    Ecuador is one of the 17 megadiverse countries in Andean tuber and root crops that over time have been industrialized in the production of flour. Currently, the population includes vegetable flours in their daily diet, which have high nutritional value, dietary fiber, starch, minerals, vitamins, carbohydrates, and lipids necessary to provide energy to the body. It is worth mentioning that high consumption of saturated fats can lead to cardiovascular diseases. Therefore, the purpose of this research was to determine the lipid profile of chinese potato (Colocasia esculenta) and white carrot (Arracacia xanthorrhiza) flours to establish saturated and unsaturated fatty acids, in order to identify the nutritional quality of these flours and guarantee a healthy diet. The fat component in Chinese potato and white carrot flour was extracted by Soxhlet equipment with results of 0.40 plus minus 0.04 percent and 0.84 plus minus 0.08 percent, respectively. The lipid profile was determined by gas chromatography with flame ionization detector, identifying the main fatty acids: palmitic acid (30.83 percent and 18.68 percent); oleic acid (28.53 percent and 15.97 percent) and linoleic acid (40.64 percent and 65.35 percent). Quality indexes were also established that indicated that they were good flours for inclusion in the daily diet.
