Structural phase transition-aligned preheating reprograms lipid-derived flavor formation in cooked meat: A case of...

Area of Science:

• Food Science
• Meat Science
• Analytical Chemistry

Background:

• Lipid-derived flavors are crucial for meat palatability.
• Reheating often diminishes these characteristic flavors in pre-prepared meats.
• Understanding flavor generation mechanisms is key to improving meat products.

Purpose of the Study:

• To investigate how structural phase transition (SPT)-aligned preheating affects lipid-derived volatile compounds in cooked meat.
• To elucidate the mechanistic pathway of flavor enhancement through SPT-aligned preheating.
• To provide a scientific basis for optimizing thermal processing of meat.

Main Methods:

• Volatilomic analysis of cooked Tan lamb meat under different SPT-aligned preheating conditions.
• Quantitative lipidomics to analyze changes in lipid species.
• Identification and quantification of key volatile compounds.

Main Results:

• SPT-aligned preheating significantly altered the volatile profile of cooked lamb meat.
• SPT1-aligned preheating notably increased the generation of specific aldehydes, ketones, and alcohols (e.g., hexanal, octanal, 1-octen-3-ol).
• This preheating method accelerated phosphatidylcholine hydrolysis, increasing polyunsaturated fatty acids that subsequently oxidized to enhance flavor.

Conclusions:

• SPT1-aligned preheating provides a mechanistic pathway for enhanced lipid-derived volatile compound generation in cooked meat.
• This approach optimizes thermal interventions to improve the flavor of cooked meat products.
• Findings offer a scientific foundation for developing better meat processing techniques.
