagulation properties of milk. To identify the genes responsible for the variation of citrate content in milk in dairy cattle, the metabolic steps involved in citrate and fatty acid synthesis pathways in ruminant mammary tissue using RNA sequencing were studied. Genetic markers that could influence milk citrate content in Holstein cows were used in a marker-trait association study to ...


Effects Of Addition Of Somatic Cells To Caprine Milk On Cheese Quality, D. Sánchez-Macías, A. Morales-Delanuez, A. Torres, L. E. Hernández-Castellano, R. Jiménez-Flores, N Castro, A. Argüello Apr 2013

Effects Of Addition Of Somatic Cells To Caprine Milk On Cheese Quality, D. Sánchez-Macías, A. Morales-Delanuez, A. Torres, L. E. Hernández-Castellano, R. Jiménez-Flores, N Castro, A. Argüello

Dairy Science

Milk quality criteria and limits for somatic cell count (SCC) established in many countries make it difficult to maintain SCC of bulk tank goat milk below the threshold, due to non-infection factors linked to goat physiology. The aim of this study was to objectively verify the effects of SCC on fresh caprine milk cheese. Somatic cells were recovered from pooled healthy goat milk, and added to low SCC raw or pasteurised goat milk. Miniature cheeses were made and evaluated after 1 and 7 d. Somatic cells had a major effect on lipolysis, increasing free fatty acids regardless of whether milk ...
