Sweet potato: an untapped food resource
There is a Chinese saying 'When you have rice to eat, don`t forget sweet potatoes' and there is now increasing recognition of the potential which sweet potato holds for combating food shortages and malnutrition. This has resulted in intensified research efforts to enhance production and consumption. Sweet potato provides significant amounts of energy and protein and has a higher energy efficiency ratio than cereals when produced in a non-mechanized situation. Furthermore, even though the percentage of protein on a fresh weight basis is low in sweet potato and other roots and tubers, the average protein production per hectare from sweet potatoes is of the same order as that from cereals, beans and chickpeas. The book Sweet potato: an untapped food resource reviews the current knowledge about the varied aspects of the sweet potato as a human food and animal feedstuff. Examination of the chemical composition of the plant and analysis of its nutritional value emphasizes the important role that sweet potato can may in combating vitamin. A deficiency diseases. Effects of toxic factors and antinutritional components are also considered. Descriptions of curing, storage and cooking methods are complemented by a discussion of their effects on composition and nutritional value. The use of both roots and vines as animal feed is thoroughly reviewed and the possibilities and problems associated with enhanced consumption and utilization are discussed.
