Factors that Influence the Release of Tin, Aluminum, and Zinc on Canned Drinks

Canned drinks have become a staple in many households due to their convenience and practicality. However, the safety of these drinks has been a topic of concern in recent years. The corrosion of canned drink packaging can lead to the release of harmful metals such as tin, aluminum, and zinc into the drinks. This corrosion is influenced by various factors, including the nature of the food itself, which is none other than the pH (degree of acidity) of drinks in cans. High acidic properties can increase the rate of corrosion in containers, leaving metal residues that can pollute drinks. In addition, other factors such as the remaining oxygen in packaging, the characteristics of packaging materials, and storage time also contribute to this process.

The Impact of Corrosion on Consumer Health

Corrosion in canned drink packaging can cause the release of metals such as tin, aluminum, and zinc. If the concentration of this metal exceeds the recommended maximum limit, it can have a negative impact on consumer health. The release of these metals can lead to various health problems, including gastrointestinal issues, kidney damage, and even cancer. Therefore, it is essential to understand the factors that influence the release of these metals to ensure the safety of canned drinks.

Research on pH and Expiration

A study was conducted to analyze the effect of pH and expiration on the release of tin, aluminum, and zinc on canned drinks. The study used the comparative causal method and atomic absorption spectrophotometer to measure metal content in carbonated cans, beer, and juice drinks originating from various markets, taking into account the expiration date of each product. The results showed a significant correlation between pH and metal release, with higher pH values resulting in lower metal content. The study also found that the longer the expiration period, the lower the metal content is released.

The results of the study are as follows:

Metal content in expired carbonation cans in 2014 was higher than in 2015.
Tin content in expired carbonated canned drinks in 2014 was recorded at 5,7676 mcg/ml, aluminum 0.0894 mcg/ml, and zinc 2,1545 mcg/ml.
Metal content in beer and juice in 2015 was much lower, with a value of 2,5000 mcg/ml each for tin, 0.0450 mcg/ml for aluminum, and 1,0785 mcg/ml for zinc.

Conclusion and Implications

From the results of the study, it can be concluded that the lower the pH value, the higher the release of tin, aluminum, and zinc in canned drinks. In addition, the longer the expiration period, the lower the metal content is released. The study also found that the measured tin level meets the standards set by SNI (2009) concerning the maximum limit of metal contamination in food. Likewise for aluminum and zinc, which meet the requirements of the Republic of Indonesia Minister of Health (2002) regarding the quality of drinking water.

Added Value for Consumers

For consumers, knowledge of the factors that influence the release of metals in canned drinks is very important. By understanding the relationship between pH, expiration, and metal contamination, consumers can be more careful in choosing products that are safe for consumption. Always check the expired label and choose a drink with a higher pH to minimize health risks due to metal contamination.

Overall, this research provides an important insight into the safety of canned drink packaging and the need for awareness from producers to maintain the quality of the products they offer. The study highlights the importance of monitoring pH levels and expiration dates to ensure the safety of canned drinks.

Future Research Directions

Future research should focus on investigating the effects of other factors that influence the release of metals in canned drinks, such as the characteristics of packaging materials and storage time. Additionally, studies should be conducted to determine the long-term effects of metal contamination on consumer health. By understanding the factors that influence metal release, producers can take steps to minimize contamination and ensure the safety of their products.

Recommendations for Producers

Producers of canned drinks should take the following steps to minimize metal contamination:

Monitor pH levels and expiration dates to ensure the safety of their products.
Use high-quality packaging materials that are resistant to corrosion.
Store products in a cool, dry place to minimize the risk of metal contamination.
Conduct regular testing to ensure that metal levels meet the recommended maximum limits.

By following these recommendations, producers can ensure the safety of their products and minimize the risk of metal contamination. The safety of canned drinks is a shared responsibility between producers, consumers, and regulatory agencies.

Conclusion

In conclusion, the release of tin, aluminum, and zinc on canned drinks is influenced by various factors, including pH, expiration, and packaging materials. Understanding the relationship between these factors is essential to ensuring the safety of canned drinks. This research provides an important insight into the safety of canned drink packaging and highlights the need for awareness from producers to maintain the quality of their products. By working together, we can ensure the safety of canned drinks and protect consumer health.
