Evaluation des modes de preparation et de consommation de la tisane de kinkeliba et du cafe touba consommes dans la ville de Dakar au Senegal

Abstract

As a consequence of societies’ evolution, food habits are changing and resulting in serious issues. Consumers are experiencing new foods and new ways of consuming traditional ones. Café Touba and kinkeliba are important beverages in Senegalese diet. Kinkeliba herbal tea is made of a decoction of dry leaves of Combretum micranthum. Café Touba is made by pouring hot water over roasted, ground coffee (Coffea robusta) and Xylopia aethiopica beans through a filter container. Sugar is added to the beverages, which are generally consumed in breakfast or sold in the streets or in small restaurants called Tangana. Many Senegalese, especially the young, are involved into the business. In this study, a survey was conducted in houses, streets and Tangana where the Café Touba and kinkeliba are prepared, consumed or sold. The objective of the survey was to determine methods of preparation and consumption of two local brews in Dakar. Sixty (60) questionnaires were given to the target people to assess the preparation methods and the amount of drinks consumed. Standard methods of preparation of Café Touba and kinkeliba were defined. From these methods, drinks were prepared and used to determine the tannins contents. The added sugar and energy taken for one portion size were also determined. The results showed differences in preparing methods and drinking habits of Café Touba and kinkeliba. The house-made Café Touba was more concentrated than the one prepared and sold in streets or in Tangana. Total dry leaves used for preparing the house-made kinkeliba or sold in streets or in Tangana were similar. Unlike the kinkeliba, the amount of Café Touba consumed in houses for one serving was higher than that in Tangana or in streets. These drinks could be good sources of tannins which have important therapeutic proprieties. However, Café Touba and kinkeliba drinkers could be exposed to an excessive added sugar consumption. In conclusion, Café Touba and kinkeliba are drinks that are well consumed by Senegalese. Promoting these local brews could improve nutrition and health of consumers. However, the high amount of added sugar in these drinks could increase the risk of chronic diseases.
