Soybeans are widely consumed in Indonesia due to their abundant availability, low cost, and high nutritional value. Soybean sprouts, in particular, contain functional bioactive compounds with various health benefits, including stimulating insulin secretion, exhibiting anti-inflammatory activity, and preventing osteoporosis. Soybean sprout drink powder (SSDP) is known to contain isoflavones, which have potential as a natural alternative to hormone replacement therapy (HRT), particularly in osteoporosis management. In addition to isoflavones, calcium and vitamin D contribute to bone health by inhibiting bone resorption and promoting mineralization, with vitamin D enhancing calcium absorption. This study aimed to evaluate the effect of dusting and coating fortification methods on the physicochemical properties and calcium bioavailability of SSDP. The results demonstrated that fortification significantly increased calcium content (56.59 to 149.64 mg/100 g), vitamin D levels (61.09 to 205.32 IU), antioxidant activity (0.99 to 5.60% RSA), calcium bioavailability (9.50 to 33.04%), and hygroscopicity (1.16 to 2.04%). While solubility and viscosity varied, water content decreased significantly, and water activity remained relatively stable. SSDP particles ranged from 13.4 to 16.3 µm in size and exhibited irregular, heterogeneous morphology with occasional surface cracking. In conclusion, the coating method is recommended for producing SSDP with improved physicochemical properties and enhanced calcium bioavailability.
