Determination of Crude Palm Kernel Oil Quality obtained from the results of palm kernel extraction with N-HEXAN solvents at PT Palmcoco Laboratories

Introduction

The palm kernel oil industry is a significant contributor to the economy of Indonesia, with PT Palmcoco Laboratories playing a crucial role in the production of high-quality crude palm kernel oil (CPKO). The quality of CPKO is determined by various factors, including the method of extraction used, the concentration of free fatty acids, levels of impurities, humidity, and iodine values. In this study, we analyzed the quality of CPKO obtained from the results of palm kernel extraction with N-HEXAN solvents at PT Palmcoco Laboratories.

Background

Palm kernel oil is a crude oil extracted from palm kernel, which contains various components such as fat, protein, fiber, and water. The quality of CPKO is influenced by the concentration of free fatty acids, levels of impurities, humidity, and iodine values. The analysis of CPKO quality is essential to ensure that the oil produced meets the necessary standards for further use in various industries.

Methodology

The analysis of CPKO quality was conducted at PT Palmcoco Laboratories from 19 to 29 January 2009. The oil content in the sample tested was recorded at 41.86%, 42.10%, and 42.07%. Meanwhile, the concentration of free fatty acids (FFA) for the sample is 4.50%, 4.54%, and 4.50%. The iodine values obtained are 17.62%, 17.34%, and 17.78%, while the humidity content is at 0.31%, 0.42%, and 0.38%. Finally, the detected dirt content is 0.005%, 0.003%, and 0.004%.

CPKO Quality Analysis

The quality of CPKO is strongly influenced by various factors, including the method of extraction used. The process of extraction with N-Hexan is an effective method for obtaining oil from palm kernel because it can separate unwanted components and increase oil yields. Using organic solvents such as N-Hexan also contributes in reducing water and dirt content in the final product.

The lower free fatty acid concentration in CPKO is very desirable because it reflects the level of oil resistance to rancid. The level of free fatty acids above 5% can show that oil has experienced degradation, while levels below 5% are still acceptable for industrial needs. In the sample tested, FFA levels ranged from 4.50% to 4.54%, which indicated that the oil was still in good condition.

Iodine value is another important indicator in assessing oil quality. This value reflects the amount of double bonds in fatty acids in oil. The higher the iodine value, the higher the content of unsaturated fatty acids that indicate the quality and stability of oil. The iodine value in the CPKO sample shows that the oil produced has a good balance between saturated and unsaturated fatty acids.

Humidity and dirt content are also key parameters in determining the quality of CPKO. High humidity can cause the fermentation process and decrease in quality, while low levels of dirt are very important for maintaining the purity of oil. All analysis results show that the CPKO resulting from the extraction process at PT Palmcoco Laboratories is in a safe range and meets the necessary standards.

Conclusion

From the results of the analysis conducted, it can be concluded that the quality of the crude palm kernel oil obtained through extraction with the N-Hexan solvent at PT Palmcoco Laboratories shows satisfying results and meets the established quality standards. This quality determination is important to ensure that the CPKO produced is not only economically beneficial, but also meets the security and quality aspects for further use in various industries. The selection of appropriate extraction methods, as well as attention to quality parameters, will contribute to the success of the palm oil industry in Indonesia.
