Juices can be stored in the fridge for 24 to 48 hours and up to 72 hours maximum. When you need to store juices for a longer time, you should freeze them. If they freeze, it is recommended not to fill them to the top to leave room for them to expand. Leave at least ½ inch at the top.
Finally, the most natural option used by most cold-pressed juice bars is not to treat their juices. It's also worth mentioning that your own fresh juice will go bad much faster than store-bought juice. It's another innovative way for commercial juice brands to keep their juice for longer without compromising freshness or quality. When microorganisms in the air enter the juice container, they begin to ferment the fruit, which changes the taste and aroma of the juice.
So how long does the juice last? When properly stored, the shelf life of fruit juice after its expiration date is approximately. Just as oxidation takes over raw and cut fruits and vegetables, the same can happen to fresh juice if you don't drink it or protect it soon after you squeeze it. Juices that are all fruit juices spoil sooner than juices with added sugar and preservatives, since the natural sugars in the fruit will begin to ferment over time. For the time being, there are non-thermal preservation alternatives that leave the organoleptic and nutritional quality of the juice practically unchanged, ensuring that it remains similar to natural juice.
As a result, the taste and some properties of the juice are affected; in fact, some consumers believe that this process gives the juice a cooked flavor. 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. And as mentioned above, the juice from the chewing squeezers lasts longer than the juice from the centrifugal juicers. Yes, preservatives are often added, but the current commercial squeezing process dramatically increases the shelf life of the juice.
Placing fresh juice in the freezer immediately after you squeeze it can last up to six months, but some nutrients will be lost in the process. 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.
