Is all rice white?

Nearly half of the world's population lives entirely or partially on a rice diet. In some Asian countries, each person eats from 90 to 180 kilograms of rice annually. Only threshed rice is called coarse rice. In this state, the rice is still covered with a rough shell. It must be removed before rice is cooked. Rice without this coarse shell is called brown rice. It is covered with a brown husk called bran. It contains the richest supply of vitamins and mineral salts that rice grains generally have. However, brown rice does not keep as long as white rice.

Most people prefer white, well-threshed, polished rice to brown. When the rice is polished, the husks and underdeveloped grains are removed by passing them through a shelling machine and the surface of each grain is carefully worked. When threshing and processing is completed, the rice has a white and smooth surface.

In addition to ordinary polished rice, there is also rice, also processed, but slightly darker than polished. It contains more vitamin В and mineral salts. For further processing, this rice is soaked in water at a temperature slightly below boiling point, and then it is steam-dried under pressure. This process is called scalding.

Vitamins from the wetted shell penetrate the grain during this treatment. Rice originated in southern India, where it has been growing for thousands of years. From there it spread to the East, to China more than 5 thousand years ago. Prior to the XNUMXth century, rice was unknown in North America.

Where is the oldest observatory located?

In a cave in Brazil, archaeologists have discovered rock carvings of the constellations and the position of the Sun in them, which are about 10000 years old. According to scientists, the cave was used as an observatory. 4000 years ago, the Celts knew what the path of the Sun was in the sky. The stone ring of Stonehenge with amazing accuracy indicates the places of sunrise and sunset on the longest and shortest day of the year.

Machine for thinning flowers in gardens 02.05.2024

In modern agriculture, technological progress is developing aimed at increasing the efficiency of plant care processes. The innovative Florix flower thinning machine was presented in Italy, designed to optimize the harvesting stage. This tool is equipped with mobile arms, allowing it to be easily adapted to the needs of the garden. The operator can adjust the speed of the thin wires by controlling them from the tractor cab using a joystick. This approach significantly increases the efficiency of the flower thinning process, providing the possibility of individual adjustment to the specific conditions of the garden, as well as the variety and type of fruit grown in it. After testing the Florix machine for two years on various types of fruit, the results were very encouraging. Farmers such as Filiberto Montanari, who has used a Florix machine for several years, have reported a significant reduction in the time and labor required to thin flowers. ... >>

Advanced Infrared Microscope 02.05.2024

Microscopes play an important role in scientific research, allowing scientists to delve into structures and processes invisible to the eye. However, various microscopy methods have their limitations, and among them was the limitation of resolution when using the infrared range. But the latest achievements of Japanese researchers from the University of Tokyo open up new prospects for studying the microworld. Scientists from the University of Tokyo have unveiled a new microscope that will revolutionize the capabilities of infrared microscopy. This advanced instrument allows you to see the internal structures of living bacteria with amazing clarity on the nanometer scale. Typically, mid-infrared microscopes are limited by low resolution, but the latest development from Japanese researchers overcomes these limitations. According to scientists, the developed microscope allows creating images with a resolution of up to 120 nanometers, which is 30 times higher than the resolution of traditional microscopes. ... >>

Air trap for insects 01.05.2024

Agriculture is one of the key sectors of the economy, and pest control is an integral part of this process. A team of scientists from the Indian Council of Agricultural Research-Central Potato Research Institute (ICAR-CPRI), Shimla, has come up with an innovative solution to this problem - a wind-powered insect air trap. This device addresses the shortcomings of traditional pest control methods by providing real-time insect population data. The trap is powered entirely by wind energy, making it an environmentally friendly solution that requires no power. Its unique design allows monitoring of both harmful and beneficial insects, providing a complete overview of the population in any agricultural area. “By assessing target pests at the right time, we can take necessary measures to control both pests and diseases,” says Kapil ... >>

Sony Triporous Fiber sock material 27.10.2019

Sony's new high-tech fibers for textiles and garments promise extremely high levels of absorption of unwanted odors emitted through perspiration during active life.

Earlier this year, Sony began licensing proprietary porous organic material technology under the brand name Triporous. Now the company said that the first products based on this technology - threads, fabrics and clothes under the brand name Triporous FIBER - have begun to be delivered to the market.

Triporous is made from rice husks in a controlled combustion process. The result is a porous carbon structure that absorbs the entire spectrum of molecules from light to heavy. Triporous contains pores ranging in diameter from 2 nm to 50 nm and 1 µm. For example, ordinary activated carbon cannot absorb large molecules efficiently, while Triporous will absorb small and large molecules with equal efficiency.

Triporous FIBER fabrics and clothing, says Sony, effectively absorb the odors (molecules) of ammonia, acetic acid and isovaleric acid, substances normally released during human perspiration. Also, the new material has bactericidal properties, which prevents unpleasant odors from wet clothes. Most importantly, the Triporous FIBER material easily regains its absorbent properties after a normal wash in the washing machine. By the way, it would be great to see Triporous filters for vacuum cleaners and other cleaning household appliances that require periodic replacement of filter cartridges.

Finally, the production of Triporous FIBER is completely ecological and makes it possible to utilize organic plant residues. Up to 2 million tons of rice husks are utilized annually in Japan alone, and up to 100 million tons worldwide. This knowledge will help to warm the soul, just as the Triporous FIBER material will warm the body.
