Use of nopal dietary fiber in a powder dessert formulation. The development of diverse types of foods of low caloric value and with high content in dietary fiber have occupied a preponderant place in the food industry in the last years, due to the growing interest of the consumers for a healthy and nutritious diet. Pre-cooked or quick to prepare foods are attractive for the time they save; if to this you add their nutritious value, the attractiveness is even greater. For this reason, this study analyzes different formulations of a powder to prepare a dessert (flan), with different percentages of incorporation of nopal flour, as a source of dietary fiber (16, 18, 20%). Two flavors (melon and banana) were tried. It was observed that the flan flavored with banana and with 16% of nopal flour, reached better sensorial characteristics. Greater percentages of nopal flour negatively affected the sensorial characteristics, mainly flavor, color and texture. The analysis showed that the powder presented 5,7% of moisture, low water activity (0,48) and therefore a low total recount of microorganisms. The content of protein was high (27,2%), the ether extract low (2,0%) similar to the caloric contribution (40 Kcal/ portion). The flan showed a 9,8% of total dietary fiber, being greater the contribution of soluble fiber (6,1%)than that of insoluble fiber (3,7%). Due to these characteristics this formulation could be considered as a food that provides benefits for the human health.
