The study aims to describe the main classes of antioxidants existing in fruit, beverages, vegetables and herbs and the different extraction and application of antioxidants in food. Oxidative degradation of lipids, especially induced by reactive oxygen species, leads to quality deterioration of foods and cosmetics and could have harmful effects on health. A major challenge is to develop tools to assess the antioxidant capacity and real efficacy of these molecules.

Part 1 Oxidation in animal products: Oxidation and protection of red meat; Oxidation and protection of poultry and eggs; Oxidation and protection of fish; Oxidation and protection of milk and dairy products; Oxidation of fish oils and foods enriched with omega-3 polyunsaturated fatty acids. Part 2 Oxidation in plant-based foods and beverages: Oxidation of edible oils; Preventing oxidation during frying of foods; Oxidation and protection of nuts and nut oils; Lipid oxidation in emulsified food products; Oxidation of confectionery products and biscuits; Oxidation of cereals and snack products; Oxidative stability of antioxidants in fruit and vegetables; Flavour changes in beer: Oxidation and other pathways; Wine Oxidation. Part 3 Antioxidant delivery in foods and beverages: Use of encapsulation to inhibit oxidation of lipid ingredients in foods; Antioxidant active food packaging and antioxidant edible films.

Generation of reactive oxygen species ROS is associated with dysregulation of antioxidant defense mechanisms and incidence of human diseases. The specific aim of this study was to investigate the lipid oxidation and antioxidant activity of aqueous extract of Rheum officinale Baillon rhizome in order to evaluate its potential as a future novel natural antioxidant resource and a functional ingredient in food and pharmaceutical formations. Total phenolic and flavonoid contents of Rheum rhizome extract were dose dependently increased. In addition, the treatment of aqueous Rheum rhizome extract significantly increased ferric reducing and copper chelating activities. According to results of thiobarbituric acid reactive substance analysis, Rheum rhizome extract significantly delayed lipid oxidation. Moreover, superoxide anion production was significantly lower in Rheum rhizome extract-treated RAW These findings suggest that Rheum officinale Baillon rhizome extract has a potential as an excellent natural antioxidant agent.

Oxidation in Foods and Beverages and Antioxidant Applications

In recent years, there has been a great deal of attention toward the field of free radical chemistry. Free radicals reactive oxygen species and reactive nitrogen species are generated by our body by various endogenous systems, exposure to different physiochemical conditions or pathological states. A balance between free radicals and antioxidants is necessary for proper physiological function. If free radicals overwhelm the body's ability to regulate them, a condition known as oxidative stress ensues. Free radicals thus adversely alter lipids, proteins, and DNA and trigger a number of human diseases. Hence application of external source of antioxidants can assist in coping this oxidative stress.

Natural antioxidants: sources, extraction and application in food systems

Part 1 Oxidation in foods and beverages: Understanding oxidation processes in foods; Metals and food oxidation; The impact of singlet oxygen on lipid oxidation in foods; Heme proteins and oxidation in fresh and processed meats; Lipoxygenase and lipid oxidation in foods; Understanding and reducing oxidative flavour deterioration in foods; Health aspects of oxidized dietary fats; Methods to determine the extent of lipid oxidation in foods; Methods for food shelf life determination and prediction. Part 2 Antioxidants in foods and beverages: Understanding antioxidant mechanisms in preventing oxidation in foods; Protein antioxidants for the stabilisation of lipid foods: Current and potential applications; Synthetic and natural antioxidant additives in food stabilisation: Current applications and future research; Effects of food structure and ingredient interactions on antioxidant capacity; Assessing the activity of natural food antioxidants; Effects of processing and storage on antioxidant efficacy in foods. Oxidative rancidity is a major cause of food quality deterioration, leading to the formation of undesirable off-flavours as well as unhealthful compounds. Antioxidants are widely employed to inhibit oxidation, and with current consumer concerns about synthetic additives and natural antioxidants are of much interest. The two volumes of Oxidation in foods and beverages and antioxidant applications review food quality deterioration due to oxidation and methods for its control.

 - Нам нужны точные цифры. - Звездочка, - повторила Сьюзан, - это сноска. Соши прокрутила текст до конца раздела и побелела. - О… Боже ты. - В чем дело? - спросил Джабба.

Я из канадского консульства. Я пришел, чтобы убедиться, что с вами все в порядке. Внезапно в гимнастическом зале, превращенном в больничную палату, повисла тишина. Старик внимательно разглядывал подозрительного посетителя. Беккер перешел чуть ли не на шепот: - Я здесь, чтобы узнать, не нужно ли вам чего-нибудь.

Перелом запястья, разбитая голова - скорее всего ему оказали помощь и давно выписали. Беккер все же надеялся, что в клинике осталась какая-то регистрационная запись - название гостиницы, где остановился пациент, номер телефона, по которому его можно найти. Если повезет, он разыщет канадца, получит кольцо и тут же вернется домой. Если потребуется, заплатите за это кольцо хоть десять тысяч долларов. Я верну вам деньги, - сказал ему Стратмор.

Сьюзан на экране тянулась к нему, плача и смеясь, захлестнутая волной эмоций. Вот она вытерла слезы. - Дэвид… я подумала… Оперативный агент Смит усадил Беккера на сиденье перед монитором. - Он немного сонный, мадам. Дайте ему минутку прийти в .

Притормозив, он задумался, в какую сторону повернуть, и в этот момент мотор его веспы кашлянул и заглох. Стрелка топливного индикатора указывала на ноль. И, как бы повинуясь неведомому сигналу, между стенами слева от него мелькнула тень. Нет сомнений, что человеческий мозг все же совершеннее самого быстродействующего компьютера в мире.

Я был уверен, что он тебе все рассказал. Сьюзан ощутила угрызения совести.

Беккер легонько обнял. Девушка высвободилась из его рук, и тут он снова увидел ее локоть. Она проследила за его взглядом, прикованным к синеватой сыпи.

Уничтожение банка данных АНБ - акт агрессии, на которую, была уверена Сьюзан, Танкадо никогда бы не пошел. Вой сирены вернул ее к действительности. Она смотрела на обмякшее тело коммандера и знала, о чем он думает. Рухнул не только его план пристроить черный ход к Цифровой крепости. В результате его легкомыслия АНБ оказалось на пороге крупнейшего в истории краха, краха в сфере национальной безопасности Соединенных Штатов.
