Grape Seed: physico-chemical, structural characteristics and oil content

Grape seeds from different grape varieties from different growing regions have been studied in terms of the physico-chemical and structural characteristics. Also the content obtained from the seed oil and the quality of the oil were analyzed. The chemical values obtained from the analyzed species, as a percentage of dry matter varies between 8,68 and 9,78 - for protein, between 6,26 and 9,01 - for oil, between 2,14 and 8,28 for Ash and the total of carbohydrates is between 64,72 and 73,01%.
