Food additives are substances added to food to preserve flavor or enhance taste, appearance, or other sensory qualities. Some additives have been used for centuries as part of an effort to preserve food, for example vinegar pickling , salt, salting , smoke smoking , sugar crystallization , etc. This allows for longer-lasting foods such as bacon , sweets or wines.

They do that by donating their own electrons to free radicals without becoming free radicals in the process themselves, hence terminating the radical chain reaction. Save to Library. Create Alert.

Food additive

Food additive , any of various chemical substances added to foods to produce specific desirable effects. Additives such as salt , spices , and sulfites have been used since ancient times to preserve foods and make them more palatable. With the increased processing of foods in the 20th century, there came a need for both the greater use of and new types of food additives. Many modern products, such as low-calorie, snack, and ready-to-eat convenience foods, would not be possible without food additives. There are four general categories of food additives: nutritional additives, processing agents, preservatives, and sensory agents. These are not strict classifications, as many additives fall into more than one category.

These compounds can be natural or synthetic. Preservatives play important roles in many products people use every day — for example, by helping prevent the growth of harmful microorganisms and protect products from spoilage or contamination. Preservatives are added to food to fight spoilage caused by bacteria, molds, fungus, and yeast. Preservatives can keep food fresher for longer periods of time, extending its shelf life.

All food additives used in Australia undergo a safety assessment, which includes rigorous testing, before they are approved. Toxicological tests on animals are used to determine the amount of the additive that is expected to be safe when consumed by humans. If there is any doubt over the safety of an additive, approval is not given. If new scientific information becomes available suggesting that a food additive is no longer safe, the approval to use the food additive would be withdrawn. Most food additives are tested in isolation, rather than in combination with other additives.

Food preservation has been around for centuries. It began in ancient times with the use of salt on meats and fish. Later, sugar was used in canned foods and humans began pickling vegetables.

 Сьюзан, это же абсолютно ясно. Танкадо выгравировал ключ Цифровой крепости на кольце. Золото долговечно. Что бы он ни делал - спал, стоял под душем, ел, - ключ всегда при нем, в любую минуту готовый для опубликования. - На пальце? - усомнилась Сьюзан.  - У всех на виду.

Деление на ноль. Бринкерхофф высоко поднял брови. - Выходит, все в порядке. - Это лишь означает, - сказала она, пожимая плечами, - что сегодня мы не взломали ни одного шифра. ТРАНСТЕКСТ устроил себе перерыв.

Однажды вечером на университетском представлении Щелкунчика Сьюзан предложила Дэвиду вскрыть шифр, который можно было отнести к числу базовых. Весь антракт он просидел с ручкой в руке, ломая голову над посланием из одиннадцати букв: HL FKZC VD LDS В конце концов, когда уже гасли огни перед началом второго акта, его осенило. Шифруя послание, Сьюзан просто заменила в нем каждую букву на предшествующую ей алфавите. Для расшифровки Беккеру нужно было всего лишь подставить вместо имеющихся букв те, что следовали непосредственно за ними: А превращалось в В, В - в С и так далее. Беккер быстро проделал это со всеми буквами. Он никогда не думал, что четыре слова могут сделать его таким счастливым: IM GLAD WE MET Что означало: Я рада, что мы встретились.

 Я ведь тебе уже говорил! - взмолился Хейл, не обращая внимания на вой сирены.  - Я шпионил за Стратмором. Эти письма в моем компьютере скопированы с терминала Стратмора - это сообщения, которые КОМИНТ выкрал у Танкадо. - Чепуха. Ты никогда не смог бы проникнуть в почту коммандера.

Поскольку Цифровая крепость - это японский код, никто никогда не заподозрит, что наше агентство имеет к нему отношение. Единственное, что нам нужно, - осуществить такую подмену. Сьюзан сочла его план безукоризненным. Вот он - истинный Стратмор. Он задумал способствовать распространению алгоритма, который АНБ с легкостью взломает. - Полный и всеобщий доступ, - объяснял Стратмор.  - Цифровая крепость сразу же станет всеобщим стандартом шифрования.
