The consumption trend of the plant-based product has increased over the last few years, from health reasons to the unsustainability of consuming animal product. Plant-based product has been perceived by consumers as products to improve human health and well-being. Plant-based milk substitute such as rice milk is an example of the product and could be made from various rice varieties. Black rice (Oryza sativa L.) is one type of rice that is cultivated in Indonesia. Black rice has been reported to poses antioxidant activity, which is beneficial for health. For this reason, black rice has the potency to be further processed into a functional drink. However, the information regarding the antioxidant and nutritional content in the processed form is still lacking. This research aimed to analyze the antioxidant activity and nutritional content of organic black rice milk. Proximate analysis and antioxidant content (DPPH and total phenol) were conducted in this experiment. The results showed that black rice milk contained 92.36% water, 0.67% fat, 0.14% protein, 0.15% ash, and 6.69% carbohydrate. Black rice milk can inhibit 69.18% activity of 0.2 mmol DPPH radicals. It also contained total phenolic content of 32.75 mg GAE/ 100 mL.
