Abstract A non-destructive fluorescence method combined with chemometric algorithms has been developed for discriminating between olive oils. The excitation-emission matrices (EEMs) of two oil varieties (Arbosana and Oliana) from crop seasons, which had undergone different irrigation treatments (control strategy regulated deficit (RDI)), were recorded. EEMs analysed using parallel factor analys...

Oxidative stability of chia seed oil enriched with oregano (Origanum vulgare L.) and yarrow (Achillea millefolium) extracts at different concentrations (600, 1200, 1800 ppm) was evaluated under accelerated oxidation conditions for 5 days. The total phenolic compounds antioxidant activity extract were higher than the extract. With decreasing increasing time, oxidative decreased significantly ( <...

Abstract Safflower is a minor oilseed crop in Australia where the market is dominated by canola, cottonseed and sunflower. Safflower however offers an alternative oilseed crop in marginal areas. This study was designed to evaluate current safflower lines and to determine their potential value both for edible oil and meal for animal feed. Two sets of samples were analysed. The first was a collec...

The present study aimed to evaluate the changes in extra virgin olive oil (EVOO) after enrichment treatments with Thymus leptobotrys, a Moroccan endemic aromatic plant. EVOO sample was supplemented two materials obtained from aerial parts of T. leptobotrys: powder (2.5 and 5%) or essential (100 200 ppm). chemical composition analysis leptobotrys extracts (essential methanolic extract) allowed d...

In this study, the essential oil chemical compounds of rosemary (Rosmarinus officinalis L.) and its antioxidant activity on oxidation stability refined sunflower (RSO) were investigated by Rancimat method. The plant material was obtained from Afyonkarahisar Medicinal Aromatic Plants Center/Turkey. Based GC/FID-MS analysis result, 1,8-Cineole (15.18%), Camphor (11.39%), Borneol Germacrene D (11....

Os combustíveis fósseis são precursores de uma grande parcela das emissões gases poluentes na atmosfera. Desse modo, existe demanda crescente por fontes energéticas renováveis e menos poluentes. O biodiesel representa alternativa promissora à diversificação matrizes brasiliera mundial bem como para a redução dos impactos ambientais motores combustão interna. Entretanto, o uso do biocombustível ...
