CHEMICAL CONTAMINATION OF BEE HONEY – IDENTIFYING SENSOR OF THE ENVIRONMENT POLLUTION

Changes in the quality of bee honey are also caused by the contamination with micro-polluting agents, toxic to consumers. This research is about chemical contamination of honey. The honey used in this study was harvested from beehives situated in Copşa Mica (Sibiu region), famous for the ecological unbalances induced by the non-ferrous metal industry through pollution produced by SC Sometra SA. The amount of Pb, Cd and Zn contained in the samples harvested in the area specifi ed above have been determined using an atomic absorption spectrometer AAS. Amounts of heavy metals above the admitted limit by the OMS 975/88 have been discovered. The results suggested that honey could be used to detect contaminating agents from the environment

The Management of Manufacturing-Oriented Informatics Systems Using Efficient and Flexible Architectures

Industry and in particular the manufacturing-oriented sector has always been researched and innovated as a result of technological progress, diversification and differentiation among consumers' demands. A company that provides to its customers products matching perfectly their demands at competitive prices has a great advantage over its competitors. Manufacturing-oriented information systems are becoming more flexible and configurable and they require integration with the entire organization. This can be done using efficient software architectures that will allow the coexistence between commercial solutions and open source components while sharing computing resources organized in grid infrastructures and under the governance of powerful management tools.Manufacturing-Oriented Informatics Systems, Open Source, Software Architectures, Grid Computing, Web-Based Management Systems

Essential oil/alginate microcapsules; obtaining and applying

Introduction: Nowadays, plant extracts are highly applied in food industries either as sources of bioactive components or as an alternative to artificial additives. Therefore, food manufacturers are focused on innovative products, which can satisfy consumers' requirements. Objectives: This study investigates the encapsulation of Origanum majorana, Achillea millefolium, Foeniculum vulgare, Juniperus communis and Anethum graveolens EOs in alginate capsules as a means of controlling the fast release of volatile constituents. Materials and Methods: The EOs were obtained via steam distillation. Sodium alginate was chosen as a carrier because of its biodegradable and biocompatible properties. The paper describes the simple dripping technique used for the preparation of the alginate microcapsules with EO cores, and a possible application of the microcapsules as a natural flavor additive. Results: Sensorial properties of the final product were subjectively analyzed and described. The changes of the taste and the flavour of candies in comparison with the control sample were significant. Nevertheless, the strong herbal odour was found as "uncommon in confectionary but pleasant. Conclusion: It has been investigated, that the sodium alginate encapsulated EOs have to be added as a final step of a recipe to save its antimicrobial and antioxidant potential. Further assays need to be performed to investigate the recipe, which includes the EO alginate microcapsules in order to get a high-quality final product that can be used for commercial purposes

Minerals and Total Polyphenolic Content of Some Vegetal Powders

The total polyphenolic content and minerals were determined for chia seeds, Psyllium husks and watermelon rind powder. The minerals content was performed by using the Inductively Coupled Plasma Optical Emissions Spectrometer and Atomic Absorption Spectrometer, technique FIAS-Furnace (for Se). The sample with the highest content of polyphenols was chia (2.69 mg GAE/g s.) followed by the watermelon rind powder. Reduced amounts of polyphenols were found in the Psyllium husks. Also, the total polyphenol concentration increased with the increase of the extraction time on the ultrasonic water bath. Minerals analysis indicated that powders obtained from chia seeds and watermelon rind contained large amounts of potassium, calcium, phosphorus and magnesium. The most abundant mineral in the Psyllium husks powder was found potassium, followed by calcium. In conclusion, these powders can be used as ingredients for functional food and food supplements production due to the high nutritional content and bioactive properties

Comparative analysis and antimicrobial action of some essential oils from plants

In this research, essential oils (EOs) were extracted through steaming from aerial parts of three plants: basil (Ocinum basilicum L.), peppermint (Mentha piperita L.) and oregano (Origanum vulgare L.) form Sibiu County, Romania. The GC-MS analysis indicated that eugenol and apiol were the major compounds in the basil EO. Timol, ɣ-terpinene, and p-cymene were the major compounds in the volatile oil extracted from oregano and menthol and methone the main components in the peppermint EO. In the first 48 h of analysis, basil EO inhibition action was the highest against Salmonella anatum (48%), followed by Aspergillus niger (26%), Bacillus cereus (21%) and Saccharomyces cerevisiae (15%); this action was maintained for 120 h for all samples. In the first 48 h, the peppermint EO showed the highest inhibition rate (50%) on B. cereus, followed by A. niger (45%), S. cerevisiae (20%) and no action against Salmonella; this action varied after 72h and 120 h by slightly increasing in case of B. cereus, strongly decreasing in case of A. niger and remaining constant in case of S. cerevisiae. Oregano EO showed a very small antimicrobial action, only on S. anatum (12%) and this action was maintained for 120 h

Milk and Dairy Products Labeling in Romania

The present communication contains research and experimental investigations regarding the labelling process of dairy products in tight relation with the national and European legislative requirements. Two methods have been used during the marketing research regarding the information present on the labels of alimentary products: the method based on documentation-observation and comparative analysis of data and information collected from the consume market in Sibiu. The method based on documentation and observation has been carried out using the observation sheet and contained the following analysis criteria: The name of the product, Country origin of the product (location of the producer). Synthesizing the results and the conclusions emerged as a result of the marketing research carried out with the purpose of contouring a labelling model of alimentary products, it can be stated that the dynamics of the alimentary products market in Romania is moderate and restrained by the economical and social factors and even by the still reduces promotion of a healthy alimentary education, with the complementary protection of human health and environment
