This book was released on 2016 with total page 157 pages. Available in PDF, EPUB and Kindle. Book excerpt: Several countries around the world are facing the challenge of producing food with limited water resources for a growing population. This reality is forcing all sectors involved in the food supply chain to look for water conservation strategies that contribute to assure global food security. Besides water consumption, the food industry has to deal with wastewater generation; therefore, water reconditioning and reuse is an attractive solution to address both issues. The goal of this research was to demonstrate that high quality water can be recovered from whey, a by-product of the cheese making process, and reused in cleaning-in place (CIP) operations. Technical, economic, safety and environmental feasibility of the proposed intervention was also considered. First, the performance of the water recovery system was evaluated as well as the quality of protein, lactose and water recovered from whey. A combination of ultrafiltration and reverse osmosis allowed a water recovery of 47 % with > 98 % removal of the initial pollutants present in whey. Once spray dried, protein and lactose powder fulfill commercial standards. When applied in CIP systems, the cleaning efficiency of the recovered water was proven to be similar to tap water. Subsequently, a cost analysis was performed for small, medium and high cheese production scales; results demonstrated that the proposed intervention is economically feasible generating revenues of 0.18, 3.05 and 33.4 million $/year, respectively. Then, a comparative life cycle assessment was conducted, revealing that the recovery system generate 87.7 % and 18% lower environmental impacts than a wastewater and water production system, respectively. Energy usage was the input causing most of the emissions. Lastly, the risk assessment on the reuse of contaminated-reconditioned water with L. monocytogenes in fluid milk processing, indicated low levels of bacteria transferred from the contaminated water to the equipment surface.

This book was released on 2023-02-10 with total page 204 pages. Available in PDF, EPUB and Kindle. Book excerpt: Water is used for a wide range of activities in the dairy sector, which consumes a substantial volume of first-use drinking water for production processes, cleaning and disinfection. There is a great potential to exploit possible sources of reusable water in the dairy sector. In 2020, the 43rd session of the Codex Alimentarius Commission approved the new work entitled ¡°Development of Guidelines for the Safe Use and Reuse of Water in Food Production¡± proposed by the 51st session of the Codex Committee on Food Hygiene. To support this work, the Joint FAO/WHO Expert Meeting on Microbiological Risk Assessment (JEMRA) was asked to provide scientific advice regarding safe use and reuse of water in the dairy sector. JEMRA convened an online meeting from 14 June to 2 July 2021 to provide clear and practical guidance on risk-based approaches to assess and manage fit-for-purpose water sourcing, use and reuse in the dairy sector. This report describes the output of this meeting to support the decision-making when applying the concept of fit-for-purpose water for use in the production and processing of dairy products.

This book was released on 2020-11-26 with total page 210 pages. Available in PDF, EPUB and Kindle. Book excerpt: Intensifying water constraints threaten food security and nutrition. Thus, urgent action is needed to make water use in agriculture more sustainable and equitable. Irrigated agriculture remains by far the largest user of freshwater, but scarcity of freshwater is a growing problem owing to increasing demand and competition for freshwater resources. At the same time, rainfed agriculture is facing increasing precipitation variability driven by climate change. These trends will exacerbate disputes among water users and inequality in access to water, especially for small-scale farmers, the rural poor and other vulnerable populations. The State of Food and Agriculture 2020 presents new estimates on the pervasiveness of water scarcity in irrigated agriculture and of water shortages in rainfed agriculture, as well as on the number of people affected. It finds major differences across countries, and also substantial spatial variation within countries. This evidence informs a discussion of how countries may determine appropriate policies and interventions, depending on the nature and magnitude of the problem, but also on other factors such as the type of agricultural production system and countries’ level of development and their political structures. Based on this, the publication provides guidance on how countries can prioritize policies and interventions to overcome water constraints in agriculture, while ensuring efficient, sustainable and equitable access to water.

