IQF Vegetables & Fruits

Frozen foods have outstanding quality and nutritive value. Indeed, some frozen vegetables, such as green peas and sweet corn, may be superior in flavour to fresh produce. The high quality of frozen foods is mainly due to the development of a technology known as the individually quick-frozen (IQF) method. IQF is a method that does not allow large ice crystals to form in vegetable cells. Also, since each piece is individually frozen, particles do not cohere, and the final product is not frozen into a solid block. Various freezing techniques are commonly used in the preservation of vegetables. These include blast freezing, plate freezing, belt-tunnel freezing, fluidized-bed freezing, cryogenic freezing, and dehydrofreezing. The choice of method depends on the quality of end product desired, the kind of vegetable to be frozen, capital limitations, and whether or not the products are to be stored as bulk or as individual retail packages.
