“…By using a near infrared spectroscopic technique, Schmilovitch et al (2000) predicted total soluble solid and acid content in mango with R 2 of 0.93 and 0.61 respectively. Employing the same technique, Slaughter et al (2003) predicted soluble solids content of prunes with R 2 =0.96, Kawano et al (1995) predicted brix content of peach with R 2 =0.92, and Guthrie and Walsh (1997) predicted brix content of mangoes with R 2 =0.81. Therefore, results of this study clearly indicate that the method developed can be used to predict chemical attributes (i.e., soluble solid and total acid contents) and maturity of mango with a high degree of accuracy.…”

Mango (Mangifera indica L.) is an important tropical fruit that has great potential in international markets. Currently, major markets for mango include North America, Europe, and Japan. The acceptance of exported mango in destination countries depends largely on eating quality, which is affected by maturity at harvest. Mango maturity can be judged visually, based on skin color, or determined chemically based on soluble solids content, acid content, and solids:acid ratio. Maturity determination based on visual observation is unreliable and prone to errors. On the other hand, determination based on sugar or soluble solids to acid ratio is destructive. Therefore, it is important to develop a simple, reliable and non-destructive technique for mango maturity determination. In this study, a reliable and non-destructive technique has been developed and tested. This technique uses a digital camera to capture an image of the mango skin. Images obtained were analyzed using an image processing software (Adobe Photoshop) to obtain color parameters (L, a, b values). Each of the color parameters was plotted against soluble solids content, total acid content, and solids:acid ratio and curve fitting was then applied to obtain polynomial equations. Results indicate that the color parameters can adequately predict the above maturity indices and, therefore, can be used to predict maturity of mango.

“…Los SS del fruto de ciruela, que tienen un valor cercano a los 7,26º Brix a los 32 días de iniciar su desarrollo, alcanzan un valor de 11,80º Brix el día de la cosecha, valor inferior al reportado para las variedades President (Valero et al, 2003), French (Slaughter et al, 2003) y similares a la variedad Blackamber (Crisosto et al, 2004). La AT, cuyo valor es de 0,84% el día 32, decrece a un valor de 0,78% el día 99, considerado alto respecto a variedades cosechadas en países subtropicales, sugiriendo la influencia de las condiciones climáticas, como también fue encontrado por Abdi et al (1997).…”

RESUMEN: El presente trabajo tuvo como objetivo determinar algunas propiedades físicas y fisiológicas de la ciruela variedad Horvin, durante el periodo precosecha, cuyo conocimiento es indispensable para la determinación del momento oportuno de recolección, lo cual permitirá reducir las pérdidas que se presentan de este producto durante la cosecha, debido a su deficiente manejo. El estudio permitió determinar que la ciruela variedad Horvin debe recolectarse 99 días después de la floración, en cuyo momento presentó valores medios de firmeza de 50,66 N, acidez HARVEST INDEX DETERMINATION OF PLUMS cv. HORVINABSTRACT: This research was carried out to determine some physical and physiological properties of plum (Prunus domestic L.) cv. Horvin, during the pre-harvests period, whose knowledge is indispensable to determine the appropriate harvest time, which will allow reducing the losses of this product during the harvest, due to his deficient handling. The study allowed determining that the plum cv. Horvin must be harvest 99 days after flowering. El sector agrícola colombiano afronta una serie de desafíos como consecuencia de su incorporación a la economía mundial de mercados, la cual exige productos y servicios de alta calidad, con valor agregado, mayor nivel de complejidad tecnológica y empleo de tecnologías limpias en su proceso de producción. Así, surge el reto de buscar sistemas diversificados y sostenibles que generen una mayor productividad, basada en la utilización de los recursos propios y tecnologías apropiadas, que sin afectar negativamente los ecosistemas permitan satisfacer las necesidades de una población en aumento.El municipio de Nuevo Colón (Boyacá), ubicado en la Región Andina Colombiana, está conformado por 16 veredas, en las que predomina la vocación agrícola (predios de minifundio). Según el Ministerio de Agricultura y Desarrollo Rural (2006), para el año 2005 existían 2165 ha dedicadas a frutales caducifolios, de los cuales la ciruela ocupa el segundo lugar en importancia, con un área cultivada de 500 ha y rendimientos de 3,0 a 4,5 Mg ha -1 . Las tecnologías de manejo cosecha y poscosecha utilizadas por los fruticultores de Nuevo Colón, presentan una serie de inconvenientes tales como deficiencias en los sistemas de recolección, equipos y herramientas inadecuados para la recolección y el manejo poscosecha, condiciones de almacenamiento deficientes, lo cual origina una pérdida en la calidad y cantidad del producto, disminuyendo el grado de competitividad en los mercados y afectando social y económicamente el nivel de vida de los productores, al ver disminuidos sus ingresos al comercializar los productos.Brady y O'Connel (1976) reportan que las frutas inician una serie de cambios una vez son cosechadas, debido a la actividad enzimática y síntesis de proteínas, que en el caso de productos climatéricos afecta directamente el proceso de maduración. El cosechar tempranamente leva a una pérdida significativa en el rendimiento, pues en los últimos días de desarrollo la ciruela crece rápidamente hasta ...

Moreover, it can be applied to detect the presence of damaged tissue such as brownheart of Braeburn apple (McGlone et al, 2005), scald, scab tissue and recent bruise of Jonagold apple (Kleynen et al, 2003), and browncore of Chinese pear (Han et al, 2006), and to estimate physiological variables such as maturity of Pawpaw papaya (Greensill & Newman, 1999) and Scarlet apple (Bertone et al, 2012).…”

Near infrared spectroscopy (NIRS) can be applied to assess the quality of mango. The purpose of this research is to select the appropriate chemical absorption bands to evaluate two cultivars of mango puree, cv. Keitt and cv. Nam Dok Mai Si Thong. Six main chemical substances found in mango fruit, such as glucose, sucrose, citric acid, malic acid, starch and cellulose, were evaluated in this study and there chemical absorption bands were identified. Mango puree was mixed with the six pure substances at various concentrations; glucose, sucrose, citric acid and malic acid were tested with concentrations of 0, 5, 10, 15 and 20%w/w, starch and cellulose were tested with the concentrations 0, 2.5, 5, 7.5 and 10% w/w. The NIRSystem 6500 was used to scan the spectra in the wavelength range from 400 nm to 1100 nm. The partial least square regression (PLSR) was used to develop a model for each component. The result was a wavelength that corresponds to each component. It was found that the second derivative spectra of glucose, sucrose, citric acid, malic acid, starch and cellulose mixtures showed the best PLSR result. The mango cultivar had no effect on wavelength selection by PLSR model. The coefficient of determination (R 2 ) of all models was 0.99. The standard error of calibration (SEC) and the standard error of prediction (SEP) were less than 0.5%w/w. The regression coefficient plot exhibited more sharp peaks than pure substances. The wavelength selection for NIRS evaluation mango fruit quality could not be done by using only measured spectrum of pure substance. However, the cultivars of mango had no effected on wavelength selection by PLSR model. The most effective wavelength for glucose and sucrose were 900-1000 nm, citric acid and malic acid were 800-1000 nm, starch was 900-1000 nm and cellulose was 800-1000 nm.
