What Is a Cold Press Juicer and How Does It Work?

Juicing is one of the easiest ways to improve your vitamin and nutrient intake and, thus, your wellbeing while also enjoying the delicious taste of freshly squeezed fruits and veggies.

Cold pressing is one of the most popular ways of juicing. It is a process known for its nutritional and other benefits and the topic of our article today.

What Is a Cold Press Juicer?

 You may have used a lemon juicer to make orange or lemon juice or a centrifugal juicer to make vitamin-packed green juice before. However, when it comes to juicing, there’s no better way to do it than using a cold press juicer.

Also referred to as a cold pressed juicer, this appliance slowly applies pressure to fruits and vegetables to extract nutrient-rich, dense, and delicious juices. The main advantage of the juice made using a cold press juicer is that it is fresh and unpasteurized. This means that most of the nutrients in the pressed fruits and veggies are kept.

Cold press juicers are also known as masticating juicers. They extract juice at a slower speed and preserve it through High-Pressure Processing (HPP). This process kills any harmful bacteria, helps retain more vitamins, minerals, and enzymes, and also increases the juice’s shelf life without using preservatives.

On top of this, using a cold pressed juicer, you don’t only get more from your ingredients in terms of quality. You also get more in terms of quantity. The best cold pressed juicer can extract significantly more juice than a centrifugal juicer and can also juice leafy vegetables without any fuss.

You can get cold pressed juice at a juice bar or make your own using an at-home cold pressed juicer. In the long run, investing in such a juicer makes more sense budget-wise, as you can get fresh and nutritious juices anytime at a fraction of the cost.


How Does a Cold Press Juicer Work? 

A cold pressed juicer does not use heat to make juice. This is particularly important since using heat usually means losing part of the nutrients and vitamins in your ingredients through a process known as oxidation.

Instead, a cold press juicer uses a hydraulic press to slowly extract the juice and enzymes, vitamins, and minerals from the fruits and veggies you put in. This ensures you get higher quality juice, packed with beneficial nutrients. Because the juicing process is slower than with traditional juicers, you also get up to 20% more juice using a cold pressed juicer.

Most cold press juicer Australia models we see today are vertical, but you can also find horizontal models on the market.

Vertical cold pressed juicers tend to be faster than horizontal ones and have a larger feeding chute. This means you won’t have to waste time cutting or chopping your ingredients. They are also easier to clean.

On the other hand, horizontal cold pressed juicers are better at juicing leafy greens like kale, spinach, or chard.

Is Cold Press Juicer the Same as Slow Juicer?

Cold pressed juicing and slow juicing are two terms that are often used interchangeably. This is because, in essence, a cold press juicer is a slow juicer that does not use heat and that slowly presses ingredients to yield more nutrients and make more juice in the process.

Both cold pressed juicers and slow juicers are also referred to as masticating juicers.

How Long Do Cold Press Juices Last? 

You can typically enjoy the juice you make using a cold press juicer for 3 to 5 days. Because this appliance does not use heat and does not oxidise the ingredients, you can enjoy cold pressed juice for longer than the juice you make using a centrifugal juicer. The only requirement is that you keep the juice in the fridge so that it can retain its nutritional value.

On the other hand, if you want to ensure you get all of the benefits cold pressed juice can offer, you should make smaller batches and consume the juice you make on the same day. This is because, after one day, the juice will lose some of its nutritional value and will, therefore, no longer contain all the enzymes, vitamins, and minerals it did initially.  

The general rule is that the fresher the juice is, the more benefits you will reap from drinking it. Not to mention that the juice will always taste better when it is fresher.


Why Should You Use a Cold Press Juicer? 

There are many reasons why you should use a cold press juicer if you want to improve your health and wellbeing. Some of the most important aspects to consider when looking into buying a cold pressed juicer include:


Nutritional Value

By far, the most important benefit of cold press juicers is that they help retain essential nutrients better than any other type of juicer. They do this by gently applying pressure on the fruits and veggies you put in, squeezing out more juice and more vitamins, minerals, and enzymes from your ingredients. They also do this by limiting the exposure of the ingredients to air and preserving the original nutrients and fibres by not using heat and preventing oxidation. 

Traditional juicers use high speeds to process ingredients and, therefore, generate heat. This, in turn, oxidises ingredients and decreases the nutritional value of the juice.

Using a cold press juicer, you can also process more types of ingredients from fruits like lemons and oranges to leafy veggies like kale and spinach. This way, you can mix up the types of nutrients your juice will contain and get more health benefits in the long run.


Maximum Juicing

Another important benefit of cold press juicers is that they yield more juice from your produce. This means less waste and more money saved in the long run. 

With traditional juicers, you waste much of the pulp and end up throwing away more of your fruits and veggies as they are not entirely processed. With a cold press juicer, you can extract more juice that is denser and more nutrient-rich.

If you prefer a lighter consistency, you can add a bit of water to your juices and save even more money and produce.


Reduced Noise 

Given that they use lower speeds to process ingredients, cold press juicers are also notoriously quieter than blenders or other juice-making appliances except for maybe a lemon juicer. 

This is a definite advantage if, unlike the other residents in your home, you are an early bird. It means you can make juice without worrying you will wake up the entire house in the process.  



Saves Money

First of all, the best cold pressed juicer will help you save money by allowing you to make your own nutrient-packed juices at home instead of spending your money at juice bars every day. On top of this, you will also be in full control of the ingredients. Therefore, you will get even better juice at a lower price.

As we already mentioned, another significant way slow juicers help you save money is by processing more of your ingredients. You won’t be wasting any produce using this type of appliance and you will, therefore, buy fewer fruits and veggies to get your vitamin fix.
