The production of ecologically clean fish products is in demand in the food market. As a result of the research, the nutritional quality and chemical composition of the muscle tissue of the Nile tilapia (Oreochromis niloticus L.) were evaluated using the pro-biotic additive Enzimsporin. A valuable quality of Nile tilapia meat is its high protein content. In the muscle tissue, the maximum amount of protein was 80.4%, in the yearlings of the 1st experimental group, which is 7.51% (P ≥ 0.99) higher than in the control group. Yearlings of the 2nd experimental group outperformed their peers from the control group by 4.8% (P ≥ 0.95). Its amount in fry of Nile tilapia varied from 72.27–72.73% in the experimental groups to 74.71% in the control group. The fat content in fry varied from 9.55% in the control to 12.19% in the fish of the 2nd experimental group. The amount of lipids was the highest in the control variant of Nile tilapia yearlings (11.48%), which is 6.48% more than in the 1st experimental group and by 4.48% more than that in the 2nd experimental group. The lipid-protein coefficient (0.06-0.09) of the experimental groups characterizes the meat as less tender, but high in protein, possessing lipotropic properties that protect the liver from fatty infiltration. The study of nutritional value and functional and technological properties shows that tilapia meat can be attributed to highly saturated food raw materials and used to obtain dietary products.

Objective of this paper was to evaluate phenotypic variability of carcass side traits and quality of meat of fatteners (male castrated heads) of Moravka breed (M) and Mangalitsa (swallow-belly Mangalitsa - LM). The quantity and content of meat were determined based on dissection of left carcass sides (Walstra and Merkus, 1996). Also, nutritive properties of musculus longissimus dorsi (m.l.d.) were established. Obtained data were processed using GLM procedure of the program package SAS 9.1.3 (SAS Inst.Inc., 2002-2003). Results of the study show that Moravka fatteners had longer carcass sides (+6.82 and + 5.00 cm) compared to Mangalitsa breed, corrected to average body weight at slaughtering. Fatteners of M breed had in average higher total mass of back-loin part (+0.685, P<0.05) and average quantity of muscles in the same part of carcass side (+0.631 kg, P<0.01), compared to fatteners of LM breed. Also, they had higher quantity of muscle in belly-rib part (+0.237 kg, P<0.05) compared to LM. Share of muscle tissue in back-loin and belly-rib carcass side parts corrected for WCC, was higher in M carcass sides than in LM (P<0.01). Conversely, muscle tissue content in shoulders of Mangalitsa was higher (+4.8% ; P<0.05) than in Moravka. Share of muscle tissue in carcass sides of M pigs was by 4.3% higher compared to LM carcass sides. In m.l.d. of Moravka water content was higher (+6.1%, P<0.01), content of total lipids (-6.5%, P<0.05) and cholesterol (-19.68 mg/100 g, P<0.001) was lower than in Mangalitsa.

We aimed to assess the quality of charcoal from three Eucalyptus and Corymbia citriodora species for energy production in the South of Tocantins state. A hybrid Eucalyptus urophylla x Eucalyptus grandis, the species Eucalyptus urophylla, Eucalyptus camaldulensis, and Corymbia citriodora were selected for the study. In the preparation of the material, 20 specimens of each species with the dimensions of 2.0 x 2.0 x 5.0 cm were made, being ten repetitions for each carbonization gait with different final temperatures and heating rates. The basic wood density, total gravimetric yield, total yields in condensable and non-condensable gases, immediate chemical analysis, and higher calorific value were determined. Corymbia citriodora presented higher wood basic density (0.583 g/cm³) and charcoal apparent density (0.459 g/cm³). In immediate chemical analysis, Eucalyptus urophylla and Corymbia citriodora presented the best averages among all species. The calorific value ranged from 7235.97 to 7573.98 (kcal/kg), considered an acceptable value for energy production. The final carbonization temperature of 550°C is recommended, with Eucalyptus urophylla and Corymbia citriodora presenting the best averages.

