Effect of Different Foliar Particle Films (Kaolin and Zeolitite) on Chemical and Sensory Properties of Olive Oil

The use of kaolin foliar treatments in olive growing is a well-established approach that aims at protecting crops from the negative impacts environmental stresses and insect pests. zeolite particle films far more recent technique. experimentation was carried out on Correggiolo cv. cultivated Emilia-Romagna region (Italy). Foliar were performed summer until harvest. Ripening index, weight, oil content olives measured. Acidity, peroxide numbers, K232, K270 total phenols evaluated as well fatty acid profiles, determined via GC-FID phenolic compounds; vitamins pigments HPLC-DAD. Quantitative descriptive analysis (QDA) sensory taint tests performed. Olives treated with showed higher contents, obtained exhibited contents phenols, tyrosol deacetoxy oleuropein aglycon respect to oils produced control oil. Oils kaolin-treated profiles characterized by notes berries (that are not typical cultivar). In scenario environment-friendly production, employing zeolitite represent both valid alternative chemical insecticide against fly attack practice has positive influence overall quality.
