Physicochemical quality of rice bran pellets using different binder materials

Abstract

Abstract Rice bran is one of the by-products of the agricultural industry that is widely used as animal feed. Rice bran generally exhibits voluminous and dusty characteristics during transportation and storage, requiring special processing techniques to facilitate handling. Pelleting is one of the feed processing techniques that can reduce the volume and dust of feed material, including rice bran. However, one of the determining factors for the quality of pellets is the binder material. This study aims to evaluate rice bran pellets’ physical and chemical qualities using different binder materials: commercial binder LignoBond DD, tapioca flour, corn flour, and sago flour. The research parameters include durability, density, relative density, organic matter content, dry matter content, and crude protein content of the rice bran pellets. The study’s results indicate that the type of binder significantly affected the durability, relative density, and dry matter content but did not affect the rice bran pellets’ density, organic matter content, or crude protein content. The use of 3% corn flour as a binder shows durability and relative density of pellets that are relatively similar to LignoBond DD. Corn flour has the potential for utilization as a binder with similar qualities to LignoBond DD.
