Red rice conjugated with barley and rhododendron extracts for new variant of beer

This study aimed to determine the effect and potential of red rice in conjunction with barley and rhododendron extracts to develop a new variant of beer. In this study red rice, barley, and rhododendron extracts were used in different combinations and the best combination was selected based on quality and sensory characteristics. The results showed that the developed beer was rich in antioxidant activity (47.68 ± 0.96) and contained a good amount of anthocyanin (35.12 ± 0.79), flavonoids (0.119 ± 0.002), and polyphenols (0.410 ± 0.002). The red rice has more dietary significance than that of polished or milled rice, further, the use of rhododendron provides a large number of secondary metabolites such as tannins, saponins, alkaloids, tannins, and flavonoids. Besides, the sensory profile of the developed beer was quite distinct in terms of aroma, taste, and color from other alternatives available in the market.
