Adsorpsi Asam Lemak Bebas Dalam Minyak Sawit Mentah Menggunakan Adsorben Abu Tandan Kosong Sawit

Abstract

Research on the use of the oil palm empty fruit bunch (OPEFB) as an adsorbent for free fatty acid (FFA) adsorption on Crude Palm Oil (CPO) has been done. CPO is the main raw material in the manufacture of food products. The results of OPEFB adsorbent characteristics showed the amount of water content and ash content of 0,067% and 0,175%, XRF analysis obtained the greatest content of OPEFB in the form potassium metal as much as 44,24%, FTIR analysis identified that there were CO3 compounds in wave number 1648 cm-1 and SEM analysis indicates there are no pores in OPEFB. The result showed that the number of OPEFB with the best adsorption was 0,1 gram with 60 minute optimum contact time. The CPO adsorption process with OPEFB shows the Langmuir model with a correlation value (R2) of 0,8845 and the adsorptions kinetics follows the pseudo order 2 adsorption kinetics model with a correlation value (R2) of 0,9857. The results of this study showed the characteristics of CPO before and after adsorbed using 0,1 g of adsorbent OPEFB showed the amount of FFA level of 7,321% to 6,297%, water content of 0,0025% to 0,00119% and impurities content of 0,8847% to 0,8408%.

Use of Bentonite Adsorbent from Ujong Pacu for the Adsorption Free Fatty Acids from Crude Palm Oil

“…Specifically, these high levels can induce rancidity, resulting in an undesirable taste, discoloration, and a reduction in oil output. In order to mitigate the levels of free fatty acids (FFA), it is imperative to implement preventative measures at the earliest stages of the production process, starting from the harvesting phase and continuing through the storing phase prior to marketing (Syahwandi et al, 2019).…”

“…Subsequently, the adsorption process of free fatty acids (FFA) was conducted at a temperature of 70 oC for a duration of 4 hours. The levels of free fatty acids were then monitored at 30-minute intervals using the titration of acid-base using a secondary solution of NaOH 0.1 N (Syahwandi et al, 2019). 4.…”

“…In a separate investigation conducted by Syahwandi et al (2019), it was shown that the utilization of ATKS ash as an adsorbent material demonstrated the ability to adsorb free fatty acids (FFAs) from crude palm oil (CPO). The study determined that an optimal adsorbent mass of 0.1 g, along with a 60-minute adsorption duration, resulted in a reduction of FFA levels from 7.321% to 6.297% (Samantaray et al, 2022).…”
