Se llevó a cabo en los distritos: Aramango, Copallín, El Parco, Imaza y La Peca. Se consideró una población de 234 fincas cacaoteras y una muestra estratificada de 70 fincas. En los frutos se analizaron características fisicoquímicas (peso, longitud, diámetro, granos, pH y ºBrix); sensorial (sabores básicos) y sus descriptores (color, forma, constricción basal y ápice). Se usó el Análisis de Componentes Principales para el desempeño de las variables. Los valores para el fruto respecto al peso y diámetro fueron mayores en La Peca y Aramango, respectivamente. Las características del grano predominantemente fueron dulces (más en La Peca) y con una longitud (> 1.2 cm) requerida para elaborar chocolates de calidad. Resaltó en el fruto el color amarillo (88.6%), forma elíptica (80%) y constricción basal ausente (71.4%).","PeriodicalId":42302,"journal":{"name":"Revista de la Universidad del Zulia","volume":"13 1","pages":""},"PeriodicalIF":0.3,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81725054","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Los resultados muestran que el total de sólidos disueltos según la norma NPDWR de USA, ubica el agua de la Laguna de Ñahuimpuquio en un nivel de calidad aceptable para suministro de red, y calidad aceptable para agua purificada de garrafón y/o agua embotellada. La salinidad en la laguna oscila entre 297,2 – 312,2 μS/cm; se considera dentro de los parámetros de Digesa (700 – 1200 μS/cm), lo que indica que la laguna tiene baja toxicidad de iones. La conductividad eléctrica del agua de la laguna muestra valores entre (282 – 303,6 de CE), clasificándose como “Buena”. En cuanto a la temperatura, los resultados muestran unos valores desde (18,52 °C – 24.66 °C).
