Without rice, what will humans eat?

In the future, the world population will increase at a very fast pace and scientists fear that there will not be enough food to feed humans. And they are making food for rice.

Human foods can be used instead of rice in the future

Scientists are looking for ways to use high technology to produce food on a large scale without losing too much time and materials. Currently scientists have achieved some initial results such as artificial meat, dried food, protein-based pests, and much more.

Scientists estimate that the world population will quickly reach the 8 billion mark and food will be a huge problem, the food industry will begin to exhaust all resources to produce to ensure supply. application. That same action will continue to destroy the environment more quickly. Fortunately, thanks to the development of science, we have found a number of ways to overcome the food problem and still provide people with enough food of natural origin with adequate nutrition. And below are some of the achievements scientists have made.

3D printed pastry with high detail

Founded in 2014, 3D Systems Technology is one of the pioneers in the application of in3D technology to produce food. Currently, they have developed two prototypes of feed printers, ChefJet and ChefJet Pro, with the ability to create high-quality pastries. Earlier this year, 3D Systems teamed up with Hershey to develop CocoJet printers. As of now, these models have not yet been commercialized but clearly, its potential is huge for the future confectionery industry.

3D printers can customize materials, self-decorate dishes

Foodini is a 3D printer developed by Natural Machines. It allows you to create your own discs with the beautiful layout that users want. Users simply need to prepare all kinds of ingredients, put them into the machine and choose shapes in the pre-programmed list. After that, the machine will manually adjust the printing layers to create the final dish with the layout that the user wants. Currently, this machine only stops at the level of food decoration on a small scale but we can use it to create beautiful fast food dishes, taste and ensure health.

Foods "grow fast" and can be used immediately

Designer Chloe Rutzerveld who is working on a project called Edible Growth also aims to create food with 3D printers . Her idea was to print the seeds, sprouts and yeast into the same " product ". It will then grow up quickly and people can use it as soon as possible. Although the project only stopped at experimental prototypes, this is a quite promising idea, helping to limit the dependence on the cultivation process, reducing the cost of transporting and supplying food, while reducing the amount Extravagant food and provide fresh, clean food for people.

Dry food

High pressure treatment (HPP) is an industrial technique, although it does not use heat and chemicals but still kills bacteria, helping to extend the shelf life of many foods. This is a common way that is applicable to fresh foods, but requires a lot of expensive, large equipment. On a small scale, ordinary users can use commercial dryers to deliver fresh foods into snacks, dried herbs, dried cows or some other dry food that can be stored for a long time. .

Currently, these devices are being marketed at $ 35 and applied by many families around the world to reduce dependence on frozen foods, fast food outlets, . Some products can be consulted on Amazon. In addition, some people also homemade solar energy systems to dry food, you can refer here.

Farming on the roof

Perhaps this idea is quite familiar to all of us. Utilizing the roof for cultivation not only takes advantage of available resources, can create food supply on a small scale but also has many other benefits in terms of landscape, living environment, . Currently Many households around the world, including in our country, have started using this approach, especially residents in big cities. Even in the United States, two agricultural companies Grange and Gotham Greens have applied this model on the roof of many different buildings in the city, helping to reduce the need to use air conditioners, thereby saving electricity. consume.

Planting trees in the fog

What if the situation cannot be planted on the roof? A technology firm in New York, USA created GrowCube - a cage planted in fog. This device will use steam to supply the beds to the inner layers and, according to the company, will save 95% of water demand compared to traditional cultivation methods. All water supplies, nutrients, etc. for plants are controlled by computer, can be placed inside the house. The company revealed that GrowCube also has a faster growing period than usual, about 4-6 weeks as the strawberry plant is large and can grow many different types of vegetables and fruits, growing up to 28 same lettuce plants. at.

"Bacon under water"

Algae (especially seaweed) have been used for a long time and even by people in many countries around the world. However, this seems to be a side dish, but in the future, when the supply of food is scarce, this may become one of the candidates to become the main dish in the human menu. In the latest transformation, researchers at the Oregon State University's Food Initiative found a solution.

They have bred and successfully cultivated a seaweed strain called dulse - with the ability to grow faster than the natural version, containing a variety of minerals, vitamins, antioxidants and proteins. More nicely, this seaweed when fried will smell similar to bacon.

Food from insects

Many insects have a high nutritional content when used as food for humans. Some countries have a tradition of processing food from insects and according to statistics, up to now, 80% of the world are constantly eating insects. Typically, crickets are insects that are high in protein, iron and have a lower level of environmental damage than meat or poultry products. In the United States, some companies have started producing insect products on an industrial scale. They provide live insects for pets, crushed powders, frozen insects or dried. Especially Exo has created protein bars derived from crickets for humans with grass-like taste.

Artificial meat

Not everyone likes to eat insects but if it's meat, everyone can eat it. However, traditional farming does not always ensure sufficient supply of meat for human consumption and therefore, researchers always seek to produce meat. Since 2008, Professor Mark Post at Eindhoven Polytechnic University has begun a project to create "in vitro meat" . His method is to take tissue samples from cows, then cultivate cells to achieve the desired meat.

In 2013, the project created a hambuger with artificial beef. This is a very encouraging success, but its price is not cheap: $ 325,000 each. However, the research team believes that production costs will be greatly reduced in the future. According to research conducted by scientists at Oxford University, the way to produce artificial beef can cut 99% of space demand compared to traditional breeding methods. Of course, now all are still being studied.

Liquid food

When food sources become scarce, what people care about is the nutrients that people need and which way to consume is easiest. Many food companies around the world begin to look for liquid foods to replace regular meals. Rosa Labs in the United States has launched a solution called Soylent - a mixture of powdered and mixed drinks to replace regular meals while ensuring nutrition. Similarly, Ambronite is also a liquid food and is claimed to be of organic origin. Although this idea can provide nutrition to many people but still limits the impact on the environment, many argue that this approach is not a substitute for "real food" in the long term.

Meals on orbit

In the future, the population will not only increase on Earth but also increase in the universe. It sounds a bit fanciful, but maybe people will live on big space stations or on other planets? Since the end of last year, NASA has begun to introduce the Veggie system to conduct a series of aerial plant experiments . In the first experiment, they planted Outredgeous lettuce seeds in " clay-filled " pillows placed side by side.

The goal of the project is to check the operation of this planting system, and check whether the level of bacteria in the vegetables grown is safe for humans. In March last year, NASA continued to experiment with the third planting of Tokyo Bekana cabbage with Veggie system. Based on the results of the experiment, the researchers will refine the design of the "pillow ", fertilizer, crop type and a number of other factors that help the plant grow well, promising to provide food and animals. entertainment for astronauts on space in the near future.
