• Abstract This study aims to compare rice bran quality from different origins and to differentiate rice bran from rice husk based on the spectrum produced by Near Infrared Reflectance Spectroscopy (NIRS) technology. The rice bran used in this study comes from mills and poultry shops in West Java and Sumatra. This study used husks as an adulteration mixing material in rice bran with mixing levels of 25% rice bran: 75% husk, 50% rice bran: 50% husk, and 75% rice bran: 25% husk. Proximate compositions (water content, ash content, ether extract (EE), crude protein (CP), and crude fiber (CF)) were observed. NIRS spectra were collected using the Buchi NIRCal 5.2 application. The results showed an interaction between provider and origin on rice bran EE, CP, and CF contents. Rice bran provided by the miller had better quality with higher CP (17.3% vs. 12.2%) and lower CF (12.0% vs. 16.6%) content in the West Java origin case and higher EE (16.5% vs. 11.1%) in West Sumatera case. The broad spectra distribution showed the variety of the rice bran quality from the poultry shop. The artificial adulteration spectra confirm the impure rice bran quality from the poultry shop.
