A grape is a non-climacteric fruit that grows on the perennial and deciduous woody vines of the genus Vitis. Grapes can be eaten raw or used for making jam, juice, jelly, vinegar, wine, grape seed extracts, raisins, and grape seed oil. Grapes are also used in some kinds of confectionery.
Food features:Grapes grow in clusters of 6 to 300, and can be crimson, black, dark blue, yellow, green and pink. "White" grapes are actually green in color, and are evolutionarily derived from the purple grape. Mutations in two regulatory genes of white grapes turn off production of anthocyanins which are responsible for the color of purple grapes.Anthocyanins and other pigment chemicals of the larger family of polyphenols in purple grapes are responsible for the varying shades of purple in red wines.
Nutrition:Grape seed oil from crushed seeds is used in cosmeceuticals and skincare products for many perceived health benefits. Grape seed oil is notable for its high contents of tocopherols (vitamin E), phytosterols, and polyunsaturated fatty acids such as linoleic acid, oleic acid and alpha-linolenic acid.
Dietotherapy function:Commercial juice products from Concord grapes have been applied in medical research studies, showing potential benefits against the onset stage of cancer,platelet aggregation and other risk factors of atherosclerosis,loss of physical performance and mental acuity during aging and hypertension in humans.
