Chapter 7 Section 4 Hawthorn, the best fruit with the most calcium

Hawthorn (Crataegus Pinnatifida) is one of the fruit trees native to China.It has been recorded in "Erya" 2000 years ago: "The tree is like a plum, and its seeds are like fingers. The color is red and the fruit is small, edible. This is the hawthorn." Some places of hawthorn are called Hongguo and Shanlihong. Hawthorn is a tree with no spines on the branches and glabrous shoots. The weight of a single fruit is about two to three grams.The most famous variety is the red-fleshed hawthorn in Xinglong, Hebei. The flesh is bright red, round in shape, sweet, sour and waxy.The large golden star fruit produced in Fushan, Shandong Province is large and thick, with a moderately sweet and sour aroma.Liaoning has soft-core hawthorn, and the pulp and core can be eaten together. Others include purple hawthorn, red-mouthed hawthorn, and earthy yellow fruit.From Heilongjiang and Liaoning in northern China to Guangxi and Yunnan in the south, there are many hillsides and valleys below 2000 meters above sea level where hawthorn fruit forests can be seen.The concentrated production areas of hawthorn are the Shandong Peninsula, inside and outside the Great Wall, and low mountainous areas in Liaoning, Shanxi, Hebei, Henan and other provinces.Hawthorn fruit is worth more and more in recent years, because it contains the most calcium in fruits, 85 mg of calcium per 100 grams of fresh fruit, 89 mg of vitamin C, which is 17 times higher than that of apples, and it also contains citric acid, protein and other elements, which can lower blood pressure and cholesterol, aid digestion.It tastes sweet and sour, processed into "hawthorn cake" (golden cake), the color is as sweet as rouge, and the string of "candied haws" is sweet and crisp, which is a food with unique flavor.
