What is the heat of the old hand-cranked popcorn?

The heat of old hand-cranked popcorn is about 360 kcal/100g.

Popcorn is processed from corn, rich in fiber, low in calories and almost free of sugar, salt and fat. However, in order to improve the taste of microwave popcorn, many additional ingredients are added, so it is no longer a healthy nutritious food. It is a good choice to choose cheap bulk products when buying popcorn, and control the amount of salt and butter by yourself.

Popcorn is not necessary, and ordinary popcorn is unhealthy, so it is not recommended in principle. In addition, diacetyl, a component in popcorn, is safe for normal use, but lung injury does exist in the case of long-term inhalation (such as popcorn factory workers or popcorn addicts).

Extended data:

Difference of nutritional value between traditional popcorn machine and modern microwave oven in China;

The processing method of microwave oven is more convenient and sanitary. In the past, the sealing layer of popcorn machine was mostly cast iron with lead. Because the melting point of lead is only over 300 degrees Celsius, the instantaneous temperature can reach 400 degrees Celsius in the process of making popcorn, so lead vapor will pollute popcorn and lead will exceed the standard. Microwave ovens make polar molecules in food rotate through electromagnetic fields, and generate heat through friction. The overall nutritional loss is less than other common processing methods.
