Improving Quality
edited by Philip Richardson

In-Pack Processed Foods addresses recent developments which have enabled the production of in-pack processed foods with improved sensory quality as well as new types of heat-preserved products packaged in innovative containers. It covers advances in packaging formats and processing technologies and their application to produce higher quality, safer foods.

Features:

  • reviews advances in packaging formats and processing technologies
  • covers innovative can designs and non-traditional packaging formats
  • examines the safety of in-pack processed foods, including concerns over pathogens
  • concludes with chapters on improving quality on particular types of in-pack processed foods, such as fish
  • Part One covers innovative can designs and non-traditional packaging formats, such as retort pouches.

    Part Two reviews the developments in processing and process control technology required by newer types of packaging.

    Part Three addresses the safety of in-pack processed foods, including concerns over pathogens and hazardous compounds in processed foods.

    Part Four contains chapters on novel methods to optimise the quality of particular types of in-pack processed foods such as fruit and vegetables, meat, poultry and fish products.
