Introduction

Tauco, a fermented soybean product, is a staple food in many parts of Indonesia, including the city of Medan. The production of tauco involves a process of fermentation that can result in a semi-solid or runny texture, with varying colors ranging from vaginal discharge to blackish brown. One of the additional ingredients commonly used in making tauco is sodium benzoate, a preservative that helps extend the shelf life of food. However, excessive consumption of sodium benzoate can lead to various side effects, including stomach cramps, numbness in the mouth, stomach irritation, and potential allergic reactions and neurological problems.

The use of sodium benzoate in tauco has raised concerns among consumers and health experts, particularly in the city of Medan, where traditional markets and supermarkets sell a wide range of tauco products. This study aims to analyze the existence and level of sodium benzoate in bulk tauco and packaging sold in several traditional markets and supermarkets in the city of Medan in 2013. The research methodology employed a descriptive survey, with a sampling of 10 items, consisting of 5 bulk tauco and 5 packaging tauco. All samples were analyzed at the North Sumatra Provincial Health Laboratory Center.

Methodology

The study employed a descriptive survey methodology, which involved collecting data on the levels of sodium benzoate in bulk tauco and packaging sold in traditional markets and supermarkets in the city of Medan. A total of 10 samples were collected, consisting of 5 bulk tauco and 5 packaging tauco. The samples were then analyzed at the North Sumatra Provincial Health Laboratory Center using standard laboratory procedures.

The sampling frame consisted of 5 traditional markets and 5 supermarkets in the city of Medan. The selection of samples was based on a random sampling method, with an equal number of bulk tauco and packaging tauco samples collected from each market and supermarket.

Results

The results of the study showed that the highest levels of sodium benzoate were found in the packaging tauco with the J2 sample code, which was 0.432 g/kg. Conversely, the lowest levels were found in bulk tauco with the C1 sample code, which was only 0.054 g/kg. These findings indicate that there are significant differences in the level of sodium benzoate between the samples.

However, it is worth noting that all of the samples analyzed in this study still meet the health requirements for human consumption, as stipulated in the Minister of Health Regulation No. 722/Menkes/Per/IX/88 concerning Food Additives. This regulation sets a maximum limit of 0.5 g/kg for the use of sodium benzoate in food products.

Discussion

The results of this study have several implications for the food industry and consumers. Firstly, the findings suggest that food producers should be more transparent about the ingredients used in their products, including the levels of sodium benzoate. This is essential to provide consumers with adequate information to make informed choices about the food they consume.

Secondly, consumers should be more careful in choosing food products, particularly those containing preservatives like sodium benzoate. This is because excessive consumption of sodium benzoate can lead to various side effects, including stomach cramps, numbness in the mouth, stomach irritation, and potential allergic reactions and neurological problems.

Conclusion

The results of this study have several implications for the food industry and consumers. Food producers should be more transparent about the ingredients used in their products, and consumers should be more careful in choosing food products, particularly those containing preservatives like sodium benzoate.

Recommendations

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

Food producers should be more transparent about the ingredients used in their products, including the levels of sodium benzoate.
Consumers should be more careful in choosing food products, particularly those containing preservatives like sodium benzoate.
The government should continue to monitor the use of sodium benzoate in food products and ensure that food producers comply with the regulations set by the Minister of Health.
Consumers should be educated about the potential side effects of excessive consumption of sodium benzoate and the importance of choosing food products that are free from preservatives.

Limitations

This study has several limitations, including:

The sampling frame consisted of only 5 traditional markets and 5 supermarkets in the city of Medan, which may not be representative of the entire city.
The study only analyzed the levels of sodium benzoate in bulk tauco and packaging sold in traditional markets and supermarkets, and did not examine the levels of sodium benzoate in other food products.
The study did not examine the potential side effects of excessive consumption of sodium benzoate in humans.

Future Research Directions

Future research should focus on the following areas:

Conducting a more comprehensive study on the use of sodium benzoate in food products sold in traditional markets and supermarkets in the city of Medan.
Examining the levels of sodium benzoate in other food products, such as instant noodles and processed meats.
Investigating the potential side effects of excessive consumption of sodium benzoate in humans.

Conclusion

In conclusion, this study provides a clear picture of the use of sodium benzoate in bulk tauco and packaging sold in several traditional markets and supermarkets in the city of Medan in 2013. The findings suggest that there are significant differences in the level of sodium benzoate between the samples, but all of the samples still meet the health requirements for human consumption. The results of this study have several implications for the food industry and consumers, and highlight the need for more transparency and education about the use of preservatives in food products.

Q: What is sodium benzoate?

A: Sodium benzoate is a preservative commonly used in food products, including tauco, to extend their shelf life. It is a synthetic compound that is used to prevent the growth of bacteria, yeast, and mold in food.

Q: What are the potential side effects of excessive consumption of sodium benzoate?

A: Excessive consumption of sodium benzoate can lead to various side effects, including stomach cramps, numbness in the mouth, stomach irritation, and potential allergic reactions and neurological problems.

Q: How much sodium benzoate is safe to consume?

A: The safe level of sodium benzoate consumption varies depending on the individual and the specific product. However, the Minister of Health Regulation No. 722/Menkes/Per/IX/88 sets a maximum limit of 0.5 g/kg for the use of sodium benzoate in food products.

Q: Can I still consume tauco if it contains sodium benzoate?
