| The white mulberry is a native fruit to China. The white mulberry as a fruit with high water content and sensitive texture, is a perishable fruit with high-level waste. To reduce the losses of the white mulberry, it used to be processed traditional dried fruit and mulberry molasses. The purpose of this study was to determine chemical and physical properties of white mulberry molasess made up of different cultivars, neutralizers and concentration methods. Two examples of cultivars were Bokhara and Khardar mulberry (local cultivars), two neutralizing compounds were white soil (traditionally special soil can be used as neutralization) and calcium carbonate, the concentration conditions were concentration under vacuum conditions and concentration under... |

| The aim of this study was to obtain the acerola juice using separation processes with membranes. The acerola pulp was initially defrosted and treated with 100 ppm of Citrozym Ultra L enzyme at 45ºC for one hour, then ultrafiltrated at 3 bar at 45ºC using 0.1 µm ceramic membrane, and concentrated by reverse osmosis using a spiral membrane of a compound film. The pressures on the reverse osmosis were 20, 30, and 40 bar at environmental temperature, thus, resulting a juice with 9.76, 14.56, and 17.36 ºBrix, respectively. The physicochemical characteristics of the juice were preserved and, studies on evaluation of the public acceptability, showed that 75% of the consumers liked the juice. |

| Abstract Tucupi, which is widely enjoyed in the North region of Brazil, is a fermented liquid derived from cassava (Manihot esculenta Crantz) and has been taken abroad for its exotic characteristics. This study aimed to assess the rheological behavior of tucupi with 30, 35, and 40% solids and concentrated at 50, 70, and 90 °C. The rheological data were obtained at 25, 40, 60, and 80 °C with increasing and decreasing shear rates. Rheology at 25 °C indicated that the partial gelification of starch during concentration causes a decrease in the product’s viscosity and, if the concentration is carried out at a temperature that favors total starch gelification, the product’s viscosity increases. Concentrated tucupi behaved as a pseudoplastic fluid, but at 60... |

| En el presente trabajo se evaluó la demanda nutrimental de las variedades de fresa Albión, Festival, Jacona y Zamorana, durante su ciclo de desarrollo, cultivadas bajo condiciones de túnel de plástico, en sustrato de fibra de coco y fertirriego, en la zona de Zamora, Michoacán. Se muestreó parte aérea mas corona, para determinar materia seca, concentración nutrimental y contenido nutrimental, durante un periodo de 165 días después del trasplante, con muestreos cada 15 días. En la acumulación de materia seca se observaron algunas diferencias entre variedades a partir del día 90, con mayor contenido de biomasa aérea más corona para Jacona y Festival, menores para Albión e intermedias para Zamorana. La concentración nutrimental presentó variaciones en el... |

| Se evaluó el efecto de seis concentraciones de conidios de Penicillium digitatum con el objetivo de determinar la concentración óptima que permita 100% de infección en frutos de limón persa en postcosecha. El hongo se aisló de frutos de limón mexicano del estado de Colima, Méx. Cada concentración (1 x 105, 3 x 105, 5 x 105, 7 x 105, 9 x 105, 1 x 106 esporas mL-1), se colocó en heridas de 2 mm profundidad x 1mm de ancho, aproximadamente, hechas en frutos en etapa de madurez de corte. Las concentraciones 1 x 105 y 3 x 105 esporas mL-1 mostraron una incidencia de 33 y 50 % de infección, respectivamente, mientras que los frutos inoculados con 5 x 105, 7 x 105, 9 x 105 y 1 x 106 esporas mL-1 presentaron 100% de incidencia de la enfermedad. Asimismo, se... |

| Avaliou-se, de três a quatro anos de idade, as concentrações de clorofila a, clorofila b clorofila total e, a relação clorofila a/b de quatro diferentes procedências de grevílea (Grevillea robusta Cunn.), nos períodos de verão e inverno, plantadas na Região de Nova Esperança. Os resultados possibilitaram as seguintes conclusões: 1) em média, a grevílea na região de Nova Esperança, apresentou concentrações 30,42% mais elevadas de clorofila a em relação a clorofila b, no verão e concentrações 24,07% mais elevadas de clorofila a em relação a clorofila b, no inverno. 2) em média, a grevílea na região de Nova Esperança, apresentou concentração de 27,34% mais elevada de clorofila total, no verão, quando comparada com o inverno. 3) As procedências australianas... |

| Exopolysaccharides (EPS) from cell-free Porphyridium cruentum media were concentrated then purified (diafiltration) on a 0.14 µm ceramic membrane. The influence of cross-flow velocities on filtration performances was investigated. Mean permeate fluxes equal to 49.8, 68.9 and 81.9 L.h-1. m-2 were obtained during the concentration at 4 bar for respectively cross-flow velocities inside the membrane lumen equal to 2.5, 3.3 and 4.2 m.s-1; 49.7 L.h-1. m-2 for the diafiltration at 3.3 m.s-1. Permeate fluxes were correctly predicted from polysaccharide concentrations (10 % deviation). Volume reduction factors higher than 7.8 were reached. Rejection rates of polysaccharides and proteins varied according to the cross-flow velocities. Thus, the EPS recovery rate or... |

| Potential ways to address the issues that relate to the techniques for analyzing food and environmental samples for the presence of enteric viruses are discussed. It is not the authors' remit to produce or recommend standard or reference methods but to address specific issues in the analytical procedures. Foods of primary importance are bivalve molluscs, particularly, oysters, clams, and mussels; salad crops such as lettuce, green onions and other greens; and soft fruits such as raspberries and strawberries. All types of water, not only drinking water but also recreational water (fresh, marine, and swimming pool), river water (irrigation water), raw and treated sewage are potential vehicles for virus transmission. Well over 100 different enteric viruses... |
