The aim of this study was to investigate the effects of Ferulago angulata and Spirulina platensis extract at 0.1 to 1% (v/v) on the color parameters, survivability of starter cultures and Lactobacillus acidophilus and sensory characteristics in low–fat yogurt during 1, 7, 14 and 21 d. The results showed that by increasing the extract concentration, average values of b* and light intensity (L*) was declined and control, showed the highest lightness during storage. Treatments containing F. angulata extract had a higher a* and b* values and color intensity (C*) in compartion with S. platensis extract. The mean values of total color difference (∆E*) at the first week and last two weeks were higher in the treatments containing S. platensis and F. angulata, respectively. The mean L. bulgaricus count more than St. thermophilus and the mean count of starter cultures in the treatments containing S. platensis extract was significantly higher than F. angulata extract. However, the survivability of starter cultures and L. acidophilus at the end of the refrigerated storage was more than standardized number of bacteria (107–108cfu/ml) in yogurt. The color, flavor, consistency and overall acceptability scores of treatments containing S. platensis extract were significantly higher than the F. angulata extract. Therefore, these additives could be used successfully without having detrimental effects on bio–yogurt.

The combined effects of some chemicals on β–galactosidase activity by Anoxybacillus sp. FMB1 were studied using semiparametric errors in variables methodology when the error has an unknown distribution. An experimental design was chosen to explain six chemicals, dithiothreitol (DTT), phenylmethylsulfonyl fluoride (PMSF), N–ethylmaleimide (NEM), iodoacetamide (Iod A), –Mercaptoethanol (β–Mer) and 1,10–phenanthroline (phen) and to investigate the results. This technique constrained the number of real experiments performed while considering conceivable interactions between six chemicals. The optimal combinations of chemical concentration for maximum β–galactosidase activity was determined as 8 mM DTT, 8 mM PMSF, 8 mM NEM, 8 mM Iod A, 2 mM β–Mer and 2 mM phen. We also compared the no measurement error case and errors in variables case. The proposed estimator shown has better performances. Keyword: β–galactosidase, inhibition, semiparametric EIV Model, unknown distribution
在误差分布未知的情况下，采用半参数误差变量法研究了几种化学物质对Anoxybacillus sp. FMB1 β -半乳糖苷酶活性的综合影响。采用实验设计对二硫苏糖醇(DTT)、苯基甲基磺酰氟(PMSF)、n -乙基马来酰亚胺(NEM)、碘乙酰胺(Iod A)、-巯基乙醇(β-Mer)和1,10 -菲罗啉(phen) 6种化学物质进行了解释，并对结果进行了研究。这种技术限制了实际实验的数量，同时考虑到六种化学物质之间可能的相互作用。确定β -半乳糖苷酶活性最高的最佳化学浓度组合为8 mM DTT、8 mM PMSF、8 mM NEM、8 mM Iod A、2 mM β-Mer和2 mM phen。我们还比较了无测量误差情况和有变量误差情况。所提出的估计器具有较好的性能。关键词:β -半乳糖苷酶，抑制作用，半参数EIV模型，未知分布

Seed size, seed shape and seed colour are easily discernible phenotypic traits of beans in the market. Consumers often have specific preferences to different combinations of seed size, shape and colour. Local landraces are usually grown for their desired organoleptic and seed properties by consumers. This study investigated the variability in seed size attributes, seed shape, visual seed colour properties and seed luminosity/chromaticity properties of the germplasm of 255 landraces representing major local bean types grown in 20 provinces in Western Anatolia Region of Turkey. Measurements were made on seeds from representative single plants for seed size index, 100 seed weight, seed length, seed width, seed thickness, seed width in cross section, seed shape, seed degree of curvature in kidney types, seed shape in cross section, number of seed colors, main seed color, secondary seed colour, distribution of secondary seed color, seed veining, colour of hilum ring and values of L (Luminosity), chromaticity a*, chromaticity b*, chroma (C) and hue angle. Data were statistically analysed, principle component analysis was carried out, the germplasm was classified by UPGMA dendograms and selections were made on the bases of GGE biplot analysis. Landraces showed a considerable diversity for seed size, seed shape and seed colour trait measured. All seed size variables ranged by 2–10–fold within the germplasm. 100–seed weight ranged ten–fold from very small seeded Meso–American types (18.4 g, e.g. AYD–8, KTH–30, MGL–1, DNZ–1 and BRD–24) to very large seeded Andean types (182.3 g, e.g. MGL–37, PKS–1, ANT–33, MGL–31 and ANT–16). Seed shape also varied as kidney–shaped (96 landraces), circular to elliptic (73), circular (58), elliptic (27) and rectangular (1) shapes. Main and secondary seed colours had considerable variation within the germplasm with 151 landraces had white, 31 grey, 31 beige, 23 brown, 8 violet, 5 red and 4 black main seed colour whereas 24 landraces had violet followed by 17 black and 14 red secondary seed colour. Landraces exhibited a large variation for chromaticity and luminosity variables. L value ranged between 20.3 and 90.1 representing a 4.5–fold variation. The landraces in the germplasm were assessed and characterised on the bases of diversity in seed morphological traits. Selections were made using UPGMA dendogram and GGE–biplot for production and breeding bean cultivars for preferences of changing consumer demands. Keyword: Beans, seed size, seed shape, seed colour, luminosity, chromaticity.

The onion sweet bulb genotypes grown in the Crimean republic (Russia) have a high nutritional value, but have been poorly characterized so far. Research was carried out in order to assess quality, antioxidant and mineral composition features of 9 Crimean genotypes in comparison with the Italian sweet variety ‘Tropea’. ‘Yaltinsky 6А’ showed the highest yield. Beam Promine attained the highest values of bulb dry residue, soluble solids and total sugars, but the lowest monosaccharides content. The Crimean genotypes showed higher levels of ascorbic acid and total acidity than ‘Tropea’, but lower concentrations of Fe, Cu, Mn and Zn. The Crimean genotypes examined showed interesting yield and quality performances, and also the potentiality to valorizing the bulb peel for extracting health–beneficial compounds such as antioxidants.

The concentration of heavy metals in the meat was analysed in seven geographical areas in Romania. The concentrations of heavy metals in the meat was determined with spectrophotometric method. In the present study, the higher heavy metals concentration was found in Mures, Satu–Mare and Salaj areas, while the lower concentration was observed in Brasov and Bistriţa–Nasaud areas. The geographical areas considered in this study are the most polluted areas of Romania and have the highest heavy metals concentration in meat.
