4.1 Introduction Minerals are the inorganic elements, other than carbon, hydrogen, oxygen and nitrogen, which remain behind in the ash when food is incinerated. They are usually divided into two groups – macrominerals and microminerals (or trace elements). The terms are historical in origin and originated at a time when the development of analytical equipment was still in its infancy and ‘trace’ was used to refer to components whose presence could be detected, but not quantified. Modern analytical equipment that allows determination of elements

3.1 Introduction Vitamins are classically defined as a group of organic compounds required in very small amounts for the normal development and functioning of the body. They are not synthesised by the body, or only in insufficient amounts, and are mainly obtained through food (Machlin and Huni, 1994). There are thirteen vitamins: four are fat-soluble, namely vitamins A (retinol)

A. Trichopoulou and A. Naska, University of Athens 2.1 Introduction Documenting and monitoring dietary patterns are priorities in nutritional epi￾demiology, in the planning of national food and nutrition policies and in the evaluation of nutrition education strategies. Early efforts in documenting dietary patterns were focused on identifying the specific nutrients that may be respon￾sible for effects on people’s health, but recently research has expanded towards studying patterns of food intake. Food data are often derived from:

Improving the nutritional quality of food is a key requirement for the food industry. There are a number of factors which have made this area one of growing importance, including:

Capital cost projects begin when a need is defined that cannot be satisfied in existing facilities. Thus begins the life cycle of a capital project (Fig. 1). Once started, the project will progress through all of the following phases or be canceled. It all starts with the recognition of a need that will require capital plant. In the conceptual phase of the project, multiple approaches will be evaluated and one or more plans will be evaluated for meeting these needs

The purpose ofthis chapter is to review various forms of solids dryers and auxiliary components. It is intended to be a practical guide to dryer selection (as opposed to the theory of drying, which is addressed in various technical manuals referenced in the bibliography). From a microscopic
