Steve James

Steve James The Founder and Director of the Food Refrigeration and Process Engineering Research Centre (FRPERC). Steve joined the Meat Research Institute (MRI) at Langford in September 1967. Over the past 42 years, he has carried out research into all aspects of food refrigeration ranging from primary chilling to domestic handling. He has also been active in the thermal processing of food including cooking and surface decontamination studies.

Since 1972 he has been at the forefront of computer modeling of heating and cooling processes in food processing. He is the author, or co-author, of over 400 publications, including the co-authorship of the book Meat Refrigeration. He routinely carries out industrial consultancies in all aspects of food processing, including expert witness work.

LEARN MORE ABOUT STEVE JAMES

Although I have qualifications in Mathematics, Physics and Mechanical Engineering I consider myself a Food Engineer after 36 years of working in the area.

My main areas of research interest are:

  • Food Refrigeration – Primary Chilling to Domestic Handling
  • Food Cooking – Industrial, Commercial and Domestic
  • Food Decontamination
  • Modelling of Food Cooking, Cooling, Freezing and Thawing
  • Meat Thawing
  • Thermal Processing of Food

I also have extensive experience of directly helping industry in the:

  • Specification, design, development and optimisation of food refrigeration, cooking and decontamination processes.
  • Trouble shooting of problems in food refrigeration and cooking systems.
  • Provision of arbitration and legal expert advise.
  • Provision of bespoke training.

My primary work passions are to:

  1. Get industry to specify and purchase refrigeration systems that actually achieve the real requirements of the process being carried out.
  2. Understand bacterial death kinetics so that I can model the effect of thermal decontamination processes.
  3. Accurately model changes in yield and dimensions during food cooking.
