An experimental field for the cultivated production of Gentiana lutea L. was established five years ago at the Suvobor Mountain, Serbia. Soil analysis of this area revealed the occurrence of high pseudo-total (Ni - 1270 mg/kg, Cr - 423 mg/kg, Co - 385 mg/kg) and available (especially Ni - 133 mg/kg) heavy metals contents in the soil. Hence, the aim of this research was to evaluate the quality of Gentiana lutea L. - roots and galenic forms (liquid extract in 70 % ethanol, spissum and siccum) produced from the roots, because, for most plants, heavy metals accumulate in the root tissue. The amounts of Ni and Cr found in the analyzed roots were very high (54 mg/kg and 14 mg/kg, respectively). The efficiency of ethanol in extracting heavy metals from the roots varied depending on the particular element. The highest efficiency was obtained for Ni (41.3 %), then for Cd (39.5 %), Pb (37.0%) and Co (30.4 %). According to this, a potential hazard exists for humans, if gentian's galenic forms are produced from the raw material with high heavy metals contents. It is concluded that quality control of the raw material must be carried out before further utilization of gentian. .

<p>The analysis of samples by using spectroscopic fingerprinting techniques is more and more common and widespread. Such approaches are very convenient, since they are usually fast, cheap and non-destructive. In many applications no sample pretreatment is required, the acquisition of the spectrum can be performed in about one minute and no solvents are required. As a consequence, the return on investment of the related technology is very high.<br />The "disadvantage" of these techniques is that, being the signal non-selective, simple mathematical approaches (e.g., Lambert-Beer law) cannot be applied. Instead, a multivariate treatment must be performed by using chemometrics tools.<br />In what concerns food analysis, they can be applied in several steps, from the evaluation of the quality and the conformity of raw material to the assessment of the quality of the final product, to the monitoring of the shelf life of the product itself. Another interesting field of application is the verification of food-authenticity claims, this being extremely important in the case of foods labeled as protected designation of origin (PDO), protected geographical indication (PGI) and traditional speciality guaranteed (TSG).<br />In the present paper, it is described how non-selective signals can be used for obtaining useful information about a food.</p>

Abstract Cyanthillium cinereum (L.) H.Rob. is one of the most popular herbal smoking cessation aids currently used in Thailand, and its adulteration with Emilia sonchifolia (L.) DC. is often found in the herbal market. Therefore, the quality of the raw material must be considered. This work aimed to integrate macro- and microscopic, chemical and genetic authentication strategies to differentiate C. cinereum raw material from its adulterant. Different morphological features between C. cinereum and E. sonchifolia were simply recognized at the leaf base. For microscopic characteristics, trichome and pappus features were different between the two plants. HPTLC profiles showed a distinct band that could be used to unambiguously differentiate C. cinereum from E. sonchifolia. Four triterpenoid compounds, β-amyrin, taraxasterol, lupeol, and betulin, were identified from the distinct HPTLC band of C. cinereum. The use of core DNA barcode regions; rbcL, matK, ITS and psbA-trnH provided species-level resolution to differentiate the two plants. Taken together, the integration of macroscopic and microscopic characterization, phytochemical analysis by HPTLC and DNA barcoding distinguished C. cinereum from E. sonchifolia. The signatures of C. cinereum obtained here can help manufacturers to increase the quality control of C. cinereum raw material in commercialized smoking cessation products.

Microbiological quality of laver, one of the edible seaweeds, has not been reported in a real processing line. Laver or supplements were collected from six manufacturers (A to F) to assess potential microbiological hazards and the critical control points in commercial processing lines. Aerobic plate counts (APC), coliform counts, Bacillus cereus, Staphylococcus aureus, and Vibrio parahaemolyticus were enumerated, and the presence of B. cereus, Listeria monocytogenes, Salmonella, S. aureus, and V. parahaemolyticus were confirmed during processing. The raw material, i.e., dried laver, had a high initial APC level (4.4 to 7.8 log CFU/g), which decreased gradually during processing (final products, 1.3 to 5.9 log CFU/g). Coliforms and B. cereus were not detected in any of the final products, but they were present in some raw materials and semiprocessed products in quantitative analysis. After enrichment for recovery of stress-injured cells, E. coli and foodborne pathogens were not detected in any samples, with the exception of B. cereus. Heat-injured and spore-forming B. cereus isolates were occasionally obtained from some of the raw materials and products after enrichment, thus B. cereus may be a potential microbiological hazard that should be controlled using strategic intervention measures. Secondary roasting (260 to 400°C, 2 to 10 s) significantly reduced the APC (maximum log reduction, 4.7 log CFU/g), and this could be a key intervention step for controlling microbiological hazards during processing (critical control point). When this step was performed appropriately, according to the processing guide for each plant, the microorganisms were inactivated more successfully in the products. This study provides scientific evidence that may facilitate the development of strategies for microbiological hazard control and hygienic management guidelines for real manufacturing plants.

