The objective of this research was to develop Mucuna pruriens jelly formula to be suitable and easily edible for Parkinson’s patients. The recipe of jelly consisted of M. pruriens seed dry extract as an active ingredient, gelatin, glycerin, citric acid, sodium benzoate, steviol, coffee flavor, and purified water. The jelly was analyzed for physical and chemical characteristics by microscopy and UV-Vis spectrophotometry. It was found that pH of the M. pruriens jelly was 4.77. The microscopic characteristics showed that the jelly texture had a consistent distribution of various components (2.53 particles/cm2), with different particles sizes. The observation of the physical macroscopic characteristics found that M. pruriens jelly had dark brown color, smooth surface, and elastic texture, hence suitable for consumption. The analysis of physical stability by observing the changes of appearance with naked eyes for 4 weeks at 30 °C and 4 °C showed that M. pruriens jelly had physical stability at 4 °C better than at 30 °C. The chemical analysis of L-dopa by UV-Vis spectrophotometry revealed that M. pruriens jelly contained a sufficient amount of L-dopa i.e. 542 mg/piece. This research could be developed to be a health product for Parkinson’s patients by taking 2 pieces per day in the morning since the therapeutic dose for Parkinson’s disease is 1000 mg of L-dopa total/day (single dose in the morning).

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.

The production of lyophilized foods is a market with great growth potential, for providing important preservation characteristics, such as stability at ambient temperature, versatility of the product and preservation of the chemical compounds. Given the functional effects of peanut powder extracts, this study aimed to quantify the bioactive compounds and determine physical and chemical characteristics, comparing samples with and without skin. After obtaining the aqueous peanut extract the samples were frozen at -18 °C for 24 h. The formulated extracts were dried in a benchtop lyophilizer operating at temperature of -55 °C for a period of 48 hours. The powder extracts were disintegrated in a multiprocessor for 30 seconds and the samples were physically and chemically evaluated. The powder extracts were classified as non-hygroscopic, exhibiting poor fluidity and intermediate cohesiveness in samples with skin, and high cohesiveness in samples without skin. The powders showed agglomerated particles, with irregular and non-uniform shape. Potassium was the mineral found in largest amounts, as well as oleic and linoleic fatty acids. The particles of the powders exhibit a spherical shape, showing the presence of amorphous surfaces, in which there is no repetition of geometric forms. The peanut powder extracts are classified as non-hygroscopic, have poor fluidity, intermediate cohesiveness in samples with skin and high cohesiveness in samples without skin.

The mangabeira (Hancornia speciosa G.) is a native Brazilian species in the process of domestication. It has several potential uses. In recent years the populations of mangabeira have become fragmented and, to conserve their genetic resources, Embrapa Tabuleiros Costeiros has, since 2006, maintained a Mangaba Genebank, which currently has 299 individuals distributed across 27 accessions. In one of these accessions (CP), first fruiting was observed to occur at 13 months, indicating precocity. The current project was developed with the intention of morphologically characterizing the CP accessions and evaluating the extent of genetic diversity between genotypes, based on genetic markers associated with fruiting precocity. Morphological variation in crown and leaf shape, growth habit, total height, stem diameter and canopy height were investigated. For molecular characterization, 18 CP accession genotypes were used, all from Sergipe State, Brazil, and 11 ISSR markers were studied that generated 62 fragments with 91.4% polymorphism. The fruits have physical and chemical characteristics suitable for in natura consumption and also for processing. UPGMA dendrogram analysis showed the genotypes CP2 and CP6 to be most similar and CP10 the most divergent within the CP accessions. The results showed the existence of polymorphism, and genetic divergence among genotypes, thus reinforcing the importance of constant germplasm characterization, which guarantees information on gene sources for future use, while providing information concerning potential parents that can be used in breeding programs as well as the identification of duplicates.

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.

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 aim of this work was to verify the influence of drying on physical and chemical characteristics of residues from rice milk production. Residues were from the production of white, red and black rice. They were dehydrated in an oven with air circulation at 60ºC for 8h. Characterization of them were carried out by physical and chemical analyses. Residues have presented statistical difference for all parameters measured. Its characterization is necessary to justify its use in other process or application on new products.The residues from rice milk production have high content of nutrients and phenolic compounds, even after dehydration. Keywords: Nutrients; Oryza sativa; waste.

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.
