Area of Science:

  • Animal Science
  • Food Science
  • Agricultural Technology

Background:

  • Increasing demand for high-quality Hanwoo beef in Korea.
  • Marbling score is a key factor in meat palatability, but fleck distribution also impacts quality.
  • Customer satisfaction depends on both marbling degree and fineness.

Purpose of the Study:

  • To develop a novel index for quantifying marbling fineness in Hanwoo beef.
  • To assess the effectiveness of the F7 index in differentiating marbling textures.
  • To explore the potential of the F7 index in improving Hanwoo beef quality grading.

Main Methods:

  • Utilized computer marbling analysis technique on 256 Hanwoo sirloin cuts.
  • Developed the F7 index, defined as the standard deviation of marbling particle area ratios.
  • Determined optimal step size (70 tiles per axis) for the F7 index calculation.

Main Results:

  • The F7 index significantly discriminated between finely and coarsely marbled sirloin (Beef Marbling Score 6-9).
  • Achieved high statistical significance (P value = 1.340 × 10-27) in differentiating marbling fineness.
  • Demonstrated the F7 index's ability to quantify marbling fleck distribution.

Conclusions:

  • The F7 index shows great potential to enhance the accuracy of Hanwoo beef quality grading.
  • This index can supplement the traditional marbling score for more precise quality assessment.
  • The F7 index may support the development of improved breeding strategies for Hanwoo cattle.
