Avaliação da qualidade físico-sensorial do camarão Arco-íris (Parapenaeopsis sculptilis), peixe Malola (Hilsa kelee) e peixe Mapape (Thryssa vitrirostris) comercializados na Praia Nova, Cidade da Beira

Abstract

The assessment of fish quality is crucial for food safety and public health, and is extremely important in the context of informal markets and unstable cold chains, such as in Beira City. The present study aimed to evaluate the physico-sensory quality of Rainbow Shrimp (Parapenaeopsis sculptilis), Malola Fish (Hilsa kelee) and Mapape Fish (Thryssa vitrirostris) commercialized at Praia Nova, Beira City. The research was carried out based on the evaluation of physico-sensory parameters, including color, odor, texture, general appearance, physical integrity and cooking test, using the Quality Index Method (QIM) and the criteria established by the National Fish Inspection Institute (INIP). Samples collected from different marketing stalls were analyzed, and the results were compared with the quality standards established by Mozambican legislation. The results showed that all samples were classified as Quality B (regular), indicating moderate freshness changes, although still acceptable for human consumption. Moderate physical defects and slight sensory changes associated with fish conservation and commercialization conditions were also observed. Despite the identified limitations, the analyzed products generally complied with the legal standards established in Mozambique. It is concluded that the fishery products commercialized at Praia Nova present regular physico-sensory quality, highlighting the need to improve hygienic-sanitary conditions, conservation and fish handling practices to ensure greater commercial quality.
