Los factores que intervienen en la post cosecha del Tangelo  son la organización, extensión agrícola, accesibilidad al crédito agrario y la comercialización. El costo de producción promedio del Tangelo por hectárea sin post cosecha es de S/ 4 064,00  y la utilidad por campaña oscila entre S/ 818,00 a S/1 853,00 con una rentabilidad desde 20,54% hasta 44,68%. El costo de post cosecha promedio del Tangelo por hectárea es de S/18 912,00 con una utilidad desde S/ 4 999,00 hasta S/ 7 459,00 con una rentabilidad de 28,93% hasta 36,38% en la primera campaña. Para la segunda campaña la rentabilidad del tangelo con poscosecha se incrementó 61,49%.  Durante el tratamiento post cosecha se obtiene: 5% de descarte, 30% de calidad primera, 45% de calidad segunda y 20% calidad tercera. La presentación del producto es  en cajas de cartón corrugado de 40, 50 y 60 unidades según la calidad. Con la contrastación estadística se puede afirmar con 95% de seguridad que la rentabilidad es mayor en el Tangelo con post cosecha a partir de la segunda campaña. Se concluye que con la aplicación del tratamiento post cosecha en el Tangelo se logra incrementar la rentabilidad económica del agricultor el cual tendrá impacto en la ampliación de su frontera agrícola, alimentación, educación, vestimenta y salud.

Macrophomina phaseolina is one of the pathogenic organisms of gummosis disease of orange tree (Citrus reticulata). The pathogen was identified from the observation of their colony size, shape, colour, mycelium, conidiophore, conidia, hyaline, spore, and appressoria in the PDA culture. The crude chloroform extracts from the organism showed antibacterial activity against a number of Gram positive and Gram-negative bacteria. The crude chloroform extract also showed promising antifungal activity against three species of the genus Aspergillus. The minimum inhibitory concentration (MIC) of the crude chloroform extract from M. phaseolina against Bacillus subtilis, Staphylococcus aureus, Escherichia coli, and Shigella sonnie were 128 ?gm, 256 ?gm, 128 ?gm and 64 ?gm/ml respectively. The LD50 (lethal dose) values of the cytotoxicity assay over brine shrimp of the crude chloroform extract from M. phaseolina was found to be 51.79 ?gm/ml.

Siraitia Grosvenorii

The extraction yields of mogroside from Siraitia grosvenorii fruits and limonin from orange (Citrus reticulata Blanco) seeds were compared with different extraction methods, respectively. Maceration extraction, stirring extraction, ultrasonic extraction and flash extraction were used for the extraction. The extraction process was modeled using the concept of thin film which provides the resistance to transfer. The results showed that the maximum yields of mogroside (4.11%) and limonin (0.65%) were obtained by ultrasonic extraction and flash extraction respectively. Owing to its shorter extraction time, flash extraction would be an economical method for the mass production of triterpenes from natural products. The model was found to be fit for the comparison of methods for the extraction and provided good correlation of the data. The model could be mainly used in the practical extraction process.

Citrus Reticulata Blanco

Considering the huge economic loss caused by postharvest diseases, the identification and prevention of citrus postharvest diseases is vital to the citrus industry. In 2018, 16 decayed citrus fruit from four citrus varieties—Satsuma mandarin (Citrus unshiu), Ponkan (Citrus reticulata Blanco cv. Ponkan), Nanfeng mandarin (Citrus reticulata cv. nanfengmiju), and Sugar orange (Citrus reticulata Blanco)—showing soft rot and sogginess on their surfaces and covered with white mycelia were collected from storage rooms in seven provinces. The pathogens were isolated and the pathogenicity of the isolates was tested. The fungal strains were identified as Lasiodiplodia pseudotheobromae based on their morphological characteristics and phylogenetic analyses using the internal transcribed spacer regions (ITS), translation elongation factor 1-α gene (TEF), and beta-tubulin (TUB) gene sequences. The strains could infect wounded citrus fruit and cause decay within two days post inoculation, but could not infect unwounded fruit. To our knowledge, this is the first report of citrus fruit decay caused by L. pseudotheobromae in China.
