At this juncture, more and more attention is drawn to the preservation of the gene pool of local breeds of poultry, which have a set of valuable features, including high-quality eggs. In this study, the quality parameters of eggs (egg weight, weight, and proportion of yolk, weight, and proportion of albumen, yolk-albumen ratio, energy value, lipid and fatty acid content in the yolk) of chickens of Ukrainian selection(such hybrids as Plymouth white, Poltava Clay, Birkivska Barvysta and their interbreed hybrids) and foreign commercial crosses (Tetra SL, Tetra H, Super Harko, Lohmann Brown, Highsex White and Brown, High Line W36), at different ages (26, 34, 44 weeks of age) were studied in the comparative aspect. The average egg weight of Ukrainian breeds and hybrids was 51.9 g, 56.5 g, and 61.2 g at the age of 26, 34, and 44 weeks, respectively, in foreign crosses it was much higher - 59 g, 61.2 g, and 64.5 g, respectively (p <0.01). At the same time, there was a probable advantage of the Ukrainian selection bird over the foreign selection bird in the proportion of yolk (by 4.3%, 2.9%, and 4.1% at the age of 26.34 and 44 weeks, respectively), the yolk-albumen ratio (by 0.12, 0.07 and 0.08, respectively) and the energy value of the egg (76, 48 and 60 kJ, respectively). Higher lipid content was found in the egg yolks of domestic chickens in comparison with the foreign hybrid Tetra SL. The total content of saturated and unsaturated fatty acids in the egg yolks in hens of local breeds is higher than in foreign cross. High-quality characteristics of eggs of local breeds and populations are evidence of the presence of a valuable set of genes that require comprehensive study, preservation, and use in the creation of new selectively significant forms.

<p>Three wild populations of crucifix crab<em> Charybdis feriatus</em> were sampled and muscle was analyzed for proximate composition, amino acid and fatty acid composition, aimed to quantify and compare the nutritional quality from three different locations in China. Results showed that crude protein content in muscle of female crucifix crab<em> C. feriatus</em> from Zhoushan (ZS) and Xiapu (XP) (84.84%-88.35%) were significantly higher than that of crucifix crab<em> C. feriatus</em> from Qionghai (QH) (74.33%), while there was no significant difference in terms of crude fat content (3.82%-4.07%). The highest content of ash was found in muscle of crucifix crab<em> C. feriatus</em> from QH (5.36%). The muscle of crucifix crab<em> C. feriatus</em> from ZS and XP had significantly higher contents of total amino acids, essential amino acids, non-essential amino acids and delicious amino acids than those of QH group (<em>P </em>&lt; 0.05). The total saturated and unsaturated fatty acid content in the muscle of crucifix crab<em> C. feriatus </em>from three wild populations showed significant difference (<em>P </em>&lt; 0.05). The ZS group had highest content of poly-unsaturated fatty acids (33.64%) and total content of EPA and DHA (22.85%) as well, followed by XP and QH group (<em>P </em>&lt; 0.05). Overall, the differences in chemical composition in muscle of <em>C. feriatus </em>from different locations<em> </em>could be attributed to environmental variables and maturation stage.</p>

Abstract The main goal of the rational use of bast fiber raw materials is to develop and apply optimal methods of its processing. Work on the creation of such technologies is carried out by leading scientists of the industry in accordance with three main areas of research: the search for ways to increase the yield of long flax fiber and improve its consumer properties by using various methods of ennobling; improving the methods to unfold bundles of technical fibers and obtain elementary bast fibers (cotonized fiber); and integrating the use of waste from primary processing of bast-fiber raw materials based on existing hydrolysis and thermal decomposition technologies. However, with some exceptions, the vast majority of research is limited to laboratory experiments, largely because the bast stem is a very complex composite. This raises a number of questions for researchers. In varieties and breeding samples with high fiber quality, the total fatty acid content is higher, and the ratio of total saturated acids to unsaturated acids is lower. A method for evaluating The selection material of the same flax based on fiber quality and lodging resistance is based on determining the total content of fatty acids and total lipids and the ratio of saturated to unsaturated fatty acids in flax stalks and seeds. Subsequent comparison of the obtained indicators of the studied selection material was according to the indicators of the standard variety.

The aim of this study was to assess the effects of four types of selenium (Se) feed supplements on the indicators of the oxidative stability of egg yolk. A total of 1,740 Bovans Brown laying hens were divided into 4 experimental and 1 control group. The diets fed to the experimental groups were supplemented with 0.2 mg/kg of Se, provided as sodium selenite, Se-enriched yeast, synthetic L-selenomethionine and hydroxy-analogue of selenomethionine. The highest concentrations of MDA, an indicator of secondary lipid oxidation, were confirmed in the Control Group eggs (P < 0.001). Egg yolks from the Control Group were found to have the highest lightness (P = 0.032), the lowest colour chroma and the lowest proportions of the red and yellow colours (P < 0.001). The highest vitelline membrane strength was measured in eggs from groups fed diets supplemented with organic Se (P < 0.001). No significant differences were found between groups in the total fatty acid content, the content of saturated and unsaturated fatty acids or the n-6/n-3 fatty acid ratios. Our study confirmed the effect of Se feed supplements on the concentration of MDA and the colour indicators of egg yolk and on the vitelline membrane strength.

