Evaluation of Nutritive and Antioxidant Properties of Blanched Leafy Vegetables Consumed in Northern Côte d’Ivoire

Leafy vegetables are highly perishable and often subjected to post-harvest wastes. Among the various methods of preservation, the effect of shadow drying on the nutritive value and antioxidant properties of five (5) leafy vegetables species widely consumed in Northern Côte d’Ivoire was investigated. These species were Amaranthus hybridus, Andasonia digitata, Ceiba patendra, Hibiscus sabdariffa and Vigna unguiculata. Experiment was conducted as follow: portions of washed and drained fresh leafy vegetables (500 g) were spread on clean filter paper and kept in a well-ventilated room of the laboratory at 25°C for 5, 10 and 15 days. The results of proximate composition after 15 days of shadow drying were: moisture (15.19 – 20.36%), ash (9.14 -19.54%), crude fiber (11.04 – 27.40%), proteins (11.14 - 17.94%), lipids (2.41 – 5.86%) and carbohydrates (16.59 – 45.14%). The concentration of minerals increased with respective values after 15 days of shadow drying: calcium (68.14-408.09 mg/100 g), magnesium (50.62-317.23 mg/100 g), iron (27.52-92.03 mg/100 g) and zinc (10.17-16.73 mg/100 g). During shadow drying, vitamin C and carotenoids were subjected to losses estimated to 35.52 – 70.50% and 22.82 – 45.63%, respectively. Contrary to these losses, antioxidant activity increased and ranged from 57.45 to 75.55 % after 15 days of shadow drying. All these results suggest that the considerable nutrient contents of shade dried leafy vegetables make them good source of food supplements in order to meet the nutritional requirements of Ivorian population.

Yeasts And Molds

Aim: It consisted to identify the different species of traditional leafy vegetables consumed, to follow the technical process of production and to specifically evaluate the risk of microbial contamination of Amaranth from urban production in Daloa. Study Design: This study focuses on the consumption of traditional leafy vegetables. Place and Duration of Study: University of Jean Lorougnon Guédé of Daloa, Côte d’Ivoire, Laboratory of Biochemistry and Microbiology, UFR Agroforestry, BP 150 Daloa, between November 2018 and April 2019. Methodology: On the study site, three planks of amaranth leave constituted a study block (sample). A total of 18 samples were analyzed. Then, mature Amaranth, ready for sale and then consumed, were subjected to microbiological characterization according to the standards. Results: There are seven main species of leafy vegetables consumed by Daloa populations and Amaranth is one of the most widely consumed leaves. The monitoring of production of these vegetables revealed that many of the actors were adults (> 30 years old), dominated by the female gender (63 %) and illiterate (70 %). The inputs were poultry manure, a mixture of dung and beef purse. In addition, the technical production routes were empirical. Microbiological analyzes of Amaranth leaf from selected areas showed a high level of bacterial contamination. Including indicator of general pollution like mesophilic aerobic germs, yeasts and molds, enterobacteria and indicator of fecal origin were isolated. It has been noticed the presence of pathogenic species such as Staphylococcus aureus, Escherichia coli and Salmonella sp in all productions. Conclusion: Amaranth leaves produced in this area aren’t suitable for human consumption and could create some sanitary risk.

The City

In Côte d'Ivoire, urban agriculture is expanding in several cities due to its proximity to consumers and its financial benefits. In the city of Daloa, several plant species are cultivated as food crops in market gardens. A survey based on semi-structured interviews was carried out among 19 people at 8 market gardening sites. This sector is controlled by functional illiterate persons who are more than 5 years’ experience. Eleven species included in 9 genera and 8 families and grouped into 5 types of vegetables were recorded. Carrot, Cabbage, Courgette, Spinach, Green Bean, Parsley, Lettuce and Tomato were the most grown vegetable. The most represented families were Apiaceae, Asteraceae and Liliaceae. Leafy vegetables (lettuce, cabbage, parsley) were the most grown. Market gardening generates monthly incomes depending on actor, species, and seasons. Thus, this sector provides an important source of income for local populations and deserves support from authorities.
