Abstract

The transformation of mango fruits into dried slices is a way of valuing this fruit. The requirements of good manufacturing practices (GMP) and batch monitoring are not systematically respected. The objective of this work was to study the main factors influencing the sanitary quality of dried mangoes produced in Burkina Faso, emphasizing the importance of implementing a quality approach within the drying units. A survey on dried mangoes units has been performed. Also, toxicological and physicochemical parameters of 60 dried mango samples produced in four towns in Burkina Faso (Bobo-Dioulasso, Banfora, Orodara and Toussiana) have been assayed. Standards methods were used to search each mycotoxins and heavy metals. The production characteristics of the dried mangoes unities were evaluated. The contents of aflatoxins B₁ (AFB₁), B₂ (AFB₂), G₁ (AFG₁), G₂ (AFG₂) and total aflatoxins (B₁+B₂+G₁+G₂) and heavy metals in dried mangoes were evaluated by methods standard. AFB₁, AFB₂, AFG₁ and AFG₂ aflatoxin levels were all below the quantization limit (LOQ). The physico-chemical results showed values between 3.33 to 4.94 for the pH. The humidity levels were between 6.12 to 17.44%. For organoleptic level, results showed a solid and orange-yellow appearance, a sweet and sour smell and taste, without foreign particles. The results showed the presence of heavy metals with values between 0.030 to 0.117 mg/Kg for Cd, 0.040 to 3.470 mg/Kg for Pb, 0.060 to 6. 850 mg/Kg for Cu, 0.370 to 20.740 mg/Kg for Mn and 0.307 to 1.707 mg/Kg for Co. The results obtained provided guidance to producers and researchers in Burkina Faso on the factors that can depreciate the quality of dried mangoes.
