never, ever" are rather often placed between the particle "to" and the infinitive.

For example, look at this sentence: She always tried to really understand young children and their hopes and fears. If we move "really" to some other places, the meaning will change, the construction will become awkward or incorrect: always really tried to understand; always tried really to understand; to understand really young children; to understand young children and their hopes and fears really.

never, ever" довольно часто помещаются между частицей "to" и инфинитивом.

Например, посмотрите на это пред-

ложение: She always tried to really understand young children and their hopes and fears. (Она всегда стара-

лась действительно понять маленьких детей и их надежды и страхи.) Если мы передвинем "really" в другие места, значение изменится, конструкция станет громоздкой или не-

правильной: always really tried to understand; always tried really to understand; to understand really young children; to understand young children and their hopes and fears really.

Food Quality Measurement Instruments

An important aspect of food processing and food preparation is the topic of food quality control. Food quality in a production setting can be degraded and compromised by any number of contributing factors, the most common of which include the presence of :

Pesticides

Pathogens

93

Heavy metals

Organic toxins

Foreign objects

In addition to these factors, food quality needs to be validated in terms of nutritional content and consistency, be assessed for the presence of allergens, verified with respect to adulteration and certification for GMO, and tested for shelf life.

There are a number of instruments used in food laboratories that can be applied to assure food quality which applies to solids as well as beverages. Some of the most common examples of these instruments and their use are described below.

Translate from English into Russian Colony Counters

Biological procedures often rely on an accurate count of bacterial colonies and cells. Colony counters are used to estimate a liquid culture’s density of microorganisms by counting individual colonies on an agar plate, slide, mini gel, or Petri dish. Typical applications include Ames testing, bacterial mutation assays, and E. coli bacterial colonies. Instruments accommodate various sizes and formats, including units that can scan plates up to 300 × 300 mm, and are optimized for use with UV illumination, white light, fluorescent, and/or Green Fluorescent Protein colonies. The counting can

97

be accomplished manually, often with touch pressure and a digital counter, or can be semior fully automatic. With automatic counters, improvements center on increasing precision and accuracy, such as the ability to detect smaller colonies in low-contrast media, illumination systems that increase visibility, direct image scanning and analysis capability, rapid multiplezone bioassay plate analysis, and IQ/OQ documentation.

Сахарная промышленность

Историческисложилось, чтосахарнаяпромышленностьявляетсяосновной отраслью, где используются поляриметры: благодаря этому за ними закрепилось ещё одно название – «сахариметры». Так, практически все мировые производители выпускают модели поляриметров, предназначенныеспециальнодлясахарного производства. Автоматический поляриметр – незаменимая вещь на сахарном заводе, его используют для измерения содержания сахарозы в сырье, далее во всех полупродуктах, в готовой продукции и, наконец, в отходах производства. Поляриметр-сахариметр позволяет измерить содержание сахарозы во всех сахаросодержащих продуктах от 0 до 100 % к массе продукта: это может быть сам сахар, меласса, свекловичный жом, барда и сточные воды. Стандарты международной комиссии ICUMSA предполагают использование длины пути (кюветы) 200 мм. и международную сахарную шкалу (МСШ). Этистандартытакжеописывают методытемпературной коррекции для сахарозы и многое другое. Для тёмных образцов применяются либо 100 мм. кюветы, либо источник света с большей длиной волны (как правило, 882 нм).

Additional Equipment

Function

Utility equipment provides the resources necessary for operating and maintaining a food processing facility, such as pumps, generators, power supplies, and combustion equipment.

Typical resources include electricity, heat, water, steam, compressed air, and waste disposal options.

Measurement and control equipment is used to ensure that the food processing equipment operates correctly, and the food processing stages proceed as specified. These instruments can be used to analyze ingredients and machines, as well as allow manufacturers to perform and duplicate processing procedures. They can also be used to monitor existing systems and machinery, such as logging data during product testing or quantifying typical performance statistics. Measurement devices are particularly crucial during food production, as minor changes in cooking temperature, ingredient ratios, and operation times can lead to drastic changes in the finished product. Some of the measurement and control devices commonly used for food processing include:

Precision controls

Pressure gauges

Scales and weighing systems

Thermometers

Timers

Material handling equipment is used to transport food material through and between preparation, processing,

and post-processing stations. Types of equipment used for material handling in the food and food processing industries include:

Conveyors systems

Fluid transport devices (e.g., pumps, hoses, tubes, and piping)
