Shelf life of whole Lake Malawi Tilapia (Chambo) stored in ice

Abstract: 
This study was conducted to determine time when freshly caught Lake Malawi tilapia (Chambo) can remain in acceptable and safe condition for consumers. Sensory, microbiological, and proximate composition analyses including measurement of pH were conducted on fresh fish samples collected from Lake Malawi and stored in ice. The versatile quality index method (QIM) scheme was employed to determine the shelf life of the fish by combining findings from all the analyses. Results demonstrated that with good storage in ice, Chambo can remain in acceptable and safe condition for consumers for up to 16 days.
Cette étude a été menée pour déterminer le temps où le tilapia (Chambo) du lac Malawi fraîchement pêché peut rester dans un état acceptable et sans danger pour les consommateurs. Les analyses de la composition sensorielle, microbiologique, et immédiate, y compris la mesure du pH, ont été effectuées sur des échantillons de poisson frais prélevés dans le lac Malawi et conservés dans la glace. Le plan de la méthode de l’indice de qualité versatile (MIQ) a été employé pour déterminer la durée de conservation du poisson en combinant les résultats de toutes les analyses. Les résultats ont démontré que, avec une bonne conservation dans la glace, Chambo peut rester dans un état acceptable et sans danger pour les consommateurs pour un maximum de 16 jours.

The 2012 RUFORUM Biennial Conference is the third in the series. The main objective of the Biennial conferences is to provide a platform for agricultural research for development stakeholders in Africa and beyond to actively exchange findings and experiences, while at the same time learning lessons towards improving performance of the agricultural sector and ultimately people’s livelihoods. The biennial conference is RUFORUM’s most comprehensive meeting for the diversity of stakeholers in agriculture. It is especially dedicated to graduate students and their supervisors, grantees in RUFORUM member universities and alumni. It is a platform for peer review, quality control, mentorship, networking and shared learning. The third Biennial Conference was attended by 657 participants.This record contains an extended abstract accepted under the theme of Harnessing Aquaculture and Fisheries
