Global wine production has grown, resulting in an increase in waste within the industry. This has raised concerns among producers and scientists worldwide, prompting them to seek solutions for its management. The aim is to explore the latest advancements in using grape seed oil as a byproduct and its applications within the food industry. To achieve this, a bibliometric analysis was conducted
Traditionally seed oils are extracted either by organic solvent or mechanical techniques. Organic solvent extraction gives better extraction yield, but the technique requires solvent recovery through distillation which may degrade thermally labile compounds; moreover, the presence of traces of residual solvent in the final product makes the process less attractive from health and environmental

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 the global oil yield. However, in the case of seeds with a low oil content such as grape seeds, solvent extraction is preferably used to maximize oil extraction yield [13]. Although
Traditionally, the grape seed oil is extracted mainly by cold pressing and organic solvent techniques. The former method entirely relies on physical and mechanical forces without heating or chemical treatment, obtaining the cold pressing oil that retains the original flavour, but the oil yield is generally less than 9 wt.% [6].

In grape seed composition, around 6?20% is oil [82,83,84,85,86,87,88,89,90,91,92] and its chemical composition depends mainly on the degree of maturation of the seeds employed, the grape variety and many environmental cultivation conditions and to a lesser degree on the seed extraction protocol, as already mentioned [35,109].

At present, products made from grape seeds mainly are grape seed extract, grape seed oil (GSO), and grape seed powder (Ma & Zhang, 2017; Shinangawa, Santana, Torres, & Mancinifiliho, 2015). GSO has been manufactured from as early as the 1930s in Germany, France, and Italy ( Shinangawa et al., 2015 ), and its unique vinous and fruity aroma
- How do you extract oil from grape seeds?
- Oil extraction: Once dried, the grape seeds undergo an extraction process to retrieve the oil they contain. The most common methods include cold pressing, where seeds are mechanically pressed to release the oil without the use of heat, and solvent extraction, where a chemical solvent aids in pulling the oil from the seeds.
- What are the different grape seed oil extraction method & refining process?
- Let's take a look at what are the different grape seed oil extraction method and refining process, what they have and their different features. Grape seed after drying, crushing, humidify, use organic solvent for spraying and soaking, extract grape seed oil from the grape seeds, and then get the crude grape seed oil isolated from mixed oil.
- Which solvent is used to extract grape seed oil?
- The extraction of grape seed oil (GSO) for food and cosmetic applications was performed with 2-methyloxolane (2-MeOx) as a green solvent. The oil extraction yield, the tocopherol and tocotrienol content, the fatty acid and polyphenol profiles of the oils were analysed and compared with hexane.
- How is grapeseed oil extracted?
- The most common methods include cold pressing, where seeds are mechanically pressed to release the oil without the use of heat, and solvent extraction, where a chemical solvent aids in pulling the oil from the seeds. Cold-pressed grapeseed oil is often considered superior in quality due to its preservation of nutrients.
- Do grape seeds need to be dried before extraction?
- Drying: Before extraction can occur, it’s essential that the seeds are dried. This step is crucial to ensure that the oil extracted is of high quality and free from unnecessary moisture, which can influence its taste, aroma, and shelf life. Oil extraction: Once dried, the grape seeds undergo an extraction process to retrieve the oil they contain.
- Which process produces the most oil per grape seed unit?
- Solvent extraction is the most cost-efficient, yielding the most oil per grape seed unit. It achieves this by employing solvents like hexane. The process is designed for bulk operations, making the per-unit cost of oil production lower. However, it might compromise some of the oil’s natural attributes. Cold pressing is a pricier but purer method.
