Invented by the Song Dynasty, it evolved from the invention of frying corn kernels in oil pan.

Popcorn was invented in the Song Dynasty. Fan Chengda recorded in "Wujun Chronicle·Customs": "In the Shangyuan Dynasty, the glutinous rice was popped in the cauldron. It was named Bolou, also called rice popcorn. Each person blew himself up to predict one year's good fortune."

.

When the New Year comes, people in the Song Dynasty use popcorn to predict the good and bad luck of the year, and girls use it to predict their own life events.

The people of the Song Dynasty added food to culture to give it a richer connotation. Therefore, the popcorn machine was invented by the people of the Song Dynasty and has been continuously improved since then, such as adding pressure indicators.

In January 2013, the popcorn machine, which is common in China, aroused the curiosity of Americans and was featured on the famous show "MythBusters" on the Discovery Channel in the United States. It later developed into today's popcorn.

Extended information: 1. Historical source: Popcorn originated in the Song Dynasty of China. Fan Chengda, a poet at that time, mentioned the custom of popcorn in Wuzhong during the Lantern Festival in his "Shihu Collection" and explained: "

Fried glutinous rice is used for divination, and the name of the valley is Bolou, and the people in the north call it glutinous rice popcorn. "Why do people call popcorn "Bo Lou"?

The popcorn is thought to imitate the sound of popping corn, because the local dialect calls the sound of thunder "poulong".

The invention of popcorn further reflects the richness and variety of Chinese food. It has a deeper meaning, which is the creation of a food processing method called puffed food.

It shows that food processing in ancient China is not just about simply heating and cooking food, but also changing the state and taste of food through the physical principle of high temperature and high pressure. This processing method is the emerging modern puffed food.

This processing method turns ordinary unpalatable food into delicious and distinctive food snacks. It can be said that popcorn thousands of years ago is the ancestor of all kinds of puffed food snacks in modern times.

2. Preservation method Since popcorn is easily affected by moisture, it will lose its crispy and delicious taste after being affected by moisture. Therefore, popcorn is not easy to store for a long time and should be eaten while it is fresh.

If stored, it must be placed in a ventilated and dry place to prevent moisture.