In Russian market of meat products production of poultry meat occupies more than 47 %. At the same time, the share of poultry products in the total volume of animal protein consumed is 42,1 %, including poultry meat – 27,8 %, eggs – 14,3 %. The quality of the resulting meat is significantly influenced by feeding (feed ingredients, biologically active additives). The purpose of the investigations was to study the influence of compound feed containing Camelina presscake on the chemical composition of broiler muscle tissue. The investigations have been carried out on the basis of the Siberian Scientific and Research Institute of Poultry Farming – a branch of the Federal State Budgetary Scientific Institution “Omsk Agricultural Research Center” (Morozovka village, Omsk region) on broiler chickens of the cross Sibiryak-2. The results of the investigations on the influence of compound feed with Camelina presscake obtained from seeds of the Siberian selection on the qualitative composition of the muscle tissue of broilers have been presented in the article. The research has been conducted on four groups of broiler chickens from 1 to 42 days of age, in each group there were 100 heads. Camelina presscake was introduced instead of another traditional protein feed to the 1st experimental group – 12,5 %, the 2nd – 15 % and the 3rd experimental group – 20 % with the preservation of the total energy and protein nutrition of the compound feed. It has been found that in the muscles of broiler chickens of the experimental groups the protein content was higher by 0,06–0,73 abs.%, fat by 0,03–0,57 abs.%, energy nutrition higher by 0,03–0,29 MJ/kg. When comparing the amount of macro- and microelements in muscle tissue, the advantage has been noted for most of the studied indicators of poultry of experimental groups that received compound feed with Camelina presscake.

Abstract Background Thalassemia have a negative impact on the patients' psychological health and sleep quality. This study aimed to determine the effects of a positive thinking training program on hope and sleep quality of patients with thalassemia major. Methods This randomized clinical trial was conducted on 78 patients with thalassemia major including 36 males (46.2%) and 42 females (53.8%) with a mean age of 25.56 ± 29.6 in Iran. Subjects were randomly assigned into experimental and control groups. Experimental group received 16 h training based on positive thinking materials published by Martin Seligman. Control group received only usual programs. Data were collected at baseline, as well as immediately and one month after the intervention, using Snyder’s Hope Scale and the Pittsburgh Sleep Quality Index. Data analysis was performed using SPSS Software 18.0; statistical tests included the independent T-test, the Chi-square, Mann Whitney, and Friedman test. Significance level was set at 0.05 in this study. Results The experimental group had a significantly higher mean hope score compared to the control group immediately (45.38 ± 7.82 vs. 35.32 ± 5.54, P < 0.001) and one month following intervention (44.67 ± 3.47 vs. 35 ± .54, P < 0.001). Moreover, the mean sleep quality scores of the experimental group was significantly greater than that for control group immediately (5.35 ± 2.02 vs. 7 ± 2.4, P = 0.004) and one month after the intervention (4.23 ± 2.2 vs.7.02 ± 3.03, P < 0.001). Conclusion Since our training program on positive thinking improved hope and quality of sleep in patients with thalassemia major, we recommend the use of such courses as an important step toward promotion of hope and sleep quality among these patients.

The influence of different drying methods on physical and nutritional properties of shrimp meat was investigated in this study. Peeled shrimps were dried separately using an air-oven dryer and a tunnel solar dryer. The drying profile of shrimp meat was determined in the two drying systems by monitoring moisture loss over the drying period. Changes in color, proximate composition, and rehydration capacity were assessed. The rate of moisture removal during solar drying was faster than the air-oven drying. The development of red color during drying was comparable among the two methods, but solar-dried shrimps appeared darker (L⁎=47.4) than the air-oven-dried (L⁎=49.0). Chemical analysis indicated that protein and fat made up nearly 20% and 2% (wb) of the shrimp meat, respectively. Protein and ash content of shrimp meat dried under the two dryer types were comparable but fat was significantly (p<0.05) higher in oven-dried meat (2.1%), compared to solar-dried meat (1.5%). Although rehydration behavior of shrimp from the two drying systems followed a similar pattern, solar-dried shrimp absorbed moisture more rapidly. The results have demonstrated that different approaches to drying may affect the physical and nutritional quality of shrimp meat differently.

The physical and chemical characteristics of the fruit have immense significance as they ultimately affect the quality of processed productsprepared from them. Over ripening of Sapota (Manilkara zapota) fruits at the post-harvest stage usually results in dramatic decline in quality.In the present study, physico chemical analysis (which includes Weight loss, Colour, Texture, TSS, pH, TA and Ascorbic acid content) ofedible Aloe vera gel coated Sapota fruits packed in LDPE and stored at 15 ± 2? were studied at regular intervals of 5 days i.e., 0th,5th, 10th,15thand 20th days. The dip treatment of Aloe vera gel coating 1:2, 7 minutes had best retained the physico chemical characteristics than the othertreatments performed and was found to be the most effective treatment in maintaining the fruit quality attributes along with the shelf lifeextension of about 20 days.DOI: http://dx.doi.org/10.3126/ijasbt.v3i1.11703 Int J Appl Sci Biotechnol, Vol. 3(1): 20-25
