Safety and Regulatory Aspects

Food additives and preservatives are regulated by agencies such as:

• U.S. Food and Drug Administration (FDA)
• European Food Safety Authority (EFSA)
• Joint FAO/WHO Expert Committee on Food Additives (JECFA)

Key safety measures include:

• Establishing acceptable daily intake (ADI) levels
• Mandating clear labeling on food packaging
• Conducting toxicity and long-term exposure studies

Consumer Concerns and Trends

Growing health awareness has led to increased demand for:

• Natural preservatives (e.g., citrus extracts, fermentation products)
• Clean-label foods (minimal synthetic additives)
• Reduced use of nitrites in processed meats

Conclusion

Food additives and preservatives are essential for food safety and quality but must be used responsibly. Regulatory oversight and consumer education help balance benefits and potential risks. Future trends favor natural alternatives and transparency in food labeling to meet health-conscious demands.
