Definition - What does Anthocyanin mean?
Anthocyanin refers to the red, violet or blue pigment which is commonly found in certain plants and flowers. While this pigment is mainly found in higher plants- especially fruits and flowers- it has also been shown to appear in the plant’s roots, stems and leaves. In these cases, anthocyanin is found in the outer cell layers.
MaximumYield explains Anthocyanin
Some plants have been shown to have quite a concentrated amount of anthocyanin. One kilogram of blackberry, for example, can carry nearly two grams of pigment, while black and red legumes carry up to 20 mg of anthocyanin per gram.
According to botanists, the exact color of anthocyanin is heavily dependent on the fruit’s acidity and structure. In fact, some anthocyanins display a blue pigment at less acid conditions and gradually turn red as the climate turns more acidic. Chemically-speaking, this pigment is categorized into sugar-free anthocyanin glycosides and anthocyanidine aglycons. When used in consumables, it is commonly labelled as food additive E163.
