Individual quick freezing, usually abbreviated IQF, is a descriptive term for freezing methods used in the food processing industry. The food is in individual pieces, and is frozen quickly. Products commonly frozen with IQF technologies are typically smaller pieces of food, and can include berries, fruits and vegetables both diced or sliced ...
The product may be in direct contact with the liquid, or be separated by a membrane. It can be used for freezing the outer shell of large particles to reduce water loss. Individual Quick Freezing is a descriptive term that includes all forms of freezing that is "individual" (not in a whole block) and "quick" (taking a maximum of several minutes ...
Flash freezing. In physics and chemistry, flash freezing is the process whereby objects are rapidly frozen. [1] This is done by subjecting them to cryogenic temperatures, or it can be done through direct contact with liquid nitrogen at −196 °C (−320.8 °F). It is commonly used in the food industry.

He compares quick-freeze deep-etch electron microscopy to using a stroboscopic flash to freeze the action in a photograph. To make it possible to image the frozen sample with an electron microscope, Heuser adds an ultra-thin film of metallic platinum that molds snugly against the sample's frozen surface contours. He and others in his lab have ...
To pack pears in syrup, first prepare a syrup of sugar and water in a saucepan and heat until the sugar dissolves (use two to four cups sugar for every four cups water). Bring the syrup to a ...
