Suitable container materials
Glass container is the best to store fruit juice, such as wide mouth mason jar, amber jars or glass bottles. A wide mouth jar make it easy to clean juice stains.
Stainless steel water bottles are also good choice. But plastic bottles have the risk of leaching toxins into the fruit juice being stored.
Besides, you’d better choose a small container that allows you to drink up the fruit juice at once, with no need to seal it again.
Seal tightly to prevent air
Air is one of the major factors that cause fruit juice degradation. After you have extracted the fruit juice, fill it into the container at once. Be sure to fill it to the brim or even overfill it a little, then put on the lids on the container. This method can minimize the air contained in the juice bottle.
Also, you can use professional vacuum filling device or a hand-operated vacuum sealer to remove the air from the juice container.
Cold storage or Freeze
After you fill the fruit juice into glass containers and sealed, store it in fridge. Low temperature make the fruit juice last longer. Acidic juice can last for 3-5 days in the fridge, while low-acidic juice can last less than 2 days.
People usually freeze apple cider into ice and preserve for long time. It is not a good way because freezing cause more flavor loss, but you can prevent it going bad at least.
For freezing, don’t fill up the container to allow room for expansion. Leave 0.5 inch at the top. Thaw them in the refrigerator and drink up at once.
Increase the acidity of fruit juice
High acidity can improve the stability of fruit juice. The vitamin C and antioxidant in citrus juice can slow down degradation. Add some lemon juice into your fruit juice to increase the acid content.
