Starch is an abundant and readily available source of biological raw materials and is widely used in the food, medical and textile industries. For the characterization of the native state of white carrot (Arracacia xanthorrhiza), four different eco-pits (19001, 19012, 19086, 18994) and two sweet potato (Ipomoea batatas) eco-pits (Morado and Tocacita) were used. Study variables for each tuber were (amylose content, total starch, humidity, water adsorption index, solubility, swelling power and whiteness index). The results obtained through this research in the native state differ from each other in the ecotypes white carrot (Arracacia xanthorrhiza) and sweet potato (Ipomoea batatas), the chemical and physical modified starch were subjected to the same study variables to finally carry out a comparison of starch in its native state with modified starch and determining that the best method was physical modification since it presented a statistical difference from each other. |
