Buy and dye the steamed bun Should take care additive is excessive

Buy and dye the steamed bun Should take care additive is excessive
China disease accuse of centre poison MaoBai Ding, researcher of control centre, afraid of fake and poor the intersection of mountain and the intersection of pear and sour potassium use mountain pear sour potassium getting white the intersection of scale and flaky crystallization or crystallization nature powder most, without bad smell or have pungent smell slightly. The scientific name is own two alkene sour potassium, it is universally acknowledged security type food additive and food antioxidant, belong to the food preservative of organic all kinds of acid, apply to trades such as food, beverage, tobacco, pesticide, cosmetics,etc. extensively. As the unsaturated acid, can also be used in the resin, spices and rubber industry. Mountain pear sour potassium can inhibit the activity of oxygen bacterium of becoming reconciled of mould, yeast effectively, still can prevent growth and reproduction of harmful microorganisms such as the poisonous bacillus of meat, staphylococcus, salmonella,etc., lengthen the holding time of the food, and keep the flavor of the original food. Its antiseptic result is far higher than sodium benzoic acid. Sour potassium toxicity of the mountain pear is extremely low, half the number oral fatal dose of big mouse is 4340mg/kg. Feed the big mouse for 13 weeks continuously with extremely heavy dose of 683mg/kg, only find the great mouse's appetite drops, dissecting and showing the kidney has slight swelling. Become fibrous 48 hour such as cell with the intersection of ladder and the intersection of density and hamster trained to impregnate, high density in 4mg/L, just observe that there is cell toxicity. So, it is given a recommendation as high-efficient and safe antiseptic antistaling agent, allow intaking amount to be 25mg/kg every day when WHO stipulates. But the present subject problem is that sour potassium of fake and poor mountain pear floods the market: Some mix potassium carbonic acid in mountain pear sour potassium products, or add industrial chemicals brightening agent, in order to increase the white degree of the products and conceal the yellow become badly, produced, some passes potassium benzoic acid off as mountain pear sour potassium. It is amino sodium sulfonic acid of own base of ring that the happiness usually cooks the steamed bun and very happy plain scientific name all without exception, it is edulcorant of a kind of artificial synthesis, its sugariness is 30~40 times that of cane sugar, but the cost is only 2~3 times of the cane sugar. It is commonly used additive in food production such as cold drink, fruit juice, ice cream, cake food and candied fruit now. The happy and plain experimental data reveal their acute toxicity is very low, the little mouse is 16000mg/kg through half the number fatal dose of the mouth. The toxic experiment of heredity reveals, cause the density level that DNA damages to be 2mg/kg. It is plain that these basic data prove that happy it is very safe. But the finding in 1966 is happy and plain could resolve under the fungus function of intestines into having chronic and toxic own amine of ring. It is reported even more in 1969, 10: Happy plain saccharin mixture of 1 can be caused bladder cancer take place in the big mouse. But there are more experiment reports besides and claim not to find to be happy to be carcinogenic. Including China, allow to use the happy and plain country to exceed 55 at present, its daily maximum consumption is 650~800mg/kg. According to the regulation of scope of application of additive, happy to can be use for food such as the biscuit, cake, bread while being plain. Unless so it although steamed bun refer to directly, contrast by bread,use it and all without exception but. It is a kind of artificial synthesis pigment that it is not used lemon yellow at will that lemon yellow, it is orange powder, scientific name 3- carboxyl -5- hydroxy ( To sulphur benzene) -4 - (phenyl even nitrogen to sulphur) Nitrogen luxuriant three sodium in the neighbor. It does not basically have poisonous substance quality, the main raw materials for production, to amino benzene sulfonic acid and wine stone and sour material that is basically nonpoisonous that lemon yellow to belong to. Behind entering the human body, the majority is discharged outside the body with the true features, does not accumulate in the body, small quantity can be discharged by the urine after metabolizing. Half the number lemon yellow fatal dose of injection reaches 1000mg/kg in the big mouse's abdominal cavity, reproduction toxicity is studied and shown, big mouse female feed dosage reach 1280mg/kg, will it be 7~14 day pregnancy period, nurse and wean issue and contrast, have no difference to the intersection of son and mouse. The above-mentioned experimental data show, it is the safe material to be lemon yellow, so has the edible pigment that various countries employed extensively all the time. What WHO gives allows the intaking amount to be extremely extensive every day, reach as high as 0.75mg/kg, or an adult of weight of about 60 kilograms, every daily intaking amount will not produce danger either while reaching 40mg. Though lemon yellow to it uses as food additive to be quite safe, it adds to be not in accordance with regulation at will as the intersection of Shanghai and the intersection of steamed bun and that kind, belong to and exceed standard to use, this is the subject problem existing.
