(Universidad Privada Norbert Wiener, 2024-12-13) Altamirano Rimarachín, Néstor; Espinoza Rado, Erika Paola
Objetivo General: Analizar la capacidad antioxidante y el contenido de vitamina C de la pulpa de la fruta Sanky, Corryocactus brevistylus, proveniente de dos departamentos del Perú. Material y Método: Las muestras de la fruta Sanky, Corryocactus brevistylus, fueron obtenidas de los departamentos de Arequipa y Ayacucho y trasladados en cadena de frio al laboratorio en Lima, para el análisis físico - químico. Además, para el recojo de dicho fruto, se esperó la temporada de cosecha, los meses de junio y julio 2023. Para dicho análisis físico - químico de la fruta Sanky, proveniente de dos departamentos del Perú, se plantea una hipótesis bilateral. Se quiere demostrar la diferencia significativa en ambas muestras para inferir estadísticamente los resultados mediante el uso del software estadístico RStudio. Resultados: Se determinó por medio de análisis físico-químico, la capacidad antioxidante, Vitamina C, pH y grados brix dando los siguientes resultados: Muestra de Arequipa, capacidad antioxidante: 62387 exp. En micromol de trolox/100g. y en la muestra de Ayacucho, fue en promedio 52661.9 micromol de trolox/100g. La vitamina C para la muestra de Arequipa fue de 31mg/100g. Y en la muestra de Ayacucho en promedio fue 30mg/100g. En el pH en la muestra de Arequipa fue 3.2 y la muestra de Ayacucho en promedio fue de 3.1. Finalmente, en los sólidos solubles en promedio para la muestra de Arequipa fue 5.4 y la muestra de Ayacucho fue de 5.8 respectivamente. Conclusiones: El estudio se realizó en muestra fresca de la pulpa de la fruta Sanky, Corryocactus brevistylus, según la hipótesis planteada a un 95% de confianza se infiere que hay diferencia significativa en las dos muestras de la fruta Sanky procedente de los departamentos del Perú. La capacidad antioxidante y la vitamina C es mayor en la muestra de Arequipa que en la muestra de Ayacucho. En cuanto al pH en la muestra de Arequipa es ligeramente mayor al de Ayacucho.

Results: The study included a total of 74 products, subdivided into juice, drinks, and nectar categories. It was found that 17.6% (n=13) of the products were juices, 71.6% (n=53) were drinks, and 10.8% (n=8) were nectars. Regarding compliance with technical parameters, there was a difference in the critical nutrient sugar, with 70.3% (n=52) of the sample meeting the Ministry of Health (MINSA) parameters and 16.2% meeting the Pan American Health Organization (PAHO) standards.
