Resolvins (Rvs) fall into several sub-classes based on the straight chain PUFA from which they are formed and derive their unique structure. The resolvins Ds (RvDs) are metabolites of the 22-carbon PUFA, DHA (i.e. 4Z,7Z,10Z,13Z,16Z,19Z-docosahexaenoic acid); the resolvins Es (RvEs) are metabolites of the 20-carbon PUFA, EPA (i.e. 5Z,8Z,11Z,14Z,17Z-eicosapentaenoic acid); the resolvins D n-6DPA ...
Anhydrous citric acid. Acidity regulators, or pH control agents, are food additives used to change or maintain pH (acidity or basicity). [1] They can be organic or mineral acids, bases, neutralizing agents, or buffering agents. Typical agents include the following acids and their sodium salts: sorbic acid, acetic acid, benzoic acid, and ...
The grape reaction product (GRP, GRP1 or 2-S-glutathionyl caftaric acid [1]) is a phenolic compound explaining the disappearance of caftaric acid from grape must during processing. [2] It is also found in aged red wines. [3] Its enzymatic production by polyphenol oxidase is important in limiting the browning of musts, [4] especially in white ...
Malic and tartaric acid are the primary acids in wine grapes. The acids in wine are an important component in both winemaking and the finished product of wine. They are present in both grapes and wine, having direct influences on the color, balance and taste of the wine as well as the growth and vitality of yeast during fermentation and protecting the wine from bacteria.
Esters: [2] Ethyl acetate is the most common ester in wine, being the product of the most common volatile organic acid — acetic acid, and the ethyl alcohol generated during the fermentation. Norisoprenoids, such as C13-norisoprenoids found in grape (Vitis vinifera) [8] or wine, [9] can be produced by fungal peroxidases [10] or glycosidases. [11]
Acid is widely used as a preservative. In red wine, Sulfurous anhydride or sulfur dioxide (SO2), in particular, is the most frequently used source. [4] Acid protects wine from bacteria by regulating the pH value, which affects the growth and vitality of yeast during fermentation. [2] Acidity also directly affects color, balance and taste. [2]
Together with anthocyanins and tannins they increase the stability of a wines color-meaning that a wine will be able to maintain its coloring for a longer period of time. The amount of catechins present varies among grape varieties with varietals like Pinot noir having high concentrations while Merlot and especially Syrah have very low levels ...
n-3 DPA is an n-3 fatty acid with the trivial name clupanodonic acid. It is an intermediate compound between eicosapentaenoic acid (EPA 5,8,11,14,17-20:5n-3 or timnodonic acid ) and docosahexaenoic acid (DHA 4,7,10,13,16,19-22:6n-3 or cervonic acid) in the metabolic pathway of DHA in eucaryotes.
