Drinking coffee has become part of our everyday culture. Coffee cultivation is devoted to over 50 countries in the world, located between latitudes 25 degrees North and 30 degrees South. Green raw coffee can not be used to prepare coffee beverages, coffee beans must first be roasted. Roasting coffee and reaching a certain degree of coffee roasting determine its flavor and aroma characteristics.

Coffee: biochemistry and potential impact on health.

This review provides details on the phytochemicals in green coffee beans and the changes that occur during roasting. Key compounds in the coffee beverage, produced from the ground, roasted beans, are volatile constituents responsible for the unique aroma, the alkaloids caffeine and trigonelline, chlorogenic acids, the diterpenes cafestol and kahweol, and melanoidins, which are Maillard reaction products.

The fate of these compounds in the body following consumption of coffee is discussed along with evidence of the mechanisms by which they may impact on health. Finally, epidemiological findings linking coffee consumption to potential health benefits including prevention of several chronic and degenerative diseases, such as cancer, cardiovascular disorders, diabetes, and Parkinson's disease, are evaluated.

Cafestol is a diterpenoid molecule present in coffee beans. It is one of the compounds that may be responsible for proposed biological and pharmacological effects of coffee. A typical bean of Coffea arabica contains about 0. In filtered coffee drinks such as drip brewed coffee, it is present in only negligible amounts, as the paper filter in drip filtered coffee retains the diterpenes. Coffee consumption has been associated with a number of effects on health and cafestol has been proposed to produce these through a number of biological actions.


Finally, epidemiological findings linking coffee consumption to potential health benefits including prevention of several chronic and degenerative diseases, such as cancer, cardiovascular disorders, diabetes, and Parkinson's disease, are evaluated.

Phenolic compounds in coffee 1. Phenolic compounds are secondary metabolites generally involved in plant adaptation to environmental stress conditions. These compounds have a number of beneficial health properties related to their potent antioxidant activity as well as hepatoprotective, hypoglycemic and antiviral activities. The main groups of CGA found in green coffee beans include caffeoylquinic acids, dicaffeoylquinic acids, feruloylquinic acids, p -coumaroylquinic acids and mixed diesters of caffeic and ferulic acids with quinic acid, each group with at least three isomers. During coffee processing, CGA may be isomerized, hydrolyzed or degraded into low molecular weight compounds.

This review provides details on the phytochemicals in green coffee beans and the changes that occur during roasting. Key compounds in the coffee beverage, produced from the ground, roasted beans, are volatile constituents responsible for the unique aroma, the alkaloids caffeine and trigonelline, chlorogenic acids, the diterpenes cafestol and kahweol, and melanoidins, which are Maillard reaction products. The fate of these compounds in the body following consumption of coffee is discussed along with evidence of the mechanisms by which they may impact on health.

 Вижу, - сказал Бринкерхофф, стараясь сосредоточиться на документе. - Это данные о сегодняшней производительности. Взгляни на число дешифровок. Бринкерхофф послушно следил за движениями ее пальца. КОЛИЧЕСТВО ДЕШИФРОВОК О Мидж постучала пальцем по этой цифре. - Я так и думала. Деление на ноль.

Все сказанное было вполне в духе Грега Хейла. Но это невозможно. Если бы Хейлу был известен план Стратмора выпустить модифицированную версию Цифровой крепости, он дождался бы, когда ею начнет пользоваться весь мир, и только тогда взорвал бы свою бомбу, пока все доказательства были бы в его руках. Сьюзан представила себе газетный заголовок: КРИПТОГРАФ ГРЕГ ХЕЙЛ РАСКРЫВАЕТ СЕКРЕТНЫЙ ПЛАН ПРАВИТЕЛЬСТВА ВЗЯТЬ ПОД КОНТРОЛЬ ГЛОБАЛЬНУЮ ИНФОРМАЦИЮ. Что же, это очередной Попрыгунчик.

 Я люблю тебя, - шептал коммандер.  - Я любил тебя. У нее свело желудок.

 - Я и понятия не имел.  - Его глаза сузились.  - Так к чему ты клонишь.

Но того человека в очках нигде не. Были другие люди. Празднично одетые испанцы выходили из дверей и ворот на улицу, оживленно разговаривая и смеясь. Халохот, спустившись вниз по улочке, смачно выругался. Сначала от Беккера его отделяла лишь одна супружеская пара, и он надеялся, что они куда-нибудь свернут.

Вскоре спуск закончился, переключились какие-то шестеренки, и лифт снова начал движение, на этот раз горизонтальное.

А потом этот парень умер. - А вы пробовали сделать ему искусственное дыхание? - предположил Беккер. - Нет.

В голосе ее прозвучала удивительная решимость: - Мы должны установить с ним контакт. Должен быть способ убедить его не выпускать ключ из рук. Мы обязаны утроить самое высокое сделанное ему предложение.
