Avaliação do grau de frescura e nutricional do Camarão- Branco, Magumba e Carapau comercializados no mercado Xiquelene - Maputo

Abstract

Fish is a generic term that includes fish, crustaceans, mollusks, and algae. In the interval between capture and commercialization, fish is subject to quality losses (physicochemical, sensory, and microbiological) due to storage conditions on board and the nature of its composition, which may result in alterations in chemical, physical, or microbiological characteristics, leading to sensory changes. With the aim of evaluating the degree of freshness and chemical composition in fish (White Shrimp - Penaeus Indicus, Magumba - Hilsa Kelee, and Horse Mackerel - Trachurus trachurus) sold at the Xiquelene Market, the samples were subjected to sensory analysis, pH determination, and moisture, ash, and protein content. All laboratory tests were carried out at the Fish Inspection Laboratory (LIP). The fish presented an acceptable quality for consumption, with fresh sensory analysis results ranging from regular to good among the samples. Average pH values ​​of 6.71±0.330 in Shrimp - Penaeus Indicus, 6.50±0.088 in Magumba - Hilsa Kelee and 6.83±0.432 in Horse Mackerel - Trachurus trachurus, where no significant differences were found and they were within acceptable limits for fresh fish.

Average moisture values ​​of 70.21±0.903 in Shrimp - Penaeus Indicus, 73.85±1.406 in Magumba - Hilsa Kelee and 71.45±2.420 in Horse Mackerel - Trachurus trachurus, where no significant differences were found and they are within acceptable limits. Average Ash values ​​of 2.26±0.186 in shrimp - Penaeus Indicus, 1.41±0.067 in Magumba-Hilsa Kelee and 1.52±0.081 in horse mackerel - Trachurus trachurus with significant differences and are within the established limits except for the average Ash content in Shrimp and average Protein values ​​of 22.01±0.360 in Shrimp - Penaeus Indicus, 16.85±0.738 in Magumba-Hilsa Kelee and 19.59±0.668 in horse mackerel - Trachurus trachurus where they revealed significant differences between the samples and were within the established limits(TRADUÇÃO NOSSA)
