[Effect of enzymatic meat tenderizers]

Area of Science:

• Meat science
• Food technology
• Biochemistry

Context:

• Meat toughness is a significant challenge in the food industry, impacting consumer satisfaction and processing efficiency.
• Existing meat tenderization methods often lack specificity or negatively affect meat quality.
• Understanding the biochemical basis of meat texture is crucial for developing effective tenderization strategies.

Purpose:

• To investigate the efficacy of novel intramuscular tenderizing preparations on meat texture.
• To elucidate the specific mechanisms by which these preparations affect muscle proteins and connective tissue during cooking.
• To differentiate the effects of these preparations from natural meat aging processes.

Summary:

• Tenderizing preparations are administered intramuscularly or intravenously, distributing within the endomysium and perimysium.
• These agents effectively target the collagenous portion of connective tissue during specific cooking temperature ranges.
• While sarcoplasmic proteins are affected, myofibrillary proteins remain largely intact, leading to reduced collagen-induced toughness and general structural loosening.

Impact:

• This research offers a novel approach to meat tenderization, focusing on collagen degradation.
• The findings provide insights into controlling meat texture by selectively targeting connective tissue.
• The developed preparations offer a potential alternative to natural aging, improving meat tenderness efficiently.
