The microbial analysis showed that Lactobacillus species (9.14 Log cfu/g) as the most important popular microorganism in the paste, followed by enterococci (7.64 Log ufc/g) species, yeasts and moulds (7.30 Log cfu/g) respectively. Sensory analysis revealed significant effects (p < 0.05), of inoculums quantity and fermentation time on the “Attiéké” quality. “Attiéké” obtained with 10% inoculums and after 12 hours of fermentation was identified as the optical inoculums amount and time for “Attiéké” production. The importance of traditional starter inoculums in “Attiéké” processing could be necessary to standardization at small and industrial scale the process of production.展开更多

Our sample was chosen at random. He is constituted by 200 mothers and 200 children aged 0 to-24-month. A questionnaire, beforehand established, is subjected to the mothers. Our statistical analysis is based on the test of Chi2 and the calculation of the percentages. It emerges from our work that: the exclusive breast-feeding is practised by 50.50 % of the cases. The breast-feeding is less practised by the salaried women 40.91 %. The practice of the exclusive feeding increases when the academic level of the mother decreases (50.80% vs. 46.15%), the rate of the mixed feeding and the artificial feeding increases when the academic level increases. The circle of acquaintances plays an important role in the choice of the mode of feeding with 53.47% of the cases. The first food given to the Child within first hour which has followed the childbirth: the maternal milk with 66.5% was. The main causes of the stop of the breast-feeding are: the health of the woman, the incapacity of the milk, the resumption of work the aesthetics of the woman and the arien of a new pregnancy. 72.78%, of the mothers have chooses the breast-feeding because it is better for the health of the child. The average duration of the feeding is of (4.68 ± 4.437 months) the day of the survey. A better information of the population about the feeding and a rationalization of the marketing of industrial milk, could help in a better promotion of the breast-feeding.展开更多
