Nutritional Value and Energetic Properties of Caimito (Chrysophyllum cainito L.) from Southern Nariño, Colombia

Background Caimito ( Chrysophyllum cainito L.), a culturally significant fruit from Nariño, Colombia, remains underutilized due to limited scientific characterization. This study investigates its nutritional composition and predicts the metabolic potential of its proteins through in-silico simulations. Methods A descriptive analysis was performed on fruit samples from San Andrés de Tumaco, analyzed at the CICTA Food Laboratory using AOAC-certified methodologies. Protein metabolism was simulated via bioinformatics tools to estimate peptide-derived energy contributions. Results Caimito is a hydrating, low-calorie fruit (90.97% moisture, 29.41 kcal/100 g), with carbohydrates (8.09 g) and proteins (0.76 g) as primary energy sources. It contains no detectable fats and provides 3.00 g of dietary fiber, supporting digestive health. In-silico analysis identified bioactive peptides with energy contributions ranging from 7.92 to 17.6 kcal, suggesting potential dietary applications. Conclusion Caimito is a refreshing, functional fruit suitable for hypocaloric diets. While its low macronutrient density limits its role as a staple food, its bioactive properties and cultural significance underscore its potential for functional food development. Further research on preservation methods and additional applications is necessary to enhance its nutritional and commercial viability.
