Cold-Pressed Juice: Does it make a difference?
In the world of juicing, cold-pressed juice is thought to be the best method for processing fruit because it contains more nutrients than when fruit is juiced in other ways. However, the extra expense leads many to wonder if cold-pressing is really worth the money
What does “cold-press” mean?
In a centrifugal juicer, the high speed motor heats up the juicer’s contents. In a cold-press, or masticating, juicer, the contents of the juicer do not heat up as they are processed, hence the term “cold-pressed.”
What’s the difference between cold-press and traditional methods of juicing?
The main difference between the cold-press process and the traditional process of juicing is how the food is treated once it is inside the juicer. A centrifugal juicer uses a high-speed blade to tear the fruit into pieces and relies on centrifugal force to separate the juice from the pulp. A cold-press juicer crushes and presses the fruit slowly to extract juice.
Why does method matter?
Generally speaking, the method you use to make your juice can affect many of its qualities, but in the case of cold-pressed juice, it matters because of the difference in the amount of heat generated by each machine and the level of oxygen exposure.
There are three elements that cause nutrient loss in juice—heat, light, and oxygen. (This is why it is better to consume raw fruits and veggies whenever possible.) Many vitamins are degraded by heat, causing them to lose nutritional value. Additionally, the high-speed blade of the centrifugal juicer exposes the contents to more oxygen, which speeds up oxidation, a chemical process that causes nutrients to lose their effectiveness. Thus, for many juicers whose greatest concern is nutrient intake and therefore, juice’s nutrient retention, it is most important for them to limit the amount of heat and air to which their juice is exposed, and that starts within the juicer.
Is a cold press juicer for you?
You can still receive plenty of nutrients from juice made in a centrifugal juicer like Breville’s Compact Juice Fountain, and the effect that heat has depends on the specific nutrient involved, as some are more susceptible than others. If you are not worried about a little bit of nutrient loss, then a centrifugal juicer will be the less expensive of the two options.
However, if you want to make sure that your juice is as nutrient-dense as possible, the only choice is a cold-press juicer, like the Omega J8006 Nutrition Center Juicer. Their higher price tag means that you need to be sure that juicing is for you before you buy one, which is why we rarely recommend them for beginners.
