It is also the king of fruit for 10 years, and it has to be soaked in water before it can be picked. Few people have eaten it.

With the development of the global economy, we often see a lot of imported food in people's daily life. There are some fruits and snacks that have never been eaten before, such as durian and mango from Thailand, dragon fruit with hearts from Vietnam, blueberries from Chile and other fruits. There is also a kind of "ruby" fruit from North America and Chile, which is not grown in China, but mainly depends on imports, and has become a very popular object in recent years. This kind of fruit has high health value and good taste. Although the price is not cheap, it is still very popular with young people. However, because of its special picking method, few fresh fruits are sold, and most of them are dried fruits, so few people have eaten fresh ones.

This kind of fruit is small in shape and looks like red beans when it is ripe. It is a kind of berry called cranberry. It is a very interesting fruit, first of all, it likes to grow in cold wetlands, and then it blossoms in autumn and bears fruit in winter and spring, which can be said to be very different. Because the growing place is cold, its growth rate is very slow, and some branches will not bear fruit until they go through a 10-year growth cycle. However, once the result, its yield is still very objective, the high yield period is at least more than 10 years. Secondly, cranberries like high-acid sandy soil, which most fruits can't stand, but can produce excellent quality cranberries.

Then the picking method of cranberries is also excellent, that is, the way of "water harvest" is adopted. As the cranberries are low shrubs, before harvesting, fill the field where the cranberries are located with water, soak them overnight, and the next day use a special "water wheel" to draw water back and forth in the fields, and the cranberries will fall off. There is air in the fruit cavity of cranberries, which will all float on the water. Then farmers only need to surround the farmland to catch all the cranberries in one net. This peculiar method of harvesting takes place every year in North America, where it is produced, and the water is covered with red cranberries.

Because cranberries are harvested after soaking in water, most of them are sent directly to the processing plant after harvest, where they are sterilized, dried with hot air and dried. Others are made into fruit jams, fruit juices, fruit vinegar, and health products. Because of the high nutritional value of cranberries, the contents of vitamin C and flavonoids are among the best in fruits, which can not only beauty and beauty, but also prevent female urinary tract infection and cystitis, as well as stomach ulcers, hypertension and other diseases. Because it contains a special substance-concentrated tannic acid, which can inhibit the reproduction of pathogenic bacteria in the body.

It is precisely because of its high nutritional value and health care that cranberry is known as the "king of fruit" in North America. Some people who like to eat imported food may have eaten dried cranberries, but for most people, it is still very far away and few people have ever eaten it.
