Abstract

The aims of this study were to evaluate the nutritional value of new hybrids sweet potato in order to raise public awareness of its potential use in nutrition and to formulate high protein quality weaning foods. The nutritional composition was determined for two new cultivar and local cultivar grown up in Horticulture Institute in El-Qanater El-Khyariya Egypt.
 The cultivars namely Minufiya 2/96 and Minufiya 9/96 were compared with local cultivar (Mabrouka). The results show that protein contents of new cultivar were greater than that of local cultivar. Protein levels were 9.78, 11.27 and 5.17% for Minufiya 2/96, Minufiya 9/96 and Mabrouka respectively. The new cultivar also were higher than the local cultivar  on total carbohydrates, total sugar, reducing sugar, non-reducing sugar and sucrose content .The results revealed that sweet potato might be mentioned as a source of antioxidant (Vitamin C and β-carotene). The concentration of β-carotene mg/100g F.W was 12.64, 10.20 and 6.76 for Minufiya 2/96, Minufiya 9/96 and Mabrouka respectively, and the content of Vit. C was 15.05, 20.47 and 17.59 mg/100g F.W. for Minufiya 2/96, Minufiya 9/96 and Mabrouka respectively.
Four weaning food mixture were formulated from sweet potato70%, ficus carica 10% and or peanut and chickpea or mung bean or soybean in the ratio (20%) respectively in the form of powder. Data indicate that these mixtures had higher protein quality and quantity .Formula 1 of weaning food mixture showed high acceptability for appearance, texture, odor, color and taste. Also it is cheap weaning foods, the average cost of 100 gram from .080 to 1.50L.E.
