Chapter 131 How to store food


    After the evolution of Blue Star microorganisms, the difficulty of preserving food has increased significantly. Humans have thought of many ways to extend the shelf life of food.


    Xia Qing used the method of drying first and then draining the air vacuum pack is a commonly used low-cost food storage method.


    This method only separates the impact of "aerobic bacteria" and the abnormally active bacterial species on food in the elements, but cannot inhibit the toxins produced by "aerobic bacteria".


    Even for storage-resistant grains such as unshelled wheat and corn, the maximum shelf life of this method is only three months.


    Three months later, even though the food still looks intact, the toxins produced by the evolutionary anaerobic bacteria have spoiled the food.


    Evolved anaerobic bacteria produce a variety of toxins, including one of the most toxic biological toxins after the evolution of Blue Star creatures - Evolution Botox.


    Evolutionary Botox will not die if it is boiled in boiling water for several hours, so it is not someone who is about to starve to death. No one will use his life to fight the evolutionary bacteria.


    In addition to this simple method of storing food, there are several methods with high cost and good effect. The most commonly used one is the food storage warehouse.


    Storage bins are built in planting and breeding centers in the safe area to store food. The storage warehouse can extend the shelf life of food, and the main grain crops can be extended to more than one year. Onions, potatoes, sweet potatoes, eggplant and Chinese cabbage can have shelf life of more than three months in the storage warehouse.


    It is already amazing that it can still achieve such storage time after the evolution of microorganisms.


    Xia Qing is not a technical worker and is not qualified to participate in the construction of the storage warehouse. So she has not yet figured out the operating principle of the food storage warehouse. She only knows that the storage warehouse needs to meet two basic conditions: one is to filter out the harmful elements in the air, and the other is to control temperature and humidity.


    The destructive power of blue star microorganisms is proportional to the content of the destructive element in the atmosphere. After the destructive element reaches a certain concentration, the destructive power of microorganisms even shows an exponential upward trend.


    It’s okay to control temperature and humidity. It’s very difficult to filter the harmful elements in the air, so the cost of food storage warehouses is very high, and the cost of maintaining the operation of the storage warehouse is also frighteningly high.


    Before getting the Yishi, Xia Qing never thought about storing food in his territory for a long time. First, because she doesn''t know how to repair the storage warehouse, she doesn''t want to find someone to repair it. Second, because of the cost issue, it''s not worth it to build the storage warehouse for the sake of the three melons and two dates she planted or collected.


    Another very important point: At the agricultural product trade fair, Xia Qing overheard Tang Zhengrong’s introduction to Huang Jie, the territorial management minister of Huicheng General Base, that the planting area of ??all the territories of Huisan is 1,358.6 acres.


    How do you get this number with zeros and wholes?


    Xia Qing has been living in the territory for half a year, and the Territory Management Department has not sent anyone to inspect or measure the planting area in Territory No. 3, and Xia Qing has never heard of them measuring the planting area in other territories.


    If you can obtain such detailed data without field surveys, there is only one possibility left: the data was obtained by the Territory Management Department through satellite measurements.


    The cosmic gamma ray storm in the early years of the natural disaster destroyed all the mid- and low-orbit satellites of Blue Star, and only a few high-orbit satellites were left. After the natural disaster, countries were working hard to resume communications, and Xia Qing heard several news of China successfully launching satellites through the radio.


    Since the base can measure the planting area of ??the territory with satellites, it can monitor every move in the territory. This is why Xia Qing is the only one in the territory. She is still careful and concealed when she goes to get spring water.


    Although she is only one of the inconspicuous lords in the 200th territory of Huisan Base, the sudden addition of multiple solar panels and building food storage warehouses in her territory will definitely attract the attention of the lord management department.


    Xia Qing just wants to live in a low-key and high-quality manner, and doesn''t want anyone to pay attention to her, so she is unwilling to make big moves.


    Now, she has Yishi, which solves the biggest problem of food storage. Just dig a cool and dry cave, prevent moisture, insects and bacteria, and store food.


    The shelf life of food stored in this way is longer than that of vacuum packaging!


    There are so many mountains in her territory, isn’t it easy to dig a cave?


    Xia Qing happily ate the ground fruit, put out detailed pictures of the third territory and the third district of the 49th Mountain, and began to select the site.


    These two drawings were exchanged for vegetables and Zhong Tao. The map of No. 3 was drawn by herself, and the map of No. 49 Mountain and District 3 was drawn by Luo Pei. The crops she planted and the native edible plants found in the territory and the three zones were marked with pencils on the corresponding locations of the map.


