Tamarillo Seeds: Are They Edible and How Should You Use Them?
Often referred to as the tree tomato, the tamarillo is a vibrant, egg-shaped fruit that hails from the high-altitude forests of South America. While the tangy, sweet-tart flesh is the star of the show, many people find themselves pausing at the small, dark tamarillo seeds. You might wonder: are they safe to eat, or should you be meticulously picking them out?
The short answer is a resounding yes. Not only are they edible, but they also pack a nutritional punch that complements the fruit’s overall health profile. In this guide, we will explore the benefits, culinary uses, and even how to grow your own Solanum betaceum from scratch.
What Are Tamarillo Seeds?
If you have ever sliced open a tomato, the interior of a tamarillo will look familiar. This South American native belongs to the Solanaceae family, the same family as peppers and aubergines. The tamarillo seeds are thin, flat, and circular, typically darker and slightly tougher than standard tomato seeds. They are embedded in a succulent, jelly-like pulp that ranges from yellow to deep purple.
Because they are edible seeds, they are meant to be consumed along with the pulp. Unlike some fruit pits that contain cyanide-producing compounds, tamarillo seeds are perfectly safe for human consumption and contribute to the fruit’s unique texture.
The Nutritional Profile
The tamarillo is a nutritional powerhouse, and the seeds contribute significantly to its antioxidant properties. They are rich in phytochemicals that help the body combat oxidative stress. According to research published on Nature.com, these compounds play a vital role in cellular repair.
When you eat the seeds, you are also increasing your intake of dietary fibre. High-fibre diets are essential for maintaining a healthy digestive system and can help prevent various gastrointestinal issues. The NHS recommends increasing fibre intake to support long-term bowel health.
Health Benefits of Consuming Tamarillo Seeds
Integrating these seeds into your diet offers more than just a crunch. They are part of a tropical fruit package that supports several bodily functions:
- Heart Health: Tamarillos are naturally low in sodium and high in potassium. This balance is crucial for blood pressure regulation. Expert advice from the Mayo Clinic highlights how potassium-rich foods can lessen the tension in blood vessel walls.
- Immune Support: The fruit is famous for its high Vitamin C content, which is essential for collagen production and immune function.
- Eye Health: With significant Vitamin A content, eating the seeds and pulp together can help maintain healthy vision and skin. The World Health Organization (WHO) notes that Vitamin A is critical for preventing night blindness.
- Metabolic Boost: The B-complex vitamins found in the seeds help metabolise carbohydrates and fats efficiently.
How to Use Tamarillo Seeds in the Kitchen
The culinary uses for tamarillos are incredibly diverse. Because the skin can be bitter and tough, most people scoop out the pulp and seeds to use in recipes. Here are some popular ways to enjoy them:
- Raw Consumption: Simply cut the fruit in half, sprinkle with a little sugar or salt, and scoop out the pulp and seeds with a spoon.
- Smoothies and Juices: Blend the entire interior of the fruit into a smoothie for an added boost of Vitamin E and fibre.
- Salsas and Chutneys: The seeds add a wonderful aesthetic and textural element to savoury salsas. Check out BBC Good Food for inspiration on fruit-based condiments.
- Dessert Toppings: Use the seed-filled pulp as a vibrant topping for pavlovas, Greek yoghurt, or panna cotta.
Tamarillo Seeds vs. Tomato Seeds: A Comparison
While they look similar, there are distinct differences between these two relatives. The following table breaks down the key characteristics:
| Feature | Tamarillo Seeds | Tomato Seeds |
|---|---|---|
| Colour | Dark brown to black | Pale yellow to beige |
| Texture | Slightly firm and crunchy | Soft and slippery |
| Flavour | Mildly bitter/nutty | Neutral to sweet |
| Digestion | High insoluble fibre | Moderate soluble fibre |
Growing Tamarillo from Seed
If you have fallen in love with the flavour of this fruit, you might want to try seed germination at home. Growing a tamarillo tree is a rewarding project for any gardener interested in exotic species. Information from Kew Gardens suggests that they are relatively fast-growing plants given the right conditions.
Step-by-Step Planting Guide
To begin, extract the tamarillo seeds from a ripe fruit and wash them thoroughly to remove the mucilaginous coating. Dry them in a cool, shaded spot for a few days.
- Preparation: Use a high-quality potting soil mixed with a bit of compost. Ensuring good drainage is vital to prevent root rot.
- Sowing: Place the seeds about 1cm deep in the soil. Keep the soil moist but not waterlogged.
- Seedling Care: Once the seeds sprout, provide plenty of light. According to the Royal Horticultural Society (RHS), young plants are sensitive to frost, so keep them indoors or in a greenhouse during winter.
- Transplanting: When the plant reaches about 15-20cm, move it to a larger pot or a sheltered spot in the garden.

Potential Side Effects and Precautions
While tamarillo seeds are safe for the vast majority of people, those with specific sensitivities to the nightshade family (Solanaceae) should proceed with caution. Some individuals find that nightshades can exacerbate joint pain or inflammatory conditions, though scientific evidence for this is mixed. Detailed health insights can be found on Healthline regarding nightshade sensitivities.
Additionally, always ensure the fruit is fully ripe before consumption. Unripe tamarillos can be quite acidic and may cause stomach upset in sensitive individuals. For those monitoring their intake of specific minerals, WebMD provides excellent resources on how different fruits impact nutrient levels in the blood.
The Bottom Line
Whether you are interested in their antioxidant properties or you simply enjoy the unique texture they add to your meals, tamarillo seeds are a valuable part of the fruit. They offer a simple way to increase your dietary fibre and essential vitamins without any extra preparation. Next time you pick up this exotic fruit, eat the seeds with confidence, knowing you are nourishing your body with every bite.

Frequently Asked Questions (FAQs)
Do I need to peel the seeds before eating?
No, the seeds are very small and do not have a peel. They are consumed whole within the fruit’s pulp. You only need to remove the outer skin of the fruit itself, as it is often tough and bitter.
Can tamarillo seeds help with weight loss?
While no single food causes weight loss, the high dietary fibre content in the seeds can help you feel fuller for longer. This may reduce overall calorie intake. For more on weight management, see advice from Harvard Health.
How long does it take for tamarillo seeds to germinate?
Under the right conditions—warmth and consistent moisture—germination usually occurs within 1 to 3 weeks. Ensuring you use fresh seeds will significantly improve your success rate.
Are the seeds safe for children?
Yes, they are safe for children who are already eating solid foods. However, because they are small, ensure the fruit is mashed or blended for younger toddlers to avoid any potential irritation from the texture.
