Flash freezing being used for cryopreservation. Flash freezing is used in the food industry to quickly freeze perishable food items (see frozen food). In this case, food items are subjected to temperatures well below [clarification needed] the freezing point of water. Thus, smaller ice crystals are formed, causing less damage to cell membranes. [4]
From 1929, Clarence Birdseye introduced "flash freezing" to the American public. Birdseye first became interested in food freezing during fur-trapping expeditions to Labrador in 1912 and 1916, where he saw the natives use natural freezing to preserve foods. [5]
By reducing the temperature of cooked food from +70 to +3 °C (158 to 37 °F) or below within 90 minutes, the food is rendered safe for storage and later consumption. This method of preserving food is commonly used in food catering and, recently, in the preparation of "instant" foods, as it ensures the safety and the quality of the food product.
After getting drenched this week, the Northeast will face a rapid drop in temperatures, creating conditions for flash freezing and making Thursday's commute icy and dangerous.
Freezing keeps food safe to eat indefinitely, but these 39 foods significantly decrease in quality if they reach subzero temperatures.

The anti-griddle maintains a constant temperature of -30°F (c. -34.4°C) by pumping a refrigerant through a compressor to remove heat from its steel surface. [6] Liquids, oil, and gels generally freeze in 30 to 90 seconds. The finished product has a crunchy outer texture while the inside remains soft or creamy.
