Determination Of Myristic Acid Peroxide Numbers (C1499) From The Fractionation Unit At PT SOCI Medan

Determining Peroxide Numbers: A Crucial Step in Ensuring Product Quality

Introduction

In the world of food and cosmetics, the quality of products is of utmost importance. One of the key factors that determine the quality of these products is the level of oxidation, which can be measured by determining the peroxide number. In this article, we will discuss the method of determining peroxide numbers from myristic acid (C1499) conducted at PT SOCI Medan, a leading manufacturer of high-quality products.

Understanding Peroxide Numbers

Peroxide numbers are indexes that indicate the amount of fat or oil that has been oxidized. In simple terms, it measures the level of rancidity in a product. The higher the peroxide number, the higher the level of oxidation, and therefore, the lower the quality of the product. On the other hand, a low peroxide number indicates that the product has good stability and does not experience significant oxidation.

The Importance of Determining Peroxide Numbers

Determining peroxide numbers is a crucial step in ensuring product quality, especially in the food and cosmetics industry. Oxidation can cause a decrease in quality and affect product safety, so that periodic monitoring of peroxide numbers is highly recommended. With a standardized procedure like this, PT SOCI Medan can maintain the quality of its products and ensure that the resulting myristic acid meets the expected standards.

The Method of Determining Peroxide Numbers

To determine the peroxide number of C1499 products, a mixture of acetone and chloroform is prepared in a ratio of 3:2. The gas nitrogen is then flowed into the system for 2 minutes to replace the air in the Erlenmeyer flask. This step is very important to prevent further oxidation, which can affect the measurement results.

After the air replacement process, 1 ml of saturated potassium iodide solution (KI) is added to the mixture. Next, the mixture is shaken for 1 minute and left in a dark room for 5 minutes. This process aims to ensure that the chemical reaction between the potassium iodide and the product can take place optimally without light interference.

After the specified time, 200 ml of distilled water is added to the mixture. Furthermore, titration is carried out using sodium thiosulfate solution (Na2S2O3) with a concentration of 0.01 N until the color of the solution turns pale yellow. At this stage, starch is added as an indicator until the solution turns black purple. The titration process is continued by re-adding sodium thiosulfate until the solution becomes clear.

The Result of the Analysis

The final result of this analysis is the determination of peroxide numbers that indicate the oxidation level of myristic acid. In testing conducted at PT SOCI Medan, the value of the peroxide number found was 1 mg of EQ. The determination of this low peroxide number shows that myristic acid (C1499) has good stability and does not experience significant oxidation.

The Significance of Low Peroxide Numbers

Further analysis shows that the low peroxide number value is very important to ensure product quality, especially in the food and cosmetics industry. Oxidation can cause a decrease in quality and affect product safety, so that periodic monitoring of peroxide numbers is highly recommended. With a standardized procedure like this, PT SOCI Medan can maintain the quality of its products and ensure that the resulting myristic acid meets the expected standards.

Conclusion

In conclusion, determining peroxide numbers is a crucial step in ensuring product quality, especially in the food and cosmetics industry. The method of determining peroxide numbers involves a systematic process that ensures the accuracy of measurement results. With a standardized procedure like this, PT SOCI Medan can maintain the quality of its products and ensure that the resulting myristic acid meets the expected standards.

Recommendations

Based on the analysis conducted at PT SOCI Medan, it is recommended that periodic monitoring of peroxide numbers be carried out to ensure product quality. This can be achieved by implementing a standardized procedure like the one discussed in this article. Additionally, it is recommended that professionals in the field of quality analysis and product quality control be trained on the method of determining peroxide numbers to ensure that they can carry out the analysis accurately and efficiently.

Future Directions

Future research can focus on developing new methods for determining peroxide numbers that are more accurate and efficient. Additionally, research can be conducted to investigate the effects of oxidation on product quality and safety. By understanding the effects of oxidation, manufacturers can take steps to prevent it and ensure that their products meet the expected standards.
