Abstract

Vegetable oils are widely produced and consumed in Burkina Faso. The objective of this work is to evaluate the cholesterol level, refractive value and saponification value of crude peanut oils and refined cottonseeds oils produced in Burkina Faso. The study was carried out on 61 samples of refined cottonseeds oils and crude peanut oils collected in Ouagadougou, Bobo Dioulasso and surrounding areas. Cholesterol level was evaluated by HPLC, refractive and saponification values were determined by physico-chemical standard methods. The results show that 64.52% of the saponification value of peanut oils fall within the compliance range of the Codex Alimentarius standard compared to 63.33% for cottonseeds oils. The average saponification values are respectively 192.06 mg KOH/g and 194.16 mg KOH/g for crude peanut oils and refined cottonseeds oils (p>0.05). All cottonseeds oils have refractive value in accordance with the Codex Alimentarius standard while 90.32% of peanut oils have refractive value in accordance with the standard. The average refractive value are 1.468 and 1.471 for crude peanut oils and refined cottonseeds oils respectively (pp>0.05). Almost all cholesterol values of different oil samples are lower to the Codex Alimentarius standard.

布基纳法索生产的植物油中的胆固醇含量

植物油在布基纳法索广泛生产和消费。这项工作的目的是评估在布基纳法索生产的粗花生油和精制棉籽油的胆固醇水平、折光值和皂化值。该研究对瓦加杜古、Bobo Dioulasso及周边地区收集的61份精制棉籽油和粗花生油样本进行了研究。采用高效液相色谱法测定胆固醇水平，理化标准法测定折光值和皂化值。结果表明，花生油的皂化值为64.52%，棉籽油的皂化值为63.33%，符合食品法典标准。粗花生油和精制棉籽油的平均皂化值分别为192.06 mg KOH/g和194.16 mg KOH/g (p < 0.05)。棉籽油折光值全部符合食品法典标准，花生油折光值90.32%符合标准。粗花生油和精制棉籽油的平均折光值分别为1.468和1.471 (p < 0.05)。几乎所有油样品的胆固醇值都低于食品法典标准。
