Discovered a new way to preserve vitamins in food

12.12.2022

Boiling, freezing, drying foods and many other factors destroy vitamins. Therefore, such food becomes less useful.

Scientists from the Massachusetts Institute of Technology have developed a new way to fortify food with vitamin A. This will help improve the health of millions of people around the world.

In a new study, they showed that encapsulating vitamin A in a protective polymer prevents the nutrient from being destroyed during food preparation or storage. Scientists plan to include such vitamins in flour or bouillon cubes.

"We wanted to check whether vitamin A can retain its effect during cooking, and whether it will be destroyed under the influence of various factors," said Anna Jaklenek, the author of the study.

To protect the vitamin from degradation, the scientists mixed it with a polymer to form particles 100 to 200 microns in diameter. They also coated them with starch to prevent sticking. These encapsulated particles were incorporated into flour and bouillon cubes. It turned out that foods enriched with vitamin A remained useful even after boiling and under the influence of high temperatures.

"Food fortified with our vitamin A can provide the recommended daily allowance, even after prolonged storage or exposure to high temperatures," adds Wen Tang, co-author of the study.

The existence of an entropy rule for quantum entanglement has been proven 09.05.2024

Quantum mechanics continues to amaze us with its mysterious phenomena and unexpected discoveries. Recently, Bartosz Regula from the RIKEN Center for Quantum Computing and Ludovico Lamy from the University of Amsterdam presented a new discovery that concerns quantum entanglement and its relation to entropy. Quantum entanglement plays an important role in modern quantum information science and technology. However, the complexity of its structure makes understanding and managing it challenging. Regulus and Lamy's discovery shows that quantum entanglement follows an entropy rule similar to that for classical systems. This discovery opens new perspectives in the field of quantum information science and technology, deepening our understanding of quantum entanglement and its connection to thermodynamics. The results of the study indicate the possibility of reversibility of entanglement transformations, which could greatly simplify their use in various quantum technologies. Opening a new rule ... >>

New method for creating powerful batteries 08.05.2024

With the development of technology and the expanding use of electronics, the issue of creating efficient and safe energy sources is becoming increasingly urgent. Researchers at the University of Queensland have unveiled a new approach to creating high-power zinc-based batteries that could change the landscape of the energy industry. One of the main problems with traditional water-based rechargeable batteries was their low voltage, which limited their use in modern devices. But thanks to a new method developed by scientists, this drawback has been successfully overcome. As part of their research, scientists turned to a special organic compound - catechol. It turned out to be an important component that can improve battery stability and increase its efficiency. This approach has led to a significant increase in the voltage of zinc-ion batteries, making them more competitive. According to scientists, such batteries have several advantages. They have b ... >>

Alcohol content of warm beer 07.05.2024

Beer, as one of the most common alcoholic drinks, has its own unique taste, which can change depending on the temperature of consumption. A new study by an international team of scientists has found that beer temperature has a significant impact on the perception of alcoholic taste. The study, led by materials scientist Lei Jiang, found that at different temperatures, ethanol and water molecules form different types of clusters, which affects the perception of alcoholic taste. At low temperatures, more pyramid-like clusters form, which reduces the pungency of the "ethanol" taste and makes the drink taste less alcoholic. On the contrary, as the temperature increases, the clusters become more chain-like, resulting in a more pronounced alcoholic taste. This explains why the taste of some alcoholic drinks, such as baijiu, can change depending on temperature. The data obtained opens up new prospects for beverage manufacturers, ... >>

Prostheses that feel heat and touch 08.06.2018

3D printing and the latest robotic developments have already made prostheses more comfortable and functional, but now they will have a quality that was previously unavailable - sensitivity.

A team of researchers from Stanford and Seoul Universities has developed an artificial nervous system that can process information from the outside world like the human body. This will restore the sense of touch in amputees and give the robots some type of reflex ability.

“We take the skin for granted, but it is a complex system of perception, signals, and decision making,” says Zhenan Bao, professor of chemical engineering and member of the research. “This artificial sensory nervous system is a step towards creating skin-like sensory neural networks.” for various applications."
