Determination of Phosphorus Levels in Crude Palm Oil (CPO) and Refined Bleached Deodorized Palm Olein (RBDPO) using UV-Visible Spectrophotometry

Introduction

The palm oil industry is one of the largest and most significant contributors to the global economy, with millions of people relying on it for their livelihood. However, the quality of palm oil products is a major concern, as it can affect not only the health of consumers but also the reputation of the industry as a whole. One of the key factors that determine the quality of palm oil is the level of phosphorus present in it. Phosphorus is a naturally occurring element that can be found in small amounts in palm oil, but excessive levels can be detrimental to human health. Therefore, it is essential to determine the levels of phosphorus in crude palm oil (CPO) and refined bleached deodorized palm olein (RBDPO) to ensure that they are within safe limits.

Research Methodology

To determine the levels of phosphorus in CPO and RBDPO, a research study was conducted at PT. Sinarmas Tbk Medan-Belawan. The study used UV-Visible spectrophotometry, a technique that involves the use of a device that measures the absorption of light by a sample. This technique is widely used in various industries, including the food and beverage industry, to analyze the quality of products.

The first step in the analysis process was to acidify the sample with HCl, which is a strong acid that helps to break down the sample and prepare it for analysis. After acidification, the sample was heated in a furnace at 600 ° C to remove any disturbing substances that could affect the accuracy of the measurement.

UV-Visible Spectrophotometry

UV-Visible spectrophotometry is a technique that works based on the principle that each substance has a unique absorption spectrum. By analyzing this spectrum, the levels of phosphorus in the sample can be determined accurately. The device used in this study was a UV-Visible spectrophotometer, which is a sophisticated instrument that can measure the absorption of light by a sample over a wide range of wavelengths.

Results and Discussion

The results of the study showed that the levels of phosphorus in CPO ranged from 12,6186 ppm to 15,8871 ppm, while the levels of phosphorus in RBDPO ranged from 1,3939 ppm to 3,8906 ppm. These figures indicate that the levels of phosphorus in both CPO and RBDPO are within safe limits, which is a maximum of 30 ppm for CPO and 5 ppm for RBDPO.

The results of the study also showed that the levels of phosphorus in CPO varied, but remained below the specified maximum limit. This suggests that the palm oil product is safe for consumption. Meanwhile, the levels of phosphorus in RBDPO also showed positive results, far below the maximum allowable limit.

Conclusion

In conclusion, this study shows that the levels of phosphorus in CPO and RBDPO produced by PT. Sinarmas Tbk Medan-Belawan are still within a safe limit. The use of UV-Visible spectrophotometry methods in this study provided high accuracy and useful information for the palm oil industry to ensure the quality of their products. Maintained phosphorus levels are not only important for compliance with standards but also to maintain consumer health.

Recommendations

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

The palm oil industry should continue to use UV-Visible spectrophotometry to analyze the levels of phosphorus in their products.
The industry should also implement quality control measures to ensure that the levels of phosphorus in their products are within safe limits.
Consumers should be aware of the importance of maintaining safe levels of phosphorus in palm oil products and should choose products that are certified to be within safe limits.

Limitations of the Study

This study has several limitations, including:

The study was conducted on a small sample size, which may not be representative of the entire population.
The study only analyzed the levels of phosphorus in CPO and RBDPO, and did not consider other factors that may affect the quality of palm oil products.
The study did not consider the impact of phosphorus levels on human health, which is an important consideration in the production and consumption of palm oil products.

Future Research Directions

Future research should focus on the following areas:

Conducting a larger-scale study to analyze the levels of phosphorus in CPO and RBDPO.
Considering other factors that may affect the quality of palm oil products, such as the levels of other elements and the presence of contaminants.
Investigating the impact of phosphorus levels on human health and developing strategies to minimize the risks associated with excessive phosphorus levels in palm oil products.
