Cottonseeds and Crude Peanuts Oils Production Technology and the Edible Oils Sale Conditions in Ouagadougou and Bobo Dioulasso Markets

---

Résumé

This study evaluated production technologies of the refined
cottonseed oils and crude peanut oils and investigated the edible oils' sales
condition in markets of Ouagadougou and Bobo Dioulasso, Africa. Methods:
The study was carried out by administering a questionnaire to 316 edible oil
sellers in markets, 25 cottonseed oil producers, and 18 crude peanut oil
producers. The production technologies and sale conditions such as brands,
origins, storage, and packaging were evaluated on the basis of observations and
surveys. The edible oils' sale conditions, production conditions of the peanut
and cottonseed oils, as well as the means used for production of the aforesaid
oils were investigated. Results: The results showed that the crude peanut oils
were produced in two ways by only women (100%) using rudimentary means.
However, cottonseed oils' production was of three types and mostly dominated
by men (96%). The sodium hydroxide (100%), phosphoric acid (36.4%), citric
acid (63.6%), filters (100%), and tonsil (80%) were used during refining
cottonseed oils. In markets and other places, imported edible oils (94%) were
mainly sold and 34.2% of the sellers exposed oils to the sun. Imported edible
oils generally came from Ivory Coast, Malaysia, and Indonesia. So, local edible
oils were faced with a great competition against the imported oils. These
imported oils are from various origins and are mainly consumed with
deplorable sale conditions. Conclusion: This study highlighted the production
technologies and edible oils' sale conditions. The results of this study can
provide the necessary information for the authorities to take measures to ensure
the quality of edible oils.
