Proximate Composition of Five Varieties of Spontaneous  Leafy Vegetables Regularly Consumed In Côte D’Ivoire Areas

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.

Aims: The study aimed to evaluate the nutritional and anti-nutritional factors composition of the Solanum torvum fruit. Place and Duration of Study: Department of Food Sciences and Technology, Biocatalysis and Bioprocessing laboratory of Nangui Abrogoua University (Côte d’Ivoire), between June 2019 and March 2020. Methodology: Proximate composition, mineral element profile and phytochemical composition of fresh and boiled S torvum berries were investigated. The S torvum fruit were harvested fresh. One part was cooked in boiling water for 25 min while the other part did not undergo any treatment. These two samples were dried in an oven at 45°C for 72 hours, ground and analyzed according to official analytical method. Results: The results indicated that the boiling caused the loss of nutrients except moisture, fibers and lipids. It was noted a significant reduction of nutrient and anti-nutrients content of berries after boiling. Boiled berries showed a higher energy value (57.07 Kcal) than fresh ones (53.12 Kcal). Despite the boiling, S torvum berries showed high levels of polyphenols (142.54 mg GAE/100g DW (dry weight)), carotenoids (12.96 mg βCE/100g DW), vitamin C (12.03 mg/100 g FW), fibers (6.88%) and ash (7.23%). Minerals analysis of S torvum berries indicated that it is rich in potassium (2046.77 mg/100 g DW), calcium (340.92 mg/100g DW), phosphorus (238.71 mg/100g DW) and magnesium (234.97 mg/100g DW) with high predicted bioavailability for calcium, magnesium and zinc. S torvum fruit contains also iron (7.97 mg/100g DW) and zinc (8.10 mg/100g DW) which are essential for organism. Conclusion: These data indicated that this Solanum torvum fruit consumed in East of Côte d’Ivoire could constitute a potential good source of nutrients for local population.
