Allergens in food and their detection, management and elimination constitute a key issue for food manufacturers, especially in terms of safety. This book reviews current and emerging technologies for detecting and reducing allergens, as well as issues such as traceability, regulation and consumer attitudes. Following an introductory chapter by a distinguished expert, part one covers allergen management throughout the food chain. Part two details current and emerging methods of allergen detection in food, and part three covers methods for reducing and eliminating allergens in food. Finally, part four focuses on the control and detection of individual food allergens and the risks each one presents in food manufacture.

Simon Flanagan Reading Scientific Services Ltd (RSSL), UK. Simon Flanagan, Head of Specialty Analysis & Food Allergen Services at Reading Scientific Services Ltd (RSSL), Reading, LA. Simon is an internationally acclaimed Technical Consultant specializing in the field of food allergens. He is a biochemist by training and gained experience of working in a variety of sectors within the food industry before joining RSSL in 2002. Simon has worked with global blue chip manufacturers, retailers and ingredient suppliers, as well as manufacturers of specialist dietary products.Simon has been involved in a broad scope of projects, from futureproofing corporate allergen policy through to independent expert site risk assessment and training programs. Simon is affiliated with numerous professional bodies, industry groups and technical committees and has?published several articles in peer reviewed journals. He was presented with a technical leadership award in 2014 for contributions to food safety and a SOFHT industry award for the development of RSSL's practical allergen workshops. He was also awarded 'Food and Drink Scientist of the Year'?at the FDF awards in 2018.
Simon was the first to develop a methodology for quantitative allergen risk assessment, which is becoming widely accepted as industry best practice. This methodology was adopted by Food and Drink Europe in their 2013 allergen management standard.? This approach to risk assessment is the foundation of RSSL's allergen consultancy service and?training courses. In recognition of this work, in 2019 he was awarded a Global Qudos Award by Mondelez International.
Simon is a fully qualified HACCP practitioner and lead auditor & experienced trainer who has developed a number of factory workshops and food safety training programmes for chemical and allergen hazards
