Moderator Dr. Rebecca Milczarek (USDA-ARS) will provide an introduction to conventional freezing technologies and explain the shortcomings of currently-available approaches to freezing. Speakers will then describe their novel freezing technologies. Dr. Soojin Jun (University of Hawaii at Manoa) will describe how the use of pulsed electric and magnetic fields forms the foundation for a supercooling technology that preserves perishable materials at below-freezing temperatures without the formation of ice crystals. Dr. Matthew Powell-Palm (University of California – Berkeley) and Dr. Cristina Bilbao-Sainz (USDA-ARS) will discuss investigations of isochoric (constant-volume) freezing for cryopreservation of organs for transplant (without inducing the formation of deleterious ice crystals in the tissue) and how they are translating this process from medicine to food via collaboration with USDA-ARS.
Goals:
-Attendees will be able to recognize the fundamental limitations of current freezing technologies, which can impart degradation of food texture, flavor, and nutrition.
-Attendees will learn the principles of electromagnetic field-assisted freezing.
-Attendees will learn the principles of isochoric freezing.
-Attendees will gain an appreciation for how the two novel freezing technologies can address the shortcomings of current freezing technologies.
All IFT webcasts are free for IFT Premier and Student members.
