Which to Pick: Cold Press or Centrifugal Juicer
We all know that making your own juice at home is better than going to the store to buy juice laden with sugar and artificial substances. When you are making your own juice, you know exactly what you are consuming, and this is critically important to your health.
Fresh fruit and vegetable juice has really taken off in Australia, but did you know that there’s more than one way to extract the juice from fresh produce? Here at Vitality 4 Life, we believe in slower methods of juicing because we've personally experienced the benefits. But we will let you decide.
This guide compiles some general information about juicing, with a special focus on the benefits of cold press juicing.
A Brief History of Cold Press Juicing
The world’s first cold press juicer, the Norwalk, was invented in the 1930’s by none other than the granddaddy of cold press juicing, Dr. Norman W. Walker. The Norwalk uses the hydraulic press method to extract the juice and is still produced today. The next cold press juicer to be developed was in 1993; the original twin gear juicer by Greenpower followed by the Oscar horizontal single gear juicer. The most recent invention is the vertical cold press juicer which now has been further developed with a wider mouth to allow faster, easier juicing including whole apples.
Types of Juicers
The most common method of juicing is with a centrifugal juicer which uses a high speed rotating blade. The slower masticating juicer, such as the Champion 2000+ juicer, uses a combination of 2 flat blades and a fine sieve.
Then there’s the slowest of them all, the cold press juicer which uses 1 or 2 slow turning screws to crush or squeeze the fruit and vegetables.
Method of Extraction
- Centrifugal: High Speed Blades
- Masticating: 2 flat blades + fine sieve
- Cold Press: 1 or 2 slow turning screws
How Does RPM Affect Juice Quality?
It’s important to note there is more to finding excellence in a juicer than just by RPM (revolutions per minute); the absolute lowest RPM is not the hallmark of the best juicer in the slow juicers category when it comes to nutritional content or actual yield.
The Greenpower Hippocrates juicer, the highest performing juicer in a juicer comparison conducted by Choice in 2007, actually had the highest RPM of the cold press juicers in the test. We advise consumers to beware of claims stating the best cold press juicers can be defined solely via this measure of the lowest RPM.
In fact RPM alone will only ensure the juice is not heated in any way and has no impact in of itself on the extent to which the cellulose wall is sufficiently opened to extract maximum enzymes and nutrients. In a broad and general sense, juicers with extremely fast RPMs are likely to heat the juice as its being extracted, and this has the potential to cause the loss of nutrition and enzymes.
Maximising Nutrient & Living Enzyme Retention
“Let food be thy medicine and medicine be thy food.”
Consider why you want a juicer. Do you want to be able to juice fruits and vegetables quickly without spending a large amount on a single piece of equipment? A centrifugal juicer is likely to be the best option as they tend to retail at lower prices and work very well. However, if you have stricter requirements on living enzyme retention and you need your juice to retain the maximum level of nutrient possible, cold press juicers are likely to be more suitable than a centrifugal juicer.
There are several factors which need to come together to produce a quality juice with high yield and high levels of enzymes and nutrients. Torque is the measure of force which drives the cold pressing action and this combined with the slow turning speed and the precision of the actual extraction method will ultimately determine the quality of the resulting juice.
Our ethos is based on the findings of numerous independent studies which have found that masticating and cold press juicers retain living enzymes and produce more nutrients than their faster spinning cousins.
In 2007, Choice, the Australian consumer authority, tested this theory by sending a sample of carrot juice from every single juicer type to their lab.
They found that all the cold press juicers and masticating juicers had around double the calcium of the centrifugal juicers. One cold press machine, the Hippocrates juicer by Greenpower, produced well over double the alpha carotene and beta carotene levels of any other sample.
If you don’t plan to drink your juice straight away, masticating or cold press juicers may be the way to go. Choice stored apple juice samples from every juicer for 48 hours. Nearly all the centrifugal juices had started to deteriorate whereas cold pressed and masticated varieties still smelt fresh and looked good.
In the 1920s, Dr Max Gerson developed the Gerson Therapy which is still active today via his daughter, founder of the Gerson Institute. The Gerson Therapy, a natural treatment developed to activate the body’s innate ability to heal itself through an organic, vegetarian diet, raw juices, coffee enemas and natural supplements aims to treat the underlying causes of disease: toxicity and nutritional deficiency. On centrifugal juicers, Gerson states:
“When the grinding wheel rotates against a resistance with insufficient access of air, positive electricity is produced and induces negative electricity on the surrounding wall. The exchange of positive and negative ions kills the oxidizing enzymes and renders the juice deficient.”
– Dr. Max Gerson, MD
The decision is yours on whether a cold press or a centrifugal juicer will be the best fit for your lifestyle. Both options are great for different reasons, but also remember that:
- If you are planning to cook or apply heat to the juice then centrifugal will do the trick.
- If you are juicing for medical reasons and need maximum nutrient value then cold press is ideal.
- If you care about dietary fibre, blenders are better for your needs because slow juicers will remove a lot of the fibrous pulp from your juice.
- If you want to extract juice whole apples, nuts, seeds and cores, herbs or leafy greens, cold press juicers are more suitable.
- If you are doing a juice cleanse and are relying on juice as your primary source of nutrients, cold press juicers is ideal (speak to your health care professional about your individual dietary needs).
Grow your own fruits and vegetables, or buy organic, to reduce the amount of pesticides and chemicals that you are consuming. No matter what kind of equipment you have, the quality of your ingredients is paramount.
