Determination Of Water Content And Free Fatty Acid Content In Canola Oil And Cooking Oil Circulating In Kec. Medan Selayang

by ADMIN 124 views

Introduction

The quality of cooking oil is a crucial factor in determining the taste, aroma, and nutritional value of food. Canola oil and cooking oil are two of the most widely used oils in cooking, but their quality can vary significantly depending on several factors, including water content and free fatty acid levels. In this study, we aimed to determine the water content and free fatty acid levels in canola oil and cooking oil circulating in Kec. Medan Selayang, a district in Medan, Indonesia. The method used for this determination is the alkaline metric titration, which has been standardized in SNI 374-1995.

Methodology

The alkaline metric titration method is a widely used technique for determining the water content and free fatty acid levels in oils. This method involves the reaction of the oil with an alkaline solution, resulting in the formation of a soap-like substance. The amount of alkaline solution required to react with the oil is directly proportional to the water content and free fatty acid levels in the oil. The results of this study were compared with the standards set by SNI 374-1995.

Results

The results of this study showed that the water content in canola oil was 0.028%, which is lower than Sania cooking oil (0.093%), Sunco cooking oil (0.079%), and Bimoli oil (0.078%). Meanwhile, free fatty acid levels in canola oil were recorded at 0.061%, which is higher compared to Sania cooking oil (0.067%), Sunco cooking oil (0.056%), and Bimoli oil (0.062%). These results indicate that canola oil has a lower water content than some other cooking oils, but higher free fatty acid levels.

Discussion

High water content in cooking oil can affect the quality and storage power of the product. Moisture in oil can cause rancidity or decay process, thereby reducing taste and aroma. Meanwhile, high levels of free fatty acids indicate the presence of oil degradation, which can be caused by a recurring heating process or inappropriate storage. The results of this study indicate that consumers need to be more careful in choosing oil, and need to pay attention to how to store and use to maintain the quality of oil used.

Interestingly, the results of this study also indicate that although canola oil has a lower water content than some other cooking oils, free fatty acid levels are actually higher. This shows that consumers need to be more careful in choosing oil, and need to pay attention to how to store and use to maintain the quality of oil used. In addition, it is also important to pay attention to labels and product information when buying cooking oil. By understanding these parameters, consumers can make better decisions, both in terms of health and product quality used for cooking.

Conclusion

In conclusion, this study provides a clear picture of the quality of oil circulating in the Medan Selayang District Market. The results of this study indicate that canola oil has a lower water content than some other cooking oils, but higher free fatty acid levels. This shows that consumers need to be more careful in choosing oil, and need to pay attention to how to store and use to maintain the quality of oil used. It is hoped that this information can be useful for the community in choosing safe and quality products for daily needs.

Recommendations

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

  • Consumers should be more careful in choosing oil, and need to pay attention to how to store and use to maintain the quality of oil used.
  • Labels and product information should be carefully checked when buying cooking oil.
  • The quality of oil should be regularly monitored to ensure that it meets the standards set by SNI 374-1995.
  • Further research should be conducted to determine the effects of water content and free fatty acid levels on the nutritional value and taste of food.

Limitations

This study has several limitations, including:

  • The sample size was limited to four types of cooking oil.
  • The study only focused on water content and free fatty acid levels, and did not consider other parameters that may affect the quality of oil.
  • The study was conducted in a single district, and may not be representative of other areas.

Future Research Directions

Future research should focus on the following areas:

  • Determining the effects of water content and free fatty acid levels on the nutritional value and taste of food.
  • Conducting a larger-scale study to determine the quality of oil circulating in different areas.
  • Developing a more comprehensive method for determining the quality of oil.

Q: What is the importance of determining water content and free fatty acid levels in cooking oil?

A: Determining water content and free fatty acid levels in cooking oil is crucial because high water content can cause rancidity or decay process, thereby reducing taste and aroma, while high levels of free fatty acids indicate the presence of oil degradation, which can be caused by a recurring heating process or inappropriate storage.

Q: What is the method used for determining water content and free fatty acid levels in cooking oil?

A: The alkaline metric titration method is a widely used technique for determining the water content and free fatty acid levels in oils. This method involves the reaction of the oil with an alkaline solution, resulting in the formation of a soap-like substance. The amount of alkaline solution required to react with the oil is directly proportional to the water content and free fatty acid levels in the oil.

Q: What are the results of the study on the water content and free fatty acid levels in canola oil and cooking oil?

A: The results of the study showed that the water content in canola oil was 0.028%, which is lower than Sania cooking oil (0.093%), Sunco cooking oil (0.079%), and Bimoli oil (0.078%).
