Download or read book UHT Milk Spoilage and the Influence of Fat Content written by Maciej Nodzyński and published by GRIN Verlag. This book was released on 2021-08-26 with total page 13 pages. Available in PDF, EPUB and Kindle. Book excerpt: Academic Paper from the year 2021 in the subject Biology - Micro- and Molecular Biology, grade: 6 (IB), , course: IB Diploma Programme, language: English, abstract: This paper aims to explore the changes in the pH of milk and the process of creaming that taken together represent the dependent variable, that is UHT milk spoilage. Most importantly, the connection between fat content and the dependent variable will be investigated. The research suggests that the rate of UHT milk spoilage increases with the amount of fat present in the milk, and this investigation will assess the validity of this statement. The importance of this subject is significant because UHT milk consumption constantly increases, reaching the threshold of 119 million tons in 2019 and constitutes a strong fundament of people’s diet. The research extends the knowledge about the process of UHT milk spoilage and its link with fat content as well as gives food for thought when it comes to the UHT milk preservation methods, shelf life, and the impact of other ingredients on the process of spoilage.

Download or read book High Temperature Processing of Milk and Milk Products written by Hilton C. Deeth and published by John Wiley & Sons. This book was released on 2017-05-08 with total page 600 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book covers many aspects of thermal processing of milk and milk products with particular focus on UHT processing. It commences with an overview of the major thermal processing technologies: thermisation, pasteurisation, extended-shelf-life (ESL), UHT and in-container sterilisation. It discusses the principles of the technologies, the processing and packaging equipment used, processing issues such as temperature-time profiles, heat stability, fouling and cleaning, and the quality and safety aspects of the products produced. It provides a balance of the engineering aspects of the processes and the chemical, microbiological and sensory aspects of the products. The changes that occur in products during processing and storage, and the related defects which can arise, are central to the book. The discussions of these changes will be an aid to industry personnel in identifying the causes of quality defects in these products and devising measures which can be taken to eliminate or minimise the defects.
Download or read book Effects of Raw Milk Quality on UHT Milk Instability written by and published by . This book was released on 2019 with total page 174 pages. Available in PDF, EPUB and Kindle. Book excerpt: The demand for ultra-high-temperature (UHT) processed milk is increasing worldwide. Meanwhile, the problem of destabilization during its shelf life, with age gelation and fat destabilization being the most prominent defects, is still a major factor that limits shelf life and commercial exploitation. Previous studies have revealed that the main factor of UHT milk destabilization is protein enzymatic hydrolysis. The two main categories of residual proteases in UHT milk are the native protease plasmin and heat resistant bacterial proteases, both of which are closely related with the raw milk quality. However, a complete overview of how the proteases destabilize casein micelles and fat globules in UHT milk is still lacking. Hence, this thesis explored the enzymatic factors associated with destabilization of UHT milk, aiming to provide new insights into the mechanisms of UHT milk instability and to determine the significance of raw milk quality control in UHT milk production.

Download or read book Climate Smart Food written by Dave Reay and published by Springer. This book was released on 2019-01-01 with total page 201 pages. Available in PDF, EPUB and Kindle. Book excerpt: This open access book asks just how climate-smart our food really is. It follows an average day's worth of food and drink to see where it comes from, how far it travels, and the carbon price we all pay for it. From our breakfast tea and toast, through breaktime chocolate bar, to take-away supper, Dave Reay explores the weather extremes the worlds farmers are already dealing with, and what new threats climate change will bring. Readers will encounter heat waves and hurricanes, wildfires and deadly toxins, as well as some truly climate-smart solutions. In every case there are responses that could cut emissions while boosting resilience and livelihoods. Ultimately we are all in this together, our decisions on what food we buy and how we consume it send life-changing ripples right through the global web that is our food supply. As we face a future of 10 billion mouths to feed in a rapidly changing climate, its time to get to know our farmers and herders, our vintners and fisherfolk, a whole lot better. Dave Reay is Professor of Carbon Management at the University of Edinburgh, UK. He has studied climate change for over 20 years, from warming impacts in the Southern Ocean, through carbon fluxes in forests, to greenhouse gas emissions from wetlands and agriculture. In 2018 he received the Chancellors Award for Teaching for his work in climate change education. His latest project involves managing a large area of coastal land in Scotland to regrow native tree species and trap a lifetimes carbon.
Download or read book Lipids in Health and Disease written by Peter Quinn and published by Springer Science & Business Media. This book was released on 2008-08-27 with total page 603 pages. Available in PDF, EPUB and Kindle. Book excerpt: Lipids are functionally versatile molecules. They have evolved from relatively simple hydrocarbons that serve as depot storages of metabolites and barriers to the permeation of solutes into complex compounds that perform a variety of signalling functions in higher organisms. This volume is devoted to the polar lipids and their constituents. We have omitted the neutral lipids like fats and oils because their function is generally to act as deposits of metabolizable substrates. The sterols are also outside the scope of the present volume and the reader is referred to volume 28 of this series which is the subject of cholesterol. The polar lipids are comprised of fatty acids attached to either glycerol or sphingosine. The fatty acids themselves constitute an important reservoir of substrates for conversion into families of signalling and modulating molecules including the eicosanoids amongst which are the prostaglandins, thromboxanes and leucotrienes. The way fatty acid metabolism is regulated in the liver and how fatty acids are desaturated are subjects considered in the first part of this volume. This section also deals with the modulation of protein function and inflammation by unsaturated fatty acids and their derivatives. New insights into the role of fatty acid synthesis and eicosenoid function in tumour progression and metastasis are presented.
Download or read book Milk and Milk Products written by Alan H. Varnam and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 461 pages. Available in PDF, EPUB and Kindle. Book excerpt: Milk has been an important food for man since the domestication of cattle and the adoption of a pastoralist agriculture. It is also the most versatile of the animal-derived food commodities and is a component of the diet in many physical forms. In addition to milk itself, a rural technology evolved which permitted the manufacture of cheese, fer mented milks, cream and butter. At a later date, successive advances in technology were exploited in the manufacture of ice cream, concen trated and dried milks and, at a later date, of ultra-heat-treated dairy products, new dairy desserts and new functional products. At the same time, however, dairy products have been increasingly perceived as unhealthy foods and a number of high quality dairy substitutes, or analogues, have been developed which have made significant inroads into the total dairy food market. Paradoxically, perhaps, the technology which, on the one hand, presents a threat to the dairy industry through making possible high quality substitutes offers, on the other hand, an opportunity to exploit new uses for milk and its components and to develop entirely new dairy products. Further, the development of products such as low fat dairy spreads has tended to blur the distinction between the dairy industry and its imitators and further broadened the range of knowledge required of dairy scientists and technologists.
