Science News: Grape skins prevent metabolic disorders

Science News: Grape skins prevent metabolic disorders | agriculture commodities - commodity prices - food sciences | Guarulhos, Brazil. A new Brazilian study found the grape skin extract protected the offspring of normally fed high fat-fed dams during lactation from the phenotypic and metabolic characteristics of metabolic syndrome (J Cardiovasc doctors. June 8, 2011).

The study examined the effect of Vitis vinifera grape skin extract ACH09 (ACH09) on metabolic disturbances and oxidative stress in adult offspring of rats fed a high fat diet (HF) during lactation. Four groups of female rats were fed: control diet (7 percent fat); ACH09 (7 percent fat and 200 mg / kg / d orally ACH09), HF (24 percent fat ), HF + ACH09 (24 percent fat plus 200 mg / kg / d orally ACH09) during lactation for 90 or 180 days.

Systolic blood pressure was increased in adult offspring of HF-fed dams and ACH09 prevented hypertension. The increased adiposity, plasma triglycerides, blood sugar and insulin resistance were observed in the offspring of middle-aged, and these changes were reversed by ACH09. Plasma oxidative damage and increased levels of nitrite decreased in the HF group of middle-aged, which was reversed by ACH09. In addition, restored ACH09 decreased plasma antioxidant activity and mesenteric arteries of superoxide dismutase (SOD), catalase and glutathione peroxidase in the HF group. @food sciences

GRAPE, the source to make wine

GRAPE, the source to make wine - GRAPE is a non-climacteric fruit, especially a berry that grows on the vine and perennial deciduous woody the genus Vitis. Grapes can be eaten raw or they can be used to manufacture jams, juices, jelly, vinegar, wine, grape seed extracts, raisins, molasses and grape seed.oil.. The grapes are also used in some types of confectionery. The grapes are generally ellipsoidal shape, particularly a prolate spheroid.

Domestication of purple grapes originated from Central Asia. Brewer's yeast, one of the first domestic microorganisme, naturally occurs in grape skins, which lead to innovations in alcoholic beverages such as wine. Ancient Egyptian hieroglyphics record the cultivation of the vine purple, and history shows the ancient Greeks, Phoenicians and Romans purple grape wine production, and eating e. As a result, growing grapes used in Europe, North Africa, and finally North America.

Native purple grapes, belongs to the genus Vitis is grown naturally in North America and were part of the diet of many Indians of North America, but considered unsuitable for the European settlers of wine. The first Old World purple grape Vitis vinifera grown in California, where Spain had established a number of functions close to the shore supply ships to prevent scurvy with oranges and convert the natives.

Grapes are a type of berries that grow in groups of 15 to 300, and may be purple, black, dark blue, yellow, green, orange and pink. "White" grapes are actually green, and are evolutionary products of purple grapes. Mutations in two regulatory genes of white grapes turn off production of anthocyanins, which are responsible for the color of red grapes. Anthocyanins and other pigment chemicals of the great family of purple grape polyphenols are responsible for the different shades of purple in red wines. (@ agriculture commodities)
