Aprovechamiento de cultivos andinos camote (Ipomoea batata) y oca (Oxalis tuberosa) en el mejoramiento de la textura de una compota a base de manzana variedad emilia (Malus communis – Reineta amarilla de Blenheim)

Abstract

In order to determine the effect of the addition of Andean tubers (RTAs) cured by solar radiation in an apple compote of the Emilia variety (Malus communis - Reineta amarilla de Blenheim), rheological parameters (flow behavior index and consistency index), these parameters were adjusted to the power law, with respect to the mixtures based on a 45 percent established with a minimum in the Technical Standard INEN 2009: 2013. The rheological parameters of this type of product established that when the RTAs are added in different proportions, the flow index is n less than 1, this parameter determines that the lower it is, the greater its pseudoplasticity. Regarding the consistency index, the best treatment turned out to be T1 (22.50 percent Apple, 9.00 percent Sweet Potato, 13.50 percent Oca) since it presents high values during the ten days of analysis 11.03 Pa.s n the same ones that indicate that the mixture is the most adequate to maintain the appropriate characteristics of the compote. The additional parameters that were analyzed, in the apple, sweet potato and goose compotes, determined that the best treatment remains stable during the analysis and presents the best organoleptic characteristics accepted by the tasters. The useful life of the best treatment under normal conditions (18 degrees Celsius), is 24 days based on microbiological analysis (molds and yeasts), the intrinsic characteristics of the compote such as pH, Temperature, relative humidity, and pressure exert variation in the useful life time.
