Blood Oranges: Ruby‑Red Citrus Packed with Vitamin C & Anthocyanins
The crimson flesh of blood oranges delivers sweet‑tart flavor plus powerful antioxidant pigments rarely found in other citrus.
What Are Blood Oranges?
Blood oranges (*Citrus × sinensis*, varieties **Moro, Tarocco, Sanguinello**) develop deep red pigments when cool nights follow warm days. Their berry‑like notes set them apart from standard navels.

Potential Benefits
- **Anthocyanins** act as antioxidants that may reduce oxidative stress and support vascular health.
- High **vitamin C** bolsters immune function & collagen synthesis.
- **Soluble fiber** aids satiety and cholesterol management.
- Lower total sugars (~9 g/100 g) than many juices—good for weight‑conscious snacks.
Drawbacks & Precautions
- Acidic juice can erode tooth enamel—rinse with water.
- Some medications (statins, calcium‑channel blockers) caution against large grapefruit intake; blood oranges contain much lower furanocoumarins but consult your doctor if unsure.
Culinary Uses
- Supreme segments over fennel salad with olive oil.
- Reduce juice to ruby **syrup** for cocktails or glaze.
- Bake slices atop upside‑down cakes for dramatic color.
- Pair with dark chocolate; anthocyanins survive gentle baking.
Storage Tips
Keep at **10–13 °C** (cool pantry) up to 2 weeks or refrigerate 3–4 weeks. Zest before juicing; freeze juice in ice‑cube trays for 3 months.
Sustainability Notes
Mediterranean groves often use drip irrigation & integrated pest management. Choose **local, in‑season fruit** (Jan–April in Northern Hemisphere) to minimize transport emissions.
