Unlocking the Secrets of Palm Oil: A Comprehensive Study on Oil Extraction and Total Blood Cholesterol Testing in Mice

Introduction

Palm oil, derived from the mesocarp of the oil palm tree (Elaeis guineensis Jacq.), is a widely used raw material in the food industry, particularly as a cooking oil. However, the purification process involved in this oil often results in a decrease in its nutritional content. This study aims to explore the effect of giving red palm oil on total blood cholesterol levels in mice, providing a clearer picture of its potential health benefits compared to other cooking oils, such as olive oil.

Research Purposes

The primary objective of this study is to determine the effect of red palm oil on total blood cholesterol levels. By understanding this relationship, it is expected to provide valuable insights into the potential health benefits of red palm oil, which can be used to inform dietary recommendations and guide further research in this area.

Research Methods

The research process begins with the extraction of oil from oil palm flesh, where the oil produced is then purified to produce red palm oil. Several oil parameters are tested, including free fatty acids, fatty acid compositions, vitamin E, scalen, and carotenoids. In addition, total blood cholesterol testing is conducted by giving red palm oil and olive oil at a dose of 25 g/kg body weight (0.6 ml) and 50 g/kg body weight (1.2 ml) to mice every day for 4 weeks. In the fifth week, administration of simvastatin is done to determine the additional effects on cholesterol levels. Every week, mouse blood samples are examined using a cholesterol test, and the data obtained are analyzed using the SPSS program with the Kruskal-Wallis and Anava One-way test.

Research Results

Oil extraction from palm flesh produces a yield of 21.63%. The analysis shows that the content of vitamin E in red palm oil is much higher than olive oil, with a value of around 765 μg/ml for palm oil and 78.50 μg/ml for olive oil. Likewise, carotenoid content in red palm oil reaches 546 μg/ml, while olive oil is only 16 μg/ml. However, the Skugene content in red palm oil is lower (246.66 mg/L) compared to olive oil (1761.35 mg/L). Analysis of fatty acids shows that palm oil and olive oil have different free fatty acid values, respectively 2.99% and 0.483%. In the composition of fatty acids, palm oil has a percentage of saturated and unsaturated fatty acids of 48.9087% and 50.8535%, while olive oil has a percentage of 13,8914% and 86,1086%.

Total Blood Cholesterol Testing

Testing of total blood cholesterol does not show a significant difference (P> 0.05) between the control group and treatment, so there is no striking difference in the total decrease in blood cholesterol in rats of all samples tested.

Conclusion

Based on this study, it can be concluded that there is no significant difference in decreasing the total blood cholesterol of each sample, both red palm oil and olive oil. This finding provides an important insight into the composition and health benefits of red palm oil, although its effectiveness in reducing blood cholesterol in this study has not been proven significantly. Therefore, further research is needed to explore the potential health benefits of red palm oil and to understand more in its effect on heart health and cholesterol.

Implications of the Study

This study has several implications for the food industry and public health. Firstly, it highlights the importance of understanding the nutritional content of cooking oils and their potential health benefits. Secondly, it suggests that red palm oil may not be as effective in reducing blood cholesterol levels as previously thought. Finally, it emphasizes the need for further research to explore the potential health benefits of red palm oil and to understand more in its effect on heart health and cholesterol.

Future Directions

Future research should focus on exploring the potential health benefits of red palm oil, particularly its effect on heart health and cholesterol. This can be achieved through a series of studies that investigate the effects of red palm oil on different biomarkers of cardiovascular disease, such as blood pressure, triglycerides, and LDL cholesterol. Additionally, studies should be conducted to investigate the effects of red palm oil on different populations, such as healthy individuals, individuals with cardiovascular disease, and individuals with high cholesterol levels.

Limitations of the Study

This study has several limitations that should be acknowledged. Firstly, the sample size was relatively small, which may have limited the statistical power of the study. Secondly, the study only investigated the effects of red palm oil on total blood cholesterol levels, and did not investigate its effects on other biomarkers of cardiovascular disease. Finally, the study only used a single dose of red palm oil, and did not investigate the effects of different doses on blood cholesterol levels.

Conclusion

In conclusion, this study provides valuable insights into the composition and health benefits of red palm oil. While it did not show a significant difference in decreasing the total blood cholesterol of each sample, it highlights the importance of understanding the nutritional content of cooking oils and their potential health benefits. Further research is needed to explore the potential health benefits of red palm oil and to understand more in its effect on heart health and cholesterol.
