Conversion of sweet potato to starch should be especially attractive to developing countries because it can help to lessen the need for imported materials, which reduces import bills (Garcia and Walter, 1998). For example, sweet potato accounted for 26% of starch production in Asia, and the global SPS production of 4.15 million metric tonnes in the early 1990s came from Asia (Ostertag, 1993). SPS is widely used in a variety of food and industrial applications in Asia (Tian et al, 1991). An industry based on SPS extraction has been developed in several regions in China (Li et al, 1991) and may account for more than two million tonnes annually, but the statistics are not quite precise (Wheatley and Bofu, 2000). The starch is utilized primarily... 

In recent years, the conversion of starch to fructose has become a very important commercial process. High-fructose corn syrup (HFCS) is approximately twice as sweet as sucrose. It is used in soft drinks, canned fruits, lactic acid beverages, juice, bread, ice cream, frozen candies, and so on. HFCS can be obtained from a variety of cereals and vegetables, such as corn, wheat, rice, potatoes, and cassava. Corn is the most important source of HFCS because of low costs and excellent utilities of its by-products, corn meal, oil, gluten, germ, and fiber.
