Abstract
Black rice (Oryza sativa L.) is a nutrient-dense grain notable for its high levels of anthocyanins and antioxidants, offering a range of health benefits. Black rice milk powder, made from black rice, is increasingly recognized as a nutritious plant-based substitute for dairy products due to its beneficial composition and functional qualities. This research examines the manufacturing process, physicochemical attributes, and potential health-promoting effects of black rice milk powder. The production involves steps such as soaking, grinding, enzymatic hydrolysis, filtration, spray drying, and packaging—aimed at preserving nutrients and improving solubility. Nutritionally, the powder is rich in carbohydrates, dietary fiber, essential amino acids, and bioactive compounds like anthocyanins, phenolics, and flavonoids, which are associated with antioxidant, anti-inflammatory, and possible anti-diabetic activities. Unlike traditional dairy milk, black rice milk powder is naturally free from lactose and cholesterol, making it ideal for people with lactose intolerance or those adhering to a plant-based lifestyle. Additionally, the anthocyanins in black rice may offer added benefits such as heart health support, improved metabolism, and possible protection against neurological disorders. Its functional characteristics—such as solubility, stability, and sensory appeal—are essential for its use in various food and beverage products. Technological advancements, including microencapsulation and optimized spray drying, can further improve the stability and absorption of anthocyanins in black rice milk powder.
