Opis

Laboratory Methods in Food Microbiology describes a wide range of methods for use in the microbiological analysis of foods, including approaches to counting and detection procedures for microorganisms, identification of bacteria, yeasts and fungi, microbiological analysis for the main food commodity groups, and safety in the food microbiology laboratory. The book also discusses specific food poisoning outbreaks in the United States.

CONTENTS INCLUDE

• Comprehensive methods and advice on choosing appropriate techniques
• Discussion of internationally recognized standards
• Detection and enumeration of food-borne pathogenic and toxigenic microorganisms
• Detailed sections on analyses appropriate for the main food commodity groups
• Identification of bacteria, yeasts, and fungi isolated from foods
• Safety in the food microbiology laboratory
• Appendix of recipes for media and reagents

Recenzje

"...is very diverse in content; it is surprising to find so many microbiological topics covered in less than 600 pages." --FOOD AUSTRALIA
