5]. The antioxidant property of red cabbage extract was confirmed by ferric reducing antioxidant power (FRAP) and 2,2′-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid (ABTS) method (Mizgier et al., 2016). Ethanolic extract of red cabbage (1 g/kg body weight, daily) was found to ...
Red cabbage is full of vitamins (A, C and K), minerals and antioxidants so eating it raw or juicing it also provides a fantastic health boost. Perhaps one of the more unusual qualities of red cabbage is that its juice can act as a home-made pH indicator: it turns red in acidic ...
