A review on food processing and preparation methods for altering fish allergenicity

Area of Science:

• Food science
• Immunology
• Allergology

Background:

• Fish is a common food allergen, causing immune system overreactions.
• Food processing can modify the allergenic potential of proteins.
• Not all processing methods eliminate the risk of fish protein allergy.

Purpose of the Study:

• To review the impact of thermal and non-thermal fish processing on allergenicity.
• To explore structural modifications that affect fish allergen stability.
• To understand fish allergy prevalence, mechanisms, and allergen cross-reactivity.

Main Methods:

• Review of current literature on fish processing and allergy.
• Analysis of protein conformational changes due to processing.
• Examination of IgE epitopes and cross-reactivity patterns.

Main Results:

• Processing methods can significantly alter fish protein allergenicity.
• Structural modifications influence the stability of fish allergens.
• Varied effects of different processing techniques on allergenicity observed.

Conclusions:

• Understanding fish processing effects on allergenicity is vital for consumer safety.
• Further research is needed to fully characterize allergen stability post-processing.
• Managing fish allergy requires knowledge of processing impacts on different species.
