Abstract
El presente trabajo se realizó en Chao, provincia de Virú, región La Libertad; se planteó como objetivo determinar Calidad de la fruta en cosecha Vaccinium corymbosum L. variedades Biloxi y Terrapin. Para ello, durante seis semanas de la fruta cosechada por día, se tomó al azar 5 jarras con frutos recién cosechados y de cada jarra en forma aleatoria se extrajo una muestra de 20 frutos, obteniéndose un total de 100 frutos como unidad de muestreo para determinar frutos con calidad de exportación y frutos de descarte. Como variables de evaluación, para frutos de descarte se consideró frutos rojos, desgarrados, deshidratados, con pedúnculo y/o corola, blandos, negros o sin bloom, deformes y picados por ave. Para frutos con calidad de exportación se consideró solidos solubles en grados Brix, acidez y volumen de producción. Se determinó en las variedades Biloxi y Terrapin más del 95.63 y 97.33 % de fruta con calidad de exportación. El descarte en ambas variedades fue bajo, los frutos clasificados en esta categoría y que alcanzaron mayor proporción fueron frutos desgarrados, frutos rojos y frutos deformes. Solamente, se observó frutos con pedúnculo y/o corola y picados por ave en la variedad Biloxi.
ABSTRACT This work was carried out in Chao, Virú province, La Libertad region; The objective was to determine the quality of the fruit in harvest Vaccinium corymbosum L. Biloxi and Terrapin varieties. For this, during six weeks of the fruit harvested per day, 5 jars with freshly harvested fruits were randomly taken and a sample of 20 fruits was randomly extracted from each jar, obtaining a total of 100 fruits as a sampling unit to determine fruits with export quality and discarded fruits. As evaluation variables, for discarded fruits, red fruits, torn, dehydrated, with peduncle and/or corolla, soft, black or without bloom, deformed and chopped by birds were considered. For fruits with export quality, soluble solids were considered in Brix degrees, acidity and production volume. It was determined in the Biloxi and Terrapin varieties more than 95.63 and 97.33% of fruit with export quality. The discard in both varieties was low, the fruits classified in this category and that reached a higher proportion were torn fruits, red fruits and deformed fruits. Only fruits with peduncle and/or corolla and chopped by birds were observed in the Biloxi variety.
