The study was carried out in order to establish the suitability of fermented soybean condiment as an alternative to fermented locust bean condiment in meal preparations. The dried fermented condiments were subjected to chemical, microbial and sensory evaluation using standard methods. Results revealed significantly (p<0.05) higher protein (54.06%), ash (6.21%), crude fat (14.15%) and pH (8.90) content in fermented soybean condiment. Higher values of 44.72 mg/100 g, 20.06 mg/100 g, 612.40 mg/100 g and 164.34 mg / 100 g were also observed in fermented soybean condiment with respect to iron, magnesium, potassium, and calcium respectively. Furthermore, fermented soybean condiment revealed significantly (p<0.05) higher vitamin content of 647.62 UI/100 g, 0.047 mg/100 g and 0.030 mg/100 g for pro-vitamin A (β-Carotene), vitamins B1 and B2 respectively. Microbiologically, total plate count of 1.7×105 CFU/g and 1.4×105 CFU/g were observed for fermented soybean and locust bean condiments respectively. There was however no fungal growth observed in both condiments. Isolation and characterization of bacteria isolates revealed Bacillus subtilis as the common microorganism in both condiments. Bacillus licheniformis was predominant in locust bean condiment, while Bacillus pumilus was more in soybean condiment. With the exception of appearance, there was no significant difference (p>0.05) between the condiments in terms of their sensory attributes. Sensory scores for fermented soybean condiment were however higher than that of fermented African locust bean. From this study, soybean condiment may be a suitable substitute to locust bean (Parkia biglobosa) condiment, following the gradual extinction of the plant.

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.) 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.
