Description
Summary:Cellulose nanofiber (CNF) based on lignocellulosic oil palm empty fruit bunches (OPEFB) shows its potential as a stabilizer in multiphase systems because of its large specific surface area. This study aims to isolate CNF from OPEFB and its application as a particle stabilizer for pickering emulsion. OPEFB was isolated mechanically using an ultrafine grinding-ultrasonication combination process. Ultrasonication lasts 30-60 minutes with a frequency of 20 kHz and an amplitude of 80%. Furthermore, 0.5% (w/v) CNF was optimized as oil and water (o/w) emulsion particle stabilizer. The results showed that CNF with ultrasonication treatment for 60 minutes had a diameter of 54.80 ± 0.85 nm, a degree of crystallinity of 66.75%, and a potential zeta value of -40.77 ± 1.05 mV. The emulsification process with a combination of ultra turrax homogenization at 9,500 rpm and ultrasonication resulted in 7.78 ± 0.71 µm emulsion droplets which were stable against coalescence and Ostwal ripening. In general, this study provides basic knowledge about the appropriate method for the emulsification process of picking emulsions using CNF particles isolated from OPEFB. In conclusion, nano-sized cellulose particles based on palm oil mill industrial waste can be applied as a high-value-added biomaterial for eco-friendly emulsion pickering stabilizer particles.
