Adding value to cereals, roots and tubers (2) By Domien Bruinsma. Abstract. This study provides an overview of developments in storage and processing technologies for cereals, roots and tubers in Africa.

Root and Tuber Crops John Bradshaw Editor A number of root and tuber crops were first domesticated several thousand years ago, but none became important on a global scale until after the end of the 16th century. Today the potato is the world’s third most important food crop ( million tonnes produced in ), after wheat and : Hardcover.

In this book the value of roots, tubers, plantains and bananas in human nutrition and their importance in human diet is reviewed. The purpose of this book is to promote their production and utilization as valuable components of a well-balanced diet, and to alleviate hunger and seasonal food shortages. Staples of the tropics. The book deals with all aspects of cassava, sweetpotato, yams (Dioscorea spp.) and aroids (Colocasia spp and others), covering their origin, taxonomy, breeding, physiology, agronomy, pathology and gh they belong to different botanical families, roots and tubers are grouped together because they are vegetatively propagated, .   The energy from tubers is about one-third of that of an equivalent weight of rice or wheat due to high moisture content of tubers. However, high yields of roots and tubers give more energy per land unit per day compared to cereal grains. In general the protein content of roots and tubers is low ranging from 1 to 2% on a dry weight basis Cited by: Acrylamide level was above the European Commission indicative value in potato- and cereal-based food products, it ranged from to μg/kg in roots and tubers (potato and sweet potato). Among the cereals, maize ( μg/kg) and wheat ( μg/kg) had the highest and lowest contents, respectively, whereas rice, sorghum and Cited by: 2.

Tubers form at the base of roots, and store energy in the form of starch to support new stem growth for the plant. Examples of tubers include potatoes, Jerusalem artichokes, jicama, and yams. With wildly varying characteristics, and flavors ranging from earthy to sweet, roots and tubers are arguably the most nutritious, economical, and. Roots and tubers are considered as the most important food crops after cereals and contribute significantly to sustainable development, income generation and food security especially in the tropical regions. The perishable nature of roots and tubers demands appropriate storage conditions at different stages starting from farmers to its final consumers. In much of the developing world cereal grains such as maize, rice, wheat, sorghum and millet are the main food staples.

(), Hodges and Stathers This book is conceived to have an updated version on the tuber and root crops especially in the Indian context, including information on the history, biodiversity, geographical distribution, botany, neutraceutical and pharmaceutical values, new varieties, production technologies, IPM strategies, starches, post harvest technologies and value added products, bio-processing.
