Hello everyone, welcome to watch the science popularization pattern of this issue.
Speaking of tomatoes, everyone will certainly not be unfamiliar, as a national vegetable on our daily table, can be eaten raw and cooked, can be salted and sweet, and its most famous dish is tomato scrambled eggs, it can be said that most of the Chinese have eaten, and the Chinese people's love for tomatoes is also famous, since 1995, China's annual output of tomatoes ranks first in the world, but nowadays, many people have found that the tomatoes we buy are more and more difficult to eat, but on the contrary, The tomatoes on the market now are rosy and full, but they no longer have any taste, why is this?
And for this problem, it is not only those of us who think so, some scientists even went out of their way to investigate and analyze the reasons for it, after analyzing more than four hundred kinds of tomatoes, only to find out that it is because the current tomatoes are different from the previous tomatoes, that is, they began to commercialize, in order to sell it to the whole country, we must consider its transportation and storage problems, after many generations of cultivation, the current tomatoes are thicker than before, the flesh is harder, and even the juice has become less "stone tomatoes" In addition, in the current tomato, some genes that control the flavor of the tomato are missing, resulting in it not being so attractive.
Secondly, in order to meet the market demand, people in the selection of tomatoes, will choose some of the appearance of more rosy and full, so many tomato farmers in order to meet the needs of the market, generation after generation to cultivate these appearance looks more ruddy and beautiful tomatoes, thus ignoring those key chemicals that determine the taste of tomatoes, which leads to the tomatoes are now bigger than one, one is more rosy than one, but the taste is getting lighter and lighter, tasteless, like chewing wax; of course, This is also some of the things that there is no way, because compared to the previous soft tomatoes, the hard fruit type tomatoes on the market are now more resistant to collision, easy to preserve, can withstand the collision that occurs during transportation, resulting in fragmentation, and to a certain extent to avoid reducing the farmer's yield, and the soft fruit type tomatoes although the taste is better, but it is not easy to store and transport, so it will be slowly eliminated by the market, can only say that fish and bear paws can not be both, how do you look at this?
Well, the popular science knowledge about this issue ends here, thank you for the careful reading and support of all partners, and finally play a brain teaser with you, what is the best way to avoid motion sickness?
