Optimization and validation of a simplified methodology for simultaneous extraction of fatty acids and tocopherol homologues in peanuts

A new sample treatment methodology was developed for the simultaneous determination of oleic, linoleic, palmitic and stearic fatty acids (FA), α-, β-, γ- δ-tocopherol homologues in peanut samples. Usually, these compounds is carried out after oil extraction with an organic solvent at boiling temperatures solvent. The innovative analytical this work performed a 20 mL vial which FA tocopherols were simultaneously extracted, derivatization was, afterwards, conducted. reduction analysis time from 1 h 30 min (reference methodology) to (new increased throughput. Furthermore, amount used decreased 40 6 validated based on certified reference butter results compared those obtained by using suitable agreement values found. Finally, approach analyse toasted fried (with without tegument) peanuts.
