The Future of Grape Seed Oil: Innovations and Opportunities
The cold pressing method is a preferred technique for extracting grape seed oil due to its ability to preserve the natural nutrients, flavors, and health benefits of the oil. This method involves pressing the grape seeds at low temperatures, typically below 60 degrees Celsius (140 degrees Fahrenheit), to prevent the degradation of the oil's
Grape seed oil has been extracted for many years using organic solvents, usually hexane (Soxhlet method), or pressing mechanical techniques. Solvent extraction is the more expensive method as it requires a purification final step due to the toxicity of the hexane and because it removes pigments and waxes, generating a dark and viscous product.

(approx. 90% efficiency). These data are not for grape seed oil extraction. Goal: A combination of mechanical press and organic solvent leaching process is to be utilized to improve the overall efficiency of grape seed oil extraction. The mechanical deconstruction of the seeds can also improve the performance in solvent extraction stage.
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.

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 and thus depends on the variety. The measured results can
In contrast, hot-press methods bring higher oil yields due to decreased seed oil viscosity at high temperatures, enhancing oil flow. High temperature increases the efficiency of the extraction and yields of up to 80% of available oil (Patel et al., 2016), but it also increases oil degradation, reducing extracted oil quality.
From Seed to Oil: A Step-by-Step Journey Through the Plant
Plant oil extraction techniques are diverse and have evolved over time to cater to various types of plant materials and desired oil qualities. Here, we explore the primary methods used in extracting plant oils: 1.1. Mechanical Pressing Mechanical pressing is one of the oldest and most straightforward methods of extracting oil from oilseeds.
Cold Pressing. The cold-pressing method, as the name suggests, involves pressing the grape seeds without the use of external heat. Mechanical presses exert pressure on the seeds, causing them to release their oil. Since there’s no heat involved, the oil retains more of its natural properties, flavors, and nutrients.
