What are the problems?
• Regions of the world were a high percentage
of the population is food insecure
• High cost of animal source protein
• Poor or lack of cold chain in developing
countries
2
What are the opportunities?
• Thermal processing, using microwave energy, is
a technology that is rapidly being adopted
within the food industry
• U.S. pork demand is high world wide
Potential to add tremendous value to pork
based by-products
• NCSU FBNS is a source of innovation

Why
South Africa?
4
• Regions in Sub-Saharan Africa maintain
populations where food resources are
insecure
• Protein consumption in Sub-Saharan Africa
only 0-20 g of animal protein each day,
compared to 73g per day in the U.S.

Project Objectives
• Develop formulations customized for export to
countries of South Africa, Asia and Latin America
• Measure the dielectric properties of pork variety
meats to be used in the formulations.
12
Project Objectives
• Develop and implement the preliminary processing
sequence to targeted products
• Generate sample products for initial testing
