This study concerns papain enzyme assisted synthesis of virgin coconut oil (VCO) as a candidate in-house reference material. The study was conducted to obtain optimization of the VCO preparation with green processes as the standardized product which high stability and homogeneity. The method is expected to produce the candidate of in-house reference material to ensure the standards and quality of the VCO product. Based on the results of this study, the preparation of VCO was carried out using the papain. An optimum yield of 24.30%. was achieved under the following conditions: enzyme to coconut milk with a mass ratio of 0.6 g/L, under 500 mL water/g of coconut powder, at the temperature of 70 °:C by five stages of extraction. The physicochemical properties as well as organoleptic feature of VCO which consist water content, peroxide number, free fatty acids, and iodine numbers are fit with the standard. The parameters exhibited the homogeneity and stability which be able recommended as candidate in-house reference material and have potentially as antibacterial agent. Antibacterial activity test showed that VCO has potential against Escherichia coli, Staphylococcus aureus, Propionibacterium acnes and Pseudomonas aeruginosa as shown by the inhibition zone in the testing.
