Wei Renshi unscrewed the other cans one after another, put them in front of Li Chun and Jiao Haiqing, and let them taste them one by one, Li Chun and Jiao Haiqing tasted each other, Li Chun sighed: "Brother Renshi, this greenhouse is really a good thing, don't say it's me in the past, even if it is Your Majesty, it is not easy to taste a bite of green vegetables in this winter." Nowadays, everyone can have green vegetables to eat! ”

Wei Renshi still smiled and said nothing, took out another canned meat, opened it and gave Li Chun and Jiao Haiqing a piece each.

"This meat ......" Li Chun and Jiao Haiqing were a little puzzled when they saw that it was not a green vegetable, but they still picked up the meat and tasted it.

Li Chun's eyes lit up and said, "Not bad! Fluffy and delicious! ”

"Lord Chun, Brother Jiao, you don't know that all these things you tasted today did not come out of the greenhouse." Wei Renshi also took a bite of beef and said while eating.

"Oh?" Li Chun and Jiao Haiqing looked down at these things in front of them, and Li Chun asked again: "If it doesn't come out of the greenhouse, where can green vegetables be grown in addition to the hot spring in winter?" ”

"Naturally, it's not next to hot springs." Wei Renshi smiled mysteriously and said to Li Chun and Jiao Haiqing: "To be exact, these things are not grown right now. ”

"Then how can you get such fresh greens?" Jiao Haiqing was even more curious and asked.

Wei Renshi replied with a smile: "These things are actually saved when they are in season. ”

Wei Renshi pointed to the cans in front of Li Chun and Jiao Haiqing, and said, "It's like this bottle of cucumber, which was picked in July." And this bottle of plums, also from that time. This can of meat has been around for almost four months. I made all these things four months ago, and I only came to eat them today. ”

"What?!" Li Chun and Jiao Haiqing looked down at the green vegetables in front of them in shock.

Li Chun stretched out his chopsticks, picked up half of the cucumber, looked left and right, and bit it with his upper teeth, it was really a crisp taste, and he couldn't help but be even more surprised.

"This ...... It's almost four months...... Brother Renshi, how did you let these green vegetables sit for so long, but they are still so tender? Li Chun looked up and asked.

"It's a way to store food, fruits and vegetables." Wei Renshi said: "These things are called canned food. Vegetables, fruits, meat and other foods that cannot be stored for a long time, fruits and vegetables, after cooking, put them in a wide-mouth glass bottle, and then fumigate them with hot steam, after half an hour, seal the bottle while it is hot, and then wrap it with a prepared thin wire while it is hot, and then wrap it with a layer of wax to ensure that it is sealed, and then let it cool naturally. In this way, the food, fruits and vegetables can be preserved for a long time, even in the past six months, when they are opened and eaten, they can still retain their tender taste, and naturally they can also preserve the nutrients contained in these foods, fruits and vegetables. ”

Li Chun and Jiao Haiqing's eyes froze, and they immediately raised their heads, took their eyes off those green vegetables, and stared at Wei Renshi.

Especially Jiao Haiqing, his eyes were full of surprise, he had already guessed Wei Renshi's intention to make these things.

Wei Renshi took out the contents of the can and put it on the plate in front of Li Chun and Jiao Haiqing, and continued: "The sea ship that sailed from Guangzhou will go all the way to Dashi, and even to Daqin. The temperature and humidity along the way are high, so even if the ship carries a large amount of food, it is easy to spoil, not to mention vegetables and fruits. ”

"Vegetables and fruits are as important to the human body as food. If you don't eat vegetables and fruits for a long time, your body will lack many things that you need to maintain your health. Wei Renshi said: "When sailing in the ocean, the most feared thing is malnutrition. If people on board are short of vegetables and fruits for a long time, they are very susceptible to a large number of diseases called sepsis. Once you get this disease, in terms of our medical skills today, it is a mortal disease. This is also the most important reason why they will travel long distances and die for a lifetime. ”

"To prevent it, you need to eat vegetables and fruits. However, vegetables and fruits are often highly perishable and cannot be carried in large quantities over long distances. Wei Renshi said: "And with this thing, this problem has been solved." ”

"Can this thing really keep those fruits and vegetables for half a year?" Li Chun's eyes were solemn and he asked in a deep voice.

Wei Renshi nodded solemnly and replied, "These cans were all made and put away by me three months ago." When I opened it today, there was no trace of the contents that were going to rot and deteriorate. Depending on the condition, if it is not opened, there will be no problem if it is left for another three or four months. ”

"The color is indeed fresh and tender, as if it were freshly picked." Li Chun looked at the contents of the can and said.

"It's not just people on the sea. In fact, these cans can also be used as a supplement to the military rations in the land army. Wei Renshi also said: "People need vitamins provided by vegetables and fruits to ensure the health of the body, the army has traveled a long distance, if you can get these vegetables and fruits in addition to eating military rations, it is not only good for the body, so that the body is healthier, play a better combat effectiveness, but also improve the food, so that the soldiers are in a good mood when eating, and the morale of the army is also better." ”

Li Chun has been in Youjin Wuwei for so long now, and he is often deliberately arranged by Wei Renshi to open a small stove to teach him some military allusions and knowledge, and when he hears this, how can he not understand the benefits of this thing for the army.

"Then these things should not be too difficult to do, listening to what Brother Fang Cai Renshi said, right?" Jiao Haiqing asked suddenly.

Wei Renshi nodded.

Jiao Haiqing clapped his hands excitedly, and said: "Lord Chun, Brother Renshi, I personally went to sea twice this time, and I really saw the scene of maritime merchants. The maritime merchants of our Datang alone are ruthless, not to mention the maritime merchants of other countries. However, the maritime merchants everywhere were worried about this matter. If you really eat these vegetables and fruits, you can not have that kind of strange disease, so why don't we spread this method? After spreading the word, other people can't keep a lot of long-term fruits and vegetables, so we can't take these...... What the hell—"

"Canned." Li Chun reminded.

"That's right! Can! Jiao Haiqing said: "Take these cans and sell them, sell them to Datang, and sell them to other maritime merchants everywhere!" ”

Wei Renshi nodded and smiled: "That's what I mean." ”

The three of them summed up and settled the matter.

was about to celebrate, when he suddenly heard the shouts of the family from outside, and said: "Xiaolang, there are a few guards outside, saying that they are from the East Palace, and they are looking for the king of Guangling County for something important!" ”

Wei Ren sighed in his heart.

Count the season, right now, it's September!
