Frontier Natural Products Co-op™ becomes the first U.S. manufacturer to commission a Napasol® steam pasteurization plant
New process ensures food safety while maintaining aroma and flavor attributes

Norway, Iowa (February 9, 2010) — With the commissioning of the first Napasol Pasteurization Unit in the United States, Frontier Natural Products Co-op, a leader in the natural and organic herb, spice, and tea industry, extends its leadership position through food safety innovation. Most current sterilization methods, including ethylene oxide (ETO) fumigation and irradiation, cannot be used on organic products. Many steam sterilization systems previously installed in the United States are marginally effective or can affect the flavor and aroma attributes significantly.

The Napasol process uses a highly controlled program of steam injection and vacuum that is optimized for each product, insuring the highest microbiological safety by eliminating pathogens while maintaining flavor and aroma profiles in an organic and natural process. This new process also eliminates allergen cross-contamination, which is a risk in some steam sterilization systems.

Herbs and spices are sourced globally and are considered high risk products as microbial contamination may occur in the field, or during storage and processing. Although dry foods do not support microbial growth, they may still harbor pathogenic bacteria which even in small numbers can be harmful if they are used in foods which do not undergo high temperature sterilization. Sampling and microbiological testing may not be sufficient to eliminate all microbiological risks, and the industry has been affected by several major product recalls in recent years, including: peppercorns, basil, sage, paprika, cumin, and oregano (1).

Frontier has a very robust and effective quality assurance system that spans its entire supply chain and is committed to the highest levels of Good Manufacturing Practices, while continually investing in higher food safety programs. Frontier also maintains the highest AIB-rating of Superior on its third-party food safety and quality audits.

“We are very pleased to be the first manufacturer in the United States to have made the investment in Napasol’s steam sterilization technology since it allows us to offer the safest herbs and spices to our customers without the use of chemicals or irradiation,” states Dr. Ravin Donald, Frontier’s Vice President of Technical Services. He adds, “By using this new system, the herbs and spices are minimally exposed to steam, thereby maintaining the flavor profiles that consumers expect from the highest quality herbs and spices.”
