Chemical analyses and a growth trial were carried out to determine the effect of duration of cooking whole or crushed African locust bean seeds on the proximate compositions, levels of some anti-nutritional factors and growth performance of young rabbits. Samples of whole or crushed African locust bean seeds subjected to 30. 45 or 60 minutes duration of cooking respectively, were analysed for proximate composition and levels of some anti-nutritional factors. In a completely randomized design, a 56-day feeding trial was also conducted using 63 young rabbits of mixed breeds with an average initial weight of 415.00g to evaluate the effect of cooking whole or crushed African locust bean seeds at 100°C for 30, 45 or 60 minutes on growth performance. The diets were formulated to be iso-nitrogenous (20% CP). Diet 1 with raw African locust bean seeds served as the control. The animals were offered feed and water ad libitum. At the end of the growth trial, 5 rabbits per treatment were selected and slaughtered for carcass analysis. The results showed that cooking African locust bean seeds whole or crushed for 30, 45 or 60 minutes had no significant (P>0.05) effect on the proximate composition. However, cooking the seeds, either whole or crushed resulted in a significant (P<0.05) decrease in trypsin inhibitors activity (TIA), phytic acid, tannin und hydrocyanic acid content of the raw seeds. Feed intake, average daily weight gain and feed conversion ratio were significantly (P<0.05) improved as the duration of cooking increased. The cost per unit gain decreased significantly (P<0.05) as the duration of cooking increased from 30 10 60 minutes. It was concluded that ruw African locust bean seeds contain some levels of anti nutritional factors which could limit their nutritional value in monogastric diet. Cooking whole or crushed African locust bean seeds at 100°C for 60 minutes was considered optimum for young rabbits. There was no significant (P>0.05) advantage of crushing before cooking

Les graines de néré (Parkia biglobosa) sont transformées traditionnellement en Afrique de l’Ouest en des condiments fermentés sous différentes appellations : soumbala au Burkina Faso, nététu au Sénégal, soumbara en Guinée Conakry, dawadawa et iru au Nigéria, afitin, iru et sonru au Bénin. Ces produits sont caractérisés par la variabilité de leur qualité et des contraintes liées à leur production. La présente revue a pour objectif d’analyser les technologies traditionnelles utilisées pour la production de ces condiments fermentés à base de graines de néré et de faire ressortir les contraintes/difficultés de production de ces condiments. Les données ont été collectées à travers les documents physiques consultés (thèses et mémoires) et à partir des articles scientifiques et d’autres documents trouvés en ligne. Il en résulte que les technologies de production traditionnelle des condiments à base de graine de néré en Afrique de l’Ouest, incluent principalement selon les zones et les ethnies, une première cuisson des graines allant de 12-48 h, un décorticage manuel des graines cuites, une seconde cuisson des graines décortiquées et lavées variant de 1-4 h et enfin, une fermentation des cotylédons cuits allant de 24-120 h. Ces technologies ont également en commun, des contraintes majeures de pénibilités du processus de cuisson, du décorticage/lavage, de la consommation importante d’énergie, d’eau et de temps. Les données de cette revue ouvrent ainsi de nouvelles pistes de recherche pour l’amélioration des procédés traditionnels de transformation des graines de néré.

R.Br.) en Afrique de l’Ouest : revue des principaux produits dérivés et contraintes de production 15699 Traditional technologies for processing African locust bean seeds (Parkia biglobosa Jacq. R.Br.) in West Africa: review on the main derivatives and production constraints. ABSTRACT African locust bean (Parkia biglobosa) seeds are traditionally transformed in West Africa into fermented condiments under different names: soumbala in Burkina Faso, netetu in Senegal, soumbara in Guinea Conakry, dawadawa and iru in Nigeria, afitin, iru and sonru in Benin. These products are characterized by the variability of their quality and the constraints linked to their production. The objective of this study is to analyze the traditional technologies used for the production of these fermented condiments and to highlight the constraints/difficulties associated to their production. The data were collected through the physical documents consulted (theses and dissertations) and from scientific articles and other documents found online. It appear that the traditional technologies used to produce P. biglobosa seeds based-condiments in West Africa, mainly include, according to the zones and ethnic groups, a first cooking of the seeds ranging from 12-48 h, a manual dehulling of the cooked seeds, a second cooking of the dehulled and washed seeds varying from 1-4 h and finally, a fermentation of the cooked cotyledons ranging from 24-120 h. These technologies have in common the major constraints of hardness of the process of cooking and dehulling/washing, significant consumption of energy, water and time. Data from this review opens research perspectives for the improvement of the traditional processing of P. biglobosa seeds. Keywords: P. biglobosa seeds, condiment, soumbala, process.
