UHT treatment requires both a sterilizer and an aseptic unit for packaging the product. It is used for low acid above pH 4. The same process is also used to sterilize prepared food, such as soups, sauces, desserts, tomato and fruit preparations, and baby food. The birth of high heat treatment and canning as a means of preserving food began in France in the early s. By , tin-coated steel containers were widely in use.

Sterilization of milk is aimed at killing all microorganisms present, including bacterial spores, so that the packaged product can be stored for a long period at ambient temperature, without spoilage by microorganisms. Since molds and yeasts are readily killed, we are only concerned about bacteria. The latter two are examples of so-called UHT ultra-high-temperature, short time treatment. It does not inactivate all enzymes, e. The undesirable secondary effects of in-bottle sterilization like browning, sterilization flavor, and losses of vitamins can be diminished by UHT sterilization. During packaging of UHT-sterilized milk, contamination by bacteria has to be rigorously prevented. After UHT sterilization, certain enzymatic reactions and physicochemical changes still may occur.

The process is intended to destroy or deactivate organisms and enzymes that contribute to spoilage or risk of disease, including vegetative bacteria , but not bacterial spores. The process was named after the French microbiologist, Louis Pasteur , whose research in the s demonstrated that thermal processing would deactivate unwanted microorganisms in wine. Today, pasteurization is used widely in the dairy industry and other food processing industries to achieve food preservation and food safety.

 - Беккер понял, что совершил какой-то промах. - Да, наше агентство предоставляет сопровождающих бизнесменам для обедов и ужинов. Вот почему мы внесены в телефонный справочник. Мы занимаемся легальным бизнесом. А вы ищете проститутку.  - Слово прозвучало как удар хлыста.

 - Посмотрим, что у них. Соши начала просматривать документ. Ей попалось описание нитрата мочевины, в десять раз более мощной взрывчатки, чем динамит.

 - Я люблю. Я люблю. В этот момент в тридцати метрах от них, как бы отвергая мерзкие признания Стратмора, ТРАНСТЕКСТ издал дикий, душераздирающий вопль. Звук был совершенно новым - глубинным, зловещим, нарастающим, похожим на змею, выползающую из бездонной шахты. Похоже, фреон не достиг нижней части корпуса.

 - Мы же говорим не о реверсии какой-либо сложной функции, а о грубой силе. PGP, Lucifer, DSA - не важно. Алгоритм создает шифр, который кажется абсолютно стойким, а ТРАНСТЕКСТ перебирает все варианты, пока не находит ключ.
