Yes, you can juice whole oranges, but it's generally recommended to peel them first.
Here's why:
- Peel Concerns: Orange peels can sometimes be treated with chemicals, which you likely want to avoid ingesting.
- Bitterness: The white pith (the membrane between the peel and the orange flesh) can impart a bitter taste to the juice. Peeling removes this, resulting in a sweeter and more palatable juice.
However, if you choose to juice a whole orange (including the peel), be sure to wash it thoroughly beforehand. You might also consider removing some of the pith if you're concerned about bitterness. Keep in mind that different juicers may handle orange peels differently, so refer to your juicer's manual for specific recommendations.