The study was designed to investigate the chemical composition and the biological effects of G. parviflora and V. polyanthes ethanolic extracts in vitro. Total content of phenols, flavonoids and tannins was quantified by spectrophotometry; chemical characterization was permed by mass spectrometry (ESI (-) FT-ICR MS and APCI (+) FT-ICR MS analysis). Antioxidant activities were determined by FRAP and Fe2+ chelating methods. Extracts cytotoxicity was evaluated in human lymphocytes, sarcoma-180 (S-180) and human gastric adenocarcinoma (AGS) cells, by MTT assay. V. polyanthes presented higher total content of tannins and G. parviflora presented higher amount of phenols and flavonoids. Chemical characterization showed the presence of flavonoids, phenolic acids and sesquiterpene lactones in V. polyanthes extract, and steroids, phenolic acids and fatty acids (Poly Unsaturated Fatty Acids - PUFA) in G. parviflora extract. V. polyanthes extract stood out in the Fe2+ chelation test. G. parviflora extract did not present outstanding antioxidant results in the tested protocols. Both species showed a tendency to promote cytotoxicity in human lymphocyte cells. Regarding the antiproliferative effect, both species were able to reduce S-180 cell viability and G. parviflora extract showed high antiproliferative potential in the assay with AGS cells. These findings reinforce the medicinal use of these plants, as well as suggest their potential use for the development of new drugs and for the treatment of cancers.

The production technology of high-quality vodka used in Russia involves filtration through activated charcoal. To approach the quality of renowned Russian vodka, one prominent Czech spirit-producing company installed on its production premises a filtration device including a charcoal column, and launched test runs during which different filtration conditions were tested. Samples collected during the test runs were analysed by GC-FID and GC-MS with the aim to compare their composition; sensory analysis was an integral part of the evaluation. The results documented a positive effect of charcoal filtration on the quality of produced vodka, which was not reduced when higher flow rates were applied. &nbsp;

AbstractWe studied a sample of 146 Polish, exclusively breastfeeding mothers and their healthy born on time infants to explore the effect of perinatal psychosocial stress on breast milk composition. Maternal perinatal stress was assessed using Recent Life Changes Questionnaire summarizing stressful events from the previous six months. Stress reactivity was determined by administering the cold pressor test and measuring cortisol in saliva samples taken during the test. Breast milk sample was taken to measure energy, protein, fat, lactose, and fatty acid content. Analyses revealed that stress reactivity was positively associated with milk fat and long-chain unsaturated fatty acids and negatively associated with milk lactose. Perinatal psychosocial stress negatively affected energy density, fat as well as medium-chain and long-chain saturated fatty acids in milk. These results, together with previous studies, advocate monitoring maternal psychological status during the peripartum to promote breastfeeding and healthy infant nutrition.

The supplementation of rumen bypass fat (RBF) has remained one of the preferred approaches used to decrease undesirable saturated fatty acids (FA) and increase beneficial unsaturated FA in the meat. This study was planned to evaluate the influences of rumen bypass fats on meat quality, fatty acid and metabolic profiles in male Dorper sheep (n = 36) with 24.66 ± 0.76 kg (mean ± standard error) initial body weight. Treatment comprised a basal diet (30:70 rice straw to concentrate) with no added RBF as a control (CON), basal diet with prilled fat (PF), basal diet with prilled fat plus lecithin (PFL) and basal diet with calcium soap of palm fatty acids (CaS). The findings revealed that cooking loss, drip loss and shear force in longissimus dorsi (LD) muscle were not affected by RBF supplementation, while meat pH was significantly higher in the CaS on aging day 1. However, the diet supplemented with prilled fat and lecithin modified the meat’s fatty acid profile significantly by increasing unsaturated fatty acids and decreasing saturated fats. The relative quantification of the major differentiating metabolites found in LD muscle of sheep showed that total cholesterol, esterified cholesterol, choline, glycerophosphocholine and glycerophospholipids were significantly lower in CaS and PFL diets, while glycerol and sphingomyelin were significantly higher in CaS and PFL diets. Most of the metabolites in the liver did not show any significant difference. Based on our results, the supplementation of protected fats did not have a negative influence on meat quality and the meat from Dorper sheep fed prilled fat with lecithin contained more healthy fatty acids compared to other diets.

Olein Oil

Palm oil is the most abundant of all oils produced globally. It is very high in saturated fatty acids specifically palmitic acid, but other fatty acids (monounsaturated (MUFA) and polyunsaturated) are presented at low concentrations. In the processing plant some high amount of oleic acid with some other unsaturated fatty acids are extracted and marketed as Palm olein oil, and used to reduce blood or egg cholesterol (Rievelles et al., 1994). The objective of this study was to determine the optimum level of dietary palm olein oil required to enrich the mono-unsaturated fatty acid content of yolk, egg cholesterol and antibody titre.

Teff and amaranth are gluten-free cereals with significant nutritional and health benefits. However, they are underutilized and known in limited areas of the world. The present study evaluated the fatty acid profile, crude fat, squalene content and lipid quality of seven teff (Eragrostis teff (Zucc.) Trotter) and three amaranth (Amaranthus caudatus L.) varieties from Ethiopia. The fat content ranged from 2.92 to 3.34% (averaging 3.06%) and from 8.28 to 9.21% (averaging 8.6%) for teff and amaranth, respectively. Linoleic, oleic and palmitic acid were predominant in both teff and amaranth, accounting for approximately 89 and 85% of total fatty acid content, respectively. The saturated to unsaturated fatty acids ratio ranged from 0.30 to 0.32 in teff and from 0.38 to 0.40 in amaranth. The parameters used to describe lipid quality, i.e., thrombogenicity and atherogenicity indices, show that teff was superior over amaranth, suggesting a preference for the former for healthy food formulation. The squalene content of white amaranth (486.54 mg/100 g DM) was significantly higher than that of the other two varieties (327.54 and 340.81 mg/100 g DM for red and brown amaranth, respectively). In general, both gluten-free crops should be exploited for their potential as ingredients for the development of novel functional foods.
