Fraksinasi dan Sifat Fisiko-kimia Bungkil Inti Sawit

Abstract

The use of palm kernel meal (PKM) in commercial diet by feedindustry is still lower than 5% (1-3%), one of the factors that limit the optimum use of PKM is shell contamination that may affect integrity of intestinal ville. Therefore fractionation is considered one of the solutions. The aims of the study were to fractionate and characterize physical-chemical properties of PKM. Fractionation of palm kernel meal was done using a vibrator ball mill equipped with sieve of 4, 8, 16, 30, 50, 100 and 400 mesh. Protein, crude fiber, Neutral Detergent Fiber (NDF) and Acid Detergent Fiber (ADF) of the fractionation products were evaluated and the data were analyzed descriptively. Vibrator ball mill was capable of separating shell from PKM. However, the protein content of each fraction was similar. Specific gravity, bulk density, compacted bulk density and angle of repose of PKM were 1.53, 0.56, 0.76 g/mL and 35.44o respectively. It is concluded that fractionation of PKM using vibrator ball mill was capable of separating shell from PKM
