This bulletin presents both theoretical and practical information on the processing of fruit and vegetable juices, thus offering the reader both the principles and practices of small and medium-scale fruit juice processing.The purpose of this publication is to fill the gap in information available to professionals as well as private entrepreneurs, mainly in developing countries. It is the medium and small-scale agro-industries that more appropriately fill the needs and capabilities of these countries, considering the available volume of production and the capacity of local markets to absorb products.
