This book is a result of practical research in Food Science and Technology.Cocoyam are the third most important root crop (after yam and cassava) cultivated in West Africa.The major limiting factor in the utilization of cocoyam is the presence of phytochemical and anti-nutrient,which impart taste or cause irritation when foods prepared from them are eaten.The levels of these nutrients in locally grown cocoyam are important in the assessment of their nutritional status,"taro" in their raw forms are toxic,hence processing can help to simultaneously reduce the anti-nutritional contents and enhance mineral bioavaliability.This book is intended to assist processors, researchers in utilization of this underutilized food crop.
