Ben Zickel, CTO of Goji Research

The RF cooking revolution – An exclusive interview with the Microwave Journal

Boston, 2 February 2017

We are on the verge of a new cooking revolution – RF cooking opens the door for a world of possibilities.  Ben Zickel, CTO of Goji Research, discusses this new cooking technology and the changes it is set to bring to consumers and restaurateurs in an exclusive interview with the Microwave Journal. With a history dating back more than 50 years, the Microwave Journal, a leading source for information on RF and microwave technology, is the highest print circulation magazine in the industry.

"With this technology, we can cook in a fraction of the time necessary when using a conventional oven and improve cooking uniformity, which results in higher quality and healthier food preparation." - Ben Zickel, CTO of Goji Research

High-power solid-state RF amplifiers can generate high-power RF in a much more controlled manner than the magnetrons used in microwave ovens. The addition of real-time software and a closed-loop feedback mechanism enables optimization of the phase, frequency and amplitude of the signals generated and emitted into the oven cavity when heating food. “With this technology, we can cook in a fraction of the time necessary when using a conventional oven and improve cooking uniformity, which results in higher quality and healthier food preparation,” Ben explains. “Furthermore, digitally controlled power generation and feedback improve the system’s reliability.”

Goji’s closed-loop system architecture controls RF power generation and allows faster and more even cooking while improving the oven’s reliability.‍

The demand for high-quality healthy food, in addition to the increasingly reduced amount of time we have available to cook and clean up, is a key driver for innovation in this space. The many applications of Goji’s technology include fresh or frozen high-quality meals prepared at home or work, or entire family meals including protein, vegetables and starch prepared in the press of a single button. Restaurants can also benefit from this technology through improvements in back-of-house operations; for example, by using on-demand rapid thawing. “The technology is not constrained to ovens, however,” Ben adds. “For example, refrigerators will have rapid thaw drawers where frozen meat, poultry or fish can be defrosted in a fraction of the time required conventionally.”

While the first RF cooking products are expected to reach the market soon, the time needed for market education and production scale-up means that mass adoption is likely to  take several years. Many of the new generation ovens leveraging RF power are expected to offer other smart-appliance functionality, such as internet connectivity, voice activation and artificial intelligence. These smart appliances will also enable recipe sharing between community members, and allow food manufacturers to share optimal recipes for their own products or make recommendations based on user activity.

About RF Cooking

RF cooking utilizes a high power solid-state amplifier which, as part of a complete RF module, transmits radio wave energy into an object to heat it. Unlike the magnetron in a microwave oven, the digital RF module can accurately control the frequency, amplitude and phase of the radio-waves. When combined with Goji’s proprietary closed-feedback sensing algorithm, the RF module enables more uniform and consistent cooking results, while shortening and simplifying the cooking process.
