Alcohol (chemistry) Ball-and-stick model of an alcohol molecule (R3COH). The red and white balls represent the hydroxyl group (−OH). The three "R"s stand for carbon substituents or hydrogen atoms. [1] In chemistry, an alcohol (from the Arabic word al-kuḥl, الكحل) is a type of organic compound that carries at least one hydroxyl (−OH ...
Wine is a complex mixture of chemical compounds in a hydro-alcoholic solution with a pH around 4. The chemistry of wine and its resultant quality depend on achieving a balance between three aspects of the berries used to make the wine: their sugar content, acidity and the presence of secondary compounds. Vines store sugar in grapes through ...
It is an alcohol, with its formula also written as C 2 H 5 OH, C 2 H 6 O or EtOH, where Et stands for ethyl. Ethanol is a volatile, flammable, colorless liquid with a characteristic wine-like odor and pungent taste. [13] [14] In nature, grape-sugar breaks up by the action of fermentation into alcohol or carbonic acid, without anything being ...
Potassium bitartrate, also known as potassium hydrogen tartrate, with formula K C 4 H 5 O 6, is a chemical compound with a number of uses. It is the potassium acid salt of tartaric acid (a carboxylic acid). In cooking, it is known as cream of tartar. It is used as a component of baking powders and baking mixes, as mordant in textile dyeing, as ...
Ethanol fermentation, also called alcoholic fermentation, is a biological process which converts sugars such as glucose, fructose, and sucrose into cellular energy, producing ethanol and carbon dioxide as by-products. Because yeasts perform this conversion in the absence of oxygen, alcoholic fermentation is considered an anaerobic process.
Other colors used are green for stevia. [1] A sugar substitute is a food additive that provides a sweetness like that of sugar while containing significantly less food energy than sugar-based sweeteners, making it a zero-calorie (non-nutritive) [2] or low-calorie sweetener. Artificial sweeteners may be derived through manufacturing of plant ...
Vinegar. A variety of flavored vinegars, for culinary use, on sale in France. Vinegar (from Old French vyn egre 'sour wine ') is an aqueous solution of acetic acid and trace compounds that may include flavorings. Vinegar typically contains from 5% to 18% acetic acid by volume. [1] Usually, the acetic acid is produced by a double fermentation ...
Infobox references. Tartaric acid is a white, crystalline organic acid that occurs naturally in many fruits, most notably in grapes but also in tamarinds, bananas, avocados, and citrus. [1] Its salt, potassium bitartrate, commonly known as cream of tartar, develops naturally in the process of fermentation.
