How do you stop pear juice from oxidizing?

1. Use fresh pears. The fresher the pears, the less likely they are to oxidise.

2. Juice the pears immediately. Don't let them sit around cut up, as this will give them time to oxidise.

3. Add an antioxidant to the juice. Some common antioxidants that can be used include lemon juice, ascorbic acid (vitamin C), or metabisulfite.

4. Store the juice in the refrigerator. This will help to slow down the oxidation process.

5. Drink the juice within a few days. Pear juice is best enjoyed fresh.
