Efect of the storage on postharvest quality and antioxidant capacity of Syzygium paniculatum Gaerth
The Magenta tree (Syzygium paniculatum Gaertn), native to Australia, has been introduced and cultivated in several areas of Ecuador. Commonly known as Eugenia Fruit, it is primarily an ornamental plant. In Australia, this species is threatened or vulnerable. It produces medium-sized, round, brightly...

| description | The Magenta tree (Syzygium paniculatum Gaertn), native to Australia, has been introduced and cultivated in several areas of Ecuador. Commonly known as Eugenia Fruit, it is primarily an ornamental plant. In Australia, this species is threatened or vulnerable. It produces medium-sized, round, brightly colored fruits with a sweet, refreshing flavor. Despite being edible, its consumption is rare due to a lack of knowledge about its characteristics. It is cultivated primarily for its decorative value in gardens and landscapes, appreciated for its lush foliage. This study evaluates the effect of different storage treatments (20°C and 7°C, 0 and 15 days) on the physicochemical properties and antioxidant capacity of Syzygium paniculatum. Parameters such as color, size, fresh weight, diameter, seed weight, edible portion, acidity, and pH were analyzed, as well as general characteristics and chemical composition (humidity AOAC 934.05; ash AOAC 940.26; protein by Kjeldahl method AOAC 920.152; fat AOAC 948.22; fiber AOAC 945.38; carbohydrates by calculation). During storage, weight loss, respiration rate, and antioxidant activity of the fruit were investigated. The purpose is to provide relevant information to optimize storage practices, preserving the nutritional, functional, and visual quality of the fruits, and thus maximize their potential as a functional food or ingredient in various food industries. |

Conocido comúnmente como Fruto de Eugenia, es principalmente una planta ornamental. En Australia, esta especie se encuentra amenazada o vulnerable. Produce frutos medianos, redondos, de colores brillantes y sabor dulce y refrescante. A pesar de ser comestible, su consumo es poco frecuente debido al desconocimiento sobre sus características. Se cultiva mayormente por su valor decorativo en jardines y paisajes, apreciado por su follaje exuberante. Este estudio evalúa el efecto de distintos tratamientos de almacenamiento (20 °C y 7 °C, 0 y 15 días) sobre las propiedades fisicoquímicas y la capacidad antioxidante de Syzygium paniculatum. Se analizaron parámetros como color, tamaño, peso fresco, diámetros, peso de semilla, porción comestible, acidez y pH, además de características generales y composición química (humedad AOAC 934.05; cenizas AOAC 940.26; proteína por el método Kjeldahl AOAC método 920.152; grasa AOAC 948.22; fibra AOAC 945.38; carbohidratos por cálculo). Durante el almacenamiento, se investigaron la pérdida de peso, la tasa de respiración y la actividad antioxidante del fruto. El propósito es proporcionar información relevante para optimizar las prácticas de almacenamiento, preservando la calidad nutricional, funcional y visual de los frutos, y así maximizar su potencial como alimento funcional o ingrediente en diversas industrias alimentarias.Ingeniero/a en Agroindustria AlimentariaUniversidad de Investigación de Tecnología Experimental YachayCoronel Feijó, Manuel AlbertoCarrera Cevallos, Jeanette Verónica2025-10-16T21:16:07Z2025-10info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/bachelorThesisapplication/pdfhttps://repositorio.yachaytech.edu.ec/handle/123456789/1011eninfo:eu-repo/semantics/openAccessreponame:Repositorio Universidad Yachay Techinstname:Universidad Yachay Techinstacron:Yachay2025-10-17T07:00:12Zoai:repositorio.yachaytech.edu.ec:123456789/1011Institucionalhttps://repositorio.yachaytech.edu.ec/Universidad públicahttps://www.yachaytech.edu.ec/https://repositorio.yachaytech.edu.ec/oaiEcuador...opendoar:102842025-10-17T07:00:12falseInstitucionalhttps://repositorio.yachaytech.edu.ec/Universidad públicahttps://www.yachaytech.edu.ec/https://repositorio.yachaytech.edu.ec/oai.Ecuador...opendoar:102842025-10-17T07:00:12Repositorio Universidad Yachay Tech - Universidad Yachay Techfalse |
