Acetylation of Cassava Starch Using Perchloric Acid Catalysis

Abstract: Acetyl and propionyl derivatives of cassava starch were prepared using perchloric acid catalysis. The temperature for obtaining optimum yield and degree of substitution (DS) was 30°C. The clarity and sol stability of the derivatives are improved, while viscosity is reduced.

Nutritional, Functional and Physical Properties of Extrudates from Blends of Cassava Flour with Cereal and Legume Flours

Abstract: Low protein and poor functionality limit the use of cassava flour in snack foods, which were modified using blends with cereal and/or legume flours. Native, malted (using alpha-amylase) as well as malted and pre-gelatinized was blended with cereal (finger millet and whole wheat flours) and/or legume (chick pea flour). Extrudates were prepared at a screw speed of 100 rpm and die temperature of 180 °C. Malted flour based extrudates had lower starch content than native flour. Gram malted cassava based blends gave products with the highest protein. In vitro starch digestibility was the highest for pre-gelatinized flour based mixes. Extrudates with low fat and energy have scope as low calorie snacks for obese and diabetic people.

Economics of Sweetpotato Production and Marketing

Abstract: The major Roots and Tubers, Cassava, Potato, Sweetpotato and Yam occupied about 53.93 million ha world wide, producing 736.747 million tonnes annually (FAO, 2008). Individually Cassava, Potato, Sweetpotato and Yam rank among the most important food crops worldwide and in terms of annual volume of production. Cassava, Potato and Sweetpotato rank among the top ten food crops produced in developing countries. Many of the developing world’s poorest producers and the most undernourished house holds depend on roots and tubers as an important source of food and nutrition (Scott et al., 2000). Roots and tubers produce large quantities of energy per day, in comparison of cereals. Sweetpotato is an important tropical root and tuber crop as it ranks second after cassava among the tropical tuber crops. The crop can be considered promoting nutritional security particularly in agriculturally backward areas. Besides carbohydrates, it is a rich source of protein, lipid, calcium and carotene. It becomes an ideal crop for popularisation in areas with poor soils and poor agricultural infrastructure facilities. In annual production, sweetpotato ranks as the fifth most important food crop on a fresh-weight basis in developing countries after rice, wheat, maize, and cassava. Sweetpotato is cultivated in 114 countries and ranks among the five most important food crops in over 50 countries. Asia has the world’s major production area for sweetpotato. In Asia, the greatest share of production is in China that accounts for about 85% of global production. Feed, processed food and other non-food uses for sweetpotato expanded considerably in Asia over the last three decades (Pham et al., 1996; Scott, 1992; Titapiwatanakun, 1998). Rapid growth in demand for meat has created growth opportunities in more remote areas to use Sweetpotato as animal feed like in Sichuan province, China (Huang, 1999).
