Download or read book Fungi and Food Spoilage written by John I. Pitt and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 599 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is designed as a laboratory guide for the food microbiologist, to assist in the isolation and identification of common food-borne fungi. We emphasise the fungi which cause food spoilage, but also devote space to the fungi commonly encountered in foods at harvest, and in the food factory. As far as possible, we have kept the text simple, although the need for clarity in the descriptions has necessitated the use of some specialised mycological terms. The identification keys have been designed for use by microbiologists with little or no prior knowledge of mycology. For identification to genus level, they are based primarily on the cultural and physiological characteristics of fungi grown under a standardised set of conditions. The microscopic features of the various fungi become more important when identifying isolates at the species level. Nearly all of the species treated have been illustrated with colony photographs, together with photomicrographs or line drawings. The photomicrographs were taken using a Zeiss WL microscope fitted with Nomarski interference contrast optics. We are indebted to Mr W. Rushton and Ms L. Burton, who printed the many hundreds of photographs used to make up the figures in this book. We also wish to express out appreciation to Dr D.L. Hawksworth, Dr A.H.S.

Download or read book Compendium of the Microbiological Spoilage of Foods and Beverages written by Michael P. Doyle and published by Springer Science & Business Media. This book was released on 2009-09-23 with total page 376 pages. Available in PDF, EPUB and Kindle. Book excerpt: The increased emphasis on food safety during the past two decades has decreased the emphasis on the loss of food through spoilage, particularly in developed co- tries where food is more abundant. In these countries spoilage is a commercial issue that affects the pro?t or loss of producers and manufacturers. In lesser developed countries spoilage continues to be a major concern. The amount of food lost to spoilage is not known. As will be evident in this text, stability and the type of spoilage are in?uenced by the inherent properties of the food and many other factors. During the Second World War a major effort was given to developing the te- nologies needed to ship foods to different regions of the world without spoilage. The food was essential to the military and to populations in countries that could not provide for themselves. Since then, progress has been made in improved product formulations, processing, packaging, and distribution systems. New products have continued to evolve, but for many new perishable foods product stability continues to be a limiting factor. Many new products have failed to reach the marketplace because of spoilage issues.

Download or read book Yeasts in Food and Beverages written by Amparo Querol and published by Springer Science & Business Media. This book was released on 2006-12-30 with total page 457 pages. Available in PDF, EPUB and Kindle. Book excerpt: As a group of microorganisms, yeasts have an enormous impact on food and bev- age production. Scientific and technological understanding of their roles in this p- duction began to emerge in the mid-1800s, starting with the pioneering studies of Pasteur in France and Hansen in Denmark on the microbiology of beer and wine fermentations. Since that time, researchers throughout the world have been engaged in a fascinating journey of discovery and development – learning about the great diversity of food and beverage commodities that are produced or impacted by yeast activity, about the diversity of yeast species associated with these activities, and about the diversity of biochemical, physiological and molecular mechanisms that underpin the many roles of yeasts in food and beverage production. Many excellent books have now been published on yeasts in food and beverage production, and it is reasonable to ask the question – why another book? There are two different approaches to describe and understand the role of yeasts in food and beverage production. One approach is to focus on the commodity and the technology of its processing (e. g. wine fermentation, fermentation of bakery products), and this is the direction that most books on food and beverage yeasts have taken, to date. A second approach is to focus on the yeasts, themselves, and their bi- ogy in the context of food and beverage habitats.

Download or read book Fungi and Food Spoilage written by John I. Pitt and published by Springer Science & Business Media. This book was released on 2009-07-25 with total page 524 pages. Available in PDF, EPUB and Kindle. Book excerpt: In contrast to the second edition, the third edition of ‘‘Fungi and Food Spoilage’’ is evolutionary rather than revolutionary. The second edition was intended to cover almost all of the species likely to be encountered in mainstream food supplies, and only a few additional species have been included in this new edition. The third edition represents primarily an updating – of taxonomy, physiology, mycotoxin production and ecology. Changes in taxonomy reflect the impact that molecular methods have had on our understanding of classification but, it must be said, have not radically altered the overall picture. The improvements in the understanding of the physiology of food spoilage fungi have been relatively small, reflecting perhaps the lack of emphasis on physiology in modern mic- biological science. Much remains to be understood about the specificity of particular fungi for particular substrates, of the influence of water activity on the growth of many of the species treated, and even on such basic parameters as cardinal temperatures for growth and the influence of pH and preservatives. Since 1997, a great deal has been learnt about the specificity of mycotoxin production and in which commodities and products-specific mycotoxins are likely to occur. Changes in our understanding of the ecology of the included species are also in most cases evolutionary. A great number of papers have been published on the ecology of foodborne fungi in the past few years, but with few exceptions the basic ecology of the included species remains.

Download or read book Food Safety and Quality Based Shelf Life of Perishable Foods written by Peter J. Taormina and published by Springer Nature. This book was released on 2021 with total page 167 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book addresses the shelf life of foods, a key factor in determining how food is distributed and consequently where and when different food products are available for consumption. Shelf life is determined by several factors, including microbiological, chemical, physical, and organoleptic deterioration. Often these factors are interrelated and interdependent. The editors of this volume focus specifically on the microbial factors related to shelf life of perishable foods and food commodities. This allows for more detailed coverage of foodborne bacterial pathogens and spoilage microorganisms of concern. The initial part of the book covers the why and how of shelf life determination as well as the specific microbial pathogens and spoilage microorganisms of concern for perishable foods. Contributors address topics such as the techniques utilized for determination of shelf life, the frequency of shelf life testing for different products, the interpretation of data to make shelf life determinations, and management of shelf life of food products from the perspective of the food producer, distributor, retailer, and regulator. Three key areas impacting shelf life are addressed in detail: sanitation, processing, and packaging. The sanitation chapter explains the necessary components of cleaning and sanitizing to assure a hygienic processing environment and why that is critical to shelf life control. Traditional processing procedures are reviewed and advanced processing technologies are explored. Materials used in food packaging and the utilization of traditional and activated food packaging by product type are covered in detail. The latter two chapters of the book delve into newer techniques of analysis and explore the microbiome of food products. Implications of microbial ecology and microbial quantification in food products are discussed in chapters on genomics and in the changing dogma of meat shelf life. The primary audience for this work includes food industry quality and food safety technicians, managers, directors, and executives responsible for shelf life. Academicians and governmental researchers involved in research and teaching about food safety and quality will also find the material relevant and useful.
