Nutritional, Pharmacological and Industrial Applications of Mangosteen and Passion Fruit: A Review

The stunning nutritional and medicinal attributes of tropical fruits have propelled them to international fame. Passion fruit (Passiflora edulis) and mangosteen (Garcinia mangostana) are two examples of such fruits. This review discusses in depth their phytochemical composition, health benefits, and utility in the industrial sector. Mangosteen is an important dietary food and nutraceutical agent that exhibits high antioxidant, anti-inflammatory, antibacterial, and anticancer properties because of its richness in xanthones, anthocyanins, and polyphenols. Passion fruit has the potential to serve as an antidiabetic, antihypertensive, and anticancer agent because it is rich in vitamins (A, B2, and C), carotenoids, and polyphenols. Owing to its antioxidant nature, mangosteen has applications in the cosmetics industry. Passion fruit, however, is extensively used in beverages, pastries, and sweets owing to its flavor and bioactive benefits. This review highlights the numerous uses of these fruits and demonstrates how they can contribute to the areas of sustainable agriculture, medicine, and nutrition. Perishability, limited cultivation, and underutilized by-products (e.g., peels and seeds) are challenges that persist despite their benefits. Enhancing postharvest technologies, boosting agronomic practices, and valoring waste would make them more commercially viable. Enhancing extraction procedures, shelf life, and finding new applications in pharmaceuticals and functional foods are all directions in which future investigations need to focus to provide maximum social, economic, and health gains.
