BACKGROUND
Beef color is a critical factor influencing consumer purchasing decisions, particularly in the retail market, where consumers prefer a bright cherry red color. Dark-cutting beef, which results from pre-slaughter stress leading to a higher postmortem pH, deviates from this ideal color, presenting a significant challenge for the beef industry. This condition not only affects the visual appeal of raw beef but also causes a persistent undercooked appearance in cooked meat, reducing its overall acceptability. Addressing these color challenges is essential for improving the marketability of dark-cutting beef and ensuring consumer satisfaction.
To tackle this issue, research has explored various post-harvest techniques, including antioxidant enhancement and modified atmosphere packaging. Recently, the development of biodegradable poly- (lactic acid) (PLA) films containing sodium nitrite and α-tocopherol has shown promise in improving the surface color of dark-cutting beef. These films enhance redness while minimizing undesirable cooked color changes, offering a potential solution that aligns with global efforts to reduce single-use plastics. This innovative approach not only improves the color stability of dark-cutting beef but also contributes to sustainability in the meat industry.
SUMMARY OF TECHNOLOGY
OSU researchers have developed a biodegradable nitrate transfer film for meat packaging addressing a critical need in the food industry by improving the visual appeal and extending the shelf life of meat products, particularly dark-cutting beef, which often struggles with color retention. By integrating active ingredients such as sodium nitrite and α-tocopherol into PLA films, the innovation not only enhances the meat's redness during retail display but also maintains color stability throughout the product's lifespan without compromising food safety. This approach, which aligns with sustainable packaging practices, holds significant potential for improving meat marketability while adhering to environmentally friendly standards.
