MILLIS, MASS. — The new Macrowave ultra-series pasteurization systems apply a high frequency electric field to products to control pathogens, according to Radio Frequency, Co., Millis. Material is conveyed through a high frequency electrode array where alternating electrical energy causes the material to heat rapidly and uniformly. Nutritional values and functionality are preserved because the material is not exposed to elevated temperatures for a long time.

Radio Frequency Co. offers a line of systems for the bulk or bagged pasteurization and/or insect deinfestation of nut meats as well as various types of flour, grains, pasta, tobacco, fishmeal, xanthan gum, other food ingredients and finished products.
