A cold press juicer, also known as a masticating juicer is one of the popular types on the market. It derives its name from the process (mastication) involved in juicing and also because there is no heat involved in juice formation.
Cold press juicers are preferred by many because they do not involve heat which means more of the nutrients and enzymes in the fruits and vegetables is retained. Here is a brief look at how masticating juicers work.
Juice pressing mechanism of cold press juicers
As aforementioned, cold press juicers use a process known as mastication to squeeze the juice out of fruits and vegetables. Unlike blenders and centrifugal juicers, a masticating juicer uses a screw auger that first squeezes then crushes the produce to separate juice from the flesh. This process prevents the heat buildup experienced when using blenders and blades.
By using screw auger, masticating juicers prevent air from being drawn into the juice as common of centrifugal juicers that use spinning blades. Oxidation results in shorter shelf life which is why juice from blenders can only last for 24 hours before they go bad. On the other hand, cold-pressed juice is good for about 72 hours.
While masticating juicers are ideal for cold pressing, they are not 100% cold press juicers. The mastication process used is notably different from that used in producing industry grade cold pressed juice. In industrial production of bottled cold press juice, the juicers use hydraulic pressers that push the produce against a fine mesh to squeeze out almost all the juice from the flesh.
Once this is done, the juice is bottled and stored in large chambers that are filled with water to create high pressure on pathogens. The result is fresh juice that can last several weeks (rather than days) before going bad.
Masticating juicers are slower than other alternatives and will take longer to produce juice as there are no spinning blades and violent movements. You will also be required to cut produce into smaller sizes for a more efficient process.
Why you should choose a cold press juicer
The benefits of using cold press masticating juicers are quite obvious and straightforward. The ability to retain more nutrients and possibility of storing your juice for longer hours are only base reasons for buying such juicers. However, there are more benefits.
Masticating juicers are usually more expensive than centrifugal juicers for a reason. They are simply better. They use less product to produce the same amount of juice and are quite versatile. Most masticating juicers can double up to make butter, pasta, sauces and rice cakes among other things.
A cold press juicer will result in a healthier juice that contains most of the nutrients and enzymes. However, this comes at the expense of longer juicing times and a higher price tag. When looking for a masticating juicer, it is important to carefully review existing options and make sure they have the right features to meet your needs. Not all offers are desirable and certainly, not all of them perform equally. These juicers are ideal if you are in no hurry to produce high-quality juice from your produce.
