What to do if tomatoes are frozen? Can tomatoes prevent cancer?

What should we do if we get frozen when growing tomatoes? Let me tell you about it:

The first one:

The history of tomato cultivation Tomatoes are native to Peru, Ecuador and Bolivia in South America. In the 16th century, tomatoes were introduced to Europe from Mexico. They were first grown as garden ornamental fruits in Italy, Spain, Britain, France and Central Europe. The fruits are small and brightly colored. It was not until the 17th century that tomatoes were cultivated as vegetables in Europe, but the development was very fast. In the second half of this century, tomatoes have become one of the most widely planted and consumed vegetable crops in the world. In 1990, the global tomato production reached 50 million tons.

Development of tomato cultivation in my country Tomatoes were introduced to my country not long ago, around the end of the 17th century and the beginning of the 18th century, when they were introduced to coastal cities in southern my country from Southeast Asia by Western missionaries, merchants or overseas Chinese. Large-scale production of tomatoes in my country began in southern Taiwan and southeastern coastal areas at the beginning of this century. It was not until the 1930s that tomatoes were gradually planted in Northeast my country and North China, and they were mostly concentrated in the suburbs of large cities. After liberation, tomato production became more and more common in the suburbs of large and medium-sized cities in my country. Due to its strong adaptability, rich nutrition, beautiful appearance, and dual-use of fruits and vegetables, it has been cultivated in large quantities in rural areas since the 1960s. At present, tomatoes are one of the most important vegetables in my country; there are many forms of tomato cultivation, and the most common in my country is open-field tomato cultivation, among which open-field spring tomatoes are the main ones, that is, sowing in the last winter or early spring and harvesting in summer. Open-field autumn tomatoes are also cultivated in the south and North China to meet the needs of the autumn market. Since tomatoes prefer higher temperatures and stronger light, in autumn, winter and early spring, open-field conditions cannot meet the minimum temperature requirements for tomato growth. Therefore, with the development of science and technology, the use of greenhouses, plastic greenhouses and other protected facilities for tomato cultivation has received more and more attention. In particular, the success of solar greenhouse tomato cultivation in recent years has greatly improved the supply of tomatoes in the winter and spring markets and achieved a balanced supply of tomatoes throughout the year. China has a vast territory, spanning the cold temperate zone, temperate zone, subtropical zone and tropical zone. When the north is snowing and the ground is frozen, Guangdong, Guangxi and Yunnan are still warm as spring, and open-field tomato production is completely possible. Therefore, by transporting vegetables from the south to the north, the needs of the northern market in winter and spring can be alleviated. However, considering my country's transportation conditions, the principle of local production and local supply still needs to be adhered to.

Second type:

The origin and benefits of tomatoes Tomatoes are Solanaceae plants. Because of their eggplant-like shape, they are also called tomatoes, plums, and kumquats. They are also named tomatoes because they look like red tomatoes and the variety comes from the West. According to historical records, tomatoes are a wild plant that grows in the Peruvian National Forest in South America. Their original name is "wolf peach". Local legend has it that wolf peaches are poisonous and eating wolf peaches will cause bumps and tumors. Although it is bright red when ripe, the red fruit with green leaves is very beautiful and attractive. But just like the colorful mushrooms are highly poisonous, people still stay away from it. No one dares to eat it, but treats it as an ornamental plant. In the 16th century, a British duke traveled in South America and liked the ornamental plant tomato (wolf peach), so he brought it back to Britain as a treasure and presented it to his lover as a gift of love to express his love. Since then, the names of "love fruit" and "lover fruit" have been widely circulated. But people planted tomatoes in the manor and gave them to their lovers as gifts symbolizing love. Generation after generation, no one dared to eat tomatoes.

Until the 17th century, a French painter had repeatedly depicted tomatoes. Faced with such beautiful and lovely but "poisonous" berries, he could not resist its temptation, so he had the idea of ​​tasting it himself. Therefore, he risked his life to eat one, and found it sweet, sour, and sour with sweet. Then, he lay on the bed waiting for the arrival of the god of death. But a day passed, and he was still lying in bed, staring at the ceiling with bulging eyes. How come? He ate a tomato as bright red as a poisonous mushroom and didn't die! He smacked his lips, recalled the great taste of chewing tomatoes, and told his friends the news that "tomatoes are non-toxic and can be eaten", and they were all stunned. Soon, the news that tomatoes were non-toxic shocked the West and quickly spread around the world.

Since then, hundreds of millions of people have enjoyed the delicious food brought by this "daring to be the first in the world" warrior. Later, someone analyzed the composition of tomatoes and proved that it contains multiple vitamins and is a very nutritious food, so they moved it out of the park and into the vegetable garden. In the 18th century, Italian chefs used tomatoes to make delicacies, which were colorful and delicious, and the guests praised them. Tomatoes finally made it to the table. Since then, tomatoes have won the love of everyone and are known as red fruits, golden apples, rubies, and love fruits. Tomatoes have been introduced to China for about a hundred years. In 1983, Chinese archaeologists discovered tomato seeds in an ancient tomb of the Han Dynasty in Fenghuang Mountain, Chengdu, which shows that China had cultivated tomatoes two thousand years ago. At present, tomatoes, as a fruit and vegetable, have been proven by scientists to contain multiple vitamins and nutrients. For example, tomatoes are rich in vitamins C and A as well as folic acid and potassium, which are the main nutrients. In particular, the lycopene it contains is more beneficial to human health, while some fruits such as watermelon, grapefruit, and apricots only contain a small amount of lycopene. Of course, people call tomatoes "love fruit" because this fruit really has the same effect as love and can make girls more beautiful! We can see that loving and science-savvy mothers often let their children eat more tomatoes.

Recently, according to the Journal of the National Cancer Institute, some American medical experts have found that eating more tomatoes has a strong anti-cancer effect, even for stomach cancer, colon cancer, rectal cancer, oral cancer, breast cancer and uterine cancer. This is because tomatoes contain an antioxidant, lycopene, which has the effect of reducing the incidence of cancer. At the same time, it also has a variety of beneficial compounds. The complex interaction between them enhances the anti-cancer ability of tomatoes.
