These spread in the short video of the "life tips", there is a picture of the truth, simple and effective operation, looking at people's hearts "plant grass", eager to try. But there are also netizens after trying to say that the effect is not ideal. So are all these tips reliable? Listen to what the experts have to say.
the banana root wrap tin paper will extend the shelf life? Not necessarily!
video, to keep the banana for a long time, simply clean the banana and wrap it in tin paper. It is based on the principle that the ethylene gas released by bananas accelerates the browning and maturation of bananas and the ripening of any nearby fruit. Because most of the ethylene is released from the banana root, wrapped here with tin paper or cling film, can alleviate the banana ripening process, thus achieving the purpose of prolonging the preservation time.
Wang Hao, an associate professor at Tianjin University of Science and Technology's School of Food (Tianjin Food Safety Science Base), said bananas are respiratory leap-change fruits that release large amounts of ethylene during maturity (which will ripen the bananas), at which point the fruit's breathing rate increases significantly and will quickly mature. Bananas must be removed from trees before they are fully ripe for long-distance transport to withstand long-distance transport and long-term storage.
generally speaking, consumers buy bananas of oranges and oranges, which are basically processed by artificial magency before they are sold. Wang Hao said, so the banana bought back, first with clean water to clean and dry, can reduce the surface ethylene gas attachment, is conducive to prolonging the shelf life of bananas. Wrapping banana roots with tin paper or cling film is also intended to inhibit the release of ethylene gas, which should have some effect, but the effect is not necessarily so obvious. To extend the banana shelf life, or mainly control the temperature of banana storage, generally in a dozen degrees Celsius the best, can slow down the banana breathing speed. At the same time reduce the pressure surface, it is best to hang bananas, because the tissue under pressure, will slowly soften, the pressure surface preservation is the worst.
generally, bananas that have been artificially cooked can be kept for about a week, and by technical means, the preservation period can be extended to two weeks, Said Wang Hao. If you want to store bananas for a long time, it's best to buy green bananas that haven't been artificially cooked and let them slowly cook themselves.
sleep spray is "insomniac star"? Limited effect!
year-end, is a lot of office workers rush performance of the key period, high-intensity work and pressure, so that many people feel deep anxiety, insomnia has become a common meal. At this time shake sound, small red book on the road network red recommended sleep spray has become a lot of office workers' life-saving straw. A variety of sleep sprays are said to add lavender, vanilla, chamomile essential oils and other natural sleeping ingredients, before bed on the pillow or set spray 2-3, you can let people relax, ease anxiety, thus helping to fall asleep.
To this Tianjin Stable Hospital, director of the department of mood disorders Wang Lina introduced, some plants do have the effect of god, compound vegetable essential oils cover terpenes, alcohols and esters 3 categories of ingredients, the main ingredients are acetic paracetamol, aroma alcohol and citricene. Generally speaking, alcohol sedative effect is better, relevant studies have confirmed that camphor alcohol on the central nervous system has a soothing effect, including helping sleep, anticonvulsants, hypothermia and so on. In addition, esters also have a sleep-aiding effect, can extend sleep time, these substances with the dose increase their role will be appropriately enhanced.
" this sleep spray containing essential oils as a health care products, acute insomnia patients can be used for a short period of time, but also have a certain sleep-aiding effect. There are also surveys that show that about 70% of acute insomnia patients can slowly recover through their own adjustment. But another 30 percent or so of patients will transition from acute insomnia to chronic insomnia, Wang said, and some will need to find a professional doctor for examination and a professional systematic evaluation.
chronic insomnia and sleep rhythm disorders, these health care products can not be solved. Failure to receive timely treatment from a professional doctor can lead to many emotional problems, the most common such as depression and anxiety disorders. Conversely, depression and anxiety can also lead to sleep disorders. The two interact with each other in a vicious circle.
"mouse" ultrasonic dishwasher frees hands? The measured wash is not clean...
. In winter, the most painful thing is to wash the dishes. Without hot water, greasy dishes are difficult to clean. A dishwashing artifact about the size of a mouse gives people hope of freeing their hands. In the video, the ultrasonic dishwasher is placed in the sink, and as the instrument vibrates, the oil on the dishes falls off one after another. However, video has also been sent to verify that the oil on the dishes remains through the use of ultrasonic dishwashers.
Zhang Sheng, a professor at Tianjin University's School of Chemical Engineering, explains that ultrasonic cleaning is based on the principle of using the emptying effect to clean objects, colloquially speaking, the micro-explosions and shock waves produced when the bubbles formed by ultrasonic waves break instead of hands to wash dishes, so that the dirt on the surface of the cleaned object is destroyed and quickly falls off. In general, it is better to add some extra surfactants (detergents) to the cleaning effect.
video is not ideal, mainly due to the machine's low power and the location of the dishes. Zhang Sheng said that large ultrasonic dishwashers are generally dense with ultrasonic converters at the bottom so that dishes can be cleaned from all directions. And this mouse-sized dishwasher placed in the sink, the resulting ultrasonic waves can only spread outwards, from the dishwasher near the local energy is strong, far away from the impact wave weak, will affect the cleaning effect. In addition, the amount of water in the sink is also important, when the water and power do not match, will also affect the use of ultrasonic dishwashers.
toothpaste, soda, white vinegar and other mixtures can be powerful de-fouling? It's theoretically possible . . .
. Before the Spring Festival, every household has to carry out a major clean-up, the kitchen of the old dirt can be difficult to down a lot of housewives. There are netizens timely to send the magic way to clean up, so that many people such as to get treasure. In the video, toothpaste, soda, white vinegar and finish are mixed together and wiped on the bottom of a black pot, instantly shining like a new light.
Zhang Sheng said that the main component of black scale at the bottom of the pot is a mixture of carbon, iron oxide and oil scale that gas does not burn enough. Soda is sodium bicarbonate, which helps remove oil scale. White vinegar in addition to the main component of water is acetic acid, which can help remove iron oxide. The main components of toothpaste are friction agents (calcium carbonate, calcium phosphate), and the main component of salt is sodium chloride, both of which can help remove carbon build-up. The finish is also able to remove oil scale, so this formula is based on the principle of removing dirt from the bottom of the pan.
the principle of cleaning, but in the follow-up experiments of many netizens, this formula did not play a strong role in de-fouling. Compared with the original video's "as new", the dirt on the bottom of the pot is still stubborn in the netizen experiment. In this regard, Zhang Sheng said, the formula principle is feasible, but the specific degree of cleanliness should be related to the thickness of the dirt on the bottom of the pot and the specific conditions for its formation. In addition, the netizen video added too much water, formula raw materials over-diluted, is not conducive to cleaning up dirt. In addition, iron oxide and oil scale at the bottom of the pot are relatively easy to remove, but carbon accumulation is not easy to remove. This is also one of the reasons why the formula failed.
the instant noodles repair the great law of everything? The key is to see the craft...
. Since the shaking sound, people have seen the "master in the folk". At present, the popular instant noodles repair broken furniture, toilets, floor and other videos are breathtaking. Detailed repair steps, plus instant noodles and glue - matte - polishing - painting - complete, the process is simple and rough, repaired furniture seems to the naked eye almost no trace.
for this "craft", Zhang Sheng analysis, repair mainly uses fillers and adhesives to fill holes. Traditional repair furniture will use wood powder, atomic ash, etc. to fill, and then with a specific glue fixed, and finally polished color can be. And the use of instant noodles as a filler is not not enough, but its oily, loose, large particles, if the glue is not uniform enough, repair craft is not superb enough, may affect the effect and quality of repair.
