seaweed cheese

20.11.2021

A Singaporean food company has created a real vegan cheese from protein flour and microalgae. It can be eaten solid or melted in the microwave and tastes like cheddar.

Sophie's BioNutrients, a Singapore-based biotechnology company, is committed to sustainable food production, which means it pays special attention to the environmental friendliness of its production. Earlier this year, they announced that they were developing a protein-rich cheese made from photosynthetic microalgae that would be completely free of animal protein. And the other day the company announced that their new product is finally ready. In May of this year, they introduced lactose-free milk from the same algae, and before that, protein flour.

"Microalgae is one of the most nutrient-dense resources on the planet," said Eugene Wang, co-founder and CEO of Sophie's BioNutrients. a lot of protein, and such a vegan cheese contains more nutrients than analogues."

Cheeses without animal protein are already on the market in large quantities, but in most cases their taste leaves much to be desired. The creators of the new product claim that their cheese has a rich taste of protein (umami) and even resembles cheddar.

In addition to algae, this cheese also contains protein flour, which was also previously developed by Sophie's BioNutrients. This vegan product will be produced in two forms - the usual semi-solid pieces and in the form of the so-called "cheese butter" - a lactose-free butter substitute. It can be sliced, melted in the microwave, added to a sandwich or spread on bread. One serving (about 28 grams) of this cheese contains twice the daily requirement of vitamin B12.

A Singapore company grows these photosynthetic microalgae in special bioreactors. In their natural environment, they live in both fresh and salt water - they need carbon dioxide and a source of light to live and feed. These microalgae are an excellent source of amino acids, fatty acids, vitamins, minerals and antioxidants. They are also used in fish feed.

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, ... >>

Cold computer memory 27.12.2012

Researchers at the University of California School of Engineering and Applied Sciences have made significant improvements, significantly advancing the ultra-fast, high-bandwidth computer memory class. This type is called magnetoresistive random access memory or MRAM.

The team called their new development MeRAM. It has great potential for use in almost all electronic devices - smartphones, tablets, computers, microprocessors. You can also use it to store data. MeRAM's key advantage over other technologies is its combination of low power consumption, high read and write speeds, and non-volatility - the ability to retain data in the event of a sudden power outage.

Currently, magnetic memory is made on the basis of technology using the spin of electrons, and not just their charges. This technology (SST) uses electrical current to write data to memory. It outperforms other technologies in many ways, but it requires a certain amount of power, and quite a lot of it, and therefore generates heat when recording. In addition, the volume of such memory is limited by the currents required to record information per unit area.

In the case of MeRAM, the scientists replaced current, which plays a key role in SST, with voltage. This eliminates the need to transfer huge amounts of electrons through wires, and instead uses electrical potential differences to switch magnetic bits and record information. As a result, the computer generates much less heat, making it up to 1000 times more energy efficient. And the memory itself can be 5 times denser - more information is stored in the same physical area, which reduces the cost of transferring a bit.

"The ability to switch nanosized magnets using voltage is an important and rapidly growing area of ​​research in magnetism," said electrical scientist Pedram Khalili, project leader at UCLA. how the devices will operate without the need for an external magnetic field and how to integrate them into high-density memory arrays".
