Download or read book Measurement of Casein Micelle Size in Raw Dairy Cattle Milk by Dynamic Light Scattering written by Peter Hristov and published by . This book was released on 2016 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The particle size of milk influences its microstructure and defines the qualities of dairy products, such as colloidal stability and texture. Moreover, differences in casein micelle size may affect milk processing, especially cheese making. Hence, the size of casein micelle is an important characteristic of raw milk and determines the yield of dairy products. The aim of the present research is to estimate the casein micelle size in the raw milk of dairy cattle by dynamic light scattering. The obtained results may be used for genetic elaboration of the breed, as well as to increase the competitiveness of the milk industry by selection of animals with higher casein micelle size.
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.
Book Synopsis Casein Micelles and Their Properties by : Maneesha S. Mohan
Download or read book Casein Micelles and Their Properties written by Maneesha S. Mohan and published by . This book was released on 2014 with total page 250 pages. Available in PDF, EPUB and Kindle. Book excerpt: The internal structure of casein micelles is not fully understood. In the present work, we explore some of the basic questions about casein micelles in bovine milk including its size distribution, native binding properties and effect of ultra-high pressure homogenization (ultra-HPH) on technological properties of casein micelles. The size distribution of casein micelles was studied by cryo-TEM using skim milk from four cows. The degree of variation in casein micelle sizes (polydispersity) ranged between 0.39 and 0.47 for a size distribution ranging from 10 to 693 nm. These results indicated high polydispersity of casein micelles in milk from single cows. Casein micelles associated with vitamin A in four pasteurized skim milks (1.6 - 2.5 micro gm/mL of milk; 14 - 40% of the initial quantity detected in milks), while other protein fractions contained negligible vitamin A. Thus, casein micelles can inherently associate with hydrophobic probes like vitamin A in milk. This association of vitamin A to casein micelles in milk provided protection from degradation on exposure to ultraviolet light when compared to apple juice. Further, the effect of ultra-HPH up to 500 MPa on the physicochemical (apparent casein micelle size by dynamic light scattering) and technological characteristics (rennet coagulation - firmness [ 90 min, 1Hz, 0.01% strain]; acid gelation using 3%w/v glucono delta lactone – firmness [22°C, 110 min, 1Hz, 0.01% strain], SDS-PAGE) of casein micelles were studied. Casein micelle size increased from ca. 180 nm at 100 MPa to ca. 280 nm at 500 MPa HPH pressure. With increase in HPH pressure, renneting ability decreased until no coagulation was obtained for 500 MPa HPH milk. The firmness of HPH milk acid gels increased from about 76 Pa to 108 Pa when pressure was increased above 100 MPa (up to 400 MPa) HPH as compared to acid gels made from non-homogenized milk. Overall we elucidated the size distribution, binding ability to vitamin A and changes occurring on ultra-HPH in casein micelles. This information can be utilized by the industry to modify and utilize casein micelles as an ingredient for different end uses.
Download or read book Best Before written by Nicola Temple and published by Bloomsbury Publishing. This book was released on 2018-02-22 with total page 273 pages. Available in PDF, EPUB and Kindle. Book excerpt: The whole story behind what's in the food on our plate. Long before there was the ready meal, humans processed food to preserve it and make it safe. From fire to fermentation, our ancestors survived periods of famine by changing the very nature of their food. This ability to process food has undoubtedly made us one of the most successful species on the planet, but have we gone too far? Through manipulating chemical reactions and organisms, scientists have unlocked methods of improving food longevity and increasing supply, from apples that stay fresh for weeks to cheese that is matured over days rather than months. And more obscure types of food processing, such as growing steaks in a test-tube and 3D-printed pizzas, seem to have come straight from the pages of a science-fiction novel. These developments are keeping up with the changing needs of the demanding consumer, but we only notice them when the latest scaremongering headline hits the news. Best Before puts processed food into perspective. It explores how processing methods have evolved in many of the foods that we love in response to big business, consumer demand, health concerns, innovation, political will, waste and even war. Best Before arms readers with the information they need to be rational consumers, capable of making informed decisions about their food.

Download or read book Effect of Milk Fat Globule Size on the Physical Functionality of Dairy Products written by Tuyen Truong and published by Springer. This book was released on 2015-12-11 with total page 75 pages. Available in PDF, EPUB and Kindle. Book excerpt: Effect of Milk Fat Globule Size on the Physical Functionality of Dairy Products provides a comprehensive overview of techniques utilized to vary milk fat globule size in fat-structured dairy products. The text aims to highlight the importance of both native and emulsified milk fat globule size in the processing and functionality of these products. Both herd managements strategies and fractionation techniques utilized to vary milk fat globule size are covered thoroughly, as are the effects of mechanical sheer processing. The influence of different size fat globules on aspects such as TAG composition, physical stability, viscosity, crystallization properties and electric conductivity are studied, as are the influences on processability and function. This Brief aims to highlight the importance of milk fat as a determinant of the microstructural, rheological and sensorial properties of fat-containing dairy products such as milk, cream, yogurt, ice cream, cheese, butter and milk chocolate. Since milk fat globules have a widely varied size distribution, controlling their size is of major importance in processing. In comprehensively covering the various methods used to vary milk fat globule size, this text serves as an important resource for those involved in dairy product processing.
Book Synopsis Handbook of Mineral Elements in Food by : Miguel de la Guardia
Download or read book Handbook of Mineral Elements in Food written by Miguel de la Guardia and published by John Wiley & Sons. This book was released on 2015-04-20 with total page 800 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mineral elements are found in foods and drink of all different types, from drinking water through to mothers’ milk. The search for mineral elements has shown that many trace and ultratrace-level elements presented in food are required for a healthy life. By identifying and analysing these elements, it is possible to evaluate them for their specific health-giving properties, and conversely, to isolate their less desirable properties with a view to reducing or removing them altogether from some foods. The analysis of mineral elements requires a number of different techniques – some methods may be suitable for one food type yet completely unsuited to another. The Handbook of Mineral Elements in Food is the first book to bring together the analytical techniques, the regulatory and legislative framework, and the widest possible range of food types into one comprehensive handbook for food scientists and technologists. Much of the book is based on the authors’ own data, most of which is previously unpublished, making the Handbook of Mineral Elements in Food a vital and up-to-the-minute reference for food scientists in industry and academia alike. Analytical chemists, nutritionists and food policy makers will also find it an invaluable resource. Showcasing contributions from international researchers, and constituting a major resource for our future understanding of the topic, the Handbook of Mineral Elements in Food is an essential reference and should be found wherever food science and technology are researched and taught.

Book Synopsis Emerging Dairy Processing Technologies by : Nivedita Datta
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.