    It can be said that these two pictures are her treasure maps exclusively.


    Xia Qing first added the location of the three pieces of ground fruit, and then looked at the more and more small dots, circles or small squares on the drawings, and felt a lot of accomplishment.


    Because these are food, in natural disasters, nothing makes people feel safer than food and weapons.


    The more than 1,500 acres of forests and arable land in the picture are all hers. She can dig wherever she wants to dig the cave, as long as the depth of the cave does not exceed 30 meters.


    Because it exceeds 30 meters, it will damage the internal structure of the mountain and may affect the most valuable survival resource she has: pollution-free spring water. Xia Qing hesitated between the third area and the buffer forest for a while, and decided to dig the cave in the western buffer forest.


    Although the third area of ??Mountain No. 49 belongs to her, the altitude is higher than that of the buffer forest and it is easier to control the temperature. But Xia Qing was worried about putting food in places where she could not see or hear it at any time.


    After the site selection is completed, digging a cave is a trivial matter for Xia Qing, who has tools and strength.


    There is no hurry to deal with the most critical "technical means" of preserving food - making Yishi protective shells.


    After carefully studying the information sent by Luo Pei, Xia Qing, who had three months of experience in blacksmithing, found it difficult.


    To make a protective shell of Yishi, you need to melt the gravel screened out in the surface of Yishi and the soil near Yishi at high temperature, then add a certain proportion of iron, carbon, silicon, manganese, nickel and aluminum, and melt it into a shell of a certain thickness.


    Xia Qing took out her tool kit and looked at the supplies she had accumulated over the years. She has iron, carbon, silicon, aluminum, manganese and nickel.


    Xia Qing took out his cell phone and sent a message to Zhong Tao.


    Zhong Tao quickly replied: No problem, why do girls want these?


    Xia Qing replied: My machete is broken, it is too expensive to take it back to the safe area to repair it, so I plan to recast it. I have worked in the ironworking shop in the safety area and have a little understanding of ironworking skills.


    Zhong Tao, who had just walked into the military cafeteria in the safe area, was stunned for a few seconds before typing and replying: Girl, is there anything you can''t do?


    Xia Qing hehe, put the phone back in his pocket.


    "Why don''t you go to get food? Report your itinerary to your wife?" The brothers in the same camp came over with a plate of food. Seeing Zhong Tao standing in a daze, he asked casually.


    Zhong Tao came back from getting a meal and asked his comrades around him, "Do you think a woman who can farm, build houses, and make irons still need a man?"


    Zheng Kui knew who Zhong Tao was talking about when he heard this, and he didn''t say anything. The brother next to him hehe, "It''s not whether she needs to find a man, is there a man who dares to marry such a woman? Do you dare?"


    Zhong Tao''s head was shaking like a rattle, and he didn''t dare to think about it anymore, so he kept his head busy.


    In the territory of No. 3, Xia Qing first changed the two distinguished guests at home to clean drinking spring water, then listened to the radio and took the chickens that had already been in the cage and put them into the tool room before he started to make dinner for himself and Boss Yang.


    The food was greasy at noon, so Xia Qing decided to eat something light at night. Mung bean and rice porridge, white flour cakes, cold vegetables, chopped pepper and bird blood and a few pieces of roasted egrets, all of them are alive.


    The boss of the sheep is mixed with young Chinese toon leaves and grass to compressed rations. The green light alfalfa and perilla bloomed and smelled amazingly. Now, let alone eating, even passing by, Xia Qing and Yang Lao would like to take a detour.


    After cooking, Xia Qing stood in the room and shouted loudly, "Boss, let''s have a meal."


    The boss of the sheep lying in the sheep shed chewed heavily, and in a few seconds, he completed the whole set of movements of washing his feet, rubbing the grass, opening the door and putting on the house and squinted at Xia Qing.


    Where is the meal?


    Xia Qing took out its rice bowl and pretended to be disappointed, "Boss, after your friend comes, you will not stick to me anymore. I am very disappointed."


    Lost, what is that thing? Is it delicious? Boss Yang''s eyes only followed the rice bowl.


    Xia Qing, who was playing the piano of the sheep, was speechless, put down the rice bowl and rubbed its sheep''s horns hard, "You have no conscience!"


    The lights cannot be let out at night. Xia Qing closed the security door, pulled down the blackout curtains, turned on the headlights, went to the kitchen to wash his hands, and brought his food to the dining table, happily shouting, "Dinner!"


    The brain area evolution wolf amber eyes lying in the sheep shed stared at the closed security door for a while before slowly closing it.
