How do you store fresh juice without losing nutrients?

Put the juice in airtight glass containers. First, oxygen degrades the nutrients they provide. Second, the acid in many juices can break down plastic. That's why it's always best to store it in an airtight glass container.

Oxygen cannot enter and degrade nutrients, and no acid can damage glass. This depends on how long you want to keep it and whether you want it to keep its vitamins and nutrients. Keeping juice in the refrigerator ensures that you lose fewer vitamins than you would if it were stored at room temperature. Keeping fresh juice in the freezer will allow you to store it for longer and, in addition, relatively few nutrients will be lost.

Storing freshly squeezed juice in glass bottles or jars helps keep it fresher for longer. This is because glass jars don't allow the juice to oxidize as quickly as a flimsy plastic container would. Juice is even more susceptible to oxidation because when fruits and vegetables are squeezed, the cell walls of the product break down, allowing nutrients to be exposed to air, heat and light and, over time, these factors will contribute to nutrient degeneration. The process for storing the juice of a chewing squeezer is the same as that of a regular juicer, except for the fact that the juice will last longer.

If the freezer is already full, another option for keeping the juice fresh is to use pasteurization. This method eliminates the microorganisms that cause the juice to come off. Storing juice causes some nutrient degradation, so if you start with higher levels of nutrients in the juice, you'll also end up with more in the juice on the third day. A good quality device such as the Philips Avance Collection juicer has a closed system in which the juice is poured directly into the glass or into a jug that you can use to store the freshly made juice in the fridge.

However, it's worth keeping in mind that this process will cause fresh juice to lose more vitamins during the process of heating the juice. If you have to take your juice to work, put it in a small cooler to keep it as cold as possible.
