Tamarillo is a sub-tropical fruit known for its unique flavor and color that is highly nutritious and possesses various health benefits. This review summarizes the chemical composition, bioactive properties, and nutritional adequacy of tamarillo from different countries. Tamarillo is rich in vitamins, dietary fiber, and potassium, and is a good source of phenolics, carotenoids, and anthocyanins. It has been found to have antioxidant, anti-obesity, anti-cancer, and prebiotic properties, as well as antimicrobial and antifungal activities. Tamarillo also exhibits higher antioxidant activity than apples and kiwifruit, and its functional applications in various industries are highlighted.
Tamarillo (Solanum betaceumCav.) is a sub-tropical fruit with unique flavour and colour, known to be highly nutritious. Tamarillo has nutritional adequacy score of 7.4 (red type) to 7.9 (gold type) and it is a rich source of vitamins A, B-6, C, dietary fibre and potassium. Phenolics, carotenoids and anthocyanins are considered as the main bioactive components, with 70 volatile compounds and organic acids that contribute to flavour. Potential health benefits include antioxidant, anti-obesity, anti-cancer and prebiotic properties. Anti-microbial and antifungal activities and proteolytic activity have also been demonstrated. This review summarizes chemical composition and bioactive properties of tamarillo from eight different countries (Argentina, Brazil, Colombia, Ecuador, New Zealand, Malaysia, Panama and Taiwan). Information on carbohydrates, dietary fibre, vitamins, minerals, volatiles, phenolic compounds, anthocyanins, total phenolic content and antioxidant activities of tamarillo are compared based on cultivars and geographical sources. Tamarillo possesses higher antioxidant activity than apples and kiwifruit. Applications of tamarillo as a functional ingredient for health, food, cosmetics and pharmaceutical products are also highlighted. Recently reported antimicrobial and antifungal properties make it even more attractive as a functional ingredient to enhance safety and shelf life of foods.
