You can safely store fresh juice in the refrigerator for 24 to 48 hours, depending on the type of juicer you use. The ideal refrigerator temperature is around 35°F to 38°F (1.5°C to 3.5°C). If you use a centrifugal juicer, your juice will last up to 24 hours (1 day). If you use a chewing squeezer, your juice will last up to 48 hours (2 days).
If you use a Twin Gear juicer, such as the Greenstar Elite, your juice can last up to 4-5 days. In dual-gear juicers, the entire extraction process protects against oxidation, which means that you get fresh juice that stays fresh for longer. It's also worth mentioning that your own fresh juice will go bad much faster than store-bought juice. One thing you should know before freezing your fresh juice is that juice is a lot like water, and when frozen, it can expand.
The only problem with making juice a day in advance is the fact that the juice will start to lose some of its nutrients before you drink it. The amount of heat the juice is exposed to and how it is stored will determine how quickly the juice will oxidize and, therefore, how long it will last in a glass jar. To begin with, the overall quality of the juice is the most important determining factor in determining how long a juice will last in the refrigerator. However, juice is always best when consumed fresh, as juice can take a long time to prepare.
I also like to do enough to make it last 3 to 4 days. If the fresh juice has turned brown, it means that it has oxidized and there is a high probability that the juice has turned rancid. It is normal for those who are new to the world of juices to want to throw everything that comes from a plant into the juicer machine. All of these compounds are found only in fresh juice, not in juice that has been stored for days at a time.
It's another innovative way for commercial juice brands to keep their juice for longer without compromising freshness or quality. You can prepare your juice the night before and preserve some of the nutritional value by storing the fresh juice in an airtight glass container in the refrigerator. Yes, preservatives are often added, but the current commercial squeezing process dramatically increases the shelf life of the juice. Therefore, green juice extracted from a chewing squeezer has more enzymes and greater nutritional value than juice made with the rotating blade of a centrifugal juicer.
If you store your juice in a plastic container, you will inevitably get infected with those chemicals and you won't want to drink it afterwards.
