The following was taken from the Norwalk website to show a comparisons from cold-pressed juicers vs juicers that require you to drink all the juice immediately after it’s been blended or chopped to extract the juice.
The key benefits of the cold-pressed method are:
1. Nutrients and Enzymes Are Preserved.
Because the cold-pressed method does not generate the heat that the centrifugal method does, fewer nutrients and enzymes are killed. From the Norwalk website:
A comparative study of the operation and efficiency of machine “A”, a leading centrifugal juicer; machine “B”, described as being a juicer, grater and homogenizer; and machine “N”, a Norwalk hydraulic press juicer and a chemical analysis of the mineral content of the extract juices. Uniform five pound samples of carrots, parsley, and celery were run on each of the machines with the above results.
2. Higher Yield.
The cold-pressed method extracts much more juice and nutrients from the vegetables and fruit. A Norwalk Juicer and a Breville Norwalk Juicer produces about 50% more juice from a given batch of ingredients.
3. Taste.
The juice from a Norwalk Juicer tastes much better. It tastes cleaner and crisper.
As discussed yesterday, the pressing action won’t oxidize the fruit and vegetables and helps keep the nutrients and enzymes intact vs the grinding juicers.
