Episode notes
Why Juice Is Sold As Concentrate
- Concentrate orange juice to reduce shipping weight and microbial risk, then rehydrate at destination.
- Use vacuum evaporation to remove water and freeze or ship syrup concentrate safely.
Don't Eat Oranges After Brushing
- Avoid eating oranges right after brushing because sodium lauryl sulfate in toothpaste blocks sweet and bitter receptors.
- Wait to taste balanced sweetness and bitterness, otherwise the orange will taste harsh and unbalanced.
Fruit Named The Colour
- The English word 'orange' came from Arabic/Persian/Sanskrit roots and named the fruit before the colour.
- Rosie and Manu note orange was a late colour word; fruits named the colour as they spread into Europe.
