D 5.3.2.2. Initial report on sensory and African consumer acceptance for Group 2. Project AFTER 'African Food Tradition rEvisited by Research'

The sensory profile and consumer acceptance of Lanhouin, a traditional salted fermented fish made from two types of fish (king fish and cassava fish) and three different fermentation processes (aerobic, semi aerobic and anaerobic condition) were explored. Traditional Lanhouin were sensorially different, with king fish Lanhouin having the highest smell (score of putrid odour) and cassava fish Lanhouin being the whitish. Three classes of consumers' behaviour essentially, those who like all the Lanhouin samples (Lanhouin likers; 35 % of consumers), those who does not prefer king fish Lanhouin from anaerobic fermentation (Lanhouin KFAN dislikers; 37 %) and those who does not like cassava fish Lanhouin from aerobic fermentation (Lanhouin CFA dislikers; 28 %) were identified. Consumers' acceptance was significantly associated with size of fish, whitish colour, dried fish odour and ammoniacal odour. Considering consumers' preference, Lanhouin from king fish with semi aerobic fermentation and Lanhouin from cassava fish (except for aerobic fermentation) were more accepted and could be interesting for reengineering. The similarity in tasting attributes for cassava fish and king fish when used for cooked rice will be helpful to design the form in which Lanhouin can be marketed for large acceptance Considering Kong, no prior work has explored sensory tasting. Four samples were produced for the sensory test: Kong was smoked with wood only and or with wood/coconut. For the sensory evaluation, smoked kong only and smoked kong in sauce and were scored by a semitrained sensory panel. Then, 109 consumers were interviewed. Acceptability was only evaluated on smoked kong. The results show that all four samples were quite distinctive from each other but not when in sauce. Most of the Kong products were on average acceptable but moist kong had a better acceptability than dried kong samples submitted to the same processes of smoking. Consumers were segmented into two three groups as: “indifferent likers” (27%), “dry kong dislikers” (15%), and “dry Kong less preferred” (59%). Clusters really differed in terms of professional activity in fish sector but did not significantly differ in the frequency of consumption. Therefore it appears that, smoked Kong is a main product of consumption in the Senegalese market. Since more than 50% of consumers consumed smoked Kong at least once a week, it appears that Kong is a main product of consumption with a strong potential for the Senegalese market but also for the international market.
