RESUMO
Food and nutrition have greatly influenced the effectiveness of space exploration missions. With the development of technology, attention is now being paid more and more to preparing food for the microgravity environment, taking into account factors like nutrient density, shelf life, optimized packaging, preservations, innovations, challenges, and applications. The spectrum of food products is designed to meet the balanced nutritional requirements, reduce hazards encountered by astronauts, and utilize space in explorers during space missions. For the long duration of space missions and, consequently, for human permanence in space, it is crucial to provide humans with an adequate supply of fresh food to meet their nutritional needs. By doing this, astronauts could reduce the health risks associated with psychological stress, microgravity, and radiation exposure from space. Maintaining astronauts' health, happiness, and vitality during long-duration human-crewed missions has recently emerged as an essential and critical research area. The food they eat appears to be an important factor. For short-term space missions, astronauts' food could be brought from earth. Still, for long-term space missions to the Moon, Mars, and other distant missions, which are the current research destinations, they must find a way to eat, such as by cultivating plants or finding other means of survival. Scientists and researchers are attempting to develop novel food production technologies or systems that require minimal inputs while maximizing safe, nutritionally balanced, and delicious food outputs for long-duration space missions that could benefit people on earth. This review summarizes various aspects of space food, including evolution, innovations, technological advancements to prolong shelf life, and astronauts' problems. It also involves current research, including space foods like 3D printing and space farming for a long-term space mission.
