Frozen food is defined as food that has been frozen and kept at a low temperature for a long time. Frozen foods maintain their minerals and vitamins, and their protein, carbohydrate, and fat composition remain unchanged. Frozen foods have more minerals and vitamins than fresh meals in some circumstances, as fresh foods lose minerals and vitamins with time, whereas freezing maintains the nutrients. Thermal conductivity, specific heat, enthalpy, density, and latent heat are all important factors to consider while freezing food.
Frozen food is food that has been processed and stored without cooking. While there are many great benefits to eating frozen food, it does come with some risks and disadvantages as well. Before buying this type of food, it is important to know what the benefits and drawbacks are. Some frozen foods contain large amounts of trans fats, which can not only clog the arteries but also make the user prone to heart diseases. Frozen food may also increases the cholesterol level of the body, which in turn leads to many heart related problems.
Soup, prepackaged meals, beef and poultry, vegetables and fruits, and fish are all available frozen. The main users of frozen food are hotels, restaurants, caterers, and fast-food franchises. Fresh food, which comes in trays and must be heated before serving, is a quick, convenient, economical, and healthful alternative to frozen ready meals. Frozen ready meals can be kept frozen for several months without losing their quality. As a result, ready meals are in high demand, as freezing prevents microbial and fungal contamination.
In the Asia Pacific (APAC), demand for frozen food has increased due to shifting consumers’ food preferences towards ready-to-eat food products. For example, in March 2021, ADF Foods commenced commercial production of frozen breads, snacks, and ready to eat products at its manufacturing facility in Gujarat, India to fulfil increased demand of these products.
