saccharin, is the oldest sweetener. Saccharin in 1878 by the American scientists have found that soon the food industry and consumer acceptance. Saccharin sweetness of sucrose 300 to 500 times, it is not absorbed by the body metabolism of the various food production processes are stable. The disadvantage is poor taste,
shape up skechers, there is, after bitter, making it subject to certain restrictions apply.

saccharin
saccharin (Saccharin / Saccharin sodium) is a white crystalline powder, which is insoluble in water, and its sodium salt soluble in water, heat stability, the sweetness of sucrose 300 500 times, does not contain calories [1], slight bitter taste and metallic taste left in the tongue. Acute toxicity LD50 (rabbit) is 5000 ~ 8000mg/Kg BW (oral); daily intake amount of security allowed (ADI) is 0 ~ 2.5mg/Kg BW / day. Some studies showed that in animal experiments it has been found to have lead to the possibility of bladder cancer, but trials in humans found no adverse effects. Saccharin for years been the world's only mass production and use of synthetic sweeteners, especially during World War II, the use of saccharin in the world increased. Manufacture of raw materials are toluene saccharin, chlorosulfonic acid, o-toluidine, etc., are all petrochemical products. Daily life in the invention process the sugar from the regular consumption of sugar cane, sugar beet and other plants extracted. Flora There are also some sweeter than sugar substances. South America, stevia origin, sweeter than sugar from 200 to 300 times; in the West African tropical forests of bamboo yu,
skechers shape ups, the sweetness of the fruit is 3,000 times sweeter than sugar; Africa also has an anti-yam vine leaves, the sweetness of fruit 90,000 times that of sucrose. But, these thousands of times sweeter than sugar substance, we seldom see. We're usually sweeter than sugar used in the material is saccharin, which 500 times sweeter than sugar. From the chemical point of view, is simply irrelevant to the sugar and saccharin. Only one thing in common is that they have a sweet. Saccharin is how it was found? 1879 One afternoon, Johns Hopkins University laboratory, the Russian chemist Fali De Do erg, is a pleasant detour in bottles and jars in the shuttle. Today he was especially good,
shape up shoes, first, he is doing the synthesis of aromatic acid test went smoothly, and soon will have the results come out; Second, today is his birthday, his wife Natasha have a ready dinner, so he went back to gather it. Twilight on Earth, laboratory gradually dimmed. Fali De Do erg in the Gaslight flask called watching attentively. Roll of the solution, has long been the birthday dinner at night, I forgot the. Finally, experiment with looks, he was pleased to pick up the pencil on the table, log book in the experiment recorded the experimental results. At this point, the wall clock . Busy with her husband, the wife up. Her husband put on the glasses, utensils, dishes wife a dish plate. Dinner in the festive atmosphere began. Fali De Do erg crossed a steak, go into their mouths. Suddenly, he stopped chewing action, slightly surprised and asked: Strange to say, For scientists,
skechers shape up shoes, the habit, he would find out the reasons. After checking the kitchen, his eyes eye on the concerns of the utensils, he licked the plate's edge, a little look a gift horse, and then licked his hand, and then, out of pocket right away that pencil, but also tongue licking. I use it to flavor are derived from the written word pencil. To be sure,
skechers outlet, is sweet on the pencil in the lab coat. It seems, the laboratory must have a strange especially sweet substances, I'm going to check what happens. Finally, he found something called sweet from sodium o-sulfonyl imide chemical benzene. The accidental discovery to the Fali De Do Jirga opened up a path leading to new inventions. Since then, he focused all of our energy, as one to study the material extracted from coal tar. He has black, and sticky and smelly coal tar extract toluene, sulfonated by sulfuric acid, phosphorus pentachloride and ammonia treatment, and then potassium permanganate oxidation, and finally through the crystallization, dehydration and has been a especially sweet white crystals. He called it Fali De Do erg immediately announced his invention and patent in the United States. In 1886, the chemist moved to Germany, where he established the world's first saccharin from coal tar refining plant. This began saccharin into people's lives. The second argument: In 1879, when the Johns Hopkins University is laboratory work 伊拉莱姆森 and 康斯坦丁法赫 Berg home for dinner, eating is eating, they suddenly stopped down. Forgot to wash their hands before meals Faheboge, most chemists such cases, death will result, but was accidentally discovered Faheboge artificial sweeteners - saccharin. About this discovery, the two of them jointly published a paper, but only Faheboge patent saccharin's name, he had secretly applied for a patent saccharin. Later Laimu Sen said: management has been able to saccharin was widely used in the United States, so it was included in the first 675 species In 1972, the U.S. FDA under a long-term experimental results in rats fed saccharin decided to cancel the In 1977, Canada's more than one rat feeding experiments showed that a large number of saccharin may cause bladder cancer in male rats. To this end, FDA proposed a ban on use of saccharin, but the decision met with congressional opposition and passed a motion to delay the disabled.
saccharin
1991, the U.S. FDA to withdraw according to some studies the proposal to ban saccharin use. However, due to above reasons, the use of saccharin in the United States still need to label In 2000, Congress repealed the relevant laws and regulations, saccharin products do not have a health warning labels. Internationally, the use of saccharin on the rat carcinogenicity because these studies was published by a certain influence, Western countries continue to reduce the use of saccharin. But there are still people who hold different views, that saccharin is safe. My Government has also taken Yajian saccharin policies and regulations do not allow the use of baby food. Provisions of the present JECFA ADI of saccharin per kilogram of body weight per day is 0 ~ 5mg. Atlas Atlas entry for more reference materials 1
