Book Description
The diverse segments of the snack industries that generate close to $520 billion of annual sales are adapting to new consumer ́s expectations, especially in terms of convinience, flavor, shelf life, and nutritional and health claims. Snack Foods: Processing, Innovation, and Nutritional Aspects was conceptualized to thoroughly cover practical and scientific aspects related to the chemistry, technology, processing, functionality, quality control, analysis, and nutrition and health implications of the wide array of snacks derived from grains, fruits/vegetables, milk and meat/poultry/seafood. This book focuses on novel topics influencing food product development like innovation, new emerging technologies and the manufacturing of nutritious and health-promoting snacks with a high processing efficiency. The up-to-date chapters provide technical reviews emphasising flavored salty snacks commonly used as finger foods, including popcorn, wheat-based products (crispbreads, pretzels, crackers), lime-cooked maize snacks (tortilla chips and corn chips), extruded items (expanded and half products or pellets), potato chips, peanuts, almonds, tree nuts, and products derived from fruits/vegetables, milk, animal and marine sources. Key Features: Describes traditional and novel processes and unit operatios used for the industrial production of plant and animal-based snacks. Depicts major processes employed for the industrial production of raw materials, oils, flavorings and packaging materials used in snack food operations. Contains relevant and updated information about quality control and nutritional attributes and health implications of snack foods. Includes simple to understand flowcharts, relevant information in tables and recent innovations and trends. Divided into four sections, Snack Foods aims to understand the role of the major unit operations used to process snacks like thermal processes including deep-fat frying, seasoning, packaging and the emerging 3-D printing technology. Moreover, the book covers the processing and characteristics of the most relevant raw materials used in snack operations like cereal-based refined grits, starches and flours, followed by chapters for oils, seasoning formulations and packaging materials. The third and most extensive part of the book is comprised of several chapters which describe the manufacturing and quality control of snacks mentioned above. The fourth section is comprised of two chapters related to the nutritional and nutraceutical and health-promoting properties of all classes of snacks discussed herein.

Book Description
This book focuses on the development of four key issues in the development of modern Spain; knowledge, manufacturing, energy and telecommunications, and public works. If technology transfer from advanced nations to less developed systems always worked, then the whole world would now be rich. That this is not the case is so obvious, we might well expect that the history of the processes, successes and failures of technology transfer across nations would be a very well-established field of enquiry. In fact, the theme is still a developing one, and the present Special Issue centres on the case of Spain as exemplary in many respects. The collected essays focus upon the four major themes of knowledge, manufacturing, energy, and telecommunications and public works. Essays range in time from the 18th century to the present time, from studies of espionage and early links between craftsmen and savants, to the institutions of technology (from training systems, to private enterprise activity, or patents), to case-studies of silk manufacture, shipbuilding, mining, paper-making, and pharmaceuticals. Each essay offers a broad variety of material to bring to bear on a major problem of world development, past, present, and future.
