The ice-water interface is commonly encountered in our life, and comes into play in a wide number of natural phenomena. Here, attention will be focused on its effects on protein stability, with specific reference to the case of pharmaceutical proteins. This field represents a fascinating, and not yet fully understood, subject of investigation.
17 The superchilling rate is not the only factor that affects ice crystal size, because growth of ice crystals can occur over the entire storage period. 18 Larger ice crystals can severely damage
Abstract. The demand for cooling, such as that of products, spaces, and processes, has increased with the development of urbanization. Cold storage can shift the valley time of electric power to cold energy. Compared to the fixed cold storage routine, mobile cold storage can eliminate site limitations. Ice slurry, as a new functional fluid, has

(Citation 2002) studied the impact of temperature fluctuations (−30 C to −10 C) over the period of 8 months on Mozzarella cheese used as pizza topping and reported
Cold thermal energy storage provides suitable solutions for electric air conditioning systems to reduce peak electricity use and for solar cooling systems to alleviate energy supply intermittency. Due to the high latent heat (501–507 kJ kg −1), CO 2 hydrates have been widely reported as promising cold storage media that suit a wide range of air
Preservation of meat through freezing entails the use of low temperatures to extend a product''s shelf-life, mainly by reducing the rate of microbial spoilage and deterioration reactions. Characteristics of meat that are important to be preserve include tenderness, water holding capacity, color, and flavor. In general, freezing improves meat
Judging from its common characteristics, its vacuum ice-making system comprises four parts: water supply device, vacuum flashing device, vacuum maintaining device, and ice slurry storage device, which can realize the output of its ice-making working fluid. As shown in Fig. 3a Schematic diagram of four parts of vacuum ice-making system.

This review summarizes the theoretical conditions of making fluid ice from supercooled water, the ice making process, and two system forms of making ice from supercooled water. Theoretical conditions include thermodynamic principles and ice
The increase of heat and mass transfer efficiency in turn promotes ice crystallization, resulting in the improvement of freezing rate [ 85 ]. In recent years, the
A good understanding of the relationship between food microstructure and ice morphology, as well as the ability to effectively measure and control ice crystals, is
The new ice crystals formed at the centre during storage are large, due to a slow superchilling rate. Download : Download full-size image Fig. 7. Intracellular ice crystals at the centres (0.014 m from the surface) of post- and pre-
The small amount of free water (5–30%) which converted to ice will be used as an internal cold reservoir so there is no need for external ice around the product during distribution or storage. Superchilling significantly extends the potential number of environments in which high-quality food can be provided at reasonable costs (Wang,
Most of the studies related to the measurement of the recrystallization rate (Hagiwara et al., 2006) by determining the ice crystals size distribution and ice crystals mean size deals with microscopy and image analysis (Donhowe et al., 1991, Sutton et al., 1994, Donhowe and Hartel, 1996a, Donhowe and Hartel, 1996b, Regand and Goff, 2003,
The morphology of ice crystals plays an important role in the sensorial properties of foods that are consumed in the frozen state. For example, the texture of ice
However, ice crystals formed during freezing may result in the breakage of cell structure, leading to quality deterioration. In order to better understand the
For more than 12 h storage time, the ice slurry could not flow in the tube. The adhesion between ice particles seemed to cause a blockage in the tube. On the other hand, for turbulent flow, the

As innovative techniques, magnetic field technology can be used in freezing and thawing processes that are intended to enhance the quality of frozen foods. An induced magnetic field can improve flavor, texture, appearance, and freshness retention during freezing and thawing. The magnetic susceptibility of a material.
Thermal energy storage is used to assist in the effective utilization of thermal energy in industrial applications [1,2,3,4]. Ice slurry as anenergy storage medium is a very interesting solution thanks to the high energy storage density and fast cooling capacity [ 5, 6, 7 ].
Freeze food quickly and at as low a temperature as possible. Zero degrees F or lower is recommended. If you are freezing a large quantity of food at one time, set the freezer temperature 10 degrees lower than normal until the food is frozen. To avoid fluctuating temperatures do not open the freezer more than necessary.
There are few reasons why your food loses moisture and gets coated with a layer of ice. Before that, let''s us look at what the types of ice crystals and what they mean. Small ice crystals found on your meat indicates a loss of moisture in your food. Large ice crystals on the other hand mean that your meat has been thawing and freezing back
Precise control over crystallization in foods is essential for extended quality preservation of the food products. The main components that form crystalline phases in foods are water (ice), sugars, sugar alcohols, lipids, salts and starches. Other components that may crystallize include organic acids (citric acid), proteins and emulsifiers.
