Yes, coating meat in spices before cold storage can help inhibit bacterial growth and enhance flavor, but it's crucial to use the right spices and ensure the meat is properly stored.
Applying a dry rub of spices to meat before refrigeration or freezing can offer several benefits. Many spices, such as garlic powder, onion powder, paprika, and chili powder, possess antimicrobial properties that can help slow down the growth of bacteria and mold, thus extending the meat's shelf life. Furthermore, the spices will begin to penetrate the meat during storage, resulting in a more flavorful product when it's cooked. However, it's important to use fresh, high-quality spices and to ensure the meat is properly wrapped or sealed to prevent freezer burn or contamination. The spices should be rubbed evenly over the entire surface of the meat. For best results, consider using a combination of spices that complement the type of meat you're storing. For example, a blend of rosemary, thyme, and garlic is excellent for lamb, while paprika, cumin, and chili powder work well with beef.
Avoid using salt in your spice rub if you plan to store the meat for an extended period in the freezer. Salt can draw moisture out of the meat, leading to a tougher texture after thawing. Add salt just before cooking instead.
