Optimized extraction and quality evaluation of Niger seed oil
Moreover, with the increase in screw press rotational speed, chlorophyll content improves. The possible reason of chlorophyll increase with enhancements in microwave time, PEF intensity, and screw press speed may be the high solubility and penetration of the chlorophylls into the extracted oil sample as reported in the study of (Megahed, 2001).

Optimization of oil yield and oil total phenolic content
Effect of grape seed type. Taguchi design showed that grape seed type is by far the most significant factor: oil yield, oil polyphenol content, press capacity and oil temperature were all together significantly affected by the raw material with p-values lower or close to 0.01 (Table 3).
between 21.9 – 26.6 g, humidity between 5.6 – 7.1% of dry matter and seed oil content, determined by extraction and depending on the variety, ranges from 15.3 to 17.5% in dry basis.
Extracting oil from grape seed using a combined wet enzymatic
A combination of wet enzymatic extraction and pressing was used to extract grape seed oil without generating an oil-in-water emulsion or wastewater. The steps of this specific process include wetting, softening, cracking, enzymolysis, drying, and pressing. Technological aspects, such as enzymatic hydrolysis conditions and correct screw-press
The oil extraction by mechanical pressing is the most common method for continuous treatment of oleaginous seeds without solvent. Different types of presses can be used depending on the purpose (expeller, expander, and twin-screw extruder) and on the capacity range (3 kg h−1 to 150 t day−1). At the laboratory scale, many authors have highlighted the effect of operating parameters (screw
Evaluation of the pressing process during oil
This means that one kilogram of seed may produce 67.5 to 98.5 g of oil. The quantity of the pressed oil ranges from 67.5 to 98.5 g.kg⁻¹ and thus depends on the variety. The measured results can

"Optimisation of supercritical CO2 extraction of grape seed
Under these optimal conditions, the predicted extraction oil yield was 14.49% and DPPH 37.07%. Applying this green extraction method, the oil from grape seeds was totally extracted. The produced oil was of satisfactory quality, and the content of α-tocopherol in obtained grape seed oil at optimal extraction conditions was 36.05 mg kg −1.
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
