Chocolate that doesn't melt

09.01.2016

Barry Callebaut claims to have created a technology that beats the melting of chocolate. And they have already begun to produce miracle bars that retain their shape and consistency at temperatures up to 38 ° C - 4 ° C more than ordinary chocolate can withstand.

The company's management instructed its specialists to develop heat-resistant chocolate in order to further develop new markets. The new chocolate is planned to be sold in countries with a warmer climate - in the Middle East, Asia and Africa. The company notes that chocolate is less popular in these regions precisely because of the high cost of delivery. Meanwhile, among the advantages of heat-resistant chocolate are just simplified conditions for transportation and storage.

The idea of making chocolate unaffected by heat is not new; similar technologies have been developed by several companies for decades. For example, Hershey, a company that has been selling "tropical bars" since World War II, says its heat-resistant chocolate will go on sale within two years.

And Nestle experts believe that it is possible to create chocolate that can withstand heat up to 40 ° C. As early as 2012, Cadbury's laboratory staff developed a chocolate that retains its shape at this temperature for more than three hours.

Hershey previously announced plans to launch chocolates infused with the amino acid L-theanine found in green tea. This decision was made after a study that proved that dark chocolate and green tea - the perfect combination to increase concentration.

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 ... >>

Virtual Solis plans to build large photovoltaic panels in orbit, using Starship to deliver the necessary equipment. However, one of the key challenges ... >>

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, ... >>

Diesel smoke harms the heart and blood vessels 05.02.2020

Dirty air is harmful to health - this is evidenced by medical statistics: those who breathe air with a large amount of industrial and automobile pollution are more likely to suffer from various diseases, including Alzheimer's disease.

Researchers from the National University of Kapodistrias of Athens equipped a special room in which it was possible to control the composition of the air, and filled it with air with combustion products of diesel fuel - in the amount that can be found in the center of a densely populated city (burned diesel accounts for about 50% of all pollution urban air). For comparison, the same room was filled with clean air. The participants in the experiment, forty people without any cardiovascular problems, were divided into two parts: one two hours they breathed smoky air, the other - clean air. A month later, both of them returned to the laboratory, but now they changed roles: those who used to breathe clean air now breathed diesel exhaust, and vice versa.

The state of the heart and blood vessels was assessed by a number of parameters: the activity of protein C was measured, which works as an anticoagulant in the blood, reducing the likelihood of blood clots; the activity of C-reactive protein, one of the main markers of inflammation, was measured; blood vessels were measured to what extent they can expand under the influence of increasing blood flow, how elastic or rigid their wall is, etc. It turned out that even two hours in a diesel atmosphere is enough for cardiovascular parameters to change, and not for the better side.

In those who breathed dirty air, the activity of the inflammatory protein increased (smoking participants in the experiment had more of it than non-smokers). The activity of the fibrinogen protein, which is necessary for blood clotting, also increased; at the same time, the activity of the anticoagulant protein decreased - from which we can conclude that the likelihood of blood clots increased in the vessels. Deviations in the heart rhythm appeared, and the walls of the vessels became less flexible - which, in turn, should affect the blood supply to the organs and the work of the heart. What is especially important, all these changes lasted for a day, although people breathed dirty air for only two hours. But many of us spend in the city center not two hours or three, but more.