This book was released on 2012-12-06 with total page 341 pages. Available in PDF, EPUB and Kindle. Book excerpt: Masters Theses in the Pure and Applied Sciences was first conceived, published, and disseminated by the Center for Information and Numerical Data Analysis and Synthesis (CINDAS)* at Purdue University in 1957, starting its coverage of theses with the academic year 1955. Beginning with Volume 13, the printing and dis semination phases of the activity were transferred to University Microfilms/Xerox of Ann Arbor, Michigan, with the thought that such an arrangement would be more beneficial to the academic and general scientific and technical community. After five years of this jOint undertaking we had concluded that it was in the interest of all concerned if the printing and distribution of the volumes were handled by an international publishing house to assure improved service and broader dissemination. Hence, starting with Volume 18, Masters Theses in the Pure and Applied Sciences has been disseminated on a worldwide basis by Plenum Publishing Corporation of New York, and in the same year the coverage was broadened to include Canadian universities. All back issues can also be ordered from Plenum. We have reported in Volume 40 (thesis year 1995) a total of 10,746 thesis titles from 19 Canadian and 144 United States universities. We are sure that this broader base for these titles reported will greatly enhance the value of this impor tant annual reference work. While Volume 40 reports theses submitted in 1995, on occasion, certain uni versities do report theses submitted in previous years but not reported at the time.
Download or read book Membrane Processing for Dairy Ingredient Separation written by Kang Hu and published by John Wiley & Sons. This book was released on 2015-07-20 with total page 293 pages. Available in PDF, EPUB and Kindle. Book excerpt: Membrane processing is a filtration technique in which particles are separated from liquids by being forced through a porous material, or membrane. Applied to dairy products, the separation techniques allow valuable compounds, found in milk, to be isolated for use as ingredients in food processing. A comprehensive overview of membrane separation processes, this book explores various applications such as pressure driven processes, electrical field driven processes, and concentration driven processes, for the recovery of various dairy streams and ingredients. The topics covered place emphasis on new applications, including microfiltration, ultrafiltration, reverse osmosis, electrodialysis, and pervaporation. The text also presents in-depth knowledge of the mechanisms of each membrane separation process, as well as membrane types and the equipment used in these processes. Combining their educational backgrounds and substantial industrial experience in dairy ingredients processes, the authors address cutting-edge technologies that have been thoroughly researched and have great potential to be commercialized in the near future. The book will therefore be of interest to dairy industry professionals and will serve as a source of reference material for professors and students in food science and engineering.

This book was released on 2007-03-31 with total page 683 pages. Available in PDF, EPUB and Kindle. Book excerpt: The intensification of agriculture and food production in recent years has led to an increase in the production of food co-products and wastes. Their disposal by incineration or landfill is often expensive as well as environmentally sensitive. Methods to valorise unused co-products and improve the management of wastes that cannot be reused, as well as techniques to reduce the quantity of waste produced in the first place, are increasingly important to the food industry. With its distinguished editor and array of international contributors, Waste management and co-product recovery in food processing reviews the latest developments in this area and describes how they can be used to reduce waste. The first section of the book provides a concise introduction to the field with a particular focus on legislation and consumer interests, principle drivers of waste management. Part two addresses the minimisation of biowaste and the optimisation of water and energy use in food processing. The third section covers key technologies for co-product separation and recovery, such as supercritical fluid extraction and membrane filtration, as well as important issues to consider when recovering co-products, such as waste stabilisation and microbiological risk assessment. Part four offers specific examples of waste management and co-product exploitation in particular sectors such as the red meat, poultry, dairy, fish and fruit and vegetable industries. The final part of the book summarises advanced techniques, to dispose of waste products that cannot be reused, and reviews state of the art technologies for wastewater treatment. Waste management and co-product recovery in food processing is a vital reference to all those in the food processing industry concerned with waste minimisation, co-product valorisation and end waste management. Looks at the optimisation of manufacturing procedures to decrease waste, energy and water use Explores methods to valorise waste by co-product recovery Considers best practice in different sectors of the food industry