<p>The artisan cheese production is an important income source for family farmers, however the lack of standardization and negligence in the preparation of the product generates a low quality cheese. The production of cheese of good quality finds some obstacles, because milk does not contribute in many ways to ensure the characteristics of the product. The aim of this study was to evaluate the physico-chemical characteristics of 20 Minas Frescal cheeses, of which 10 samples were artisanal and 10 have industrial production. The handmade cheeses were sold in street markets and all the samples had no labeling and sanitary inspection seal. The industrialized were obtained in supermarkets, all the 20 samples were acquired in Londrina-PR. The analyses performed were &nbsp;moisture, fat (d.b.), pH and acidity. The fat analysis showed that 50% of samples from artisanal cheeses and 40% of industrialized ones violate the current laws. The pH of artisanal cheese samples ranged between 5.2 and 6.7 and the acidity ranged between 0.06 and 2.41%. The variation in acidity showed that the cheeses are made without standard and quality control of raw material. In industrialized cheeses the pH ranged between 5.3 and 6.5 and acidity between 0.2 and 1.4%. With this work we concluded that the small producers and industries do not pay attention to physico-chemical parameters essential to the quality of the cheese.</p><p>&nbsp;</p><p>DOI: http://dx.doi.org/10.14685/rebrapa.v2i2.48</p>

The article is devoted to the possibilities of application of artificial neural networks (ANN), which are a mathematical model, as well as its software or hardware implementation, built on the principle of organization and functioning of nerve cell networks of a living organism. Convolutional neural networks are arranged like the visual cortex of the brain and have achieved great success in image recognition, they are able to concentrate on a small area and highlight important features in it. The widespread use of ANN in medicine for the evaluation of radiographs, blood pressure and body mass index of patients on the analysis of their retina is noted. The use of ANN in the food industry for input quality control of raw materials is promising. In the world practice, various methods of remote control of raw materials are used, for this purpose ultrasonic scanning devices are mainly used. Such devices and analysis systems control raw materials by the ratio of meat tissues (muscle, connective, fat) in the carcass or half-carcass, without affecting the tissue structure, do not lead the quality at the cellular (microstructural) level. It is established that the structure of muscle (diameter of muscle fibers, the safety of the cellular elements, the porosity of the tissue, integrity of muscle fibers) reflects the quality of the raw material, its thermal state. Our work has begun on the creation of an expert system for quality control of meat raw materials at the microstructural level using modern intelligent technologies as ANN and computer vision. This direction is relevant and socially significant in the development of the meat industry, as it will significantly speed up the process of analysis of the quality of raw meat in the research laboratories of meat processing enterprises and testing centers and improve the objectivity of the results.

Quality Of Irrigation Water

Abstract The quality of untreated water used by dry season vegetable growers determines the safety of the vegetables produced for human consumption. Traditionally, small scale vegetable farmers site their farms along banks of streams which gradually dry up during the dry season resulting in isolated pockets of ponds at different intervals along the path of the streams which are used by farmers to irrigate. A field experiment was initiated at Ibadan to ascertain the quality of irrigation water used to produce vegetables along Ona-stream during the dry season. Five isolated ponds and one locally dug well were sampled and analysed to ascertain the heavy metals status. Results of soil analysis from five farms (A - E) sited very close to the stream revealed high concentrations of heavy metals ranging from 0.96 to 2.34 mg kg-1 for Pb, 0.72 to 2.16 mg kg-1 for Cr and 0.30 to 0.92 mg kg-1 for Co while farmland F sited about 90m away from the stream was free of Pb, Cr and Co contaminants. Locally dug well F water was free of Cr, Co and Pb while isolated ponds had Cr, Co and Pb in the range of 0.01 to 0.23 mg kg-1 which is beyond safe consumption thresholds. There were strong correlations between heavy metals in water and vegetable for Cr (0.992**), Cd (0.599**), Ni (0.614*) and Pb (0.552**) indicating that the hygienic status of dry season vegetables is largely determined by the quality of irrigation water. In addition, all vegetables irrigated with untreated isolated ponds contained Cd, Pb and Ni concentrations above maximum permissible standard which could pose risk to human health. Therefore, farmers should be enlightened on the need to use hygienic water for irrigation. Construction of shallow wells on the farms instead of using contaminated stream water directly could be a better option for healthy and sustainable agriculture.

A study was undertaken to evaluate the status of organic matter, mineral nutrients and heavy metals content in seven differentsoils from fourteen selected regions of Bangladesh. The location were BAU farm, Sutiakhali, Ishardi, Lalpur, Dumuria,Kotalipara, Asasuni, Chorfasion, Kaligonj, Botiaghata, Madhupur, Tangail sadar, Chakaria and Moheskhali. Forty two surfacesoils (0-15 cm depth) were collected from 14 regions (3 samples from each region) of Bangladesh during November-December,2009. The results obtained from this study showed that the organic matter of these soils very low to very high (0.65% inMadhupur to 28.24% in Dumuria) and the total N content of soil followed the same trend of organic matter ranging 0.056 to1.638% in Madhupur and Dumuria region, respectively. The available P and S in the top of soils ranged from 3.77 ?g g-1 in Moheskhali to 17.28 ?g g-1 in BAU farm and 13.40 ?g g-1 in Madhupur to 420.32 ?g g-1 in Moheskhali, respectively. In the contextof micro nutrients, the maximum available Zn, Cu, Fe and Mn were found 6.43 ?g g-1 in Dumuria, 8.06 ?g g-1 in Chakaria, 346.12?g g-1 in Madhupur and 83.5 ?g g-1 in Madhupur, respectively. whereas the lowest amount of these micronutrients were found 1.22?g g-1 in Botiaghata, 0.2 ?g g-1 in Dumuria, 7.62 ?g g-1 in Ishardi and 2.39 ?g g-1 in Lalpur, respectively. Possible contamination ofthe studied soils by heavy metals was not significantly observed. The OM, total N and other nutrients were found to be the dominantfactors influencing not only the availability of macro and micro nutrients and heavy metals but also the quality of soil.DOI: http://dx.doi.org/10.3329/jesnr.v5i2.14570 J.
