Methods for the Mycological Examination of Food


Book Description

The desirability, indeed the necessity, for standardization of methods for the examination of foods for contaminant and spoilage mycoflora has been apparent for some time. The concept of a specialist workshop to address this problem was borne during conversations at the Gordon Research Conference on "Hicrobiological Safety of Foods" in Plymouth, New Hampshire, in July 1982. Discussions at that time resulted in an Organizing Committee of four, who became the Editors, and a unique format: all attendees would be expected to contribute and, in most cases, more than once; and papers in nearly all sessions would be presented as a set of data on a single topic, not as a complete research paper. Each session would be followed by general discussion, and then a panel would formulate recommendations for approval by a final plenary session. The idea for this format was derived from the famous "Kananaskis I" workshop on Hyphomycete taxonomy and terminology organized by Bryce Kendrick of the University of Waterloo, Ontario in 1969. Attendance would necessarily be limited to a small group of specialists in food mycology. The scope of the workshop developed from answers to questionnaires circulated to prospective participants. To generate new data which would allow valid comparisons to be drawn, intending participants were given a variety of topics as assignments and asked to bring information obtained to the workshop.




Handbook of Culture Media for Food Microbiology


Book Description

This is a completely revised edition, including new material, from 'Culture Media for Food Microbiology' by J.E.L. Corry et al., published in Progress in Industrial Microbiology, Volume 34, Second Impression 1999. Written by the Working Party on Culture Media, of the International Committee on Food Microbiology and Hygiene, this is a handy reference for microbiologists wanting to know which media to use for the detection of various groups of microbes in food, and how to check their performance. The first part comprises reviews, written by international experts, of the media designed to isolate the major groups of microbes important in food spoilage, food fermentations or food-borne disease. The history and rationale of the selective agents, and the indicator systems are considered, as well as the relative merits of the various media. The second part contains monographs on approximately 90 of the most useful media. The first edition of this book has been frequently quoted in standard methods, especially those published by the International Standards Organisation (ISO) and the European Standards Organisation (CEN), as well as in the manuals of companies manufacturing microbiological media. In this second edition, almost all of the reviews have been completely rewritten, and the remainder revised. Approximately twelve monographs have been added and a few deleted. This book will be useful to anyone working in laboratories examining food - industrial, contract, medical, academic or public analyst, as well as other microbiologists, working in the pharmaceutical, cosmetic and clinical (medical and veterinary) areas - particularly with respect to quality assurance of media and methods in relation to laboratory accreditation.




Advances in Food Mycology


Book Description

This book represents the Proceedings of the Fifth International Workshop on Food Mycology, which was held on the Danish island of Samsø from 15-19 October, 2003. This series of Workshops c- menced in Boston, USA, in July 1984, from which the proceedings were published as Methods for Mycological Examination of Food (edited by A. D. King et al. , published by Plenum Press, New York, 1986). The second Workshop was held in Baarn, the Netherlands, in August 1990, and the proceedings were published as Modern Methods in Food Mycology (edited by R. A. Samson et al. , and published by Elsevier, Amsterdam, 1992). The Third Workshop was held in Copenhagen, Denmark, in 1994 and the Fourth near Uppsala, Sweden, in 1998. The proceedings of those two workshops were p- lished as scientific papers in the International Journal of Food Microbiology. International Workshops on Food Mycology are held under the auspices of the International Commission on Food Mycology, a Commission under the Mycology Division of the International Union of Microbiological Societies. Details of this Commission are given in the final chapter of this book. This Fifth Workshop was organised by Ulf Thrane, Jens Frisvad, Per V. Nielsen and Birgitte Andersen from the Center for Microbial Biotechnology, Technical University of Denmark, Kgs. Lyngby, v vi Foreword Denmark.




Fungi and Food Spoilage


Book Description

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.

Yeasts in Food


Book Description

Yeasts play a crucial role in the sensory quality of a wide range of foods. They can also be a major cause of food spoilage. Maximising their benefits whilst minimising their detrimental effects requires a thorough understanding of their complex characteristics and how these can best be manipulated by food processors.Yeasts in food begins by describing the enormous range of yeasts together with methods for detection, identification and analysis. It then discusses spoilage yeasts, methods of control and stress responses to food preservation techniques. Against this background, the bulk of the book looks at the role of yeasts in particular types of food. There are chapters on dairy products, meat, fruit, bread, soft drinks, alcoholic beverages, soy products, chocolate and coffee. Each chapter describes the diversity of yeasts associated with each type of food, their beneficial and detrimental effects on food quality, methods of analysis and quality control.With its distinguished editors and international team of over 30 contributors, Yeasts in food is a standard reference for the food industry in maximising the contribution of yeasts to food quality. - Describes the enormous range of yeasts together with methods for detection, identification and analysis - Discusses spoilage yeasts, methods of control and stress responses to food preservation techniques - Examines the beneficial and detrimental effects of yeasts in particular types of food, including dairy products, meat, fruit, bread, soft drinks, alcoholic beverages, soy products, chocolate and coffee

Statistical Quality Control for the Food Industry


Book Description

Considering the ability of food processing companies to consistently manu facture safe foods with uniform quality over the past 20 or 30 years without these new tools and new systems, one might expect that quality control improvements would be marginal. On the other hand, these changes have already provided sub stantial opportunities for process and product improvement. This second edition is intended to update the basic concepts and discuss some of the new ones. Preface to the First Edition If an automobile tire leaks or an electric light switch fails, if we are short-changed at a department store or erroneously billed for phone calls not made, if a plane de parture is delayed due to a mechanical failure-these are rather ordinary annoy ances which we have come to accept as normal occurrences. Contrast this with failure of a food product. If foreign matter is found in a food, if a product is discolored or crushed, if illness or discomfort occurs when a food product is eaten-the consumer reacts with anger, fear, and sometimes mass hys teria. The offending product is often returned to the seller, or a disgruntled letter is written to the manufacturer. In an extreme case, an expensive law suit may be filed against the company. The reaction is almost as severe if the failure is a dif ficult-to-open package or a leaking container. There is no tolerance for failure of food products.
