Odor Evaluation And Gas Emission From Manure Of Dairy Heifers Fed High/Low - Forage Quality And High/Low-Concentrate Diets, Patrick A. Topper, Robin Brandt, Arlene Adviento-Borbe, Gustavo J. Lascano, Arlyn J. Heinrichs, Eileen F. Wheeler
Dairy Science
A heifer feeding trial evaluated the impact of high/low forage quality and high/low concentrate level nutrient-balanced diets on simultaneous odor and gas emissions from the manure. Gas concentration was determined using an infrared photoacoustic analyzer over a 24-hour period using a steady-state flux chamber setup containing urine:feces as-excreted from eight individual heifers. Odorous air samples were collected from chamber headspace and evaluated by six human assessors for pleasantness, intensity and detection threshold using a forced-choice dynamic olfactometer. Ammonia emission ranged from 0.64 to 3.94 mg NH3 cm-2 d-1 across diets. Average ammonia emission from the low concentrate (80% forage) diets …

The Milk Fat Globule Membrane As An Ingredient: Why, How, When?, Rafael Jiménez-Flores, Guillaume Brisson
The Milk Fat Globule Membrane As An Ingredient: Why, How, When?, Rafael Jiménez-Flores, Guillaume Brisson
Dairy Science
This paper presents a personal view on the potential applications of the milk fat globule membrane as an ingredient in the processed foods area. Several factors are of importance for this dissertation: the biological origin of the membrane, the voluminous literature on its individual components and their relationship with health and wellness, the biological role of milk in nutrition to mammals and the innovation on scientific tools being applied in many fields of chemistry and biology. We hope to give a glimpse of the reasons on why it is a good idea to use more efficiently the components of the …
Effect Of Processing On The Composition And Microstructure Of Buttermilk And Its Milk Fat Globule Membranes, Pierre Morin, Rafael Jiménez-Flores, Yves Pouliot
Effect Of Processing On The Composition And Microstructure Of Buttermilk And Its Milk Fat Globule Membranes, Pierre Morin, Rafael Jiménez-Flores, Yves Pouliot
Dairy Science
The effect of cream pasteurization on the composition and microstructure of buttermilk after pasteurization, evaporation and spray-drying was studied. The composition of milk fat globule membrane (MFGM) isolated from buttermilk samples was also characterized. Pasteurization of cream resulted in higher lipid recovery in the buttermilk. Spray-drying of buttermilk had a significant effect on phospholipid content and composition. After spray-drying, the phospholipid content decreased by 38.2% and 40.6%, respectively in buttermilk from raw or pasteurized cream when compared with initial buttermilks. Pasteurization of cream resulted in the highest increase in whey protein recovery in MFGM isolates compared with all other processing …

Flavor Partition And Fat Reduction In Cheese By Supercritical Fluid Extraction: Processing Variables, Jessica L. Yee, Hany Khalil, Rafael Jiménez-Flores
Flavor Partition And Fat Reduction In Cheese By Supercritical Fluid Extraction: Processing Variables, Jessica L. Yee, Hany Khalil, Rafael Jiménez-Flores
Dairy Science
Developing low-fat cheese with flavor to match that of full-fat cheese has been a challenge in the dairy industry. The objective of this investigation was to develop lower fat Cheddar and Parmesan grated cheese using supercritical fluid extraction (SFE) and characterize its flavor profile comparative to a full-fat product. Specifically, enabling flavor compound partition between the matrices of cheese and extracted lipids. Carbon dioxide (CO2) was the supercritical fluid for fat extraction. Extraction took place in a 500 mL SFE vessel using 100 g of grated cheese. Fractional factorial design was utilized to investigate two levels of treatment …
Influence Of Ph And Heat Treatment Of Whey On The Functional Properties Of Whey Protein Concentrates In Yoghurt, Isabelle Sodini, Jerry Mattas, Phillip S. Tong
Influence Of Ph And Heat Treatment Of Whey On The Functional Properties Of Whey Protein Concentrates In Yoghurt, Isabelle Sodini, Jerry Mattas, Phillip S. Tong
Dairy Science
Our aim was to investigate how two conditions of whey processing, pH and heat treatment, affect the physical properties of stirred yoghurts fortified to 45 g protein kg−1 with whey protein concentrates (WPC). Cheddar whey was heated at pH 6.4 or pH 5.8 at 72 °C for 15 s, eventually heated further at 82 or 88 °C for 78 s, ultrafiltered, and spray dried. Resulting WPC contained 38% protein; the denaturation level of the whey protein was 10–53%. There were significant (P
A Comparative Study Of The Fractionation Of Regular Buttermilk And Whey Buttermilk By Microfiltration, Pierre Morin, Yves Pouliot, Rafael Jiménez-Flores
A Comparative Study Of The Fractionation Of Regular Buttermilk And Whey Buttermilk By Microfiltration, Pierre Morin, Yves Pouliot, Rafael Jiménez-Flores
Dairy Science
The use of a ceramic microfiltration (MF) membrane for the fractionation of buttermilk and whey buttermilk obtained from pilot scale churning of cream and whey cream from industrial sources has been studied. Whey buttermilk contained comparable amounts of phospholipids compared to regular buttermilk but its protein content was lower due to the absence of caseins. However, it was found that lipid content of whey cream did vary significantly between lots resulting in important variations in the fat content of whey buttermilk. A twofold MF concentration of regular buttermilk doubled its phospholipids content whereas that of whey buttermilk was increased by …

