This book was released on 2013-11-11 with total page 398 pages. Available in PDF, EPUB and Kindle. Book excerpt: Although the art of making cheese can be traced to prehistoric times, it has continued to evolve as modern civilization progressed. The advent of new technologies and instrumentation has brought exponential growth in the understanding of cheese components and their function. Even more recently, the evolution of cheesemaking has accelerated, driven by economic factors such as the establishment of the European Economic Community, the changing diet of developed countries, and the environmental and economic concerns associated with whey disposal. Molecular biology has revolutionized the development of starter and adjunct cultures as well as rennets, and genetics will make it possible to maintain ideal milk components for cheesemaking. The ability to accelerate traditional ripening procedures has altered the production of certain cheeses, and the emphasis on decreasing the intake of dietary fat, especially in the United States, has prompted the development of technology for producing low-fat cheeses with traditional texture and flavor. In assembling a distinguished group of participants for the symposium, "Chemistry of the Structure/Function Relationships in Cheese," we hoped to review the interplay of these trends and forecast the direction of future research. Contributors evaluated the current status of cheesemaking and highlighted the information that will be essential for new developments. They also focused the attention of agricultural and food chemists on the opportunities in cheese research and the potential contributions they might make to the future of cheese, a most valuable food product.

Book Synopsis The Effects of Modulating Hydrophobic Interactions in Milk Protein Systems by :
Download or read book The Effects of Modulating Hydrophobic Interactions in Milk Protein Systems written by and published by . This book was released on 2012 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Milk proteins associate with each other via several mechanisms including hydrophobic interactions. The properties of casein networks relies on the nature of these interaction forces (type, strength, number, and lifetime or relaxation behavior) between bonds within the network. Hydrophobic interactions have been included as one of the integral forces in recent models of the casein micelle. This aim of this thesis was to understand the role of hydrophobic interactions in several milk protein systems and how modifying these interactions would affect the formation, strength, and stability of the matrices. A series of salts, which mainly modifies hydrophobic interactions in protein systems by increasing or decreasing the solubility of a protein, was used as a tool to assess the role hydrophobic interactions play within several milk protein networks. Four model milk protein systems were studied: brine-salted cheese, process cheese, rennet milk gels, and protein stabilized foams. Salts were added to the protein systems at low and high concentrations. Chemical, rheological, textural and functional tests were used to assess how intrinsic or extrinsic factors affect the changes in protein-protein interaction strength. At low salt concentrations (0.25 M) electrostatic interactions decrease in milk protein systems. Cheese and gel systems exhibited lower hardness and storage modulus values. Foams demonstrated increased overrun, stability, and yield stress. At high salt concentrations 0.25 M, salt-specific effects were observed (i.e., strengthening or weakening hydrophobic interactions). Strengthening hydrophobic interactions in rennet gels and cheeses resulted in a more dense, brittle, and firmer protein network. Foams were more stable but weaker than the control. Weakening hydrophobic interactions produced softer, more meltable cheeses and prevented gelation. Foams were more voluminous but less stable and weaker. A deeper understanding of the role of hydrophobic interactions in milk protein systems helped to provide information how modulating hydrophobic interactions can influence cheese texture and melt properties, gelation and structure of rennet gels, and stability of protein stabilized foams. This research can lead to the development of milk protein products that employ functional ingredients/methods which alter hydrophobic interactions in proteins as tools to improve texture or functionality.

