Share Article

Napasol’s largest nut pasteurization unit in the US goes into operation at Hazelnut Growers of Oregon (HGO) in Cornelius, Oregon. In the Napasol process products are treated at relatively low temperatures with dry saturated steam, thus maintaining the sensory attributes of raw nuts while achieving a minimum 5log reduction in pathogens.

Napasol AG is a Swiss company that sells equipment for the pasteurization of nuts, seeds, spices, herbs, botanicals and other dry ingredients. Napasol is establishing itself as the preferred technology for pasteurizing almonds, walnuts, pistachios, cashews, macadamias, Brazil nuts, pine nuts and hazelnuts with several large plants in the US and Europe. Its growing success is due to the superior performance of its saturated steam batch process and the flexible technical solutions it brings to the industry. Each installation is custom built to fit into the customer’s facility and units can be sized for throughputs ranging from 400 lbs/hr to 30’000 lbs/hr.

The Hazelnut Growers of Oregon installation has a throughput of over 10’000 lbs/ hour. The 30 million lbs of hazelnuts in-shell and kernels that the cooperative handles can easily be treated in this Napasol pasteurizer with plenty of spare capacity for growth. For the Oregon cooperative bringing food safety in house will give an excellent return on investment because of the low operating cost of the Napasol plant and savings on shipment and treatment cost for third party toll services. The saturated steam treatment offers the additional advantage of being natural, a more appropriate process for a raw product touted for its health and nutritional benefits.

“As the Peanut and Tree Nut Processor Association Convention opens this week in San Diego, issues regarding food safety will be discussed in light of a pending FDA Risk Assessment on tree nuts and the implementation of the Food Safety Modernization Act in the nut industry “says Dr. Cameon Ivarsson Scientific Director of Napasol, adding “Pathogens such as Salmonella have been involved in food borne illnesses and product recalls in several kinds of nuts including Hazelnuts”.

Napasol AG is a Swiss company that sells equipment for the pasteurization of low moisture foods such as nuts, seeds, spices, herbs, botanicals and other dry ingredients. It is active worldwide through Napasol North America in Fargo, North Dakota, Napasol Asia in Honk Kong and Napasol AG in Switzerland. Testing facilities are available in the US and Europe for trials and application development.
