Sugarcanes (Saccharum officinarum L.) are primarily cultivated for sugar production, with molasses as a significant by-product. In the sugar industry, molasses is often considered as industrial wastes, despite its higher mineral content compared to pure sugarcane sap, which underscores its potential as a nutritional resource. In Indonesia, small-scale molasses processing is generally limited to its use as animal feed. This study investigates the utilization of molasses in producing mango-based fruit leather as a functional food product. The study aims to evaluate the antioxidant activity, flavonoid and phenolic contents, tannins, alkaloids, calcium, potassium, and water content of mango fruit leather enriched with molasses. Physical analysis methods included measuring moisture content using the oven-drying method and solubility testing by dissolving the sample in distilled water. A UV-Vis spectrophotometer was used in the chemical analysis procedures to assess the flavonoid, total phenolic, and antioxidant activity (DPPH method). Tannins were identified using the ferric chloride (FeCl3) test, while alkaloid presence was determined using Meyer’s reagent. Calcium and potassium levels were quantified after treatment with nitric acid (HNO3) using atomic absorption spectrophotometry (AAS). Total phenolic content was evaluated using Folin-Ciocalteu method, while flavonoid content was determined using AlCl3 method. The findings revealed that the phenolic content was 7.22 mg GAE/g and the total flavonoid content was 11.97 mg QE/g. Alkaloids were not detected in the samples. The calcium content and potassium content were 25.563 mg/L and 84.820 mg/L, respectively. Physical analysis indicated a moisture content of 1.2%. In conclusion, mango fruit leather enriched with molasses exhibits promising potential as a functional food product, combining nutritional benefits with antioxidant properties. © 2025 Institute of Physics Publishing.
