The earlier juicer models used centrifuge spinningsystem and fast chopping for Rose Paper extracting the juice. The current masticatingjuicers gradually crush the food similarly how teeth chews the food. Theprocessed food is basically chewed at first, then squeezed and pressed to getall available juice from the pulp. One of the main benefits of having a crushing,pressing masticating juicer is that it can juice even such tough and leafyvegetables as spinach and beet greens. A centrifugal juicer is just not capableof extracting a large amount of juice from such vegetables. A masticatingjuicer can offer you that high quality and vitamin rich juice that is found inleafy and fibrous vegetables. While juice prepared with a centrifugal juicer is still a deliciousand vitamin-rich drink compared to bottled, conserved fruit drinks, thehigh-speed extraction will get more oxygen into the juice resulting in theoxidation of vitamins and enzymes and accelerating the degradation process of thejuice.
Oxidation of the nutrients contained in the fruits and vegetable cellsreduces the nutrient value and health benefits of the juice made with a centrifugaljuice extractor. Compared to centrifugal juicers, the masticatingjuicers have a much slower rotation, limiting the amount of foam found in thejuice. Lower friction also results in less heat and thus vitamins and othervital nutrients are not destroyed. However, some patience is required becauseof the lower speed of the juicer. It takes longer to obtain the juice withmasticating juicers, but the juice is much better and healthier. Masticating juicers are excellent when it comes toextracting juice from tough vegetables and fruits.  
These devices are great asthey can produce large amounts of juice from nearly any fruit or vegetable,making it a highly cost effective process. Furthermore, as the masticatingprocess is a slow one the juice will contain a low amount of oxygen which canalter the juice. Although a masticating juicer appears to be one of thebest available options, it also has certain disadvantages. These are mostsuited to produce a large amount of 35g super soft dishcloth wipes for kitchen juice at once and to be used later on. Asthe masticating process is a slow one, it is not really recommended when youonly want to squeeze only a glass of nutritious juice.
