PHYSICOCHEMICAL AND MICROBIOLOGICAL PARAMETERS OF FROZEN ACEROLA PULP (Malpighia emarginata) MARKETED IN PARAISO DO TOCANTINS, BRAZIL

This study evaluated the physicochemical and microbiological parameters of frozen acerola (Malpighia emarginata) pulps sold in supermarkets in Paraíso do Tocantins, Brazil. A total of 48 samples from four distinct brands (A, B, C, and D) were collected monthly throughout 2024. Physicochemical analyses included pH, titratable acidity, total soluble solids (°Brix), total solids, reducing sugars, and ascorbic acid content. Results were compared with the standards established by Normative Instruction SDA No. 37/2018 from the Ministry of Agriculture (MAPA). All brands met the required standards, except for brand C, which showed an ascorbic acid content below the legal minimum. Significant differences among brands were observed, attributed to factors such as ripening stage, processing conditions, and storage practices. Principal Component Analysis (PCA) revealed distinct profiles: brand A showed higher acidity, suitable for products with intense flavor; brand C stood out for its sweeter and more nutritious profile; brand B demonstrated a balance between acidity and sweetness; and brand D presented a less defined profile. Microbiological analyses included coliforms at 45 °C and Salmonella spp., following Normative Instruction No. 161/2022 from ANVISA. All samples were within legal limits, indicating good hygienic-sanitary quality. In conclusion, acerola pulps sold in Paraíso do Tocantins generally exhibit satisfactory quality and are safe for consumption. Continuous monitoring of these parameters is essential to ensure food safety and guide commercial and industrial decisions
