Mastication is chewing. When you chew your food, its being masticated by your teeth. Its grinding down and breaking the food up as part of the digestive process.
So what is a masticating juicer? A masticating juicer is a juicer that follows the same core principle of grinding the produce down and pressing it.
But there is a bit of controversy on what deserves to be called a masticating juicer. For example there are three main types of juicers claiming to be masticating juicers in todays market. One is the twin gear juicer like from Green Star, the other is a slow auger juice like from Omega, and the third is the traditional Champion juicer style auger with metal teeth. Originally only Champion juicers claimed to be masticating juicers while the others designated themselves as single auger juicers and twin-gear juicers. In recent years the term “masticating” has been generalized and even adopted in most mainstream marketing such as Omegas Masticating juicers which are single auger slow juicers.
The confusion comes in when talking about speeds. Centrifugal juicers are often judged on the fact that they run at high RPMs and cause juice to heat and oxidize. While this is a proven point, most people don’t realize that not all masticating juicers are slow juicers such as in the case with Champion juicers which run at 1725 RPM. All other single auger and twin gear juicers are 80-160 RPM.
Here is a highlight of the differences between each type of masticating juicers.
Champion style masticating: This is the way champion juicers have been juicing since the 50s. Basically its like a single auger juicer except it has metal blades, is not a solid auger, and runs at a 1725RPM.
A twin gear juicer uses two very thick, small gears (like screws) together to squeeze through produce and press the juice. This is widely considered to be the over all best type of masticating juicer due to its low oxidation, high yield, and low heat. But it is also generally more expensive than single auger or centrifugal juicers.
A single auger juicer basically uses a thick plastic screw and presses the produce through a hole, squeezing out the juice. These are always slow juicers never running at more than 160RPM, usually at 80RPM.
So can we say that an Omega single auger juicer is masticating when the term was originally used to description a product closer to a horizontal centrifugal juicer (the Champion)? Well Omega seems to think so and they are the ones paying to educate the customers on their product, and the general public has accepted this to be the case. Therefor the term masticating juicer will continue to include the Champion juicer, single auger juicers, and twin-gear juicers as its more to do with the style of breaking down produce vs the speed in which its broken down.
