Frozen food refers to any type of food that has been preserved by freezing it at a very low temperature, typically below 0 degrees Celsius. This process helps to extend the shelf life of the food and maintain its nutritional value, flavor, and texture. Frozen food can include a wide range of products, such as fruits, vegetables, meats, seafood, prepared meals, and desserts. It is a convenient and cost-effective option for consumers who want to save time and reduce food waste, as it can be stored for long periods of time and easily prepared when needed.
