Does Storage Temperature Affect Orange Juice's Acidity?
Does storing your orange juice at different temperatures affects its acidity?
- PH paper
- Orange juice
- Food storage with changeable temperature
- Before you start, pour some orange juice into a cup.
- Put the pH paper into the juice.
- Record exactly what colour it is and if it is very basic, basic, neutral, acidicor very acidic.
- Pour one cup of orange juice into a sealed jar or bottle.
- Put it into the storage apparatus.
- Adjust temperature to 40 – 50 degrees. (If you cannot set a specific temperature, experiment with the settings on the storage apparatus and use the thermometer to know what setting to put it on.)
- Leave the orange juice in for one day.
- Take the orange juice out of storage and put the pH paper into the juice.
- Depending on what colour the pH paper is, the juice should either be very basic, basic, neutral, acidic, or very acidic.
- Make sure to record the exact colour it is. Describe it in detail. Examples: dark red with slightly orange sides, blue with green sides, etc.
