in August this year, Ms. Fu of Ji'nan bought four tomatoes at the farmer's market at the door of his home, and after eating three of the fry on the same day, the rest of the day was left. One of them was forgotten in the kitchen.
until September, when Ms. Fu saw the tomato again, she was more than 30 days away from the purchase. However, Ms. Fu was surprised that the tomato was not only not damaged, but the skin was still bright and color.
out of curiosity, Ms Fu recorded the change process of Tomato in her circle of friends from that day. This record is two months. By the end of the day, tomatoes had spent 79 nights at the Fu's house, and many people who had seen the friends circle of MS Fu were all exclaimed, what was this everlasting tomato made?

56 days
70 days
79 days
to verify how many days
Ms. Fu told reporters that at first, she was just because See the tomato for a long time did not put bad, feel very curious about a circle of friends, I did not think that a record is two months, 79 days of tomatoes have not broken, now I would like to know how many days the tomato can put.
is so curious about the tomatoes, probably because tomatoes are not stored in any cold storage and are completely placed in natural conditions.
Fu Ms. Fu recalls, when the original purchase did not feel anything unusual about tomatoes, but now it is very subtle. When you buy it, the color of tomatoes is red and looks nice, but the flesh is very hard, there is no flesh of the past persimmon, and the feeling is also felt when fried. It's very hard. It's not as green as white tomatoes.
in order to verify the storage time of the tomato, Ms. Fu bought a tomato in the middle of the way. I bought two tomatoes specially to do the experiment. One of them came back about 10 days or so, but the other was not bad for a long time. So far, the tomato has been preserved for nearly 40 days.
Ms. Fu said, no matter how the tomatoes were experimented and tomatoes had been placed for 79 days, their common feature was a long time. The tomatoes were still in good condition. Not only did they have no signs of mildew, but even the skin was intact. There was no damage and atrophy, and the hardness did not change. According to this situation, I think that tomato should be put on the 100 day should not be a big problem.
people feel
fruit and vegetables longer than before,
Fu Ms. Fu sent to the friend circle of tomatoes caused by a lot of people's attention, the records of these days have been kept friends through a variety of ways to greet the Fu MS Fu tomato, see the tomato for so long time not bad, are very curious. .
in October 31st, reporters interviewed a few people who bought vegetables at random in the farmer's market. Several people said that although there was no exact time to measure the storage of other vegetables in the home, it was generally felt that the present vegetables and fruits were longer than ever.
Ms. Wang told reporters that tomatoes bought at home had been stored for a month because they forgot to eat, and there was nothing unusual about eating them.
now, there is a lot of time for the storage of a lot of food, I bought the baby food at home for more than 20 days, even the leaves are not bad, Ms. Zhang also said that some of the vegetable storage time has become very long, before the home of the food for two or three days do not eat is bad.
vegetable farmers say
may be the
reporter of
a reporter who told reporters that he has been planting land for twenty years, but never heard of tomatoes for so long. At home, tomatoes can not be sold out of the day, at most four or five. Days, if sent out, it will pick up a few days in advance, but it can only extend for a few days, and it will not exceed half a month at most.
for a long time for a tomato, Mr. Lu also felt puzzled. It was impossible to store it for so long in natural conditions. It was possible to keep it in a cold storage for a month or so, even if it could not be more than 70 days.
Mr. Zhao is a vegetable farmer in Weifang. He has three big sheds in his family. Every year, tomatoes and cucumbers are mainly planted. The tomatoes of their own family have to be taken lightly. It is some kind of vegetable peddler to come up with a variety of ways to extend the sale time for the benefit. They take off the ripe tomatoes in advance, and make them ripening after the potion. Although the color has changed, they are not well done, but the color of the tomato is good and can be stored for a long time, so the sales are good.
don't worry about
a professional agency to test
a staff member of the Shandong Academy of agriculture, telling a reporter that at present, the storage time of tomatoes is a long time, mostly because the tomatoes are not mature when they are picked, but they have never heard of it for such a long time, the staff member told reporters There is a great relationship between the preservation of fruit and vegetable and the storage environment. If it is placed in a cool, dry place, the life of fruits and vegetables will be extended. Because there are certain sealing conditions, the carbon dioxide produced by the fruits and vegetables can inhibit the respiration. The persimmon is a crop all the year round. Keeping fresh for a long time does not mean much to prolong the shelf life, but if you worry about soaking the water, you can go to a professional institution for testing.
is technically difficult to store
more than 70 days hard to store
Liu Kuizhu, the chairman of the Venus Agricultural Technology Development Co., Ltd., said that the long-term storage of tomatoes is not related to the selection of transgenic plants and seeds. The main link is in the process of transportation, the freshness of the fruits and vegetables is very short, and it can be long. The main reason for the preservation is to use preservatives, such as formaldehyde, to prolong the transport cycle, but the reagent has a strong volatility, almost as volatile for a period of time, and it has not been heard for so long.
Liu Kuizhu said that the company had done experiments with tomatoes, and there would be corruption about 7 days after picking. If stored at the constant temperature storage, it could prolong the life of 3-5 days, but last year there was a new variety of drought resistant tomatoes, which was characterized by the skin. Thick, hard, fried is also very difficult to stir fry, storage time is longer than ordinary tomatoes, and later to the market to find consumers do not like, soon changed to do not do experiments, so can not determine how long can be stored. However, whether it is a variety or preservative, it is very difficult to store more than 70 days technically. If the consumer is not at ease, it can be identified by a professional organization.
Ms. Fu feels a bit of trouble for experts and industry experts to identify professional institutions.
vegetable farmers teach you to pick tomatoes
for how to identify different kinds of tomatoes, many vegetable farmers are very subtle and difficult to identify, Mr. Zhao said, even if they have been growing tomatoes for many years, at first glance, it is difficult to distinguish, but generally, mature tomatoes are larger, and the outer skin is better. It is thin and pink, and the fruit part is green. If the tomato is very red but very hard, especially the fruit part, if the whole tomato is very red, but the fruit is white or yellow is usually ripening, this kind of tomato is not very recommended to buy.
