Available in PDF, EPUB and Kindle. Book excerpt: Heat stability of milk concentrates may increase by removal of whey proteins. In this thesis, physico-chemical changes caused by partial whey protein removal by microfiltration (MF) were evaluated. The impact of these changes on the processing properties of retentates, especially heat stability, was also assessed. Ultrafiltration (UF) and MF were compared to establish the effect of protein composition, while maintaining the same protein concentration in the milk dispersions. Results demonstrated that changes on heat coagulation time (HCT) were due to the reduction of whey proteins. However, all treatments showed better stability than what is reported in the literature. It was hypothesized that the differences were due to the processing history and reconstitution conditions of the concentrates used in previous works. Diafiltration (DF) using water or permeate (PF) was also tested, to determine if a further increase in the ratio of protein to other solids may have an impact on the heat stability of the milk concentrates. At the same concentration factor, DF had a major impact on retentates composition when compared to UF and MF; however, this difference could not only be attributed to a decrease in lactose and ions, but also to an increase in pH. The analysis of the heat-induced complexes residual in the unsedimented fraction after UHT reinforced the positive impact of DF on heat stability, with the sample presenting fewer aggregates and with smaller sizes compared to UF or MF milk concentrates. Because calcium chelators are important in obtaining shelf stable products in protein concentrates subjected to high heat treatments, the impact of these salts at different concentrations and pH on the stability of a fresh microfiltered concentrate was evaluated. As the original sample was quite stable, no major changes were observed in short period of time. The results stressed, once again, the effect of processing history, and the difference in processing functionality between fresh and reconstituted concentrates. Indeed the present results were in contrast with literature reports. The work in this thesis contributes to a better understanding of the differences in processing functionality between milk protein concentrates depending on their processing history. This is critical to improved utilization of the concentrates in high protein nutritional beverages.

Available in PDF, EPUB and Kindle. Book excerpt: Food proteins are of great interest, not only because of their nutritional importance and their functionality in foods, but also for their detrimental effects. Although proteins from milk, meats (including fish and poultry), eggs, cereals, legumes, and oilseeds have been the traditional sources of protein in the human diet, potentially any proteins from a biological source could serve as a food protein. The primary role of protein in the diet is to provide the building materials for the synthesis of muscle and other tissues, and they play a critical role in many biological processes. They are also responsible for food texture, color, and flavor. Today, food proteins are extracted, modified, and incorporated into processed foods to impart specific functional properties. They can also have adverse effects in the diet: proteins, such as walnuts, pecans, almonds, and cashews, soybean, wheat, milk, egg, crustacean, and fish proteins can be powerful allergens for some people. Applied Food Protein Chemistry is an applied reference which reviews the properties of food proteins and provides in-depth information on important plant and animal proteins consumed around the world. The book is grouped into three sections: (1) overview of food proteins, (2) plant proteins, and (3) animal proteins. Each chapter discusses world production, distribution, utilization, physicochemical properties, and the functional properties of each protein, as well as its food applications. The authors for each of the chapters are carefully selected experts in the field. This book will be a valuable reference tool for those who work on food proteins. It will also be an important text on applied food protein chemistry for upper-level students and graduate students of food science programs.
Download or read book Milk Proteins written by C.A. Barth and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 318 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book reviews the state of knowledge and progress of research on food proteins, and in particular, milk proteins. Its basis is the Symposium on Milk Proteins that was held at the Federal Dairy Research Centre in Kiel, FRG, in June, 1988. Scien tists from around the world attended and addressed pure, as well as applied fields of protein research and technology. This book is divided into five sections, each adapted from the symposium's invited lectures, short communications, and poster presentations. New criteria for the "bio logical value" of dietary proteins and their relationships are considered according to: - Milk Proteins and Nitrogen Equilibrium - Milk Proteins and Ligands - Milk Proteins: Structural and Genetic Aspects - Milk Proteins: Technological and Functional Aspects - Milk Proteins and Clinical Nutrition Generally, different dietary proteins are classified according to their "biological value," i.e., their capacity to cause different retention of nitrogen in the body. But we think there are other intriguing leads worth studying that may help to identify which dietary proteins are best recommended for specific dietary situations or clini cal conditions. In addition, we have taken into consideration new fields such as attempts to determine the three-dimensional structure of proteins using two-dimensional NMR spectroscopy, and the application of genetic engineering to the lactating cell. In other words, we are on the way to the transgenic cow with customized milk constituents and composition.
Download or read book Emerging Dairy Processing Technologies written by Nivedita Datta and published by John Wiley & Sons. This book was released on 2015-06-22 with total page 361 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fluid milk processing is energy intensive, with high financial and energy costs found all along the production line and supply chain. Worldwide, the dairy industry has set a goal of reducing GHG emissions and other environmental impacts associated with milk processing. Although the major GHG emissions associated with milk production occur on the farm, most energy usage associated with milk processing occurs at the milk processing plant and afterwards, during refrigerated storage (a key requirement for the transportation, retail and consumption of most milk products). Sustainable alternatives and designs for the dairy processing plants of the future are now being actively sought by the global dairy industry, as it seeks to improve efficiency, reduce costs, and comply with its corporate social responsibilities. Emerging Dairy Processing Technologies: Opportunities for the Dairy Industry presents the state of the art research and technologies that have been proposed as sustainable replacements for high temperature-short time (HTST) and ultra-high temperature (UHT) pasteurization, with potentially lower energy usage and greenhouse gas emissions. These technologies include pulsed electric fields, high hydrostatic pressure, high pressure homogenization, ohmic and microwave heating, microfiltration, pulsed light, UV light processing, and carbon dioxide processing. The use of bacteriocins, which have the potential to improve the efficiency of the processing technologies, is discussed, and information on organic and pasture milk, which consumers perceive as sustainable alternatives to conventional milk, is also provided. This book brings together all the available information on alternative milk processing techniques and their impact on the physical and functional properties of milk, written by researchers who have developed a body of work in each of the technologies. This book is aimed at dairy scientists and technologists who may be working in dairy companies or academia. It will also be highly relevant to food processing experts working with dairy ingredients, as well as university departments, research centres and graduate students.

