The conservation of cola nuts (Cola nitida) poses a real problem in Cote d’Ivoire because of the post-harvest losses. The objective of this study was to evaluate the impact of post-harvest technologies on organoleptic and physical properties of cola nut during storage. A biopesticide, glucose syrup and biopesticide + glucose syrup were applied to fresh cola nuts before conditioning and kept at 28°C for 6 weeks. Physicochemical and sensory analyses were performed to check the quality of the nuts during storage. The results showed that the biopesticide keep cola nuts better than the others methods with only 11.66% ± 3.04% and 13.66% ± 3.95% of loss rates for white and red cola nuts respectively. Cola nuts treated with bio-pesticide retain significantly their freshness with 62.00% ± 1.15% of moisture for white nuts and 64.00% ± 2.00% of moisture for red nuts compared to those treated with glucose syrup and bio-pesticide + glucose syrup (56.66% ± 1.15%). Cola nuts treated with biopesticide have a better acceptability compared to those subjected to others treatments. The use of biopesticide for the storage of cola nuts minimizes the losses and maintains the quality whatever the type of cola.
