I remember when I first started juicing I peeled a massive amount of mandarins, and made some wonderfully refreshing juice. I had a glass immediately and though that I could put the remaining juice it in a plastic bottle and store it in the fridge, so I could have it for breakfast the next day… but oh dear I was wrong. It tasted awful.
Firstly I made the mistake of using a plastic bottle, and secondly it wasn't airtight so the juice went really bad.
I generally wouldn't recommend storing fresh juice. If you can, get up a little earlier, so you have time to prepare and enjoy a freshly squeezed juice. However, if you are doing a juice fast you will most probably need to take the juice with you, or if you would like to enjoy juice throughout the day e.g. at work, you will have to store it the best you can.
Here is some simple tips which will help keep your juice fresh for longer:
1) Never use plastic bottles as the chemicals in the plastic react with the juice
2) Store in a glass jar
3) Fill it right up and make the jar airtight
4) Store in the fridge
Depending on the type of juicer you are using, you may be able to store the juice for up to 24 hours in the fridge. If using a centrifugal juicer where a greater amount of oxidation occurs, freshly squeezed juice will probably not last any longer than 6 – 8 hours in the fridge.
If using a single – or twin gear juicer (cold-press type) and stored correctly, you may be able to keep it fresh for up to 24 hours, sometimes even up to 48 hours or longer.
