The rate at which heat is removed from a food during freezing depends on how fast heat can travel within the food and how efficiently it can be liberated from the surface of the food into the surrounding atmosphere. There are various methods of commercial freezing and various kinds of refrigerants used by.
In general, the term freezing refers to the process in which the temperature of the food is reduced to a temperature below its freezing point, while the term frozen is used to describe the subsequent state the food is kept in, i.
Jan 20, 2022 · Replacing milk fractions with whey provides interesting physicochemical changes, cheaper production, and an alternative to whey's disposal, considering it is one of the main polluting residues in the dairy industry.

However, freezing is not suitable for all foods and freezing does cause physical and chemical changes in many foods that are perceived as reducing the quality of the thawed material.
Advances in food freezing/thawing/freeze concentration modelling and techniques. .
Sep 6, 2012 · Freezing is a well-established food preservation process that produces high quality nutritious foods that offer the advantage of a long storage life. In order to increase cooling and freezing efficiencies and ensure better food quality, many efforts have been performed.
The BFC, as well as all the freeze concentration techniques, is a promising technology to be applied in dairy processes and new. Examples of unit operations common to many food products include cleaning, coating, concentrating, controlling, disintegrating, drying, evaporating, fermentation, forming, heating/cooling (heat exchange), materials handling, mixing, packaging, pumping, separating, and others. Freezing is a well-established preservation method used to maintain the freshness of perishable food products during storage, transportation and retail distribution; however, food freezing is a complex process involving simultaneous heat and mass transfer and a progression of physical and chemical changes.
