Análisis nutricional comparativo entre snacks de Malanga (Xanthosoma saggitifolium) y Papa China (Colocasia esculenta) mediante la fritura convencional

The present research has as objective to compare the nutritional content of two types of snacks originated from non-traditional tubers as is the case of the dasheen and papa china crops that in Ecuador are not utilized in an optimal way, compared with a conventional snacks like is the potato. The evaluated components were: the protein content fats ashes, humidity, fiber, carbohydrates, the mineral content sodium and the energy intake, all these determinations were evaluated through the official analysis methods (AOAC). Likewise, the behavior of the oil in the frying by immersion of malanga, chinese patatoe and regular patatoe, putting the oil to 10 successive frying cycles; after the different cycles the physicochemical modifications were evaluated through determination of various parameters: refractive index, peroxide index, relative density and acidity index. Finally, we apply a sensory analysis through a test of acceptability with hedonic scale of 9 points. The program SPSS version 23 was applied, with the purpose of determining the statistical meanings of the effects of the variations. In the snacks, the “t of Student´s” for independent samples, with a 95% confidence, taking into account that these analyzes were carried out in duplicate, while in the case of the oils they were tests in triplicate, the date was subjected to an analysis of variance (ANOVA) followed by a Tukey test (p<0.05). The study determined that the values of the snacks of malanga and Chinese patatoe are an alternate source of nutrient compared with a conventional snacks, because their measures were highly variable like the case of the protein content. While the methods analyzed in the frying cycles showed that there is an increase in the values since the first frying, but this do not make any significant effect in the quality of the oil because the increase does not over pass the permitted limit by the rule INEN 0034. The snacks were liked by consumers so this project will get a good acceptance in the food market.
