“…They could be antioxidant sources compared to commercial fruits (Sirasa et al, 2014;Silva and Sirasa, 2016). A number of underutilized fruits are adequately rich in antioxidants and phytochemicals besides necessary nutritional components such as vitamins, minerals and dietary fibre (Mallawaarachchi et al, 2015).…”

Five under-utilized fruits, namely Mauritius Plum (Flacourtia inermis Roxb.), Ceylon Olive (Elaeocarpus serratus L.), Tamarind (Tamarindus indica L.), Woodapple (Limonia acidissima L.) and Soursop (Annona muricata L.) were used to produce Ready-To-Serve Fruit Drinks (RTSFDs) while preserving the physical, nutrient and functional properties of the original fruits. The products were developed without added artificial colour, flavour or preservative, but with required shelf-life suitable for market circulation and to ensure high consumer acceptance as a tasty and healthy natural drink. Successful extraction of natural colour, aroma and flavour of the fruits into water was a success with high consumer acceptance. Safe preparation method, maintenance of high acidity levels and safe packaging helped to achieve a long shelf life of 18 months. The newly developed RTSFDs were cost effective and also received high scores on sensory parameters (taste, odour, colour and overall acceptability). Nutritional parameters of RTSFDs such as carbohydrates, protein, total fat and minerals were in the range of 5.98-8.22, 0.01-0.38, 0-0.18 and 1.00-1.86 g/100 ml, respectively. Vitamin C, total phenolic content and antioxidant activity of RTSFDs ranged between 0.15-0.70 mg/100 ml, 12.53-14.57 GAE mg/100 ml and 6.11-7.23, respectively. The production cost of RTSFDs of Mauritius Plum, Ceylon Olive, Tamarind and Woodapple ranged between Sri Lanka Rs 40-50 per unit (250 ml in sealed returnable glass bottle) with a profit margin varying from Rs. 31-39 per unit. Product of Soursop had the highest production cost with the lowest profit margin. Hence, the newly developed RTSFDs could be categorized as low-cost, healthy natural beverages.

“…The damaging intermediates known as reactive oxygen species (ROS) are created during the oxygen metabolism in biological systems. Oxidative stress is a situation brought on by an excess of ROS in the body, which can result in cumulative damage to proteins, lipids, and DNA (Mallawaarachchi et al, 2019). Age-related disorders, cancer, cardiovascular, inflammatory, and neurodegenerative diseases including Parkinson's and Alzheimer's disease are only a few of the pathologies linked to oxidative stress.…”

As a tropical country with high biodiversity, Sri Lanka has a diversified variety of fruits, however most of them remain unexploited. Unfortunately, most Sri Lankans are not aware of those neglected fruit crops and their nutritional value and health benefits. Therefore, this study was carried out to determine the total antioxidant capacity, bioactive compounds and physiochemical properties of nine selected underutilized fruit species in Sri Lanka. Extracts of selected nine unexploited fruits namely, Syzygium cumini (Java plum), Ardisia elliptica (Shoebutton fruit), Eugenia uniflora (Surinam cherry), Antidesma alexiteria (Ceylon bignay), Dovyalis hebecarpa (Ceylon gooseberry), Malpighia emarginata (Barbados cherry), Morus alba (Mulberry), Flacourtia indica (Governor’s plum) and Antidesma bunius (Bignay) were assessed for their total phenolic content (TPC), total flavonoid content (TFC) and total antioxidant capacity (TAC) as well as physiochemical properties. TPC, TFC and TAC were determined by Folin-ciocalteu method, a colourimetric method and ferric reducing antioxidant power (FRAP) assay respectively. The fresh weight (FW), moisture content and total soluble solid (TSS) were also determined. Statistical Analysis was done by analysis of variance (ANOVA) followed by Tukey Multiple Range Test using SAS. The highest fresh weight was observed in Eugenia uniflora (7.31 ± 0.60 g) whereas, the highest moisture content was recorded in Morus alba (88.81 ± 0.48 %). Flacourtica indica had the highest TSS value (19.95 ± 0.71%). Malpighia emarginata had significantly the highest TAC (2623 ± 43.37 mg TE/100 g FW) and TPC (1624.01 ± 71.45 mg GAE/100 g FW) whereas, significantly high TFCs were observed in Flacourtica indica (1374.03 ± 222.61 mg RE/100 g FW) and Syzygium cumini (1305.97 ± 202.17 mg RE/100 g FW). This study concluded that Malpighia emarginata, Syzygium cumini and Flacourtica indica had potent sources of bioactive compounds and antioxidants.
