Frozen foods refer to food products that are preserved through freezing, typically at very low temperatures. This process halts bacterial growth and enzymatic reactions, allowing for extended shelf life without refrigeration. Frozen foods can be prepared meals or individual ingredients such as fruits, vegetables, meat, poultry, seafood, and even ready-to-eat breakfast cereals. They are convenient to store and use since they do not require constant refrigeration, making them a popular choice for busy households and individuals who want healthy meal options without the hassle of cooking from scratch every day.
