CFP may be a prebiotic due to its high resistance against α-amylase and acid. CFP provides two ways to adjust nitric oxide synthesis in macrophages. We show the use of CFP in the production of synbiotic yogurt with favorable physical and chemical characteristics.

The purpose of this study was to characterize 26 banana accessions of the active genebank of Embrapa Cassava and Tropical Fruits (Brazil) for agronomic, physical and physicochemical characteristics. The plant height of the diploid 028003-01 and triploid Walha was short. Regarding the number of fruits and bunch weight, the triploids Caipira, Thap Maeo and the tetraploids Ambrósia and Calipso performed particularly well. Total carotenoid contents were highest in the diploids Jaran and Malbut. The total contents of flavonoid and polyphenol, two natural antioxidants, were highest in tetraploid Teparod. Wide genetic variability was detected for most agronomic, physical and chemical characteristics of the fruits of the banana accessions, enabling the planning of breeding for the development of hybrids with short stature, high yield, pest resistance and high carotenoid, flavonoid and/or polyphenol contents.

There are few information on the physical and chemical characteristics of peach fruit in subtropical climate regions and the majority of the studies were developed in the southern region of Brazil. In this study, physical and chemical characteristics of 12 white-fleshed peach cultivars (Cristal, Cristal Tacoari, Colibri, Delicioso Precoce, Jóia 1, Jóia 2, Jóia 4, Marli, Okinawa, Pérola de Itaquera, Premier and Tropical) were evaluated. The cultivars were planted in the experimental orchard of the Federal University of Viçosa (UFV), Viçosa – MG, Brazil. The experiment was conducted during the 2011 harvest season, in a completely randomized design with 12 treatments (cultivars), three replications and 10 fruits per plot. The cultivars Delicioso Precoce and Marli showed, in general, higher mass and fruit diameter. Fruits of cultivars Jóia 2 and Tropical presented higher firmness. Cultivar Tropical stood out with better balance between acidity and soluble solids and higher vitamin C and carotenoids contents.

Silver halide grains (AgX, X=Cl,Br,I) are commonly recognized as important entities in photographic applications. Depending on the preparation specifications one can grow cubic, octahedral, tabular a.o. morphologies, each with its own physical and chemical characteristics. In the present study crystallographic defects introduced by the mixing of 5-20% iodide in a growing AgBr tabular grain are investigated. X-ray diffractometry reveals the existence of a homogeneous Ag(Br1-xIx) region, expected to be formed around the AgBr kernel. In fig. 1 a two-beam BF image, taken at T≈100 K to diminish radiation damage, of a triangular tabular grain is presented, clearly showing defect contrast fringes along four of the six directions; the remaining two sides show similar contrast under relevant diffraction conditions. The width of the central defect free region corresponds with the pure AgBr kernel grown before the mixing with I. The thickness of a given grain lies between 0.15 and 0.3 μm: as indicated in fig. 2 triangular (resp. hexagonal) grains exhibit an uneven (resp. even) number of twin interfaces (i.e., between + and - twin variants) parallel with the (111) surfaces. The thickness of the grains and the existence of the twin variants was confirmed from CTEM images of perpendicular cuts.
