The aging process of cheese can also impact its shelf life. Some cheeses, like gouda and cheddar, are designed to be aged for several months or even years, during which time they develop their characteristic flavors and textures. These cheeses typically have a longer shelf life due to their lower moisture content and the development of a natural rind that protects them from contamination. On the other hand, young cheeses like mozzarella and feta are more perishable and require refrigeration to prevent spoilage. Understanding the specific characteristics of different types of cheese can help consumers choose the right product for their needs and ensure that it remains safe to consume.
What is the difference between the “sell by” and “use by” dates on sealed cheese?
The “sell by” and “use by” dates on sealed cheese are often confused with each other, but they serve distinct purposes. The “sell by” date indicates the last day that the retailer should sell the cheese to ensure that it remains fresh and of good quality. This date is typically determined by the manufacturer and takes into account the cheese’s production date, storage conditions, and expected shelf life. The “use by” date, on the other hand, is the last day that the consumer should use the cheese to ensure food safety. This date is usually set by the manufacturer or regulatory agencies and is based on the cheese’s potential for spoilage and contamination.
