Determining the Quality of Palm Kernel Oil: A Study on Acid Numbers and Saponification Numbers in Lauric Acid Hydrolysis at PT. Socimas Medan

Introduction

In the world of industrial vegetable oil processing, the determination of acid numbers and saponification numbers is a crucial step in ensuring the quality of the final product. At PT. Socimas Medan, a leading oil processing company in Indonesia, a thorough analysis was conducted to determine the acid numbers and saponification numbers from lauric acid obtained through the hydrolysis process of palm kernel oil (PKO). This study aims to provide an in-depth understanding of the importance of acid numbers and saponification numbers, the analysis methodology used, and the conclusions drawn from the results.

The Importance of Acid Numbers and Saponification Numbers

Acid numbers are a measure of the number of free fatty acids found in an oil. The higher the acid number, the more free fatty acids produced from the breakdown of triglycerides in oil, which can be caused by the process of oxidation or oil damage. On the other hand, the numbers of saponies indicate the amount of alkaline needed to sag a oil, which reflects the structure and composition of fatty acids in the oil. Acid numbers and consumption are very important in determining the quality of oil used, especially in the food and cosmetics industry. These values can affect the physical and chemical properties of the final product, as well as the shelf life and safety of consumption.

Acid numbers are a critical parameter in the quality control of vegetable oils. A high acid number can indicate the presence of free fatty acids, which can affect the flavor, texture, and stability of the oil. In contrast, a low acid number can indicate the presence of high-quality oil with minimal free fatty acids. Saponification numbers, on the other hand, are a measure of the amount of alkaline needed to saponify an oil. This value can provide information on the structure and composition of fatty acids in the oil.

Analysis Methodology

In the analysis conducted at PT. Socimas, the method used to determine the acid numbers and saponification numbers followed the applicable standards. Sampling was carried out carefully to ensure that the sample represented the entire batch of the processed PKO. Furthermore, acid numbers were determined by the titration method using an alkaline solution, while the numbers were obtained through a reaction with an alkaline solution under certain conditions.

The titration method used to determine acid numbers involves the addition of a known amount of alkaline solution to a sample of oil until the pH reaches a certain value. The amount of alkaline solution used is directly proportional to the number of free fatty acids present in the oil. The saponification method, on the other hand, involves the reaction of an oil with an alkaline solution under certain conditions. The amount of alkaline solution used is directly proportional to the number of fatty acids present in the oil.

Results and Discussion

The results of the analysis showed that acid numbers reached 269.9, while the numbers were recorded at 270.8. These values are in accordance with established standards, namely 269-275 for acid numbers and 270-276 for the number of sponsors at PT. Socimas. The results indicate that the products produced by PT. Socimas have good quality and are in accordance with established standards.

The accurate determination of acid numbers and saponification numbers is not only important to ensure compliance with regulations but also to improve product quality and customer satisfaction. The results of this study demonstrate the importance of routine and quality analysis in maintaining the reputation of PT. Socimas as a high-quality oil producer.

Conclusion

In conclusion, the determination of acid numbers and saponification numbers is a critical step in ensuring the quality of palm kernel oil. The results of this study demonstrate the importance of acid numbers and saponification numbers in determining the quality of oil used, especially in the food and cosmetics industry. The accurate determination of these two parameters is essential to ensure compliance with regulations, improve product quality, and customer satisfaction.
