Preservation process

  • Generally, a process is defined as a sequence of events that transforms the biological materials of food products, via biochemical changes, into stable forms with added value. This can create new products or modify existing ones. Process design refers to the design of food processes and manufacturing methods, while plant design refers to the design of the whole processing plant. The processing of food is no longer as simple or straightforward as in the past. Food process design is an interdisciplinary science that is highly regarded by the food industry.

  • There are many excellent texts available which cover the fundamentals of food engineering, equipment design, modelling of food processing operations etc. There are also several very good works in food science and technology dealing with the chemical composition, physical properties, nutritional and microbiolog- ical status of fresh and processed foods. This work is an attempt to cover the middle ground between these two extremes.

  • This volume informs the reader about food preservation processes and techniques, product quality and shelf life, and the logistical packaging, packaging materials, machinery and processes, necessary for a wide range of packaging presentations. It is essential that those involved in food packaging innovation have a thorough technical understanding of the requirements of a product for protection and preservation, together with a broad appreciation of the multi-dimensional role of packaging.

  • The third edition is divided into five parts. Part one describes some important basic concepts. Part two describes unit operations that take place at ambient temperature or involve minimum heating of foods. Part three includes operations that heat foods to preserve them or to alter their eating quality. Part four describes operations that remove heat from foods to extend their shelf life with minimal changes in nutritional quality or sensory characteristics. Part five describes post-processing operations, including packaging and distribution logistics. ...

  • The increasing global demand for processed foods has led to a greater prominence of the food industry, its specific needs and processing challenges. Consequently, in recent times the role of the engineer in the food industry has gained considerable prominence. In contrast to other more traditional processing industries, the raw materials or ingredients that are used tend to be of greater complexity in nature.

  • Signal processing plays a key role in the optimization of disc capacity together with system margins of the optical drive. For the new format, new modulation codes have been designed for the rewritable version (parity-preserving code) and the read-only version (combi-code). For bit-detection in the rewritable format, a nonrecursive algorithm with PRML-like performance is devised. Finally, a new ECC code, called the picket code, was designed in order to cope with multiple long burst errors, on top of the usual random errors of the channel...

  • Freezing is one of the oldest and most commonly used means of food preservation. It has been known to be an extremely effective means of preserving food for extended periods since Paleolithic and Neolithic times, when man used ice and snow to cool food. The cooling effect of salt and ice was first publicly discussed in 1662 by the chemist Robert Boyle, but this technology was certainly known in Spain, Italy and India in the sixteenth century.

  • At its simplest, biotechnology is technology based on biology. From that perspective, the use of biological processes is hardly noteworthy. We began growing crops and raising animals 10,000 years ago to provide a stable supply of food and clothing. We have used the biological processes of microorganisms for 6,000 years to make useful food products, such as bread and cheese, and to preserve dairy products. Crops? Cheese? That doesn’t sound very exciting. So why does biotechnology receive so much attention?...

  • “Essentially, all life depends upon the soil. There can be no life without soil and no soil without life; they have evolved together.” - Charles E. Kellogg, USDA Yearbook of Agricul‐ ture, 1938. Natural processes and human activities alter the properties and quality of soils over time. The assessment of soil quality entails the evaluation of the capability of a soil to perform its functions not only in present scenarios but also how those functions can be preserved for future land...

  • Prior to the availability of refrigeration, foods, particularly fish and meat, were preserved by salting, marinating or pickling. Through a decrease in water activity, meat and fish were protected against microbial spoilage and other deteriorative processes. It was the process of treating meat with rock salt that led to modern curing practices (Cassens 1990). Thus, meat curing, historically defined as the addition of salt (sodium chloride) to meat, is now referred to as the intentional addition of nitrite and salt to meat.

  • Dynamical systems theory in mathematical biology and environmental science has attracted much attention from many scientific fields as well as mathematics. For example, “chaos” is one of its typical topics. Recently the preservation of endangered species has become one of the most important issues in biology and environmental science, because of the recent rapid loss of biodiversity in the world. In this respect, permanence or persistence, new concepts in dynamical systems theory, seem important.

  • It is more than a century since Karl Pearson invented the concept of Principal Component Analysis (PCA). Nowadays, it is a very useful tool in data analysis in many fields. PCA is the technique of dimensionality reduction, which transforms data in the high-dimensional space to space of lower dimensions. The advantages of this subspace are numerous. First of all, the reduced dimension has the effect of retaining the most of the useful information while reducing noise and other undesirable artifacts. Secondly, the time and memory that used in data processing are smaller.

  • Facilitating access is concerned with assisting people to command appropriate health care resources in order to improve or preserve their well-being. If services are available, then a population may ‘have access’ to health care provision. The extent to which access is gained can depend on administrative, political, social and cultural factors and barriers. The services available must be relevant and effective if people are to gain access to improved health outcomes.
