Sweet Potatoes

 

Agrofood had the opportunity to be the first in Egypt to join an American project and develop a virus free sweet potato seedling. This project has proven to be very successful and today our sweet potato farms in Nubaria and near Alexandria export 1500 M/T specifically to the UK and other markets according to demand variation.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

   

     

 

 

About Nutrition

 

Besides simple starches, sweet potatoes are rich in complex carbohydrates, dietary fiber, beta carotene (a vitamin A equivalent nutrient), vitamin C, and vitamin B6. Pink, yellow and green varieties are high in carotene, the precursor of vitamin A.

In 1992, the Center for Science in the Public Interest compared the nutritional value of sweet potatoes to other vegetables. Considering fiber content, complex carbohydrates, protein, vitamins A and C, iron, and calcium, the sweet potato ranked highest in nutritional value. According to these criteria, sweet potatoes earned 184 points, 100 points over the next on the list, the common potato.

Sweet potato varieties with dark orange flesh have more beta carotene than those with light-colored flesh, and their increased cultivation is being encouraged in Africa, where vitamin A deficiency is a serious health problem. Despite the name "sweet", it may be a beneficial food for diabetics, as preliminary studies on animals have revealed it helps to stabilize blood sugar levels and to lower insulin resistance.

The peptic substance (0.78 percent total, 0.43 percent soluble) present in fresh tubers contains uronic acid (60%) and methoxyl (4-5%). Other constituents include phytin (1.05%), two monoaminophosphatides (probably lecithin and cephalin), organic acids (oxalic acid), phytosterolin, phytosterol, resins, tannins, and coloring matter.
