  abstract = {{V}itamin {A} deficiency is still one of the major public health problems in least developed countries. {F}ortification of vegetable oils is a strategy implemented worldwide to prevent this deficiency. {F}or a fortification program to be effective, regular monitoring is necessary to control food quality in the producing units. {T}he reference methods for vitamin {A} quantification are expensive and time-consuming. {A} rapid method should be useful for regular assessment of vitamin {A} in the oil industry. {A} portable device was compared to high-performance liquid chromatography ({HPLC}) for three plant oils (rapeseed, groundnut, and soya). {T}he device presented a good linearity from 3 to 30 mg retinol equivalents per kg (mg {RE}.kg(-1)). {I}ts limits of detection and quantification were 3 mg {RE}.kg(-1) for groundnut and rapeseed oils and 4 mg {RE}.kg(-1) for soya oil. {T}he intra-assay precision ranged from 1.48 % to 3.98 %, considered satisfactory. {A}ccuracy estimated by the root mean squares error ranged from 3.99 to 5.49 and revealed a lower precision than {HPLC} (0.4 to 2.25). {A}lthough it offers less precision than {HPLC}, the device estimates quickly the vitamin {A} content of the tested oils from 3 or 4 to 15 mg {RE}.kg(-1).},
