What does a Ninja cold press juicer do?

Juicing has become an increasingly popular way for health-conscious people to get more vitamins, minerals, and nutrients into their diets. Cold press juicers like those made by Ninja offer a great option for making fresh, nutritious juices at home. In this in-depth guide, we’ll take a look at what exactly a Ninja cold press juicer does, who can benefit from using one, and how it compares to other types of juicers.

How a Cold Press Juicer Works

A cold press juicer, also known as a masticating juicer, works by first crushing fruits, vegetables, and leafy greens into a pulpy mush. This is done through a crushing and grinding process with a rotating auger at a very slow speed. The auger squeezes out the juice, separating it from the pulp. The juice then passes through a strainer while the dry pulp is ejected into a separate container.

This slow, grinding process minimizes heat and oxidation, preserving more nutrients and enzymes as compared to fast juicers that work at high speeds using blades that generate heat through friction. The resulting juice from a cold press juicer is extra rich, viscos, and intense in flavor.

Benefits of a Cold Press Juicer

There are several key benefits that make a cold press juicer a great kitchen appliance for juice enthusiasts:

Benefit Explanation
Nutrient Preservation The gentle, slow crushing process minimizes heat and oxidation, preserving more vitamins, minerals, and enzymes.
Juice Yield Cold press juicers extract the maximum amount of juice from fruits and vegetables, leaving dryer pulp.
Juice Quality The juice is extra rich and intense without foaming or separation.
Oxidation Prevention Minimal exposure to air prevents oxidation, so juices last longer.
Versatility Most cold press juicers can juice all kinds of produce from soft fruits to leafy greens.

In addition to juice, some cold press juicer models offer extra functionality like the ability to make nut milk, sorbet, and pasta.

Who Can Benefit from a Cold Press Juicer?

Here are some of the people who stand to benefit most from investing in a cold press juicing machine:

  • Health-conscious individuals seeking more nutrients from fresh, raw juices.
  • Anyone looking to increase their fruit and vegetable intake.
  • People following a juice cleanse or detox diet.
  • Individuals who want to reduce produce waste by juicing pulp and skins.
  • Fitness buffs and athletes looking to supplement their diets.
  • People with digestive issues who find juices easier to break down.
  • Cancer patients undergoing treatment and needing extra nutrition.
  • Those seeking juices with natural enzymes and probiotics.

Comparison to Other Juicers

There are a few other main types of juicers to consider besides cold press models:

Juicer Type How it Works Benefits Downsides
Centrifugal Produce is shredded at high speeds with a rapidly spinning blade. Juice is separated by centrifugal force.
  • Fast juicing
  • Inexpensive models available
  • Louder operation
  • Oxidation and heat minimizes nutrients
  • Not great for leafy greens
Masticating Auger crushes and grinds produce into juice while ejecting pulp.
  • Preserves nutrients and enzymes
  • Extracts high juice yield
  • Versatile for all produce
  • Slower juicing
  • Higher price points
Triturating Two augers work together to fully grind up produce and extract juice.
  • Maximum nutrient preservation
  • Very high juice yields
  • Juices difficult produce like leafy greens
  • Very slow juicing
  • Higher cost

Cold press juicers offer a middle ground between centrifugal and triturating models. They juice at slower speeds than centrifugal models to preserve nutrients better but not as slow as triturating juicers. This makes them a versatile, high performance option.
