The term indicates that the ribs were subjected to freezing temperatures at some point before being offered for sale. This means the product was frozen, stored, and then thawed, either by the retailer or potentially earlier in the supply chain, prior to reaching the consumer. The ribs might be sold fresh after thawing, without the explicit labeling of “previously frozen,” or the label might be present to inform the customer.
Understanding that ribs were once frozen allows consumers to make informed purchasing decisions. Freezing is a common preservation method that can extend the shelf life of meat products, mitigating spoilage and waste. However, the process of freezing and thawing can impact the texture and, to a lesser extent, the flavor profile of the ribs. The structural integrity of the muscle fibers may be slightly compromised, potentially leading to a less firm or juicy end product after cooking.
