In everyone's daily life, fresh fruit is a common ingredient, and it is also a key source of nutritional elements for everyone. It is often heard that people argue about which fruits have high vitamin C content and which fruits have the first vitamin C content, but few people care about which fresh fruits have high calcium content. This kind of fresh fruit is called "the first one with calcium content" in its planting area, and its calcium content is far higher than other fresh fruits. Deeply loved by local people, this fresh fruit has a distinctive appearance design, which is a bit like a big peanut. It is memorable at a 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 about 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 vacation and travel, and they can see the sour corn sold in the fresh fruit shop. The huge "peanut kernel" attracted people's attention. Of course, the pulp of tamarind is completely different from peanut kernel. 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, which you can bite 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 sugar, vitamins, calcium, iron, magnesium and other nutrients, and 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 kind of fresh fruit, Suanzao has less meat and low edible rate, which is not up to standard. In order to make better and flexible use of this nutrient-rich fresh fruit resource, in its planting area, everyone produces and processes it into garlic and pepper cake, garlic and pepper dried fruit, crystal jelly, apple sauce and other leisure drinks, which are also warmly welcomed by customers. After being processed according to the sour angle, 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 croissants 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 indeed 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.

However, if it is sour, it will be called sour corn and can be eaten immediately. However, because it tastes too sour, few people eat it immediately. Sour corn has a fresh fruit flavor that other condiments do not have, and can be used to make water-based condiments. 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 decreasing, and most of 6 yuan's money 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 it is a tree over ten years old, its branches are full of fruits in the fruiting period, which looks very gratifying. Moreover, the tree has a large trunk and a beautiful tree shape, which is suitable for planting as an ornamental tree.