Dairy Science
Dendritic cells (DC) are often arranged in planar layers in tissues with high antigenic exposure, such as skin and mucosae. Providing an en face view, this arrangement optimizes in situ analysis regarding morphology (even of individual dendrites), topographic distribution (regular/clustered) and quantification. The few reports on human genital DC usually utilize single markers and conventional sections, restricting immunolabelling only to cell parts sectioned by the cut. To better assess DC in situ, we labelled epithelial sheets, prepared from fresh cervix biopsies, with antibodies to major histocompatibility complex (MHC)-CII, CD1a and Langerin, revealing (with each of these markers) a dense …

Physical Properties Of Yogurt Fortified With Various Commercial Whey Protein Concentrates, Isabelle Sodini, John Montella, Phillip S. Tong
Physical Properties Of Yogurt Fortified With Various Commercial Whey Protein Concentrates, Isabelle Sodini, John Montella, Phillip S. Tong
Dairy Science
The effects of whey protein concentrates on physical and rheological properties of yogurt were studied. Five commercial whey protein concentrates (340 g kg−1 protein nominal) were used to fortify milk to 45 g protein kg−1. Fermentation was performed with two different starters (ropy and non-ropy). Resulting yogurts were compared with a control yogurt enriched with skim milk powder. The water-holding capacity of the yogurt fortified with skim milk powder was 500 g kg−1 and ranged from 600 to 638 g kg−1 when fortified with whey protein concentrates. Significant rheological differences have been noticed between the …

Bioguided Processing: A Paradigm Change In Food Production, Robert E. Ward, Heribert J. Watzke, Rafael Jiménez-Flores, J. Bruce German
Dairy Science
The effort to sequence the human genome, and subsequently to make the results publicly available, has created a new paradigm in the biological sciences. Now that we have access to the blueprint of our very structure and those of organisms from viruses to plants to animals, a mechanistic understanding of all the processes involved in our growth and metabolism is possible. Characterization of the genetic differences among us is underway, and should provide the information basis for a new approach to individual health. The challenge to the food industry will be to create product lines that will address individual dietary …

Determination Of The Sensory Attributes Of Dried Milk Powders And Dairy Ingredients, M. A. Drake, Y. Karagul-Yuceer, K. R. Cadwallader, G. V. Civille, P. S. Tong
Dairy Science
A standardized descriptive language for skim milk powder and dried dairy ingredients was developed. The lexicon was initially identified from a large sample set of dried dairy ingredients (138). A highly trained descriptive panel (n = 14) refined terms and identified references. Dried dairy ingredients (36) were then evaluated using the developed language. Twenty-one descriptors were identified for dried dairy ingredients. Seventeen flavors and tastes were identified in skim milk powders (27) with nine flavors/tastes observed in all skim milk powders. Dried dairy ingredients were differentiated using the language (P
