Supercritical extraction of grape seed oil at industrial
The plant has been designed considering treating the available grape seeds (≅3000 ton/year, Table 1).The system basically consists of three sections: one for
Grape seed oil extraction: Interest of supercritical fluid
The quality of grape seed oil (free fatty acid, iodine index, saponification index, unsaponifiable fraction, peroxide index, and fatty acid composition) extracted by SFE is similar to that of oil extracted by organic solvent and then refined according to Molero G贸mez et al. [11].
Extraction of oil from grape seeds (V ScienceDirect
A novel green solvent, CO 2-expanded ethanol (CXE), was employed to extract oil from grape seeds, which is one of the main by-products generated by the
Supercritical fluid extraction of grape seed: Process scale
Highlights Grape seeds oils was obtained by supercritical extraction in laboratory and pilot plant scale. The scale-up criterion of constant ratio of solvent to feed mass was successful. Economic evaluation of the process was performed using a commercial software. The best relationship between cost and oil yield was for process conditions of 313 K, 35 MPa, 240 min and S/F of 6.6.
Grape seed oil extraction: Interest of supercritical fluid
At an industrial scale, oil contained in oilseeds is commonly extracted by screw pressing, which is often followed by organic solvent extraction steps to enhance
Supercritical Fluid Extraction of Oils and Waxes from Grape
Grape seeds, a secondary raw material in juice and wine production, are a promising source for obtaining valuable vegetable oil. The yield of grape seeds is 5?% by weight of processed grapes. Depending on the variety and growing location, grape seeds contain 8?0 wt % of fatty oil [1, 2].

Extraction of oil from grape seeds (Vitis vinifera L.) using
Grape seed oil being industrially obtained by solvent extraction, in this study we investigate oil extraction from grape seeds by cold screw pressing, as an alternative extraction process.Effect
Supercritical CO2 extraction of grape seed oil: Effect
The effect of the main process variables affecting the supercritical CO 2 extraction of oil from seeds (namely grape seeds) was investigated, both experimentally
Cold press in oil extraction. A review
Rombaut et al. [15] aimed to investigate the effects of cold press extraction on grape seed oils total phenolic content and optimize the oil yield. Grape seeds obtained from different harvest times were dried up to 7% moisture content at 40 C. Materials and process parameters effect determined by Taguchi experiment design with 12 experiments.
