Q:what are the pros and cons of food additives?
There okorder.com/reports/chemcuisi... Hope this helped and be sure to mention that people have a right to know what is in their food. Just because someone is making big bucks selling human hair doesn't mean we should be blindly eating it because the name L-Cysteine does not say what it is.
Q:Why are food additives used in food?
I refer you also to my answer about ANTIOXIDANTS. ALL additives to food are present for a purpose: To add colour or to retain a colour; as a preservative; flavouring enhancers and emulsifying agents. There are strict laws here in England which prevent our foods from having any known dangerous additives, however although some additives are known to be harmful (like certainE" numbers which are chemically produced) others are not harmful to us, proportionally as they sourced from natural products. One can get too worried at times thinking about the lists of additives (which can be found printed upon most food lables, such as frozen products etc.) but unless you are a bio-chemist, it is hard to know what is what? A good way to know if there arwe any additives present, is by reading the main food or drink description:ORANGE FLAVOUR DRINK" for example, will probably contain NO ACTUAL ORANGES at all. The wordFLAVOUR" in the drinks title is a the give-away! Get me? The above drink would have been produced from flavourings alone and also colouring so as to taste and appear to be orange, whilst it is not! Chocolate Flavour? Coffee Flavour? Blueberry Flavour? NONE of these are natural. The flavouring of these foods will be provided by an additive and we all of us have been eating & drinking these so-called foodstuffs for many years! Hopefully without any detrimental harm to ourselves??
