Saturated hydrocarbon content in olive fruits and crude olive pomace oils.
Olive fruits contain an n-alkane series of saturated hydrocarbons mainly in the pulp. Lower amounts of a complex mixture of paraffins, unresolved by gas chromatography (UCM--unresolved complex mixture), have been found in cuticle, stone (woody shell and seed), olive leaves, and talc used as an aid to olive oil extraction. The amounts of both kinds of hydrocarbons are related to the olive cultiv...
متن کاملMicrowave Assisted Extraction of Olive Oil Pomace by Acidic Hexane
In this study, Microwave-Assisted Solvent Extraction (MASE) was used to recover oil residues from pomace olive using acidic hexane. Results obtained demonstrated that oil extraction yield increased with time, the amount of acetic acid in hexane and power radiation. For both radiation powers used (170 and 510W), the optimal extraction time and most interesting content of acetic acid in hexan...
متن کاملNew Olive-Pomace Oil Improved by Hydrothermal Pre-Treatments
The health properties of virgin olive oil (VOO) are well known in the Mediterranean Diet, in which VOO is the main source of fat (Boskou, 2000). The Mediterranean area provides 97% of the total olive production of the world and represents a major industry in the region (Aragon & Palancar, 2001). The fatty acid composition is not the only healthy component of olive oil; in addition, minor compon...
متن کاملOlive oil volatile compounds, flavour development and quality: A critical review
The unique and delicate flavour of olive oil is attributed to the volatile compounds that develop during and after oil extraction from the olive fruit. The formation of these volatile compounds and the fruit characteristics that affect the formation are examined in this review. The role of extraction time -temperature interactions in volatile development and other factors that impact volatile d...
متن کاملDo extraction procedures affect olive oil quality and stability?
Quality and stability of olive oil extracted using discontinuous (pressing) or continuous (centrifuging) procedures were studied. Virgin olive oils extracted from two olive varieties were stored for 17 months. Analytical parameters of oil quality (acidity, peroxide value, polyphenol content, chlorophyll amount, fatty acid composition and triacylglycerol molecular species) were followed at diffe...
متن کاملAnalysis of Possible Noise Reduction Arrangements inside Olive Oil Mills: A Case Study
Apulia (Southern Italy) is the leading Italian region for the production of olive oil (115 × 106 kg of oil/year), and the olive oil chain is really important from a business point of view. Currently, the extraction of olive oil is essentially performed by using a mechanical pressing process (traditional olive oil mills), or by the centrifugation process (modern olive oil mills). The aim of this...
