Purple Tamarillo: The Tangy Superfood You Need for Better Health
If you have ever strolled through a speciality grocery store and spotted what looks like a smooth, egg-shaped tomato with a deep, royal hue, you have likely encountered the purple tamarillo. Often referred to as the tree tomato, this vibrant fruit is a powerhouse of nutrition tucked inside a beautiful, jewel-toned skin.
Native to the Andes mountains, this South American fruit has gained a dedicated following worldwide, particularly as a staple of New Zealand produce. Whether you are looking to boost your immune system or simply want to add a zesty flair to your morning smoothie, the purple tamarillo offers a unique flavour profile that balances tartness with a subtle sweetness.
What Exactly Is a Purple Tamarillo?
Scientifically known as Solanum betaceum, the tamarillo belongs to the Solanaceae family, making it a distant cousin of the tomato, aubergine, and pepper. While red and gold varieties are common, the purple tamarillo is particularly prized for its high concentration of anthocyanins—the same antioxidants found in blueberries and blackberries that give them their rich colour.
The fruit features a firm, edible (though often bitter) skin, a succulent flesh, and small, soft seeds in the centre. Because it is a low-calorie snack, it has become a favourite for those looking to manage their weight without sacrificing nutritional density.
Nutritional Breakdown of the Purple Tamarillo
The nutritional profile of the purple tamarillo is impressive. It is exceptionally high in vitamin A, which is crucial for maintaining healthy vision, and vitamin C, a vital component for immune support and collagen production.
Additionally, it is a significant source of dietary fibre, which aids in digestion and helps maintain a healthy gut microbiome. Here is how the purple variety compares to its colourful counterparts:
| Feature | Purple Tamarillo | Red Tamarillo | Gold Tamarillo |
|---|---|---|---|
| Flavour Profile | Tart and tangy with sweet undertones | Acidic and bold | Sweet and mild |
| Antioxidant Level | Highest (Anthocyanins) | High (Lycopene) | Moderate (Carotenoids) |
| Best Use | Smoothies and salads | Chutneys and sauces | Eating fresh |
| Calorie Count | Approx. 30-40 kcal per fruit | Approx. 30-40 kcal per fruit | Approx. 35-45 kcal per fruit |
Top 5 Health Benefits of the Purple Tamarillo
Incorporating this exotic fruit into your diet provides more than just a pop of colour. Scientific research into Solanum betaceum suggests several key health advantages:
1. Supports Cardiovascular Health
The purple tamarillo is rich in potassium, a mineral that helps regulate blood pressure by balancing the effects of salt. Maintaining a healthy cardiovascular health profile is essential for long-term wellness, and the World Health Organisation emphasises the importance of potassium-rich foods in a balanced diet.
2. Aids in Weight Management
With its high water content and abundant dietary fibre, the tamarillo helps you feel full for longer. It also has a low glycemic index (GI), meaning it does not cause rapid spikes in blood sugar levels, making it a safe choice for those monitoring their glucose levels.
3. Promotes Glowing Skin
The combination of vitamins A, C, and E works as a potent anti-ageing trio. These phytonutrients help protect the skin against oxidative stress caused by pollution and UV rays. For more on how diet affects your complexion, the British Dietetic Association offers excellent resources on skin health.
4. Boosts Metabolic Rate
B-complex vitamins found in the purple tamarillo play a crucial role in maintaining a healthy metabolic rate. These vitamins help the body convert nutrients into usable energy, ensuring you stay active throughout the day.
5. Reduces Inflammation
Chronic inflammation is linked to many modern ailments. The anthocyanins in the purple variety have been studied for their ability to reduce markers of inflammation in the body. Organizations like Arthritis Foundation often recommend antioxidant-rich fruits to help manage inflammatory symptoms.
How to Select and Eat a Purple Tamarillo
When shopping for purple tamarillos, look for fruit that is heavy for its size and yields slightly to gentle pressure—similar to a ripe peach. Avoid any fruit with soft spots or broken skin.
To prepare:
- Scoop it: Cut the fruit in half lengthways and scoop out the pulp with a spoon.
- Peel it: If you want to use the whole fruit in a salad, blanch it in boiling water for 30 seconds to make the skin easy to peel.
- Drink it: Blend the pulp with honey and water for a refreshing traditional South American beverage.
According to the USDA FoodData Central, the seeds are perfectly safe to consume and provide an extra crunch and additional fibre.
The Science Behind the Purple Pigment
The deep violet skin of the purple tamarillo isn’t just for show. Researchers have found that these pigments are anthocyanins, which are being heavily researched for their neuroprotective properties. A study published in Scientific Reports (Nature) suggests that these compounds may help in protecting brain cells from damage. Furthermore, National Cancer Institute research continues to explore how antioxidants like those found in tamarillos might mitigate cellular damage.

Frequently Asked Questions (FAQs)
Can you eat the skin of a purple tamarillo?
Yes, the skin is edible, but it is often quite bitter and tough. Most people prefer to scoop out the sweet-tart flesh or peel the fruit before consuming it in recipes. If you do choose to eat the skin, ensure you wash it thoroughly to remove any surface residues.
Is purple tamarillo better for you than red tamarillo?
While all tamarillos are healthy, the purple tamarillo contains specific anthocyanins that are less prevalent in the red or gold varieties. These provide extra protection against oxidative stress. However, red tamarillos are often higher in lycopene. For a balanced diet, it is best to eat a variety of coloured fruits and vegetables.
How should I store purple tamarillos?
Unripe tamarillos can be kept at room temperature until they soften. Once ripe, they should be stored in the refrigerator, where they will stay fresh for up to two weeks. For long-term storage, the pulp can be frozen or turned into preserves.
Does the purple tamarillo help with digestion?
Absolutely. Because it is high in soluble fibre, it helps to regulate bowel movements and prevent constipation. Fibre is also essential for heart health and maintaining healthy cholesterol levels, as noted by Harvard Health Publishing.
The Bottom Line
The purple tamarillo is an underrated gem in the fruit world. With its striking appearance and dense nutritional profile, it offers a sophisticated alternative to more common fruits. Whether you utilise it for its immune support properties or its delicious, tangy flavour, adding this tree tomato to your diet is a simple way to upgrade your health.
