Discuss the modern processing technologies to improve quality of meat and meat products.
Modern technologies aim to enhance the safety, quality, and sensory attributes of meat products while reducing chemical preservatives.
High-Pressure Processing (HPP): Non-thermal treatment where packaged meat is subjected to very high hydrostatic pressure. HPP inactivates pathogens and spoilage microorganisms without affecting flavor, texture, or nutrition, extending shelf life and improving tenderness.
Pulsed Electric Fields (PEF): Short, high-voltage pulses create pores in cell membranes, enhancing mass transfer for marination and inactivating microorganisms. Used for tenderization and as a pre-treatment in processing.
Novel Packaging Technologies:
- Active Packaging releases or absorbs substances (e.g., antimicrobials, oxygen scavengers) to extend shelf life.
- Intelligent Packaging monitors product condition with freshness or time-temperature indicators.
- Modified Atmosphere Packaging (MAP) alters gas composition (O₂, CO₂, N₂) to inhibit microbial growth and discoloration.
Ultrasound Technology: Improves tenderness, marination, and emulsification in comminuted products.
These innovations focus on safety, shelf-life extension, texture improvement, and consumer preference for minimally processed, natural meat products.
