Physicochemical parameters of fresh coconut water sold by informal vendors in Goiacirc;nia, Goiaacute;s, Brazil

Abstract

Brazil is a leading global producer of coconuts, with coconut water widely valued for its nutritional benefits and isotonic properties. Ensuring quality and compliance with regulations is essential, particularly for informal markets. On this matter, this study evaluated physicochemical parameters of fresh coconut water sold by street vendors in Goiânia, Goiás, Brazil, to support safety and standardization efforts. For such, 20 specimens were collected between February and April 2024. Samples underwent physicochemical analyses following Adolfo Lutz Institute methodologies, including measurements of pH, titratable acidity, lipids, ash content, and soluble solids, using potentiometric, gravimetric, and refractometric methods. Results revealed significant variations (p
