The Effect of the Duration of CPO Storage on Free Fatty Acid Content and Water Content in Storage Tanks at PTPN III PKS Sei Mangkei Trading

Introduction

Crude palm oil (CPO) is one of the most widely traded edible oils in the world, with Indonesia and Malaysia being the largest producers. The quality of CPO is crucial in determining its economic value and competitiveness in the global market. However, the storage of CPO can lead to a significant increase in free fatty acid content and water content, which can affect its quality and shelf life. This study aims to investigate the effect of the duration of CPO storage on free fatty acid content and water content in storage tanks at PTPN III PKS Sei Mangkei Trading.

Background

CPO is a complex mixture of triglycerides, free fatty acids, and other compounds. The free fatty acid content of CPO is an important parameter in determining its quality and shelf life. Free fatty acids can be formed through hydrolysis reactions, which occur due to the presence of water and lipase enzymes. The water content of CPO is also an important factor in determining its quality, as high water content can lead to unwanted fermentation processes, trigger the growth of microorganisms, and accelerate oil damage.

Methodology

The study was conducted at PTPN III PKS Sei Mangkei, where observations were made on the effect of the duration of CPO storage on free fatty acid content and water content in the storage tank. The analysis showed that free fatty acid content was initially recorded at 4.04% with a moisture content of 0.1%. From observations made for several days, there was a significant change in free fatty acid content and water content.

Results

The results of the study showed that free fatty acid levels increased gradually over the storage period. On the second day, free fatty acid levels increased by 0.15%, the third day increased again by 0.18%, and on the fourth day experienced a surge of 0.33%. On the other hand, water content also showed a similar increase trend. On the second day, the water content increased by 0.02%, followed by an increase of 0.04% on the third day, and on the fourth day recorded a peak of an increase of 0.008%.

Analysis of the Effect of Long Storage

Increased levels of free fatty acids during the CPO storage period can be caused by several factors, including hydrolysis reactions that occur due to water and lipase enzymes. When CPO is stored for a long time, especially if it is not done proper treatment, the water content in CPO can increase, which in turn will increase the activity of the lipase enzyme. This enzyme breaks triglycerides into free fatty acids and glycerol, causing an increase in levels of free fatty acids.

Increased water content is also a major concern. The high water content in CPO not only affects the quality of oil but can also cause an unwanted fermentation process, triggers the growth of microorganisms, and accelerates oil damage. Therefore, control of water content and free fatty acids becomes crucial in CPO storage to maintain its quality and economic value.

Implications for Storage Practices

From the results of this study, it is important for the management of CPO storage tanks at PTPN III PKS Sei Mangkei to implement better storage procedures. The steps that can be taken include minimizing storage time, maintaining optimal storage temperatures, and routine monitoring of water content and free fatty acids. In addition, the use of dehydration tools to reduce water content in CPO before storage can also help maintain overall oil quality.

Conclusion

The study highlights the importance of controlling free fatty acid content and water content in CPO storage tanks. The results of the study show that increased levels of free fatty acids and water content can occur during the storage period, which can affect the quality and shelf life of CPO. Therefore, it is essential to implement better storage procedures, including minimizing storage time, maintaining optimal storage temperatures, and routine monitoring of water content and free fatty acids.

Recommendations

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

Minimize storage time to prevent the formation of free fatty acids and water content.
Maintain optimal storage temperatures to prevent the growth of microorganisms and unwanted fermentation processes.
Routine monitoring of water content and free fatty acids to ensure that the quality of CPO is maintained.
Use dehydration tools to reduce water content in CPO before storage.
Implement better storage procedures, including proper treatment and handling of CPO, to maintain its quality and economic value.

Future Research Directions

This study provides a comprehensive understanding of the effect of the duration of CPO storage on free fatty acid content and water content in storage tanks. However, there are still many areas that require further research, including:

Investigating the effect of different storage temperatures on free fatty acid content and water content.
Studying the effect of different storage times on free fatty acid content and water content.
Investigating the use of different dehydration tools to reduce water content in CPO before storage.
Developing new storage procedures and technologies to maintain the quality and shelf life of CPO.

Frequently Asked Questions (FAQs) about CPO Storage and Free Fatty Acid Content

Q: What is CPO storage and why is it important?

A: CPO storage refers to the process of storing crude palm oil (CPO) in tanks or containers for a period of time. CPO storage is important because it affects the quality and shelf life of the oil. Proper storage procedures can help maintain the quality of CPO, while improper storage can lead to the formation of free fatty acids and water content, which can affect the oil's quality and shelf life.

Q: What are free fatty acids and why are they a concern in CPO storage?

A: Free fatty acids are compounds that are formed through the hydrolysis of triglycerides in CPO. They can be formed due to the presence of water and lipase enzymes in the oil. Free fatty acids are a concern in CPO storage because they can affect the oil's quality and shelf life. High levels of free fatty acids can lead to the formation of off-flavors and off-odors, and can also affect the oil's texture and consistency.

Q: What is the ideal storage temperature for CPO?

A: The ideal storage temperature for CPO is between 10°C and 20°C (50°F and 68°F). This temperature range helps to slow down the formation of free fatty acids and water content, and can help maintain the quality of the oil.

Q: How often should CPO be monitored for free fatty acid content and water content?

A: CPO should be monitored regularly for free fatty acid content and water content. It is recommended to check the oil's quality at least once a week, and to take samples for analysis at regular intervals.
