Space food packaging

space packaged food is unusual

in the boundless space, food and clothing are still the basic elements of human survival. In space, due to weightlessness (also known as microgravity without gravity or microgravity), the microgravity velocity in space is much smaller than the gravitational acceleration g on the earth's surface, which is about 0.0001g. It not only changes, but also checks whether the amplifier unit is normal after troubleshooting the displacement sensor First disconnect the output signal of the amplifier unit Remove the output wiring, and then enlarge it through the workstation to master the waste plastic recycling technology & nbsp; Assist the waste plastic circular economy system builder unit to add a DC input signal, and measure the output of the amplifier unit. After repeated several times, the measured output signal of the amplifier unit becomes a linear change trend, so as to determine the habits and actions of normal earth people in the amplifier unit, and will change the way of eating. In addition, people consume less energy in space than on earth, but in order to ensure a healthy body and efficient work, 12000kj (3000kcal) of energy should be supplied every day. Therefore, space packaged food is extraordinary

in order to ensure the safety of space package food, the United States began to study the safety system of space package food (HACCP system) in the 1960s, and then continued to improve and perfect in the global quality system environment. Subsequently, it was made public at the United States Food Protection Conference (ncfp) in 1971 and became known to the world; In 1973, it was listed in the food safety regulation (21cfr) by the United States; In 1987, nacmcf Committee was established and HACCP guidelines were issued, which began to be accepted by countries all over the world; In 1992, it became the international general food packaging production management system and standard. Now it has become the world's most famous HACCP system promoted by the global food industry. China has begun to implement HACCP certification in the food/packaging industry

types of space packaged food

the general requirements for space packaged food are high nutritional value, reasonable collocation, small and light volume, convenient to eat, and cannot be scattered, so as to prevent floating in space. There are mainly the following categories:

semi solid packaged food. This kind of food is packed in a metal hose. When eating, open the mouth, insert a hard plastic tube, and gently press the metal tube with your hand to enter the mouth. This kind of packaged food is convenient to eat in a weightless environment and will not float in the cabin. It is very safe and reliable. The types of food include minced meat, jam, caviar, etc. the nutritional composition is reasonable. It can also be eaten wearing pressure clothes. It is suitable for short-term aerospace

filling viscous food. This kind of packaged food is similar to canned food we eat on earth. We can cook and prepare small pieces of meat, fish meal, chicken and duck. The soup is thickened with starch and then put into cans for disinfection and sealing. This kind of food has high water content, delicious taste, convenient eating, safety and hygiene, and will not float. It is very popular with astronauts

dehydrated bagged food. This kind of food is cooked on earth. After being dehydrated at low temperature and low pressure, it is put into plastic bags for sealed storage. Before eating in space, water is added with a water injection needle, and it can be eaten after a few minutes. This kind of food is not convenient to eat and tastes bad

one mouthful packaged food. This is a space convenience food in weightlessness. It is very convenient to eat one piece at a time. Birds, meat, bread and other food are made into round, square, triangle, rectangle, oval and other shapes on the ground, and packaged with plastic film, which is the size of chocolate candy. It is very convenient to eat in space without falling debris and floating

packaged drinks. Drinking drinks in space is more troublesome than if you have other questions. If you pick up the cup and drink it like on earth. Generally, orange, pineapple, cocoa, coffee and other beverage powder are packed in aluminum-plastic composite bags. When drinking in space, use a water injection needle to inject ml of hot water or cold water from the water injection nozzle, which is the second largest material of aluminum, and then insert it into a plastic tube for absorption. At present, space drinks include lemon juice, orange juice, coconut juice, etc

space staple food (packaged food). The staple foods in space include rye bread, chicken noodles, fruit omelet, sausage pie, stewed meat rice, cream pudding, etc; Meat includes smoked turkey, roast steak, tuna, ham sausage, etc; Vegetables include green beans, asparagus, dried cauliflower, braised potatoes, etc; There are one or two hundred kinds of fruits, such as bananas, pineapples, oranges, apples, etc., which are really everything in the world. Now the space dining conditions have also been improved, and the dinner plate can be fixed on the table, which seems to have a human feeling

in 1992, China officially launched the manned space project, and China began to study space food and space packaging. According to Su Shuangning, the commander-in-chief of China's manned space crew system, the diet of astronauts' three meals a day is formulated by nutritionists, and the three meals in the morning, noon and evening will not be duplicated in three days. The food is a variety of canned and rehydrated food. Rice and fruits are stored and packaged in a vacuum dehydrated state. They can be rehydrated or heated with heating equipment when eaten. The design requirements of aerospace packaged food mainly include less residue, high thermal energy and easy digestion and absorption. Considering the eating habits of Chinese people, the astronauts were also prepared with foods suitable for Chinese tastes, such as Babao rice, shredded pork with fish flavor, Kung Pao diced chicken and so on. After dinner, there is also a nourishing drink with Chinese characteristics prepared with traditional Chinese medicine. At 11 o'clock on October 15, Yang Liwei began to eat lunch for the first time in space. He enjoyed this special space food by squeezing the packaging bag with his hand while reading a book. In an exclusive interview with CCTV, he said that during the 21 hours of space flight, he had three meals, and there were many varieties (space packaged food) for him to choose from. When drinking water, "there is a soft packaged water with a clip on it. I put the drinking straw in my mouth, open the clip and suck it. After drinking, I will stick the water." This shows the high level and variety of space packaged food in China

according to media reports, China will complete the lunar exploration flight in a relatively short time. I wish China's space food and space packaging more scientific and advanced, and make new contributions to human society
