Theoretical strain ranges in raw meat

Area of Science:

• Food Science
• Biophysics
• Materials Science

Background:

• Understanding meat rheology is crucial for processing and quality assessment.
• Meat's mechanical properties change significantly during rigor mortis.
• Collagenous fibers play a key role in meat texture and deformation.

Purpose of the Study:

• To analyze rheological data from raw meat compression tests.
• To establish a method for evaluating structural components based on deformation.
• To define strain ranges for analyzing specific meat tissue structures.

Main Methods:

• Compression testing of raw meat samples.
• Expressing rheological data based on actual meat length ratio, accounting for pre- and post-rigor strains.
• Analyzing the relationship between collagenous fiber deformation and overall meat sample deformation.

Main Results:

• A critical compression ratio was identified at which collagenous fibers become tense.
• A theoretical curve was developed to predict critical compression ratio variations based on initial sample state.
• Theoretical strain ranges were defined for analyzing muscle fibers, elastin fibers, or collagenous fibers.

Conclusions:

• The developed method allows for the analysis of specific structural components within meat based on rheological behavior.
• This approach provides a framework for understanding how different tissue structures contribute to meat's mechanical properties.
• The findings can inform meat processing techniques and quality control measures.
