How to conserve natural fruit juices without alcohol?

Question

Sorry if this is not the proper place to ask this. I would like to produce some natural fruit juices to sell, and it must last at least a week once bottled.

It will be made with natural fruit, water, and sugar. I would prefer it to be AS NATURAL AS POSSIBLE.

What can be added to help preserve it longer (as natural as possible)?

Answer 1

This is basically making must but not adding yeast to it and making wine.

I would do one of three things to your juice:

1. Boil the juice(must), or heat to 85 deg C for 15 min, then bottle into sterilised bottles.

2. Treat with a Campden Tablet, then again bottle into sterilised bottles.

3. Pasteurise after bottling as EZ suggests.
