Functional foods such as yoghurt made with red or black rice, previously developed, exhibit in vitro an antiproliferative effect on the colorectal cancer cell line. In this context, these studies aimed to assess the antioxidant properties of these types of bioproducts, to establish if this behaviour is due to their antioxidant properties. The postbiotics obtained from these functional foods were analysed by chemiluminescence, and the resulting antioxidant activities were compared with normal yoghurt used as a control. The results revealed that the functional yoghurts with 2.5% fat, containing red or black rice, exhibited high antioxidant activity. In conclusion, the antitumour effect exhibited on the human colorectal tumour cell line in vitro, as shown in previous studies, may also be attributed to the superior antioxidant activity of the new functional foods formulated with black or red rice.
