Lead you to know food additive

Lead you to know food additive
Since food additive is closely linked with our life, will print various batching on the packaging of nearly all food: The batching is praised by the food processing producer, then, what kind of magic power food additive has on earth, can let the trade company regard as the gods, let the food liked at will by consumers, is it habit-forming to eat? Are people really due to additive? Let us probe into the secret among them with expert.

Food additive is something
Refer to food additive, what people associated it with often hangs white piece, the Sudan red and gathering cyanogen amine three times, many people even these once " poisonous substance " Draw the equal sign with food additive. But in fact, food additive question is much more complicated.
According to the definition of " food hygiene law of the People's Republic of China ", food additive means " in order to improve food quality and colour, fragrance and taste, and add the synthetic or natural material of chemistry in the food for need of the antiseptic and preparation method. "
Chen HePing puts a thick " food additive manual " in front of the reporter, introduce patiently, " the function of food additive is enormous, can't deny without exception. " For example salt, this may be the oldest food additive, when the mankind is still in the primitive society, people know that must eat the salt. Modern science proves, the salt supplements physical power, promotes the function digested, the adult needs 3-5 grams of salt at least every day. Mention in the preceding paragraphs hang white piece and the Sudan red and gathering cyanogen amine 3 times, these materials can only originally be applied to the industrial field, it is not food additive. So, food additive can't be with " poisonous substance " briefly Draw first-class number.
China is implementing the strict examination and approval system to food additive like most countries. The additive has strict restriction in using, forbid using excessively. Food and Agriculture Organization of the United Nations and World Health Organization affiliated food additive Committee of Experts have stipulated one " ADI " The value, namely according to the human weight, take in a kind of estimated value not allowing the intaking amount every day when health endanger food additive. For example: ADI value of saccharin sodium is 5 milligrams kilogram, namely the saccharin sodium allows the intaking amount as 5 milligrams for per kilogram of weight every day, that is to say, a person 50 kilograms in weight, the permission value most greatly taking in saccharin sodium in one day is 250 milligrams. In addition, the happy and plain ADI value is 11 milligrams kilogram, ADI value that Ann is comparable to the honey is 15 milligrams kilogram, ADI value with plain sweet taste is 40 milligrams kilogram, (sodium) benzoic acid ADI in value for 5 milligrams kilogram,mountain ADI of potassiums sour is for 25 milligrams kilogram in value pear.
Certainly these are stipulating the intaking amount of adults, children's intaking amount should be smaller as to adult. Moreover, this is only the limit of only what the human body confirms too, reach a certain food of a certain producer specifically, it is unqualified, in other words, how much the producer would like to add, how much can be added, because this standard is people's individual intaking amount, but not food addition level.
Why additive can be favored by the food processor
Food additive of our country has 2000 multi-type at present, have 22 kinds in all. Including (1) Preservative (2) Antioxidant (3) Send color pharmaceutical (4) Bleaching agent (5) Acidic flavoring agent (6) Solidify pharmaceutical (7) Loosen pharmaceutical (8) Thickening agent (9) Subdue pharmaceutical (10) of bubble Edulcorant (11) Colorant agent (12) Emulsifier (13) Modifier (14) of quality Resist and form pharmaceutical (15) Increase flavor pharmaceutical (16) A enzymic preparation (17) Capsule pharmaceutical (18) Foam pharmaceutical (19) Antistaling agent (20) Spices (21) Nutrition fortifier (22) Other additive.
In food production, the trade company is in order to improve food quality, will add pigment, spices, bleaching agent, increase bad smell pharmaceutical, edulcorant, loosen pharmaceuticals; In order to prevent the food from being putrid and deteriorated, will add antioxidant and preservative; To facilitate processing, will add emulsifier, subdue bubble pharmaceutical; In order to increase the nutritive value of food, will add nutrition fortifiers such as vitamin, amino acid, mineral,etc..
Nowadays, food additive permeates through each corner where we live, when tasting the cake, will only pay attention to the soft and fine and smooth mouthfeel such as us, sweet milk perfume, but we are not clear why the cake can have these characteristics. Ms Zhang work for many years in one the intersection of cake and room of mega-store, she chase the intersection of number and additive in the cake: "Soft, it is the contribution that bubbles hit the powder; Fine and smooth, rely on the oil of cake to accomplish; The milk is fragrant, it is the taste of the cream; Want sweet taste and fruit to be fragrant, add edulcorant and essence. In a word, without food additive, we can not make into so delicious a cake at all. " She remembered she in just experience of entry at the beginning of the eighties of last century, " there was not oil this kind of additive at that time, egg liquid send course to be very much slow, can reach the result perhaps either for half an hour. Not only the producing rate is low, the finished mouthfeel is also very coarse, also there is serious egg offensive smell sometimes. " Since adding the oil of cake, only have about 10 minutes to drop to to kill time, and the mouthfeel becomes much better.How can the producer bore the gap of the regulation
Even if food additive is that the food processing has brought so many facilities, Chen HePing still expresses the current situation of food additive that worried: "It is in food additive totally is nonpoisonous harmless,it wants that it is be careful to hold with, principle that use been littled, avoid that because abuses food additive and endangers the health. " Among them, edible pigment and preservative are that food additive field endanger two greatest big classes, need to control the consumption strictly. He explains, no matter the Sudan regarded as the industrial dyestuffs is red, or red as the three-coloured amaranth of the edible pigment, all even nitrogen compound in essence, because extraction crafts are different, produced the difference on molecular structure, if a large amount of long-term edible three-coloured amaranth are red,etc., will still have carcinogenic possibility.
Because the relevant regulation is not yet complete enough at present, " abide by the law " The food which the trade company produced, may not necessarily let people rest assured to eat either. "We use candied fruit as the example, besides using the sugar, the producer certainly also needs other methods to improve the sugariness, edulcorant becomes the choice of the producer. " Because the relevant regulation has regulation that limit used to various edulcorants, the producer puts all several kinds of edulcorants into food. "Saccharin sodium put some, happy to usually put a little more, two kinds of edulcorants are entered, their own consumption is slightly lower than what the regulation is limited. In this case, the trade company still strictlies observe the laws and regulations, ultra quantity does not use food additive, can food can increase to hidden danger that health cause at double in fact. " In the field of colorant agent, such a question may be more outstanding - -If it is single to use a certain colorant agent, reach, colour, require, the producer will add together using with different types of colorant agents, endanger and well imagine.
