| Abstract (English): |
The araza, also known as quince or Amazon guava, is a climacteric fruit typical of the Ecuadorian Amazon region. The fruit has a vitamin A, B1, and C content of 7.75%, 9.84%, and 74%, respectively, with the vitamin C content being twice that of the orange. However, as a fruit that needs to be stored at 90% humidity, it is very perishable. Therefore, the current study was carried out to determine the physicochemical characteristics, thermal properties, and freezing time of the fruit through mathematical models using the RStudio software to simulate the freezing process and thus preserve the vitamin content. The arazá freezing time was 2.98 hr at –18ºC, which is well within the normal parameter for freezing fruits while maintaining their nutritional characteristics. [ABSTRACT FROM AUTHOR] |

El arazá conocido también como membrillo o guayaba amazónica es un fruto climatérico propio de la región amazónica ecuatoriana que posee un contenido de vitamina A, B1 y C de 7,75%; 9,84% y 74% respectivamente, sobresaliendo el contenido de vitamina C cuyo porcentaje es el doble que el que posee la naranja, sin embargo, al ser un alimento con un 90% de humedad es muy perecible, por lo que se determinaron las características físico – químicas, propiedades térmicas y tiempo de congelación de la fruta, mediante modelos matemáticos empleando el software RStudio para simular el proceso de congelación y de esta manera preservar el contenido vitamínico. El tiempo de congelación del arazá fue de 2,98 h a -18∘C y está dentro del parámetro normal para frutas en el cual se mantienen sus características nutricionales. [ABSTRACT FROM AUTHOR] |
