How Long Does Homemade Juice Last In The Fridge?


In this day and age, there are more and more people embracing the nutritional balance concept and following a healthy diet. Many of them choose homemade juice as a daily nutritional supplement. The thing is the time-consuming loop of assembling, processing, dissembling and cleaning up every single day will surely make you bored.

You may then come up with the idea of processing a huge amount of juice at one time and use it for several following days. But here rises the concern: how long does fresh juice last in the fridge? This article will provide you with a reliable answer and give you some helpful bonus tips for keeping your juice fresh for longer. So, let’s dive right in!

How Long Does Homemade Juice Last In The Fridge?

Masticating juice and centrifugal juice shelf-life

If you are a big fan of juicing, you probably already know the two common types of juicers: Masticating and Centrifugal. There are many factors differentiating one from the other, but suffice it to say that the fundamental difference between these two types lies in their rotating speed.

Masticating juicers normally rotate from 80rpm to 110rpm, while Centrifugal ones can speed up to 16,000rpm. Can you spot the problem with the speedy latter? Yes, they generate a lot of heat, and the heat accelerates oxidation rate, which, in turn, gradually degrades the shelf-life of your juice.

A small test conducted by Goodnature in 2016 on two samples of juice (one processed by masticating juicer and one by centrifugal juicer), given that all the ingredients and the storage conditions are the same (at 5 degrees Celsius) reveals that after three days, the amount of Vitamin A dropped off by 65% in the centrifugal sample and only 9% in the masticating juicer.

The scope of the experiment is so small that it can’t give us a general conclusion about the shelf-life of these two types of juice. However, it does give us a hint of how long we should keep our juice in the fridge.

So, as a rule of thumb, if you are using a masticating juicer, your juice can last for 72 hours (three days); but if your juicer is a centrifugal one, you had better use your juice up within 24 hours (one full day).

Mistakes that spoil your juice and how to fix them

Though we have given a recommended storage time for each type of juice, you should keep in mind that there are many other decisive factors which can affect the shelf-life of your juice.

Below is a list of things that you should avoid (doing) if you don’t want to spoil your juice. (And for each of the mistakes mentioned, we’re going to show you a simple yet effective way to fix it, with the aim of keeping your juices fresh longer.)

– Unfresh ingredients

Yes, the freshness of the input vegetables and fruits has a huge impact on not only the taste and the nutrient content but also the shelf-life of the juice.

If the ingredients you feed your juicer are wrinkled, drooping, wilted, or insect-damaged, why should you expect the finished juice would stay fresh over a long period?

So, we highly recommend that you check out tips on identifying and select fresh fruits and vegetables to get the best out of them and maximize storage time.

– Leaving your juice at room temperature for too long before putting it away in the fridge

Be aware that heat is the number one enemy of food preservation. The US Food and Drug Administration classifies juice as perishable and warns that it is unsafe to consume if left out at room temperature for more than two hours.

We hope this piece of information sounds “scary” enough for you to immediately place your juice in the fridge after you process it. Don’t wait until you finish enjoying a cup of juice and cleaning up your juicer. Imagine your juice were Elsa in Frozen 2 and it were singing:

[Put me away]

Don’t make me wait

– Leaving your juice uncovered in the fridge

Some people we know have this weird and harmful habit: putting a glass of drink or a plate of leftover (without covering them) straight into the fridge. It may save them some extra minutes; however, it paves the way for oxygen and bacteria to access and destroy their foods.

If you share the same habit, next time you juice, remember to put your juice in glass jars or bottles (plastic containers may contain BPA, which is detrimental to your health) and cover them carefully to protect your juice from exposure to oxygen and cross-contamination inside the fridge.

– Keeping your juice in the fridge door

Milk, juice, and other kinds of beverages are normally bottled, and the fridge door seems to be a perfect spot for the bottles to stand in.

Nevertheless, the door is the area of the highest temperature in the fridge and is specially designed for storing foods with long shelf-life.

If you place your homemade juice there, the heat will accelerate oxidation and significantly shorten its storage time. Hence, to protect your juice, you had better put it at the back of the lowest shelf – the coolest part of your fridge.

– Putting too much juice in the same container

Masticating juice, as mentioned before, can stay fresh for up to three days in the fridge. You may tend to process a huge amount of vegetables or fruits and then store the whole extracted juice in a big container.

Every day you would take out the container, pour over the needed amount for the day, and then put the rest juice away. This seemingly harmless action causes a sudden fluctuation in the temperature of the juice and adversely affects its quality.

What can you do about it then? Well, we suggest storing your juice into two or three separate bottles (or jars), each for a single-use. By applying this simple technique, you can lift out one bottle a day without touching the remaining juice in other containers.

– Not filling up your container

Do you know that one of the main factors which help food companies to lengthen the shelf life of their products is the way they pack them?

They often pack their food in vacuum bags and fill beverages up to the top of their airtight bottles. This packing technique prevents food and drinks from exposing to air, thereby slowing down the oxidation process.

Now, take some seconds to look at your bottles/jars of juice in the fridge. Does the juice reach the very neck of the bottles/jars? If your answer is “No”, it’s time for you to switch the current containers over to smaller ones that better fit the frequent amount of your juice.

– Setting your fridge temperature too high

Even if you do not make any of the abovementioned mistakes, your juice can still spoil quickly, so do other foods and drinks. The reason for this deterioration may lie in the temperature you set for your fridge. If it is higher than 40 degrees Fahrenheit (4.4 degrees Celsius), the stored food can be contaminated with bacteria quickly because this is the temperature at which bacteria growth starts accelerating. The ideal temperature for storing food of various kinds in the fridge is 35 – 38 degrees Fahrenheit (1.7 – 3.3 degrees Celsius).

If you notice that food and drinks do not stay fresh as long as expected, we suggest checking the temperature that you or your spouse have set for the fridge and adjust it if necessary.


The chief purpose of this article is to help you realize that your food storage habits play a decisive role in how long fresh juice lasts in the fridge.

Now that you are provided with the necessary information, take a few minutes to go through your juice storage habits to figure out whether they fall on the list above or not. Homemade juice is a great source of nutritional supplements, but improper storage may shorten its shelf-life and spoil the quality. We hope you will choose to do the best things for your health.

Thank you for your time and we’ll see you in the next article!
