Beans cocoa exploitation process generated by-products such as mucilage cocoa juice. This juice called "cocoa water" was often considered as waste because her storage is delicate at room temperature. The aim of this study was to assess self-life of mucilage cocoa juice during storage at room temperature. Consumption survey revealed that mucilage cocoa juice was selflife until 72 hours at room temperature and according to surveyed population, he possessed laxative, strengthening and anti-diarrheal properties. For all physicochemical, biochemical and functional parameters assessed during storage at room temperature, variations were irregulars. Also, mucilage cocoa juice samples have phenolic compounds contents and antioxidant activities important and high energetic values.

Objective : The present study aims to compare the fertilizing quality of green algae (Azolla caroliniana), compost and NPK applied to tomato in the Daloa area (Côte d'Ivoire). The parameters evaluated are the vegetative growth and yield of these tomatoes. Methodology and results : The trial is performed as a randomized, complete block of four treatments (Azolla caroliniana, compost, NPK and Control) in four replicates. Data are collected on the vegetative cycle of crops. The treatments were compared according to the vegetative parameters : stem height (ht), neck diameter (dc), leaf length (lf) and yield (r). Except NPK treatments received 200 kg / ha for NPK and 100 kg / ha for urea, treatments are fertilized at the same manure rate (30 t / ha). The results indicate Azolla caroliniana statically differ. The average of (ht) is 49.37 ± 0.55 cm with Azolla caroliniana against 37 ± 1 cm for NPK, 34.57 ± 2.2 for compost and 22.95 ± 0.24 for control, except the growth of (dc) where the smallest difference was not significant. (Dc) is 0.71 ± 0.08; against 0.57 ± 0.03 for NPK, 0.55 ± 0.08 for compost and 0.42 ± 0.07 for the control. Yield was high with Azolla caroliniana (26.13 ± 0.86 t / ha tomato) at a density of 37500 plants / ha. Conclusion and application of results:This study shows that Azolla caroliniana gives a high yield with a high density, restores good soil fertility and increases the productivity of the tomato crop.
