How to Extract Oil From Grape Seeds

Grape seed oil is often substituted for olive oil in cooking. Cooks like using it because it has a high smoke point and tastes slightly nutty. Grape seed oil's moisturizing and antioxidant properties also make it a popular ingredient in skin creams and lotions. People have been producing grape seed oil for thousands of years, although some methods for extracting the oil are no longer used today. Using an oil extractor is among the most convenient ways to do the task these days.

Instructions

• 1

  Remove seeds from the grape pomace, left over from juicing. Grape pomace consists of grape skins, seeds and stems.

• 2

  Clean the seeds thoroughly. Debri may affect the quality of the oil and damage your oil extractor. Sort out large pieces of debri and run water through the seeds.

• 3

  Lay the seeds on a cloth to dry.

• 4

  Test the seeds' moisture level. Use a hand-held moisture tester to ensure that the moisture level does not exceed 10%. Damp seeds produce very little oil.

• 5

  Plug in the oil extractor and turn it on.

• 6

  Feed the seeds into the oil extractor chute. A metal auger will crush the seeds at a slow speed and the oil will flow into the collection jug.

• 7

  Pour the oil from the collection jug into oil-storing bottles. Seal them tightly with a cork or a screw cap.

• 8

  Store the bottles in a cool, dark place to keep light and heat from affecting the oil's quality and shelf life.
