Common misconceptions about juicers - part 1

 

FACT: Wattage is mostly irrelevant in slow juicing. Torque (twisiting force) is more important.

In high speed appliances like blenders, food processors, or centrifugal juicers, wattage is indeed inportant. These type of appliances depend on high rpm - up to 20,000 in blenders - which need high wattage motors. Slow juicers operate at much lower rpm - generally between 40 and 110. In these cases a high-torque 150 watt motor is more than enough to process even tough things like carrots or making nut butters. Some cheap juicer manufacturers will compare their juicers to top brands, claiming their higher watt output gives superior results. This simply isn't the case as these motors are often low-torque which stop or make a burning smell when used for more than a few minutes. The top brands from South Korea are equipped with high-quality motors ranging from 150 watts to 240 watts, and we've seen no performance differences between those. 

 

You will find varying claims of maximum storage time for juice with different slow juicers. Some will say 24 hours is the maximum time, while others claim that the juice they produce can be stored up to 72 hours with no loss of taste or nutrition. 

 

 

We always recommend to drink juice immediately after juicing for the best taste and nutrition, or at least within the same day. However, with proper refrigeration (from 2-4 degrees Celsius), slow pressed juice can retain most of its flavor and nutrition for up to 48 hours. This can vary basesd on the quality of the fruit (juice from overripe fruit won't last as long) and the ingredients (citrus fruits contain acid that can slow down the loss of nutrients.)

 

Note that this applies only to slow-speed juicers. Centrifugal juicers aerate the juice at 10,000 rpm, causing oxidation to begin immediately. That's why juices made in a high-speed juicer should be consumed immediately.
