grape seed oil

Grape seed oil has a moderately high smoke point of approximately {{convert|216|°C|°F|abbr=on}}. The oil has a light taste and a high polyunsaturated fat content, making it suitable for use in salad dressings, mayonnaise and as a base for oil infusions of garlic, rosemary, or other herbs or spices. It is widely used in baked goods, pancakes, and waffles. It is sprayed on raisins to help them retain their flavor.

Grapeseed oil may be used as a salad oil, massage oil, and in manufactured cosmetics or

haircare products.{{cn|date=February 2025}}

A study of 21 grape cultivars showed variation of oil composition, especially for linoleic acid and tocopherols.{{cite journal|pmid=22271548|year=2012|last1=Sabir|first1=A|title=The fatty acid and tocopherol constituents of the seed oil extracted from 21 grape varieties (Vitis spp.)|journal=Journal of the Science of Food and Agriculture|volume=92|issue=9|pages=1982–7|last2=Unver|first2=A|last3=Kara|first3=Z|doi=10.1002/jsfa.5571|bibcode=2012JSFA...92.1982S }}

Although grape seeds contain polyphenols, such as proanthocyanidins,{{cite journal|last=Joshi|first=SS|author2=Kuszynski C.

Grapeseed oil has occasionally been found to contain dangerous levels of polycyclic aromatic hydrocarbons because of direct contact with combustion gases during the drying process.{{cite journal|last1=Moret|first1=S.|last2=Dudine|first2=A.|last3=Conte|first3=L.S. |title=Processing effects on the polyaromatic hydrocarbon content of grapeseed oil|journal=Journal of the American Oil Chemists' Society |year=2000|volume=77|issue=12|pages=1289–1292|doi=10.1007/s11746-000-0203-5 |s2cid=97459242|doi-access=free}}

Winemaking accounts for 90% of grape cultivation, with the seeds of the plant serving as a by-product that can be pressed for oil. Grapeseed oil production primarily occurs in wine-growing regions, especially around the Mediterranean Sea.{{cite book | title=The encyclopedia of seeds: science, technology and uses | url=https://books.google.com/books?id=aE414KuXu4gC&pg=PA305 | author1=Bewley, J.

The following table lists a typical fatty acid composition of grape seed oil:{{cite journal|last=Kamel|first=B.

Grape seed oil also contains 0.8 to 1.5% unsaponifiables rich in phenols (tocopherols) and steroids (campesterol, beta-sitosterol, stigmasterol).{{cite journal | title = Microwave Heating of Grapeseed: Effect on Oil Quality | first = BD | last = Oomah |author2=Liang J |author3=Godfrey D |author4=Mazza G | journal = Journal of Agricultural and Food Chemistry| year = 1998 | volume = 46 | issue = 10 | pages = 4017–4021 | doi = 10.1021/jf980412f | bibcode = 1998JAFC...46.4017O | url = https://www.researchgate.net/publication/215523948}} Grapeseed oil contains small amounts of vitamin E, but safflower oil, cottonseed oil, or rice bran oil contain greater amounts.{{cite journal|last=Herting|first=D.
