Qingfeng Liuxiang asked with a little surprise, "Really?" You're not fooling me, are you? ”

"What am I lying to you for? Do you expect that after listening to it, in order to test the authenticity, you deliberately buy sour oranges that people can't sell, come back and shake it vigorously at home, and shake it out with a stinky sweat, and in the end you can only eat sour ones? Am I that bad person? ”

"Hehe, you don't look like a good person from head to toe, but as a bad person, you are also a failure, and you actually told such an insidious deed, so how could I be fooled?"

Lu Ming said, "Whatever you like." ”

Qingfeng Liuxiang asked again, "But this sounds amazing, I seem to remember that our chemistry teacher in high school said that it seems to be an underripe apple or a banana that will ripen in a bag or two after a day or two, and what he said at that time seemed to be...... What kind of ethane or what can ripen, but I don't even know about oranges. ”

"I really feel sorry for your chemistry teacher, that's ethylene, that thing can ripen fruits, apples and bananas will release ethylene during the natural ripening process, and if you block the bag to prevent ethylene from escaping, then you will naturally lose quickly; If it's ethane, if you open the bag at that time, it will be like a gas leak at home, then it's really 'over'. ”

Lu Ming said this, in fact, a bit alarmist, because in fact, ethylene is more dangerous, the upper limit of the explosion concentration of ethane is about 16%, and ethylene has to go up to 34%, relatively speaking, ethylene is more likely to explode, but fortunately, the ethylene content released during the ripening process of the fruit is extremely low, although it is more than enough to be used for reverse ripening - it can be barely understood as a catalyst but in fact has not undergone any chemical reaction, and it is now generally believed that ethylene ripening is because it stimulates the respiration of the pericarp cells.

Of course, it's hard to explain such a thing clearly to Qingfeng Liuxiang, after all, she is a girl who has returned all her high school chemistry knowledge to the teacher.

The girl didn't seem to be frightened by Lu Ming's alarmism, "Oh so, the same is true for sour oranges?" ”

"Of course not, I have looked up oranges on the Internet before, and in fact, it can't make oranges sweet, but this can damage the acidic substances in them, in fact, because they are not so sour, so they have the illusion of sweetening."

Qingfeng Liuxiang's eyes widened, looked Lu Ming up and down, and then hurriedly asked, "You even know such a thing, so you must often buy lemons or oranges to eat?" ”

Lu Ming shook his head, "No, no matter what kind of fruit it is, it is difficult to keep it for a long time, and it will be bad in a few days after buying it, I stay in front of the computer all day, how can I buy it often?" And I'm not a pregnant woman with a child, how can I eat sour things, sometimes I go downstairs to buy vegetables and see someone selling cheap grapes and 3 cents a pound of watermelon, but I may buy a little back. ”

"Then you don't usually buy it, how can you know so much about such a thing? You don't do this business. ”

Lu Ming's hand paused for a moment, and after recalling it carefully, he was also a little puzzled, "That's right, even if I usually go out to buy oranges, I will definitely buy sweet, why would I have nothing to check on such a thing when I am full?" ”

Qingfeng Liuxiang squeaked and laughed, giggling and laughing, she seemed to be in a much happier mood, "Oh, you don't have to worry about this, anyway, it's not a bad thing to know this, oh yes, you just said that oranges haven't actually changed to sweet, they're actually not so sour, right?" So, can lemons also be used in this way? ”

This turned Lu Ming down, "This, I don't know very well, but it seems that I haven't heard of any lemon that is sweet." ”

"But the lemon tea sold in some restaurants is really sweet, and then there are dried lemons in the supermarket, and it tastes very sweet."

Lu Ming smiled, "You're just raising the bar, as long as the guests in the restaurant open their mouths, even if it's bitter gourd, he can make sweetness for you, it's a big deal to put more honey, rock sugar or something, this thing is cheap, and when the time comes, you can still sit on the ground and pit your money, as for dried lemons, it's even simpler, are you sure that the sweetness you eat is really the dried lemons themselves, not the powdered sugar on top?" ”

"You're so uncute!" Qingfeng Liuxiang came up with a categorical sentence, "I'll just make an analogy, just come here to say such cool words that spoil the scenery." ”

Lu Ming shook his head helplessly, "Yes, yes, I am indeed not cute, I generously admit it, anyway, it is not the first time I have heard someone say this." ”

Qingfeng Liuxiang muttered, obviously quite dissatisfied with Lu Ming's attitude, and then she said, "Then according to what you said, the lemon itself is sour, but with some seasonings to spice it, it can be sweetened?" ”

Lu Ming thought for a while, Qingfeng Liuxiang likes to raise the bar so much, so he naturally has to speak more rigorously, "In the first half of the sentence, you said that lemons must be counted, I am not a botanist, so I dare not tell you this; But the second half of the sentence, that is naturally the truth, Chinese food culture is broad and profound, the vast majority of dishes, can not be just the taste of the ingredients themselves, just like a boiled cabbage that sounds very simple, the essence is in the water, the delicacy is in the water, not in the cabbage, this is the method that has been handed down for thousands of years, and it is also the chef's decades of hard work and condensation, the taste of the taste, the way of taste...... Well, I suddenly felt that the ancients used 'Tao' to describe taste, which is indeed the essence, saying that it is the satisfaction brought by seasonings, but rather that it is this long-standing culture and the efforts of chefs that have converged into these countless human delicacies. ”

"Blow, you have to blow hard!" Qingfeng Liuxiang looked disdainful, "No wonder people say that those who are close to Zhu are red and those who are close to ink are black, you guy was honest at the beginning, but now he stays with that dead ghost who is not satisfied every day, and he is so oily and smooth, and he also 'said', are you about to cross the catastrophe?" Isn't Thunder going to hack you later? Oh, I'll have to stay away first, or God will hit me by mistake, and I'm shallow in navigation, and I won't be able to stand the test. ”

Lu Ming smiled, hehe, let you lift the bar, now you can't find a place to lift it, right?

Qingfeng Liuxiang said that she wanted to hide far away, but she didn't take action, but continued, "I think you're quite familiar with this...... So, let me ask you......

What do you think is the best seasoning in the world? (To be continued.) )
