This is by far the most important requirement because the easier a juicer is to use and clean up, the more often you will use it. None of the other criteria listed below matters if you don't use the juicer. The amount of juice extracted from the fruit or vegetable. It is important that you maximize the amount of juice extracted. TYPE - Centrifugal, Low Speed and High Speed Masticating and Hydraulic Press Juicers.
Centrifugal juicers introduce oxygen into the juice, creating oxidation.
Oxidation degrades nutrients not immediately but over time. To maximize the nutrients of the juice, we recommend you drink the juice as soon as you make it. Low speed masticating juicers produce a higher quality juice because they don't produce as much oxidation. High speed masticating juicers can be problematic if heat is generated. Heat will destroy nutrients on contact, unlike oxidation which occurs over time.
