Extraction of Total Anthocyanins from Sicana odorifera Black Peel Fruits Growing in Paraguay for Food Applications

Sicana odorifera is a native fruit of South America large in size. Its dark-colored skin constitutes useful byproduct for obtaining bioactive molecules because it rich polyphenolic compounds, such as anthocyanins. Obtaining appropriate extracts anthocyanins can be multiple applications the food industry or phytopharmaceuticals. In this work, and its peel composition were evaluated, an anthocyanin extraction system was designed optimized, extract obtained characterized. The S. ripe fruits from black accession growing Paraguay polyphenol compounds Ultrasound-assisted extractions total studied, variables optimized. First, screening design considered to analyze time, pH, liquid–solid ratio, solvent concentration, temperature. From design, significant Box–Behnken response surface methodology applied. resulting characterized by UPLC-DAD-MS / MS-ESI. most efficient at 15 min, 20 °C, pH = 6, 60% ethanol, 80 mL/g ratio. highest concentration 61.908 mg C3G/g extract. extract, 12 main tentatively identified, including five derivatives, flavonol two aglycones. This study provides information obtention anthocyanin-based dye kurugua peel, possibly future natural colorant high-added-value foods due antioxidant characteristics.
