The development of high hydrostatic pressure processes as an alternative to other pathogen reduction methods

Area of Science:

• Biotechnology
• Food Science
• Pharmaceutical Science

Background:

• High hydrostatic pressure (HHP) is increasingly utilized in biological applications due to its low energy requirements and pathogen inactivation capabilities.
• HHP is explored as an alternative to conventional heat treatments for contaminant inactivation in diverse products.
• The application of HHP differs significantly between food products and pharmaceutical preparations, impacting process optimization.

Purpose of the Study:

• To review the application of high hydrostatic pressure (HHP) in biological contexts.
• To highlight the distinct considerations for optimizing HHP processes based on product type and intended use.
• To compare HHP process optimization for food products versus pharmaceutical preparations.

Main Methods:

• Literature review on high hydrostatic pressure (HHP) applications in biology.
• Analysis of HHP's impact on molecular structures, particularly proteins.
• Comparative assessment of HHP process objectives for different product categories.

Main Results:

• HHP is a viable alternative to heat treatments for pathogen reduction.
• Pharmaceutical preparations, containing pressure-sensitive proteins, require more complex HHP process optimization than foods.
• Product-specific factors and intended use critically influence HHP process design and evaluation.

Conclusions:

• While the fundamental principle of pathogen reduction via HHP is consistent, optimization strategies must be tailored.
• The sensitivity of molecular targets (e.g., proteins in pharmaceuticals) dictates the complexity of HHP process development.
• Understanding product characteristics is crucial for successful HHP application in food and pharmaceutical industries.
