Studies on bleachability of palm kernel oil, olein and stearin : Optimum conditions and effects on composition and quality

The optimization of small scale refining for the Seed Crushers and Oil Processors’ Association (SCOPA) was studied. The performance of three types of bleaching earths, WACSupreme, Pure-Flo, SBE Gold and two types of degumming agents, phosphoric acid and water were compared. The samples used were crude palm kernel oil and its fractions. The effects of bleaching earths and degumming agents on quality and composition of these oils were also investigated. SBE Gold earth had superior adsorptive cleansing capability when compared with the other bleaching earths. Results showed that phosphopric acid was a better degumming agent compared to water. It was found that the optimum temperature and dosage of clay for the bleaching of palm kernel products were at 95°C and 0.5% respectively.

Oil palm lignocellulose biomass utilization : Novel value-added products

Oil palm produces a large amount of lignocellulose biomass. The exploitation of this biomass is still traditional and low, i.e., for fibre production, organic fertilizer (for soil amelioration, structure and fertility improvement) and erosion prevention. Although these are environmentally friendly practices, there is little value addition, thereby prompting a need to increase the quantum of […]
