Food processing is the step of the food chain that principally affects a food's physical or biochemical properties, along with determining the safety and shelf life of the product.  This book provides a comprehensive overview of innovations in non-thermal technologies specifically for fluid foods, recognized for their high bioavailability of macronutrients and micronutrients.

Considerable resources and expertise has been devoted to the processing of safe and wholesome foods.  Non-thermal technologies have been developed as an alternative to thermal processing, while still meeting required safety or shelf-life demands and minimising the effects on its nutritional and quality attributes.

Key Features

  • Examines non-thermal processing techniques specifically applied to fluid foods
  • Includes methods for mathematically evaluating each technique
  • Addresses global regulatory requirements for fluid foods
  • Provides recommendations and opportunities for various safety-related issues


Professionals in food processing research, quality assurance/control, product development. Also professionals involved with technical services and regulatory affairs in food processing
