Tangyuan, also known as Yuanxiao, Tangtuan and Floating Yuanzi, is one of the representatives of traditional snacks in China, and it is a spherical food made of glutinous rice flour. There are usually fillings, cooked and eaten with soup. At the same time, it is also the most distinctive food of the Lantern Festival with a long history.

Tangyuan originated in the Song Dynasty. At that time, Mingzhou (now Ningbo City, Zhejiang Province) began to eat a novel food, that is, black sesame seeds and lard were used as stuffing, a little white sugar was added, and glutinous rice flour was rubbed into a circle outside. After cooking, it tasted sweet and delicious, and it was very interesting. Because this glutinous rice dumpling is floating and heavy when cooked in a pot, it was originally called "Floating Yuanzi", and later it was renamed as glutinous rice dumpling in some areas.

Extended data

When buying Yuanxiao, you must see the package, manufacturer, date and logo clearly. See if the packaging is damaged or leaked, and whether there is a problem of counterfeiting well-known brands; See if the name, address, postcode and telephone number of the manufacturer on the food packaging and label are complete and detailed.

See if the food is marked with production date and shelf life; Whether there is a health approval number, production approval number, food label approval number and other qualification approval numbers; Whether there are product implementation standards and "QS" signs, etc. In addition, there should be trays in the packaging bags of good quality Yuanxiao, so as to prevent the Yuanxiao from being squeezed and deformed during transportation.

Then look at the appearance of Yuanxiao. Look at the color and shape first. Good Lantern Festival is white in color, without miscellaneous points and round in shape. The inferior Yuanxiao is dim and uneven in color and irregular in shape. Let's see if there are cracks in the Lantern Festival. If the freezing technology doesn't pass, Yuanxiao will crack easily, so the water and nutrients of Yuanxiao will be lost greatly and the taste will be rough.
