| This is obviously due to carbohydrates which act as cryoprotectants and increase in concentration during cold acclimation as well as due to the anthocyanins. |
| In red wines oxygen aids in the formation of pigmented tannins with colours that are more permanent than those of monomeric anthocyanins. |
| Blueberries and strawberries may protect the heart, thanks to naturally occurring red, blue, or purple pigments called anthocyanins. |
| In plants, carotenoid pigments such as anthocyanins often help tackle these aggressors. |
| Sweet cherries, blueberries, and strawberries also contain anthocyanins. |
| Moreover, the level of anthocyanins acylation by acetic acid is out of features for the other Rosaceae plants. |
