In present study, the usability of chitosan and gelatin (1:1) films incorporated with green tea extract (GTE) to improve the shelf life of the chicken meat stored in chilled condition was evaluated. The extract of green tea was evaluated for its phenolic content, antioxidant activity and ferric ion chealating ability. The ChGel films possessed antimicrobial activity and inactivated approximately 3 log cfu/ ml of K. pneumoniae, S. typhi var. Weltevreden, S. typhi var. Oslo, Y. enterocolitica, E. feacalis, B. cereus, E. coli and S. aureus in 3 hours. Incorporation of GTE influenced the optical and mechanical properties of the films. Chicken samples without films were observed to be microbiologically safe for not more than 6 days, while ChGel and ChGel-GTE films improved the microbial safety of chicken samples till day 13. ChGel-GTE films also prevented lipid peroxidation in samples as evident by TBARS value (day 10: control: 1.14; ChGel-GTE: 0.21 mg MDA eq/kg). Protein oxidation during chilled storage of chicken was also prevented by ChGel-GTE by inhibiting protein carbonylation, loss of free thiols groups in protein and lowering the number of disulphde bonds. This study supports use of ChGel films with GTE for enhancing the safety of stored chicken meat not only by maintaining the microbial quality of the samples but also preventing oxidative changes which can hamper the functional, nutritional and sensorial properties.

Показана эффективность использования в рационах промышленных кур-несушек натуральных кормовых добавок, изготовленных из сырья растительного происхождения (элеутерококка колючего, морской бурой водоросли, патринии скабеозолистной, крапивы двудомной, муки из шелухи шишек кедрового ореха). Выявлено положительное влияние кормовых добавок на обменные процессы в организме кур, что способствовало повышению их производительных качеств и снижению коэффициента конверсии корма. The results of effective use of the spiny eleuterococcus, brown seaweed, Dahurian patrinia, common nettle, flour from pine cone shell as the feed supplement from raw materials of plant origin in addition to the main ration of industrial laying hens are presented in this publication. The positive influence of the feed supplements on metabolic processes in the hen organisms was discovered and this fact contributed the increase of productive qualities and improvement of feed conversion.

Thirty red deer (Cervus elaphus) stags were slaughtered at three deer slaughter premises (plants A, B, and C) to determine the effects of initial microbial flora on the quality of chilled venison loins stored using three packaging methods: vacuum packaging (VP), modified atmosphere packaging using an ultra-high barrier outer barrier film (CO2-UHB), and modified atmosphere packaging using a dual aluminized polyethylene outer barrier film (CO2-MPET), all of which were stored for 6, 12, and 18 weeks at −1 ± 3°C. Carcasses slaughtered in plant B had higher aerobic plate counts than those killed at either plants A or C. Location of slaughter had little effect on loin quality except for drip loss, pH and anaerobic and lactic acid bacteria counts. Oxygen levels increased in the modified atmosphere packages (P<0.05) during storage from 12 to 18 weeks (CO2-UHB, 1%; CO2-MPET, 0.05%). Loins packaged in CO2 -UHB exhibited less acceptable surface color than meat packaged in CO2 -MPET or VP. Aroma, flavor, texture, and acceptability scores decreased (P<0.05) when loins were stored over 12 weeks regardless of packaging method. pH values of loins packaged in modified atmosphere packs were lower (P<0.05) than those in VP. The regression relationship between percent drip loss and pH was given by % drip = 39.1–6.49 [Standard error (SE) 1.52] pH. Acceptable display color of steaks cut from the loins, regardless of treatment, decreased as loins were stored from 6 to 18 weeks. These results suggest that vacuum packaged venison loins resulted in meat of acceptable quality after 12 and 18 weeks of chilled storage, and that modified atmosphere packaging contributed no additional benefit.

Stimulating Factor

Immunosuppression derived after cytostatics application in cancer chemotherapy is considered as an adverse side effect that leads to deterioration of quality of life and risk of infectious diseases. A linear sulfated (1→3)-α-l-fucan M-Fuc prepared by chemical modification of a fucoidan isolated from the brown seaweed Chordaria flagelliformis, along with two structurally related synthetic sulfated oligosaccharides, were studied as stimulators of hematopoiesis on a model of cyclophosphamide immunosuppression in mice. Recombinant granulocyte colony-stimulating factor (r G-CSF), which is currently applied in medicine to treat low blood neutrophils, was used as a reference. Polysaccharide M-Fuc and sulfated difucoside DS did not demonstrate significant effect, while sulfated octasaccharide OS showed higher activity than r G-CSF, causing pronounced neutropoiesis stimulation. In addition, production of erythrocytes and platelets was enhanced after the octasaccharide administration. The assessment of populations of cells in blood and bone marrow of mice revealed the difference in mechanisms of action of OS and r G-CSF.
