Liquid nitrogen is a type of refrigerant that is extremely cold, with a temperature of around -196°C. It has been used in the food and beverage industry to create a range of dishes and drinks, including cocktails, ice cream, and other frozen treats.
It is generally safe to consume foods and drinks that have been made with liquid nitrogen, as long as they are prepared properly. However, there are some risks to consider. When liquid nitrogen is added to a drink or food, it can cause the temperature to drop rapidly, which can lead to frostbite if it comes into contact with skin. Additionally, if the liquid nitrogen is not fully evaporated before the drink or food is consumed, it can cause extreme cold burns to the mouth and throat.
To make a drink with liquid nitrogen, the liquid nitrogen is typically added to the drink just before serving. The liquid nitrogen will quickly evaporate, leaving behind a cold, misty effect. The drink should be stirred well to ensure that the liquid nitrogen has fully evaporated before it is consumed. It is important to use caution when handling liquid nitrogen, as it can cause serious injury if it comes into contact with skin or is ingested.
