Bailu, the fifteenth of the twenty-four solar terms, represents the end of the Mengqiu season and the beginning of the mid-autumn season, and is an important seasonal that reflects the temperature changes in nature. Before and after the white dew, the residual summer heat of the summer gradually disappears, the yin qi of heaven and earth rises and spreads, the weather gradually becomes cooler, and the dew in the morning becomes thicker and thicker, condensing into a layer of white water droplets on the grass leaf surface, so it is called "white dew".
In the area of Fuzhou, Fujian Province, there is a custom of eating longan with white dew. So let's take a look at today's protagonist, Longan.
Longan is also known as Guiyuan, puzzle. The local people of Putian are called three-foot agricultural flavor; evergreen trees, usually more than 10 meters high. The fruit is nearly spherical, usually yellowish brown or sometimes grayish yellow, with a slightly rough outer or slightly convex small tumor; the seeds are brown, shiny, and all wrapped in a fleshy pseudoseed.
The fresh longan flesh is crisp and sweet, and is known as the "god of fruit". It is rich in protein, glucose, crude fiber, sucrose, vitamins, amino acids, choline, fat and trace elements calcium, iron, phosphorus and other nutrients. Among them, the sugar and iron content in the eyes of the dragon are very high, and it also contains niacin and vitamin K, which are rare in other fruits.
According to the measurement, every 100 grams of longan pulp contains 12%-23% of whole sugars, 26.91% of glucose, long-term sick, frail people often eat longan can improve heat energy, supplement nutrition.
