Tamarillo is a shrub or small size tree reaching about 5-15 feet in height with hairy stems and branches. Its evergreen leaves are broader than in tomato. Well grown plant bears small fleshy pale-pink attractive flowers in the first year of plantation. However, fruiting is discouraged until the plant reaches second or third year.

Tamarillo fruit features oval shape with smooth shiny skin and can be of different colors depending upon the cultivar type. Red tamarillos are more common than orange-yellow varieties. Fully grown fruit features oval, measuring about 6-8 cm in length and 4-6 cm wide, weighing about 100 grams. inside, cut section appears similar to that of in plum-tomatoes. The flesh is juicy, deep in color, sweet yet tangy, flavorful, filled with numerous small flat, circular edible seeds that are slightly larger than in tomatoes.


Health benefits of Tamarillos

  • Tamarillos are one of the very low calorie fruits. 100 g of fresh fruit contain just 31 calories. They contain slightly more calories, fat, and protein than tomatoes. (100 g tomato has 18 calories). Nevertheless, they have good amounts of health benefiting plant nutrients such as dietary fiber (3.3 mg or 9% of RDA), minerals, anti-oxidants, and vitamins.

  • Acidic flavor (sourness) of tree tomatoes mainly comes from citric acid. The other important acid in them is malic acid.

  • The ORAC value (antioxidant strength) of 100 g fresh tamarillos is 1659 TE (Trolex equivalents). Their antioxidant value largely derived from poly-phenolic, flavonol and anthocyanidin compounds. Some of these phytochemicals include chlorogenic acid, kaempferol, and anthocyanin pigments such as cyanidin glycosides, especially concentrated in their skin. Scientific studies suggest that chlorogenic acid help lower blood sugar levels in type-II diabetes mellitus.

  • Yellow and gold variety tamarillo contains more vitamin A and carotenes than red varieties. However, red variety has more anthocyanin pigments. In addition, yellow tamarillos are a good source of carotenes, and xanthins. These compounds possess antioxidant properties and, together with vitamin A, are essential for good visual health. Further, vitamin A is also required for maintaining healthy mucusa and skin. Consumption of natural vegetables and fruits rich in flavonoids help protect from lung and oral cavity cancers.

  • Tree tomato is an average source of B-complex vitamins such as thiamin, riboflavin, and pyridoxine (vitamin B-6). Together, these vitamins help as co-factors for enzymes in metabolism as well as in various synthetic functions inside the body.

  • They are indeed very good source of electrolyte, potassium. 100 g fresh fruit has 321 mg or 7% of this mineral. Potassium is an important component of cell and body fluids helps controlling heart rate and blood pressure; thus, counters the bad influences of sodium. In addition, the fruit contains a small amount of minerals such as copper, manganese, magnesium, phosphorus, zinc and iron.

Preparation and serving methods

Raw ripe fruits can be eaten with peel. However, its skin is bitter in taste (largely because of cyanidin anthocyanin pigments), and many may want to avoid eating it.

Its skin may be peeled and discarded in the similar fashion as in tomatoes. Rinse the fruit in hot-water for 2-3 minutes and cool it immediately by immersing in cold water. Then using a knife, make a small nick on the surface and gently peel using fingers.
