Thaumatin E , a naturally sweet protein extracted from the fruit of the plant Thaumatococcus danielli, is times sweeter than sugar and is used at very low levels for its flavouring properties. Bulk sweeteners include sorbitol E , isomalt E and maltitol E and these can be incorporated into "table-top" sweeteners and in energy-reduced foods, in which they provide volume and mouth feel.

Whilst adding colour may appear to some to be purely cosmetic, there is no doubt that colour is important in consumer perception of a food and it is often associated with a specific flavour and intensity of flavour. Colours are used to add or restore colour in a food in order to enhance its visual appeal and to match consumer expectations. The processing of peas and the preparation of jams can lead to loss of colour, and hence food colours can compensate for these losses.
Some colours are used purely for visual decoration on cakes and confectionery items. Masking or disguising inferior quality, however, are unacceptable uses of colours. To offset colour loss due to exposure to light, air, extremes of temperature, moisture and storage conditions. To compensate for natural or seasonal variations in food raw materials or the effects of processing and storage to meet consumer expectations Masking or disguising inferior quality, however, are unacceptable uses of colours. To enhance colours that occur naturally but at levels weaker than those usually associated with a given food.
The Acceptable Daily Intake ADI is defined as an estimate of the amount of a food additive, expressed on a bodyweight basis that can be ingested on a daily basis over a lifetime without appreciable risk to health. The ADI is usually given as a range of 0-x milligrams per kilogram of bodyweight per day. ADIs serve to protect the health of consumers and to make international trade in food easier. The ADI is a practical approach to determining the safety of food additives and is a means of achieving some harmonisation of regulatory control. The advantage of regulatory and advisory bodies setting ADIs for food additives is that they are universally applicable in different countries and to all sectors of the population.
Basically, expert scientific committees advise national and international regulatory authorities. The safety assessments of food additives have developed along similar lines in individual Member States in the European Union and in the wider international community. A standard called the General Standard for Food Additives GSFA has been established by Codex, with the aim of developing a harmonised, workable and indisputable international standard for world trade.
Only those additives that have been evaluated by the JECFA and found to meet the necessary standards of use in foods are included. The safety evaluation is based on a scientific review of all pertinent toxicological data on the specific additive-both observations in humans and mandatory tests in animals.
The toxicological tests required by the regulatory authorities include lifetime feeding studies and multigenerational studies that determine how the additive is handled by the body in order to assess any possible harmful effects of the additive or its derivatives. The NOAEL is then divided by a safety factor, usually , which results in a large margin of safety. It is therefore prudent to adjust for possible differences by assuming that man is more sensitive than the most sensitive test animal.
Secondly, the reliability of toxicity tests is limited by the number of animals tested. Such tests cannot represent the diversity of the human population, subgroups of which may show different sensitivities e. Again, it is prudent to adjust for these differences. Traditionally, the World Health Organisation has used a safety or uncertainty factor of , based on a fold factor to allow for differences between animals and an average human, and a fold factor to allow for differences between average humans and sensitive subgroups pregnant women, the elderly.
However, this may be varied according to the characteristics of the additive, the extent of the toxicology data and the conditions of use. The consumption of an additive above its ADI on a given day is not a cause for concern because the ADI has a large built-in safety factor and in practice, consumption above the ADI on one day is more than accounted for by consumption below the ADI on most other days. However, if an intake figure indicates that the ADI may be regularly exceeded by certain sectors of the population, it may be necessary for the European Food Safety Authority to advise a reduction of levels in foods consistent with the amount needed to achieve its function, or to reduce the range of foods in which the additive is permitted for use.
Because of the large safety margin used in setting the ADI, it is likely that an ADI for a given additive would have to be exceeded by some considerable amount for there to be any risk of harm to human health. The monitoring of food additives is carried out by individual Member States on advice from the European Food Safety Authority. The ADI is compared with "average" and "extreme" consumption estimates in the population as whole or in particular subgroups of the population.

Provided that intakes for average and extreme consumers are within the ADI, it is unlikely that any harm will result because the ADI is based on a no-observed adverse effect level, to which a large safety margin has been applied. To ensure that consumers are not exceeding the ADI by consuming too much or too many products containing a particular additive, EU legislation requires that intake studies be carried out to assess any changes in intake patterns.

Nowadays even a child knows that human-made foodstuffs have special ingredients — food additives.
They are flavors, emulsifiers, food colorings, preservatives and other substances which enhance the flavor and add required qualities to products. More and more often we hear about components which are made of genetically modified organisms. To classify food additives within EU countries a special numbering system was invented. It has been working since A healthy diet is the basis for our well-being that is why it is very important to have detailed information about components of the aliments.
Some food additives, which are considered to be harmless or whose negative impact has not been proved, actually are very dangerous. Some of them can fall into toxic components under certain circumstances at a temperature of a human body or because of gastric juices. Harm of some synthetic additives appears because of chemical reactions with other foodstuffs. According to statistics, a person on average eats 5 kg of food additives every year.
Most of such ingredients we use in our diet without any worries: sugar, vanilla, salt, gelatin, bicarbonate of soda, vinegar, B-Carotene, ascorbic acid, pectin, egg white and other food additives. Any way, it is important to remember that only you are responsible for your life. So while shopping you need to follow certain rules. When you buy aliments, you must examine labels and keep in mind that the list of ingredients in unhealthy food is longer as far as it contains more food additives.
