In everyone's daily life, fresh fruit is a common ingredient and a key source of nutritional elements for everyone. It is often heard that people argue about which fruit has high vitamin C content and which fruit has the first vitamin C content, but few people care about which fresh fruit has high calcium content. This kind of fresh fruit is called "the first in calcium content" in its planting area, and its calcium content is far higher than other fresh fruits. It is deeply loved by local people, and the design of this fresh fruit is very distinctive, a bit like a big peanut, which is memorable at first glance. This kind of fresh fruit is tamarind, also called tamarind locally. It is an unpopular fresh fruit, which is not common in the market at present, so many people don't know it. Mainly distributed in Yunnan, Guangxi and Hainan provinces with long-term warm climate, especially in valleys and coastal counties.

Many people go to Yunnan Province for holiday travel, and they can see sour horns sold in fresh fruit shops. The big "peanut kernel" attracted people's attention. Of course, the pulp of tamarind and peanut kernel are completely different. After peeling off its shell, the pulp inside is very similar to dried longan meat. There is a thin layer on the flat peach core, and you can hold that layer with your teeth when eating. Now the sour corn planted by improved grafting method has a little sweetness, which is also called sweet and sour corn or sweet corn. That doesn't sound so sour. Sour corn is rich in nutrients such as sugar, vitamins, calcium, iron, magnesium, etc. It is also a healthy fruit described in Compendium of Materia Medica. It has the effects of invigorating stomach, promoting digestion and relieving summer heat, and is of great value in taking and using.

However, as a fresh fruit, Suanzao has less pulp and low edible rate, which is not up to standard. In order to make better use of this nutrient-rich fresh fruit resource flexibly, in its planting area, it is produced and processed into leisure drinks such as sour horn cake, sour horn dried fruit, crystal jelly, applesauce, etc., which are also warmly welcomed by customers. After processing according to the sour horn, not only the nutrients are preserved, but also. I firmly believe that many friends who travel to Yunnan have eaten or bought some special foods such as sour horn cakes and dried fruits. In fact, there are many ways to eat sour horns. In Yunnan province, where people like to eat spicy food, people will continue to add it to various dishes, but it is really a fresh fruit and a local specialty of Yunnan province. It is called Suanjiao, belonging to Leguminosae, which is divided into two categories, one is sweet and the other is sweet.

But if it is sour, it is called sour corn and can be eaten immediately. But because the taste is too sour, few people eat it right away. Sour corn has a fresh fruit flavor that other condiments do not have, and can be used as a soaking seasoning. It can also be added to fish, chicken breast and other ingredients to improve the taste of dishes. In the past, the total planting area of sour corn was not large, but after the development trend, the total planting area of sour corn increased greatly. The price is gradually falling, and most of the 6 yuan can buy a catty of fruit. The improved Ziziphus jujuba trees can blossom and bear fruit within four years. The initial output is not high, and the output will be higher and higher in the next two years. If the tree is more than ten years old, it looks very gratifying when the branches are full of fruits at the fruiting stage. Moreover, Acacia angustifolia has a large trunk and beautiful tree shape, which is suitable for planting as an ornamental tree.
