Grape seed separation and drying

Abstract

Following the primary processing of grapes, in the Republic of Moldova are obtained annually 2.0-2.5 thousand tons of grape seeds. Depending on the variety and region of grape cultivation, the seed oil content (calculated on the dry matter) varies from 9.5% to 20.0%. So, from 190 to 512 tons of grape seed oil can be produced, which is demanded on the western market at a price of about $ 50 / kg. According to the scientific literature, red varieties contain 9% less oil than white varieties. The seed content in a ton of grapes is up to 7% of the mass.
