Kelp and MSG
Kelp is both a good dish and a good medicine. It has a good effect on goiter (ie, big neck disease). MSG is a condiment used by people when cooking. One comes from the seaside and the other comes from a factory. The two seem a bit unrelated, so why are they related to each other? Strangely enough, there is an inseparable history of kinship between them!
About one day ago, a chemistry professor named Ikeda Kikunae from Imperial University of Japan was startled when he was eating vegetables and soup at home. He quickly asked his wife: "Why is this bowl of soup like this today?" Delicious?" Then he stirred it in the bowl a few times with a spoon, and found that in addition to a few slices of cucumber, there was also a little kelp. With the agility and interest typical of a scientist, he conducted a detailed chemical analysis of kelp. After half a year of research, he discovered that kelp contained a substance - sodium glutamate, and gave it an elegant name - monosodium glutamate. Later, he further invented a method to extract sodium glutamate using wheat and defatted soybeans as raw materials, which opened up broad prospects for the factory production of MSG.
Fishing out the food freezing method
If you pay attention to the opportunities around you and explore them with persistence, you will develop new wealth.
In 1940, the American leather merchant Bacha received $10,000 after selling his patent on the food freezing method. This wealth was acquired entirely due to his hobby of fishing.
Bacha often went to the coast of Newfoundland and dug holes in the ice to fish. The fish caught from the sea will freeze hard immediately when placed on the ice. When the frozen fish was eaten a few days later, Bacha found that as long as the ice on the fish did not melt, the fish taste remained unchanged. Based on this discovery, Bacha began experimenting with freezing meat and vegetables. He was delighted to discover that meat and vegetables could stay fresh as long as they were frozen like the fish. After repeated experiments, he further discovered that different freezing speeds and methods will affect the taste and freshness of frozen food. After months of tireless exploration, Bacha applied for a patent for the food freezing method he invented. Since this is a new technology with great potential and application scope, many people come to our door. Bacha waited for a price, and in the end, General Foods acquired the patent for a huge sum of 10,000 US dollars.
The advent of the magnetic therapy watch strap
In Nakano District, Tokyo, Japan, there lived a poor intellectual - Tanaka Shoichi. He had no career and no money, but he stayed in bed all day long. He developed a "ferrite magnet" at home behind closed doors and was regarded as a "weirdo" by his neighbors. At that time, he suffered from "neuralgia", which could not be cured no matter how hard he treated it. At that time, every Thursday he would take many prepared magnets to the Ojingdu Industrial Laboratory for testing. As time passed, an accidental phenomenon occurred: his neuralgia was relieved every Thursday. Tanaka Shoichi was a very inquiring person. He was very curious, so he found a piece of adhesive plaster, evenly stuck five small magnets on it, and stuck it on his wrist for experiment. Soon, he discovered that this device was very effective in treating neuralgia, and immediately applied for a patent. Masaichi Tanaka believes: "Arrange the south pole and north pole of the magnet staggered with each other, so that the magnetic lines of force act on the human body. Since there are crisscross blood vessels in the human body, when the blood flows through the magnetic field, a microcurrent can be induced. This current can achieve therapeutic effects. "It has the effect of strengthening the body." After obtaining the patent, Tanaka Shoichi imitated the style of the watch strap, manufactured a magnetic therapy belt with six small magnets around it, and launched it on the market. After the product was launched, it turned out to be extraordinary. People all over Japan were rushing to buy it. The factory's three-shift production also exceeds supply. During the peak sales period, sales reached 200 million yen in just one week. Just like that, in the blink of an eye, a poor man became a rich man!
