Book Description
The demand for agricultural production has been changing from quantitative stability to high qualitative standards. Especially in the first-growing Asian market, people now expect high standards in the quality of agricultural products, not cheap ones cultivated on a large scale any more. In this trend, it is important to maintain the safety and quality of agricultural products, which as organisms are also a challenge to handle as with other industrial products. This book offers comprehensive knowledge and technology to help assure and guarantee the high quality of agricultural products. The book analyzes and reviews product properties from physical and biochemical viewpoints, such as structure, dynamics, sound, electricity, and light. It also includes the design of processing machinery used in post-harvest operations, starting from harvest, preservation, processing, cooking, storage, to transportation and indispensable sorting techniques that include taste, smell, and freshness, notably the sweetness prediction of fruits with near infrared spectroscopy. This research study was developed in Japan, a leading country in the Asian market for high quality agricultural products, and it provides a full range of practical information for producing high quality agricultural products. The book covers comprehensive knowledge and technology applied to quality food preservation, as well as the safety and diversity in food. Contents include: Physical Properties of Agricultural Products * Structural Characteristics Related to Physical Properties * Fundamental Physical Properties * Thermal Properties * Mechanical Properties * Acoustic and Vibrational Properties * Electric Characteristics * Optical Properties * Biochemical Properties.

Book Description
This Encyclopedia of Agrophysics will provide up-to-date information on the physical properties and processes affecting the quality of the environment and plant production. It will be a "first-up" volume which will nicely complement the recently published Encyclopedia of Soil Science, (November 2007) which was published in the same series. In a single authoritative volume a collection of about 250 informative articles and ca 400 glossary terms covering all aspects of agrophysics will be presented. The authors will be renowned specialists in various aspects in agrophysics from a wide variety of countries. Agrophysics is important both for research and practical use not only in agriculture, but also in areas like environmental science, land reclamation, food processing etc. Agrophysics is a relatively new interdisciplinary field closely related to Agrochemistry, Agrobiology, Agroclimatology and Agroecology. Nowadays it has been fully accepted as an agricultural and environmental discipline. As such this Encyclopedia volume will be an indispensable working tool for scientists and practitioners from different disciplines, like agriculture, soil science, geosciences, environmental science, geography, and engineering.

Book Description
In any agricultural country, various types of agricultural commodities are produced in large quantities and to handle such quantities during harvest, post-harvest, processing and transportation, various types of equipment are required. To design particular equipment or determining the behaviour of the product for its handling, physical properties such as size, shape, surface area, volume, density, porosity are very important. Various types of cleaning, grading and separation equipment are designed on the basis of physical properties of seeds such as size, shape, specific gravity etc. The book will provide a fundamental understanding of engineering properties of agricultural produce and the knowledge of engineering properties are combined with engineering knowledge. Each chapter in the book will be helpful for the students to understand the relationship between engineering properties of raw, semi-finished and processed food to obtain products with desired shelf-life and quality. This book discusses basic definitions, principles of engineering properties and their measurement methods with research findings. It will be helpful to the students for their self-study and to gain information how to analyze experimental data to generate practical information. It will also be helpful for students who deal with engineering properties in their research. Methods to measure these properties are also explained in details.

Book Description
The importance of economical production of agricultural materials, especially crops and animal products serving as base materials for foodstuffs, and of their technological processing (mechanical operations, storage, handling etc.) is ever-increasing. During technological processes agricultural materials may be exposed to various mechanical, thermal, electrical, optical and acoustical (e.g. ultrasonic) effects. To ensure optimal design of such processes, the interactions between biological materials and the physical effects acting on them, as well as the general laws governing the same, must be known.The mechanics of agricultural materials, as a scientific discipline, is still being developed, and therefore has no exact methods as yet, in many cases. However, the methods developed so far can already be utilized successfully for designing and optimizing machines and technological processes.This present work is the first attempt to summarize the calculation methods developed in the main fields of agricultural mechanics, and to indicate the material laws involved on the basis of a unified approach, with all relevant physico-mechanical properties taken into account.The book deals with material properties, gives the necessary theoretical background for description of the mechanical behaviour of these materials including modern powerful calculation methods and finally discusses a large number of experimental results. Many of them can only be found in this book. Special attention is paid to the unified approach concerning theory and practice.The systematic treatment of the material makes the book useful to a wide circle of designers, researchers and students in the field of agricultural engineering. The book can also be used as a textbook at technical and agricultural universities.
