Jiangnan’s Spring Limited Food “Qingtuan”: The Little Secret Behind the Delicious Taste
As someone who grew up in the Jiangnan region, the food I looked forward to most every year during the Qingming period was qingtuan. This traditional snack, which encapsulates the taste of spring, is a shared taste memory of people in Jiangsu, Zhejiang and Shanghai. But what you may not know is that these small, fresh-looking green balls actually hide a lot of health secrets.
1. What is Qing Tuan?
Qing Tuan is a traditional springtime snack from the Jiangnan region. The skin is dyed a greenish-blue color with fresh mugwort juice, and it contains either sweet or savory fillings. Common flavors include:
- Sweet fillings: red bean paste, black sesame, date paste
- Savory fillings: fresh meat and bamboo shoots, salted egg yolk and pork floss
In recent years, innovative flavors such as crayfish and taro paste with cheese have also become popular. Essentially, qingtuan is a glutinous rice product made with glutinous rice flour, which is used to wrap various fillings. Freshly steamed qingtuan has a light fragrance of mugwort and is soft and chewy, making it irresistible.
2. Digestion Challenge: A Common Issue for Glutinous Rice Products
2.1 Properties of Amylopectin
The main ingredient in the skin of qingtuan is glutinous rice flour, which contains abundant amylopectin. This starch forms a very viscous structure when heated:
- Easily digestible when hot
- Becomes stickier and harder to break down when cooled
2.2 Modern Eating Habits Exacerbate Digestion Issues
Many qingtuan products are designed for cold consumption:
- Cold qingtuan is 30% stickier than hot ones
- Harder for stomach to break down into small particles
- Digestive juices have difficulty penetrating the food matrix
2.3 Combined Effect of Fillings
Modern fillings often contain:
- High-fat ingredients: salted egg yolk, fatty meat, cheese
- High-sugar options: taro paste, custard
The combination creates a “complex food” requiring extended processing time by intestines.