Book Synopsis Association of Low Molecular Weight Hydrophobic Compounds with Native Bovine Casein Micelles by : Manpreet Cheema
Download or read book Association of Low Molecular Weight Hydrophobic Compounds with Native Bovine Casein Micelles written by Manpreet Cheema and published by . This book was released on 2017 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Bovine milk contains ca.3.3 % proteins and casein proteins (s1-, s2-, - and -casein) account for 80% of the total protein content and exist in the form of colloidal particles known as casein micelles (D11=130 nm, ca. 1015 micelles /mL). Modified casein micelles are extensively investigated as encapsulating and delivery agents for various hydrophobic low molecular weight probes. The ability of modified casein micelles to bind hydrophobic probes may derive from the binding affinity of native casein micelles. The objective of the present work is to evaluate the binding properties of native casein micelles by evaluating their association with lipophilic phospholipids including sphingomyelins (SM) and phosphatidylcholines (PC) and active pharmaceutical ingredients (API) appearing in bovine milk. SM and PC are the major source of choline needed for growth and development in newborns. On the contrary, partitioning of undesired hydrophobic API, appearing in dosed dairy animal, to casein proteins can result in accumulation of these API residues in dairy products making them unsafe for human consumption.Native casein micelles were separated from raw skim milk of cows (mid lactation) by using size exclusion chromatography (SEC). The extractions of casein micelle fractions for hydrophobic and hydrophilic compounds followed by LC/MS analysis found 18 candidates including PC and SM showing at least 1000 times stronger peak areas associated with native casein micelles as compared to whey proteins and milk serum. Further analysis to characterize and quantify the association of PC and SM with native casein micelles of varying sizes separated from milk of cows in early, mid and late lactations was performed. LC/MS/MS analysis of extracted native casein micelles (diameters; 149 nm 87 nm) showed that the highest concentrations of the SM d18:1/22:0 (341.1 17.36 g) and PC 16:0/18:1(180.2 20.08 g) per gram of casein protein were found associated with the largest casein micelles (149 nm) isolated from late lactation milk and decreased as the casein micelle size decreased. A strong positive correlation was found between the distribution of SM, PC in raw whole milk, raw skim milk and casein micelle fraction. A decreased concentration of lipophilic SM, PC with decreasing casein micelle size was positively correlated to previously report decreasing proportions of -casein in smaller casein micelles due to decrease in hydrophobic domains available for interacting with hydrophobic compounds. Overall, contrary to the belief that lipophilic phospholipids such as SM and PC are present in significant amount in milk fat globule membrane in whole milk , 21-50% of most abundant SM and 16-25% of most abundant PC initially present in whole milk were found to appear in skim milk . Out of the total amount of most abundant SM and PC found in raw skim milk, 35-46% SM and 22-29% of PC were found associated with casein micelles. Another study to evaluate the association of hydrophobic API with native casein micelles was performed using in vivo and in vitro approach. The in vitro study conducted by spiking the raw bovine milk with hydrophobic API showed ca.66 % meloxicam, ca.30% flunixin, ca.34% of metabolite 5-hydroxy flunixin, ca. 50% thiabendazole and ca.33% of metabolite 5-hydroxy thiabendazole partitioned into casein micelles. The in vivo distribution of the API meloxicam, 5-hydroxy flunixin and 5-hydroxy thiabendazole in milk collected from dosed Holstein cows (mid lactation) showed ca.30% API associated with the casein micelles. Although, the fat fraction of the bovine milk is considered to be a suitable carrier for lipophilic compounds, less than ca. 5.0% of the recovered hydrophobic API were found in fat fraction. No linear relationship between the hydrophobicities of API and their partition into casein micelles was found. The present work supports the hypothesis that native casein micelles act as carriers for hydrophobic compounds appearing in bovine milk. The binding abilities of native casein micelles can be potentially used for increasing solubility of hydrophobic nutraceuticals in low fat foods. The significance of SM and PC for neurological development in infants, provide avenues for utilizing larger casein micelles in late lactation milk for fortification of infant formulas. Conversely, association of undesirable API with casein micelles in dairy milk needs to be taken into account for analysis of their residues in dairy products.

Download or read book Food Emulsifiers and Their Applications written by Richard W Hartel and published by Springer Science & Business Media. This book was released on 2013-04-17 with total page 315 pages. Available in PDF, EPUB and Kindle. Book excerpt: Food emulsions have existed since long before people began to process foods for distribution and consumption. Milk, for example, is a natural emulsion/colloid in which a nutritional fat is stabilized by a milk-fat-globule membrane. Early processed foods were developed when people began to explore the art of cuisine. Butter and gravies were early foods used to enhance flavors and aid in cooking. By contrast, food emulsifiers have only recently been recognized for their abil ity to stabilize foods during processing and distribution. As economies of scale emerged, pressures for higher quality and extension of shelf life prodded the de velopment of food emulsifiers and their adjunct technologies. Natural emulsifiers, such as egg and milk proteins and phospholipids, were the first to be generally utilized. Development of technologies for processing oils, such as refining, bleaching, and hydrogenation, led to the design of synthetic food emulsifiers. Formulation of food emulsions has, until recently, been practiced more as an art than a science. The complexity offood systems has been the barrier to funda mental understanding. Scientists have long studied emulsions using pure water, hydrocarbon, and surfactant, but food systems, by contrast, are typically a com plex mixture of carbohydrate, lipid, protein, salts, and acid. Other surface-active ingredients, such as proteins and phospholipids, can demonstrate either syner- XV xvi Preface gistic or deleterious functionality during processing or in the finished food.
