“…The moisture average of peanut oils obtained in this study is higher than the 0.05% but those cottonseeds oils is lower than the 0.06% reported by Zio et al [16]. Also, the peanut oils average is lower than the 0.43% obtained by Soumanou et al [27]. Finally, our average moisture content of cottonseeds oils is lower than the average 0.09% found by Koudougou and Dicko [17] but higher than the value 0.06% of Soumanou et al [27].…”

Aim: The study aim was to assess aflatoxin and moisture levels in edible oils produced and consumed in Burkina Faso to know the impact on consumer health. Methodology: A total of 61 samples of refined cottonseeds oils and crude peanut oils were collected from Ouagadougou, Bobo Dioulasso and surrounding areas. Aflatoxin B1 (AFB1), aflatoxin B2 (AFB2), aflatoxin G1 (AFG1) and aflatoxin G2 (AFG2) were determined by HPLC and moisture by differential weighing after oven drying. Results: The moisture content of peanut oils were ranged from 0.06 to 0.18% and cottonseeds oils from 0.02 to 0.17%. The moisture average is 0.13% for peanut oils and 0.08% for cottonseeds oils (P<0.05). The moisture of all oils is lower and conform to the Codex Alimentarius standard. AFB1, AFB2, AFG1 and AFG2 were identified in 86.89% of the oil samples analyzed. The proportion of samples contaminated with AFB1 is 57.38%, 59.02% for AFB2, 42.62% for AFG1 and 65.57% for AFG2. The AFB1 average of peanut oils is 6.21 ng/g while that of cottonseeds oils is 0.03 ng/g. The AFB2 average of peanut oils is 0.89 ng/g against 0.04 ng/g for cottonseeds oils (P<0.05). The AFG1 average of peanut oils is 0.54 ng/g and 0.08 ng/g for cottonseeds oils (P<0.05). The AFG2 average of peanut oils was 0.66 ng/g against 0.64 ng/g for cottonseeds oils. AFG2 had the highest proportion of all oils while AFB1 has the highest concentration and proportion in peanut oils. The 72.13% samples analyzed in this study comply with the European Community standard for aflatoxin B1 level maximum in oilseeds. Conclusion: Aside from the moisture content that comply with the standard, aflatoxins are present at varying levels and can negatively impact the consumer health. It is important to strengthen the monitoring and production system in order to have quality oil.

“…They are used as raw material in the pharmaceutical, cosmetic, detergent industries... as active ingredient or excipient in the crude or transformed state. The transformation of vegetable oils allows to obtain compounds with improved physicochemical and/or organoleptic characteristics for examples: stability during storage, odor, color...

Linoleoyl macrogolglyceride (LM) and oleoyl macrogolglyceride (OM) are pharmaceutical ingredients, obtained from corn and apricot kernel oils respectively. This study aims to know the detailed chemical composition of LM and OM, in order to understand their roles in pharmaceutical formulations. These two products were analyzed by non-aqueous reversed phase high-performance liquid chromatography (NARP-HPLC), using Vintage Series KR C18 column (250 × 4.6 mm, 5 µm) and non-aqueous acetonitrile/acetone mixture as mobile phase. The ionization source used was atmospheric pressure photoionization (APPI) and the analyzer was LTQ-Orbitrap® (hybrid analyzer: double linear ion trap coupled to a Fourier transform orbital trap). LM and OM consist of complex mixtures, constituted of mono-(MG), di-(DG) and triglycerides (TG) and mono-(MPEGE) and di PEG-6 esters (DPEGE) of linoleic acid (18:2) for LM and of oleic acid (18:1) for OM. NARP-HPLC-APPI method allowed the separation and the identification of the glyceride classes (MGs, DGs and TGs) and the PEG esters of different chain lengths (PEG-chain lengths of fatty acid moieties and number of units of ethylene oxide), at the same time and in one single run, for both products LM and OM. The comparative study between LM and OM showed that, a higher presence of linoleic esters for LM, and a higher presence of oleic esters for OM.
