Determination of Water Content and Free Fatty Acid Content in Crude Palm Stearin (CPS) and Refined Bleached Deodorized Palm Stearin (RBDPS)

Introduction

The palm oil industry is one of the largest and most significant contributors to the global economy, with palm oil being a crucial component in various products, including food, cosmetics, and pharmaceuticals. Crude Palm Stearin (CPS) and Refined Bleached Deodorized Palm Stearin (RBDPS) are two types of palm oil products that are widely used in various applications. However, the quality of these products is crucial in determining their stability, shelf life, and overall performance. In this study, we aim to determine the water content and free fatty acid content in CPS and RBDPS from several regions, including Rantauprapat, Dumai, and Lampung.

Methodology

The determination of water content in CPS and RBDPS was carried out using the gravimetric method, while the free fatty acid content was measured using the alkalimetric titration method with a standard solution of 0.0948 N. The analysis was conducted on samples from Rantauprapat, Dumai, and Lampung, and the results were compared to the Meoma and Poam quality standards.

Results

The results of the analysis show that the water content in CPS for the Rantauprapat area is 0.124%, Dumai 0.113%, and Lampung 0.127%. In contrast, the water content in RBDPS is 0.113% by weight for Rantauprapat, 0.104% by weight for Dumai, and 0.096% by weight for Lampung. The free fatty acid levels in CPS for Rantauprapat are 3.511%, Dumai 3.709% by weight, and Lampung 3.800% by weight. For RBDPS, the free fatty acid levels are 0.179% by weight in Rantauprapat, 0.154% by weight in Dumai, and 0.167% by weight in Lampung.

Analysis of Research Results

Water content and free fatty acid content are crucial parameters in determining the quality of palm oil products, including CPS and RBDPS. Water content that is too high can affect the stability and shelf life of the product, while high free fatty acid content can be an indication of oil damage due to oxidation or hydrolysis processes. In this study, the water content found in CPS and RBDPS is within a safe limit, but it needs attention to keep this level from increasing, especially during storage and transportation.

Conversely, free fatty acid levels in CPS indicate a higher number than RBDPS, which may be caused by an ineffective purification process in CPS. A good refining process can reduce the amount of free fatty acids, thereby increasing the quality and selling value of RBDPS. Overall, the results of this study provide a clear picture of the quality of CPS and RBDPS from several regions.

Conclusion

The determination of water content and free fatty acid content in CPS and RBDPS is crucial in determining the quality of these products. The results of this study show that the water content in CPS and RBDPS is within a safe limit, but it needs attention to keep this level from increasing. The free fatty acid levels in CPS indicate a higher number than RBDPS, which may be caused by an ineffective purification process in CPS.

It is essential for producers and palm oil industry players to continue to monitor and control these parameters so that the products produced always meet the established quality standards. By paying attention to quality, the palm oil industry can increase competitiveness in the global market and provide greater economic benefits for farmers and producers.

Recommendations

Based on the results of this study, the following recommendations are made:

Continued monitoring and control of water content and free fatty acid levels: Producers and palm oil industry players should continue to monitor and control these parameters to ensure that the products produced meet the established quality standards.
Improvement of purification process: The purification process in CPS should be improved to reduce the amount of free fatty acids, thereby increasing the quality and selling value of RBDPS.
Implementation of quality control measures: Quality control measures should be implemented to ensure that the products produced meet the established quality standards.
Training and education: Training and education programs should be conducted to educate producers and palm oil industry players on the importance of quality control and the methods used to determine water content and free fatty acid levels.

Limitations of the Study

This study has several limitations, including:

Limited sample size: The sample size used in this study was limited, and further studies should be conducted to confirm the results.
Limited geographic scope: The study was conducted in only three regions, and further studies should be conducted to determine the water content and free fatty acid levels in other regions.
Limited analysis: The analysis was limited to only two parameters, water content and free fatty acid levels, and further studies should be conducted to determine other parameters that affect the quality of CPS and RBDPS.

Future Research Directions

Future research directions should include:

Determination of other parameters: Further studies should be conducted to determine other parameters that affect the quality of CPS and RBDPS, such as peroxide value, acid value, and saponification value.
Comparison of different refining processes: Further studies should be conducted to compare the effectiveness of different refining processes in reducing the amount of free fatty acids in CPS.
Implementation of quality control measures: Further studies should be conducted to determine the effectiveness of quality control measures in ensuring that the products produced meet the established quality standards.
