Відповідь до p. 46 ex. 3:
Food additives are substances to food to preserve flavor or enhance its taste and appearance. Some additives use for centuries; for example, preserving food by pickling (with vinegar), salting, as with bacon, preserving sweets or using sulfur dioxide as in some wines. With the advent of processed foods in the second half of the 20th century, many more additives were introduced, of both natural and artificial origin. To regulate these additives, and inform consumers, each additive are assigned a unique number, termed as "E numbers", which is used in Europe for all approved additives. E numbers are all prefixed by "E", but countries outside Europe use only the number, whether the additive is approved in Europe or not. For example, acetic acid is written as E260 on products sold in Europe, but is simply known as additive 260 in some countries. Additive 103, alkanet, is not approved for use in Europe so does not have an E number, although it is approved for use in Australia and New Zealand. Since 1987, Australia has an approved system of labeling for additives in packaged foods. Each food additive has to be named or numbered. Each number is the same as in Europe, but without the prefix "E". The United States Food and Drug Administration lists these items as "Generally recognized as safe" or GRAS; now they are listed under both their Chemical Abstract Services number and Fukda regulation under the US Code of Federal Regulations.
