Estudio bromatológico de Disterigma empetrifolium (Kunth) Drude y su adición en una barra energética

Abstract

The main objective of this research is to study the bromatological characteristics of Disterigma empetrifolium (Kunth) Drude and its addition in an energy bar. The idea was born to use these fruits of native species of Ecuador and to incorporate them in a nutritious diet for people. Disterigma empetrifolium (Kunth) Drude (chirimote) is a species of the Ericaceae family. The fruits were collected in the Teligote hill - Pelileo, province of Tungurahua. It contains high amounts of vitamin C, potassium, iron, total sugars and dietary fiber. The next step was to obtain an energy bar based on D. empetrifolium, for the formulations an AxB factorial design was used, in combination with dehydrated chirimote fruit and panela honey where 6 treatments were obtained. The acceptability of the product was then evaluated and ANOVA and multiple range tests (Tukey) were carried out, where it was observed that there was a significant difference between the treatments, indicating that Treatment 4 was the best (20 percent dehydrated fruit of D. empetrifolium and 15 percent panela honey). Bromatological analyses were carried out, which indicated that per 100g of product in percentage there is 8.25 moisture, 2.10 ash, 7.73 protein, 11.1 fiber, 6.71 fat, 64.11 carbohydrates and 347.75 kcal of caloric energy. On the other hand, evaluating the microbial quality of molds, yeasts, total coliforms and E. coli, indicating that they are within the limits established by INEN 2595.
