Approaches for a more microbiologically and chemically safe dried fruit supply chain

Area of Science:

• Food Science
• Microbiology
• Food Safety

Background:

• Global dried fruit production has seen significant growth.
• Increased demand is driven by consumer preference for nutritious packaged foods and use in confectionery and bakery products.
• Contamination by pathogens and mycotoxins poses a significant risk to dried fruit safety.

Purpose of the Study:

• To highlight the limitations of current drying processes in ensuring microbial and chemical safety of dried fruits.
• To evaluate the potential of pre- and post-drying treatments as effective interventions.
• To identify strategies for optimizing dried fruit safety.

Main Methods:

• Review of existing literature on dried fruit production and contamination.
• Analysis of the efficacy of various drying, pre-drying, and post-drying treatments.
• Assessment of microbial and chemical hazard control strategies.

Main Results:

• Drying processes alone are insufficient to eliminate all microbial and chemical hazards.
• Pre- and post-drying treatments offer promising solutions for enhancing safety.
• Combined approaches, including drying with pre- and post-treatments, are effective for hazard control.

Conclusions:

• Optimizing interventions beyond the drying step is crucial for ensuring the microbial and chemical safety of dried fruits.
• Pre- and post-drying treatments are essential for mitigating risks associated with pathogenic bacteria, viruses, and mycotoxins.
• Further research and adoption of novel interventions are needed to protect the dried fruit supply chain.
