Physical And Chemical

Camelina sativa L is a cruciferous oilseed plant. This plant is cultivated as an oilseed crop mainly in Europe and in North America and over the past years the cultivation has arranged in our country. The analyzed oil is obtained from the seeds of Camelina sativa L, growing in Bornuur, Tuv province. The goal of this study was to determine the physical and chemical characteristics and fatty acids composition of Camelina sativa L seed oil cultivated in Mongolia. According to our analysis total lipid was determined 38.52 %, moisture 4.80 % and total mineral elements 4.02 %, respectively. Mineral elements in Camelina sativa L seeds contain calcium (0.56 %), phosphorous (1.22 %), potassium (1.39 %), magnesium (0.53 %) in dominated amounts; iron, zinc, manganese and copper in trace amounts. Eight nonessential amino acids in seeds of this plant with total amount of 75.9 % were identified; phenylalanine was detected in highest amount among the all identified amino acids, while lysine, tryptophan and arginine are followed. The following characteristics in Camelina sativa seeds oil were determined. The refractive index was 1.4774 at 20°C, the peroxide value of fresh oil was 0.03 meq H2O2 /kg, saponification value 185.8 mg KOH/g, iodine value 143.33 g J2 and acidic value 6.27 mg KOH /g. Carotenoid was determined as 16.77 mg %, by spectrometry in Camelina sativa seeds oil. The analysis of fatty acids composition showed that there are 12.5 % saturated and 87.5 % unsaturated fatty acids. In particular, oleic acid (C18:1) 14.0 %, linoleic acid (C18:2) 9.0 %, α-linolenic acid (C18:3) 10.5 % and gondoic acid (C20:1) 32.8 %, were composed the major part of unsaturated fatty acids.

Relevance. Modern turkey crosses have a genetically determined high growth rate. These farm birds are very sensitive to even minor fluctuations in their diet, are susceptible to a deficiency of amino acids, protein, mineral elements and vitamins, which can contribute to a decrease in their productivity, the development of pathological processes and diseases. The use of modern technologies and scientific achievements has made it possible to prepare a new product — modified zeolite. This natural mineral is already free of impurities and microbes, with open pore windows, has a high ability to selectively exchange, and is obtained by various methods of activating zeolite in industrial conditions. At the same time, Ulyanovsk specialists have mastered the technology of enriching modified zeolite with useful substances.Methods. The aim of the work was to study the effect on the body of turkeys and the level of their productivity of additives based on modified zeolite enriched with amino acids. The experiment was organized for 60 days on 250 turkeys of the breed Hybrid Cread-mayker aged 55–60 days in the conditions of the Ulyanovsk region. The control group received the main ration (MR), the experimental group was given once a day in addition to the MR in the morning feeding in a mixture with mixed feed 5% additives of modified zeolite enriched with amino acids.Results. The inclusion of a supplement based on modified zeolite enriched with amino acids in the diet of turkeys does not have a negative effect on the hematological parameters of their blood, all indicators corresponded to the physiological norm. During the experiment in the 2nd group, the live weight of poultry was obtained larger by 8.70%, which amounted to 12,296 kg, respectively, more profit was obtained from the sale of turkey meat, total revenue was 133,210, and additional profit was 27,960 rubles, 2.41 rubles of profit was received for 1 ruble of costs. Тhe data indicate the normalization of mineral homeostasis in the body of turkeys and better absorption of nutrients in the feed diet.

Four strains of C. perfringens, including one classical-type strain and three strains recovered from presumably peccant food were analyzed for the content of selected amino acids and mineral elements. Suspensions of both vegetative cells and vegetative cell – spore mixtures were examined. Any differences observed could be correlated neither with the origin of the strain, the heat resistance, nor the α toxin production.

Background Place of origin is an important factor when determining the quality and authenticity of Angelica sinensis for medicinal use. It is important to trace the origin and confirm the regional characteristics of medicinal products for sustainable industrial development. Effectively tracing and confirming the material’s origin may be accomplished by detecting stable isotopes and mineral elements. Methods We studied 25 A. sinensis samples collected from three main producing areas (Linxia, Gannan, and Dingxi) in southeastern Gansu Province, China, to better identify its origin. We used inductively coupled plasma mass spectrometry (ICP-MS) and stable isotope ratio mass spectrometry (IRMS) to determine eight mineral elements (K, Mg, Ca, Zn, Cu, Mn, Cr, Al) and three stable isotopes (δ13C, δ15N, δ18O). Principal component analysis (PCA), partial least square discriminant analysis (PLS-DA) and linear discriminant analysis (LDA) were used to verify the validity of its geographical origin. Results K, Ca/Al, δ13C, δ15N and δ18O are important elements to distinguish A. sinensis sampled from Linxia, Gannan and Dingxi. We used an unsupervised PCA model to determine the dimensionality reduction of mineral elements and stable isotopes, which could distinguish the A. sinensis from Linxia. However, it could not easily distinguish A. sinensis sampled from Gannan and Dingxi. The supervised PLS-DA and LDA models could effectively distinguish samples taken from all three regions and perform cross-validation. The cross-validation accuracy of PLS-DA using mineral elements and stable isotopes was 84%, which was higher than LDA using mineral elements and stable isotopes. Conclusions The PLS-DA and LDA models provide a theoretical basis for tracing the origin of A. sinensis in three regions (Linxia, Gannan and Dingxi). This is significant for protecting consumers’ health, rights and interests.

A hydroponic experiment was carried out to determine influences of partial replacement of nitrate by ammonium and 20 amino acids of alanine (Ala), valine (Val), leucine (Leu), isoleucine (Ile), proline (Pro), phenylalanine (Phe), tryptophane (Trp), methionine (Met), aspartic acid (Asp), glutamic acid (Glu), lysine (Lys), arginine (Arg), histidine (His), glycine (Gly), serine (Ser), threonine (Thr), cysteine (Cys), tyrosine (Tyr), asparagines (Asn) and glutamine (Gln) on growths and concentrations of mineral elements of pakchoi (Brassica chinensis L.). Most of amino acids inhibit shoot growths of pakchoi. Different amino acids have various effects on concentrations of calcium (Ca), manganese (Mn), magnesium (Mg), iron (Fe), copper (Cu) and zinc (Zn) in shoots of pakchoi. There are differences in shoot fresh weights, dry weights and concentrations of mineral elements of pakchoi supplied with amino acids and ammonium.

Origin Identification

This study aimed to construct objective and accurate geographical discriminant models for tea leaves based on multielement concentrations in combination with chemometrics tools. Forty mineral elements in 87 tea samples from three growing regions in Guizhou Province (China), namely Meitan and Fenggang (MTFG), Anshun (AS) and Leishan (LS) were analyzed. Chemometrics evaluations were conducted using a one-way analysis of variance (ANOVA), principal component analysis (PCA), linear discriminant analysis (LDA), and orthogonal partial least squares discriminant analysis (OPLS-DA). The results showed that the concentrations of the 28 elements were significantly different among the three regions (p < 0.05). The correct classification rates for the 87 tea samples were 98.9% for LDA and 100% for OPLS-DA. The variable importance in the projection (VIP) values ranged between 1.01–1.73 for 11 elements (Sb, Pb, K, As, S, Bi, U, P, Ca, Na, and Cr), which can be used as important indicators for geographical origin identification of tea samples. In conclusion, multielement analysis coupled with chemometrics can be useful for geographical origin identification of tea leaves.
