Traditional wisdom and now modern research recognize the health benefits of dark berry antioxidants. Among fruits, dark berries contain high levels of diverse phytonutrients known as polyphenols.Polyphenolsare a large family of natural phytonutrients widely distributed in plant foods.
Some polyphenols are specific to particular food (flavanones in citrus fruit, isoflavones in soya, phloridzin in apples); whereas others, such as quercetin, are found in all plant products such as fruit, vegetables, cereals, leguminous plants, tea, and wine. This article is about larger phenolic substances.olyphenol oxidase (PPO) is an enzyme that catalyses the oxidation of o-diphenols to produce o-quinones. It is the rapid polymerisation of o-quinones to produce black, brown or red polyphenolic pigments that is the cause of fruit browning.
