Inspection Systems and Mechanical Removal Systems for Bone and Cartilage Particles in Ground Beef Patties

Area of Science:

• Food Science
• Meat Science
• Food Safety

Background:

• Bone and cartilage defects in ground beef are a food safety concern.
• Two inspection systems, one high-defect and one low-defect, were evaluated.
• Defect removal processing systems were compared for efficacy.

Purpose of the Study:

• To evaluate the effectiveness of different inspection systems on ground beef quality.
• To assess the impact of defect removal systems on bone and cartilage levels.
• To determine if processing systems can reduce defects to meet lower inspection standards.

Main Methods:

• Ground beef was processed under high-defect and low-defect inspection systems.
• Three defect removal systems (none, Weiler Bone Collector, Speco Spiral Groove Plate) were applied.
• Sensory analysis (teeth and tongue) of cooked patties detected bone and cartilage defects.

Main Results:

• Higher levels of bone and cartilage defects were found in the high-defect formulation compared to the low-defect formulation.
• Defect removal systems reduced detected defects in the high-defect formulation.
• Neither defect removal system achieved the low defect levels mandated by the lower inspection standard.

Conclusions:

• Sensory evaluation confirmed differences in defect levels between inspection systems.
• While defect removal systems offer some improvement, they do not fully eliminate bone and cartilage defects to meet stringent standards.
• Grinding significantly reduces the size of remaining bone fragments, potentially making them undetectable by sensory methods.
