Coutaric Acid

	Coutaric Acid Coutaric acid is a hydroxycinnamoyltartaric acid found in wine, pomace and grape. It is an ester formed from coumaric acid and tartaric acid Tartaric acid is a white, crystalline organic acid that occurs naturally in many fruits, most notably in grapes, but also in bananas, tamarinds, and citrus.

	Hydroxycinnamoyltartaric Acid Hydroxycinnamic acids (hydroxycinnamates) are a class of aromatic acids or phenylpropanoids having a C6–C3 skeleton. These compounds are hydroxy derivatives of cinnamic acid. In the category of phytochemicals that can be found in food, there are : * α-Cyano-4-hydroxycinnamic acid * Caffeic acid – burdock, hawthorn, artichoke, pear, basil, thyme, oregano, apple * Cichoric acid * Cinnamic acid – aloe * Chlorogenic acid – echinacea, strawberries, pineapple, coffee, sunflower, blueberries * Diferulic acids * Coumaric acid * Ferulic acid (3-methoxy-4-hydroxycinnamic acid) – oats, rice, artichoke, orange, pineapple, apple, peanut * Sinapinic acid (3,5-dimethoxy-4-hydroxycinnamic acid or sinapic acid) Hydroxycinnamoyltartaric acids * Caftaric acid – grapes and wine, mainly the ''trans'' isomer * Coutaric acid – grapes and wine, both ''trans'' and ''cis'' isomers * Fertaric acid Fertaric acid is a hydroxycinnamic acid found in wine and grapes.

picture info	Wine Wine is an alcoholic drink typically made from fermented grapes. Yeast consumes the sugar in the grapes and converts it to ethanol and carbon dioxide, releasing heat in the process. Different varieties of grapes and strains of yeasts are major factors in different styles of wine. These differences result from the complex interactions between the biochemical development of the grape, the reactions involved in fermentation, the grape's growing environment ( terroir), and the wine production process. Many countries enact legal appellations intended to define styles and qualities of wine. These typically restrict the geographical origin and permitted varieties of grapes, as well as other aspects of wine production. Wines not made from grapes involve fermentation of other crops including rice wine and other fruit wines such as plum, cherry, pomegranate, currant and elderberry. Wine has been produced for thousands of years. The earliest evidence of wine is from the Cau ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
	Pomace Pomace ( ), or marc (; from French ''marc'' ), is the solid remains of grapes, olives, or other fruit after pressing for juice or oil. It contains the skins, pulp, seeds, and stems of the fruit. Grape pomace has traditionally been used to produce pomace brandy (such as grappa, orujo, törkölypálinka, zivania). Today, it is mostly used as fodder, as fertilizer, or for the extraction of bioactive compounds like polyphenols. History "Pomace" is derived from the Latin "pomum" (fruit and fruit tree). The English were the first to use the term "pomace" to refer to the byproduct of cider production. In the Middle Ages, pomace wine with a low alcohol content of three or four percent was widely available. This wine was made by adding water to pomace and then fermenting it. Generally, medieval wines were not fermented to dryness; consequently the pomace would retain some residual sugar after fermenting. Piquette The ancient Greeks and Romans used pomace to create a wine th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
picture info	Grape A grape is a fruit, botanically a berry (botany), berry, of the deciduous woody vines of the flowering plant genus ''Vitis''. Grapes are a non-Climacteric (botany), climacteric type of fruit, generally occurring in clusters. The cultivation of grapes began perhaps 8,000 years ago, and the fruit has been used as human food over history. Eaten fresh or in dried form (as raisins, Zante currant, currants and Sultana (grape), sultanas), grapes also hold cultural significance in many parts of the world, particularly for their role in winemaking. Other grape-derived products include various types of jam, juice, vinegar and oil. History The Middle East is generally described as the homeland of grape and the cultivation of this plant began there 6,000–8,000 years ago. Yeast (wine), Yeast, one of the earliest domesticated microorganisms, occurs naturally on the skins of grapes, leading to the discovery of alcoholic drinks such as wine.

It is commonly mixed with sodium bicarbonate and is sold as baking powder used as a leavening agent in food preparation.
