Proanthocyanidins (PACs), are polyphenols of high molecular weight widely found in plants and daily foods. They are responsible for many bitter and astringent flavors in food products such as wine, chocolate, beer, and cranberries.
PACs also known as condensed tannins, are the most abundant flavonoids in the human diet. Recent attention has been given to these compounds in the nutraceutical field due to their potential health benefits (e.g. mitigating inflammation, oxidative stress, protecting against cardiovascular disease, etc.)
Proanthocyanidins PAC Assay Kit is based on reaction of 4-dimethylaminocinnamaldehyde (DMAC) with procyanidins’ A cycle’s C8, in terminal units of proanthocyanidin. This reaction produces a green/blue coloured compound that can be measured by spectrophotometry at 640 nm.
