After the draw, Huo Zixuan played against Chi Xiaosheng, and Bai Ming played against Liu Yehan. Pen Fun Pavilion wWw. ｂiquge。 ｉｎfo

For this result, Chi Xiaosheng secretly complained, after all, Huo Zixuan is an eight-grade spirit eater, and his grade is higher than Huo Ziwen's, not considering Huo Ziwen's spirit pupil, his comprehensive strength ranks first in the same year. Liu Yehan was secretly glad that he was also a descendant of the Liu family, and he boasted that his strength was second only to Huo Zixuan, and he was nine out of ten against Bai Ming.

"In this duel, I will give you a dish, this dish may feel very unfamiliar to you, but I will not give you hints, let alone give you specific steps and dosages, you need to figure it out for yourself according to the name of the dish, whether it is success or failure is up to you. Qin Yu said.

Everyone was nervous when they heard this, and they were very clear about the familiar dishes, the amount of ingredients, the proportion of seasonings, the heat and other aspects, almost all the big foods. For unfamiliar dishes, these aspects need to be thought about by themselves, which is a great test of cooking experience, familiarity with ingredients and on-the-spot adaptability.

If it is the King of Eaters and the Emperor of Food, he is experienced and well-informed, and he may be able to become a good person, but for a Eater and a Eater, the experience is insufficient, and it will be even more difficult to become a good person.

Qin Yu's gaze swept over the faces of the four people, and after a moment of silence, he finally reported the name of the dish: "Garlic lemon shrimp!"

Garlic lemon shrimp!

Hearing this name, not only the students in the audience were stunned, but even the old courtyard master and Duan Zhensheng were stunned, they didn't know what Qin Yu would do in advance, and when they heard the word lemon at this time, they all felt a little confused.

The reason is very simple, lemons are not cold tolerant, not resistant to high temperatures, and like a warm environment of about 18 degrees, which leads to the fact that there are no lemon trees planted in Jiang Guo, which in turn leads to Jiang Guo's big food cooking almost does not use lemons, and he is not familiar with lemons at all.

It is true that the lemon production area of the Food Continent is mainly located in the Qi Kingdom and the middle of the area, because the food continent's fresh-keeping freight measures are very backward, so it is difficult for lemons to be shipped to the edge countries in large quantities, and a small number of lemons that arrive through special channels are also special offerings for the royal family and the food palace, and ordinary food can rarely be seen, let alone used.

Therefore, Qin Yu proposed the dish of garlic lemon shrimp, which is not difficult for the big food in the lemon producing area and its vicinity, but it is more difficult for the big food of Jiang Guo, and it is even more difficult for the inexperienced spirit eater.

"Is there any problem?" Qin Yu's gaze swept over the faces of the four people again, his purpose was to stump them, so that he could test their true depth, and now it seemed that the goal should be achieved.

The four of them had different expressions, Huo Zixuan, Liu Yehan and Chi Xiaosheng shook their heads and said that there was no problem, even if there was a problem at this time, they couldn't lose their momentum.

Bai Ming didn't have any ambitions, but raised the question in his heart: "I've heard people say that shrimp and lemon can't be eaten together, otherwise arsenic will form arsenic and poison people, is this statement true or false? If it's true, why do you want to make shrimp and lemon together?"

This question immediately made Huo Zixuan, Liu Yehan and Chi Xiaosheng look sideways, and the three of them chuckled in their hearts, obviously remembering this statement.

The rest of the people looked at each other, is there such a statement? Why haven't they heard it?

Qin Yu secretly bowed her head, Bai Ming was the first to ask this question, indicating that she had been thinking from the beginning, and being good at thinking was exactly the ability that an excellent food eater needed most.

"There is indeed such a statement, and it is indeed reasonable, but do you know what the principle is?" Qin Yu asked.

Bai Ming shook his head: "I don't know, please ask Qin Dashi to solve your doubts!"

"Does anyone know?" Qin Yu looked at the rest of the people again.

The old man stroked his beard and said: "The old man knows something, it seems that there is something special in the shrimp, which can react with lemon and turn into arsenic." ”

"In fact, not only shrimp, but also crab and clam shellfish also contain that semi-poisonous substance, which becomes a complete toxin when it comes into contact with lemons. Qingyi added.

Qin Yu nodded: "Yes, not only shrimp, but also crabs and many shellfish contain an element called arsenic. When a high dose of vitamin C and pentavalent arsenic meet, pentavalent arsenic will be reduced to trivalent arsenic, that is, arsenic trioxide, and arsenic trioxide is arsenic, which is the principle of toxin formation!"

Arsenic, vitamin C, pentavalent trivalent reduction, arsenic trioxide, what are these things? Never heard of this?

Not to mention many young people, even Qingyi, who is rich in five cars, has never heard of it, Bai Ming blinked his eyes, and nodded as if he understood whether he understood or not: "I understand, but I don't understand what arsenic and vitamin C are, and why are they divided into pentavalent and trivalent? Why are trivalent poisonous?"

"These designs are very esoteric knowledge, and you can't say anything clearly, you just need to remember that shrimp and lemons produce toxins because arsenic and vitamin C react," Qin Yu said.

Bai Ming said, "I remember, but since arsenic will indeed be produced, why do we have to do it together?"

Qin Yu smiled: "I just said that it is a high dose of vitamin C, how much juice can one or two lemons produce? How much vitamin C is in these lemon juices? And during the cooking process, vitamin C will be destroyed when it encounters high temperatures, and then it will lose its ability to form toxins." ”

Murong Xue said suddenly: "I remember, Brother Qin Yu, you said that many metal elements mainly accumulate in the heads of shrimp and crabs, as long as the head is removed, most of the metal elements can be removed, arsenic should be like this!"

"Yes, that's a big reason to get rid of the shrimp heads. Qin Yu smiled approvingly at Murong Xue, turned his head to Bai Ming and said, "Now you understand, that statement is too exaggerated, as long as it is handled properly and the dose is controlled, it is safe." ”

"Thank you Qin Dashi for your teaching, thank you Murong Dashi for your teaching. Bai Ming actually thanked Murong Xue as well.

Everyone immediately realized a problem, Murong Xue can know this knowledge, Qin Yu is indispensable, who can stay by Qin Yu's side for a long time, or even become Qin Yu's disciple, not only can his strength be improved rapidly, but he can also benefit deeply from his academic aspects, and maybe he will even be able to become famous in the world in the future.

Sure enough, there are too many benefits to becoming Qin Yu's disciple, Huo Zixuan secretly clenched his fists, he is going to decide this leader, no one wants to rob him!

"Okay, now that you understand, let's get started. Qin Yu waved his hand and took out a basket full of fresh lemons, all of which were produced in the super food system plantation, with excellent quality and freshly picked, with yellow and green colors, bright and round appearance, one head with a pedicle and a green leaf, and a sharp end like a horn, which looked quite attractive.

(It can also be regarded as a rumor for lemon shrimp, don't drink lemon juice and don't eat Vc tablets after eating, by the way, ask for a ticket on the last day of the month~)
