In the modern food-processing world, refrigeration technologies are essential to prolonging food storage and maintaining quality. The IQF, Individual Quick Frozen, is a revolutionary refrigeration technology that can freeze fast food for a very short period of time and effectively maintain its quality, nutritional value and taste. This technology is widely used in the processing of foods such as fruit, vegetables, meat and seafood. This paper will explore in depth how IQF technology works, its main strengths and its applications in the food processing industry, and will analyse future trends and challenges to help readers understand how this key refrigeration technology can improve food quality and efficiency.
(IQF)Technical overview
(IQF)Technical definition
IQF is an advance technology for frozen foods, the main purpose of which is to freeze rapidly every food unit at extremely low temperatures to protect the quality and sustenance of foods. Unlike traditional refrigeration methods, IQF techniques can prevent food from forming large crystals during the freeze process, which helps to maintain the original structure and quality of food. IQF technology is usually used in a variety of food types such as frozen fruit, vegetables, meat and seafood.
(IQF)Different from traditional refrigeration techniques.
Traditional refrigeration techniques typically employ a gradual cooling method, which makes it easier for foods to form larger crystals. These big crystals can destroy the cell structure of the food, leading to a deterioration in the quality of the food once it is unfrozen. By contrast, the IQF technology enables foods to reach low temperatures quickly by freezing at extreme speeds, creating tiny crystals of ice that can better maintain the quality and taste of food.
(IQF)History and background of technology development
IQF technology originated in the 1950s and was first developed to improve the quality of frozen food. IQF technology is becoming a standard technology for the global food-processing industry as technology progresses and equipment upgrades. The development of this technology has not only boosted the freezing effect of food, but has also contributed to the expansion of the frozen food market.
(IQF)Technical principles.
The main steps in the freeze process.
- Food pre-processing
Food products require pre-treatment before they are frozen, including cleaning, cutting, decorating and grading. These steps help to remove unnecessary parts and to ensure that food is equal and good in the freeze process. - Temperature
Refrigeration is the process of cooling foods before freezing to near freezing points. This process will help to reduce the heat load of food entering the freezer segment and to increase the efficiency of the freeze. - Quick freeze.
When the food is pre-cooled, it is sent to an IQF freezer. In chillers, food is rapidly frozen by high-speed air currents or other cooling methods. In this journey, food surfaces quickly reach cold temperatures, from which they form tiny crystals of ice. - Frozen completion and packaging
Once the food reaches its prescribed cold temperature, they are moved to the package area. At this point, food is rapidly packaged to prevent humid or oxidizing during storage and transport to ensure quality. - Storage and distribution
When the package is complete, the food will be stored in a low-temperature environment to maintain its cold state. The food is delivered to markets or consumers via the cold chain distribution system, ensuring that high quality is maintained throughout the transport process.
Key factors in the heat exchange and freezing process
Thermal exchange is the key factor in the IQF freeze process. Through efficient cooling facilities, the surface of the food is rapidly dissipated, making the water in the food rapidly frozen. Rapid cooling can effectively control the size of the crystal from which to protect the quality and nutrients of the food. The air flow speed, cooling temperature and design of the equipment are important factors affecting the freezing effect.
How to get the best of the food.
IQF techniques require precision control of the parameters of the freezing environment in order to achieve the optimal freezing effect. The current speed, temperature gradient and cooling methods in the chiller are carefully designed. In addition, pre-treatment of foods, such as cleaning and cutting, can help to optimize foods during the freeze process.
(IQF)The main edge of technology.
Protection of food quality and taste
IQF technology can be effective in preventing foods from forming large crystals during the freeze process, which do not damage the cell structure of foods. Thus, unfrozen foods can retain their original quality and taste. For example, IQF frozen fruits can still keep their fresh taste and sweetness after they are unfrozen, while traditional methods of freezing may lead to softening of fruit.
Maintenance of nutrients
IQF technology allows maximum conservation of nutrients in food. Because of the rapid cooling of food during the freeze process, nutrients such as vitamins and minerals are not excessively damaged. As a result, IQF frozen food can maintain a nutritional value close to that of fresh food and help maintain consumer health.
Save life extension
IQF technology can increase the life expectancy of food. As food does not form large crystals during the cold-freezing process, the quality and nutrients of food are maintained, reducing food variability and waste. This feature allows IQF to maintain high quality during long storage and transport.
Decrease in volume and weight
IQF technology can also reduce the volume and weight of food, which is important for logistics and storage. Since IQF frozen foods are not bound together, this makes them easier to package and transport, making logistics more efficient and reducing running costs.
Reducing food waste and improving operating efficiency
As IQF technologies protect the quality of food, they reduce the quality and waste of the food, and thus increase the efficiency of the operation. For food-processing companies, not only can they reduce losses, but they can also increase market competition for their products.

This is important for the production of fruit juice, ice cream and ready-to-eat vegetables. IQF technology allows these products to be stored and easily distributed over time while maintaining high quality.
Application in meat and seafood.
IQF technology also plays an important role in meat and seafood processing. For meat, IQF technology can be effective in maintaining the softness of the meat and preventing the loss of moisture; for seafood, IQF technology can protect the taste and nutrients of seafood. IQF frozen meat and seafood were widely recognized on the global market.
Applications in processed foods
IQF technology is also used in the production of various processed foods such as frozen fast foods and ready-to-eat foods. By freezing IQF, these processed foods can be preserved for long periods of time while preserving their original taste and sense of quality. This is important for fast-distribution markets.
