• How are grape seed oils extracted?
  • Traditionally, grape seed oils are extracted with organic solvents, usually n -hexane in the Soxhlet method, or alternatively through the use of pressing mechanical techniques. Extraction with organic solvents leads to a better extraction yield.
  • Are grape seed oil and oil-processing by-products suitable for food and nonfood applications?
  • Due to their contents of nutrients and bioactive molecules, grape seed oil and oil-processing by-products raise interest for use in different fields. A picture of food and nonfood applications of extracts and bioactive compounds from grape seed oil and oil-processing by-products is presented.
  • What is grape seed oil?
  • Grape seed oil, a product derived from seed grape pomace, contributes to the recycling and reuse of winery waste, as well as diversifies the range of value-added products of the wine industry.
  • What is grape seed?
  • Grape seed is an easily obtained byproduct of grape juice and wine processing. Grape seed, storing the majority of polyphenolic content of grape, exhibits rich bioactivities, with promising application prospects in the food industry.
  • Is grape seed oil a functional food?
  • Grape seed oil can be considered a novel functional food due to the high polyunsaturated fatty acids, phenolic constituents, sterols, lignans, and tocopherols [ 29, 30, 31 ]. For this reason, it could be utilized in several applications of the food industry.
