Abstract. The purpose of the performed researche was to establish the quality of some meat products in casings belonging to the semi-smoked group obtained in a meat processing factory. In this respect, organoleptic and physical-chemical analysis have been performed on ten assortments belonging to the specified group of the meat products in casings. The obtained results highlight that, from organoleptic point of view the finished products are in compliance with the standard provisions excepting some assortments in which case were found some physical faults such as: wrinkled casings (in case of the Italian and pork salamis), the presence of conjunctive tissue on section (in case of the Victoria salami) or pork skin improperly minced (the Salajeni sausages), exuding fat at the ends of the bar-salamis (in case of the Crakauer salami), air holes under the casing (in case of the Trandafir sausages) or on section (in case of the Vara salami). These physical faults are caused by the non-observance of some technological parameters. The incidence of these faults does not exceed 12.8% of the total number of analyzed samples. From physical-chemical point of view the obtained values for the finished products are in accordance with the in force quality standards, excepting 10% from the total number of analyzed samples (small exceedings of the maximum admitted limit of the moisture content in case of the Vara, Italian and pork salamis and the salt content for the Populari sausages). There have been analysed the causes of these faults and the necessary measures to prevent occurrence of these faults and insuring the quality of the finished products

This study was conducted to compare the technological properties of burger patties and emulsion sausages processed from imported Brazilian and Indian meat. Burger patties and emulsion sausage were processed from these meat and the processed products were analyzed for proximate chemical analysis, deterioration criteria, instrumental color, shear force, sensory attributes, cooking characteristics for burger patties, and emulsion stability for the emulsion sausage. The results revealed that using imported Brazilian chuck meat in processing of burger patties and emulsion sausage resulted in significant increase in L* values, moisture content, sensory attribute and significant decrease of a* values and shear force values and non-significant change of deterioration criteria. There were non-significant changes in cooking characteristics of the burger patties processed from imported Brazilian or Indian meat however; higher emulsion stability in emulsion sausage processed from imported Brazilian meat was observed. Therefore, Indian meat can be used in meat processing after Brazilian meat which may give chance to the producers to formulate good quality products from lower price meat source.

INTRODUCTIONThe prospect of performing chemical analysis of thin specimens at any desired level of resolution is particularly appealing to the materials scientist. Commercial TEM-based systems are now available which virtually provide this capability. The purpose of this contribution is to illustrate its application to problems which would have been intractable until recently, pointing out some current limitations.X-RAY ANALYSISIn an attempt to fabricate superconducting materials with high critical currents and temperature, thin Nb3Sn films have been prepared by electron beam vapor deposition [1]. Fine-grain size material is desirable which may be achieved by codeposition with small amounts of Al2O3 . Figure 1 shows the STEM microstructure, with large (∽ 200 Å dia) voids present at the grain boundaries. Higher quality TEM micrographs (e.g. fig. 2) reveal the presence of small voids within the grains which are absent in pure Nb3Sn prepared under identical conditions. The X-ray spectrum from large (∽ lμ dia) or small (∽100 Ǻ dia) areas within the grains indicates only small amounts of A1 (fig.3).

One aspect of enzyme cytochemistry is, whether all macrophage lysosomal hydrolytical enzymes are present in an active form, or are activated upon stimulation. Integrated morphometrical and chemical analysis has been chosen as a tool to illucidate that cytochemical problem. Mouse peritoneal resident macrophages have been used as a model for this complicated integration of morphometrical and element-related data. Only aldehyde-fixed cells were treated with three cytochemical reactions to detect different enzyme activities within one cell (for details see [1,2]). The enzyme-related precipitates anticipated to be differentiated, were:(1).lysosomal barium and sulphur from aryl sulphatase activity,(2).lysosomal cerium and phosphate from acid phosphatase activity and(3).platinum/di-amino-benzidine( D A B) complex from endogenous peroxidase activity.

Compositional Variations

BaFeO3-y compositions (0.35<y<0.50) have been investigated by means of electron diffraction and microscopy to resolve contradictory results from powder X-ray diffraction data.The samples were obtained by annealing BaFeO2.56 for 48 h. in the temperature range from 980°C to 1050°C . Total iron and barium in the samples were determined using chemical analysis and gravimetric methods, respectively.In the BaFeO3-y system, according to the electron diffraction and microscopy results, the nonstoichiometry is accommodated in different ways as a function of the composition (y):In the domain between BaFeO2.5+δBaFeO2.54, compositional variations are accommodated through the formation of microdomains. Fig. la shows the ED pattern of the BaFeO2.52 material along thezone axis. The corresponding electron micrograph is seen in Fig. 1b. Several domains corresponding to the monoclinic BaFeO2.50 phase, intergrow with domains of the orthorhombic phase. According to that, the ED pattern of Fig. 1a, can be interpreted as formed by the superposition of three types of diffraction maxima : Very strong spots corresponding to a cubic perovskite, a set of maxima due to the superposition of three domains of the monoclinic phase along [100]m and a series of maxima corresponding to three domains corresponding to the orthorhombic phase along the [100]o.
