The most commonly used preservatives in the manufacture of ketchup are sorbic and benzoic acid and its salts.
Sorbic acid E 200 is a potential irritant.
E 210 Benzoic acid is a weak skin irritant and eye irritant, can cause asthma, especially in subjects injecting steroid drugs asthma is considered that causes neurological disorders and interacts with sulfur bisulphite; proven provoke hyperactivity in children.
Sodium benzoate E 211 causes slight eye irritation, skin rashes, stings like a nettle and asthma.
Potassium benzoate, E 212 and E 213 calcium benzoate moat cause allergic reactions similar to benzoic acid.
Reported cases of urticaria, asthma, rhinitis and anaphylactic shock after oral, dermal or inhalation acceptance of benzoic acid and sodium benzoate.
Acute sensitivity to benzoic acid and sodium benzoate is low, but E 210, E 211, E 212 and E 213 proved to cause non-immunological contact rekatsii (psevdoalergiya). This effect is rare in healthy individuals, but common in individuals with asthma or urticaria, there is amplification of symptoms. HACSG (Hyperactive Children's Support Group) recommended to be avoided.
CONCLUSION
Lutenitsa is useful when E sterilized and no preservatives. Unsterilised Lutenitsa with preservative, can cause side effects in some consumers, even if they ARE a normative limits.
Nowadays often talk about eating healthy, clean food, and people increasingly began to watch what they eat. However, we know really what we eat? And what are the ingredients of foods we buy? And you know what it says on the label?
Some people actually eyeing the labels, read food composition, and they see something suspicious at first glance, buying food. The label, however, often has some unintelligible characters labeled as E with different numbers, such as: E 103, E 951 and a total of 1520 characters that usually no one understands and that rarely draws attention.
They assigned different types of feed additives: preservatives, antioxidants, stabilizers, emulsifiers, flavorings and improvers. It turns out that a significant proportion of these food additives are very harmful and are banned by law in many European countries, USA and Australia. Some additives cause allergies, others lead to diabetes, others irritate the stomach, a fourth bad influence on brain function, while a majority are proven carcinogens - ie, cause cancer. These additives, for which no one tells us the labels and warning us of their side activities are most dangerous for children, moreover, contained in carbonated and sweetened drinks, chewing gum, confectionery.
Every parent wants his child to eat healthy and full if you are worried about the preservatives, dyes and other additives to your child, this article will help you.
What exactly is "E" number? Each additive has a number of "E" to show that it is passed safety test and been approved for use. European legislation requires most additives used in food must be clearly indicated in the contents of food or number.
Baby food - all, all food and beverage formulas in the EU for babies under 12 months of age, fall under strict regulations governing what they can and can not contain. These regulations restrict the additives that can take your baby, while providing guidance and nutrients, including how much sugar and salt may be present in food, what minimum amount of proteins and how detailed should be labels on food products.
Infant food - bad news for food intended for children over 24 months is that laws protecting infants suddenly cease to apply. While some additives are banned in foods for children over one year old, these foods are few and rare. Children after their first one year and more can basically eat anything. When you buy takeout, it may contain large amounts of sugar, salt and lots of additives and labels are not nearly as complete as in baby food. So leave you to decide what food your child and accept what has additives in it. Studies have shown that standard preparations for children, contain an average of five additives (ingredients that you would not include if we catered to your child). First come the children's desserts, breakfast cereals, children's drinks and sandwiches. You know, means and measures to take. According to leading experts in pediatric nutrition, there are certain supplements that should seek to avoid. The best rule is if you worry about the E-th and did not recognize many of the ingredients of the food we are wondering whether to buy or content sounds dubious and incomprehensible, just not buying it.
Recommendations: If possible, avoid baking, modifitsitsirano starch, modified corn flour and starch maltodekstrinat be used for additional volume of food. Growing children need lots of nutrients rather than empty calories, so avoid foods containing baking.

Preservatives
Added preservatives in preparations designed to extend the durability of the product. Benzoate, sulfites, nitrates and nitrites are well known in that cause asthma in some children. Skin rashes and gastrointestinal problems are also associated with preservatives. Studies indicate that most preservative in baby foods contain - cakes, burgers and drinks.
E-numbers are preservatives E200 to E282. Try to avoid when buying food for your child following E's:
E210 - benzoic acid (added to the cheeses, spices, frozen foods, cosmetics and pharmaceuticals, and many others, may cause asthma, especially in steroid-dependent drugs can interact with sulfur bisulphite (222), which can lead to hyperactivity in children)
E211 - sodium benzonat (used as an antiseptic, a food preservative and taste masking, orange juices contain a high amount of up to 25mg in 250ml; also in dairy and meat products, spices, and some medicines can cause rashes and can increase asthma.)
E212 - Potassium benzonat (in children with allergic reactions. See 210)

E252 - potassium nitrate (see 249 and 250)

Colours
Food coloring is used in more for the convenience of the manufacturer than for the consumer. Usually intended to conceal components of poor quality and thus mislead the consumer about the content of the food. Azo-dyes are controversial. Most of them have E-numbers assigned to them by the EU, which means that is considered safe for use. Many of them are banned from other countries like USA, Japan and Scandinavia, because there is information that can cause asthma, skin rashes, fever, and are responsible for hyperactivity in some children. If you think additives negatively affect the health of your child, try to avoid the following:
E-numbers coloring food from E100 to E180.
