Optimization of oil yield and oil total phenolic content
Grape seed oil expression on screw press enables high oil yield. ?Raw material is the major factor affecting oil expression. ?Oil polyphenols content is independent of seed polyphenols content. ?Playing on process parameter an increase in oil polyphenol content can be reached. Abstract Keywords Oil expression Grape seed Cold screw pressing
Grape seed oil extraction: Interest of supercritical fluid
Grape seed oil has an unusual high smoking point (190–230 C, according to Morin [6]) due to the presence of saturated fatty acids (10%). Additionally, this oil is
Optimization of oil yield and oil total phenolic content
The results show that the studied varieties are suitable for the production of table grape seed oil based on their oil yield, and the oils have favourable, health-protecting properties in terms of

(PDF) Cold press in oil extraction. A review - ResearchGate
Organic solvent extraction gave a high yield of rice bran oil [21,22], but this requires a high temperature, leading to bioactive degradation and energy-intensive steps, including...

The objective of this study was to examine the effect of moisture content, particle size of grape seeds, screw speed and die diameter of mechanical expeller on grape seed oil
Optimization of oil yield and oil total phenolic content
Maximum oil yield was 57.3% and 58.8% (o/o) for type 2 and type 3 grape seed respectively and total polyphenol oil content was below 90 mg GAE/kg for these two types of seeds. Additional experiments were carried out on type 1 seeds to enhance oil yield and oil polyphenol content.
Optimization of oil yield and oil total phenolic content during
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
Bioactive Phytochemicals from Grape Seed Oil-Processing
Oil yield depends on environmental factors, cultivar conditions, grape variety, maturation degree of the seeds, extraction technique, and type of solvent used for extraction. From grape seeds, the oil is obtained in a percentage ranging between 8% and 20% w/w [ 28 ].