Download or read book Milk Proteins written by Isabel Gigli and published by BoD – Books on Demand. This book was released on 2016-09-07 with total page 298 pages. Available in PDF, EPUB and Kindle. Book excerpt: Milk proteins have nutritional value and extraordinary biological properties. Research over the last decades has provided new insight into the structure and the function of milk bioactive peptides. Some of these peptides are delivered directly into milk, and some are encrypted in major proteins such as caseins and lactoglobulins. These peptides have antimicrobial functions modulating the gut microflora. Even when milk is undisputedly the first food for mammals, milk proteins sometimes can be a health threat, either because of allergic reaction or because of toxicity. In this regard, in vitro studies showed donkey's casein and major whey proteins to be more digestible than cows' for human consumption. In this book, readers will find updated research on the major milk proteins' structure, bioactive peptides, milk protein allergy, therapeutic strategies, and chemical markers that can be used to detect cow milk intolerance in infants. This book provides the most current scientific information on milk proteins, from structure to biological properties. It will be of great benefit for those interested in milk production, milk chemistry, and human health.

This book was released on 2020 with total page 172 pages. Available in PDF, EPUB and Kindle. Book excerpt: Not only lactoferrin is antibacterial, but a wider range of whey proteins its bacteriostatic activity, such as lactoperoxidase and immunoglobulins, as well as low abundant immune-active proteins. Different heat treatments can induce the denaturation of these proteins to a different degree, which could result in a gradual change of their bacteriostatic activity. The effect of different heat treatments on the proteome of whey proteins and their bacteriostatic activity were investigated in Chapter 4. Skim milk samples were heated at 65 °C, 70 °C, 75 °C, 80 °C, and 85 °C, for 30 minutes. Milk serum was isolated from the heat-treated skim milk and the bacteriostatic capacity of this milk serum was tested against Streptococcus thermophilus, Escherichia coli, Lactococcus lactis and Pseudomonas fluorescens. The bacteriostatic activity of milk serum negatively correlated with the intensity of heat treatment, which was also reflected in the reduced level of native antibacterial proteins. There is a slight decrease of bacteriostatic activity, which was associated with denaturation of low abundant immune-active proteins, such as complement C7, monocyte differentiation antigen CD 14 and polymeric immunoglobulin receptor. There is a significant difference between milk samples treated for 30 minutes at
