Resumo
The effect of sunflower oil (SO), sunflower oil-pomegranate sauce (PS1) and sunflower oil-plum sauce (PS2) on shelf life of marinated carp fillets was investigated in terms of sensory evaluation, chemical (peroxide value (POV), thiobarbituric acid (TBA), free fatty acids (FFA), total volatile basic nitrogen (TVB-N) and pH), and microbiological properties (Total viable count (TVC), Escherichia coli, Total coliform, Staphylococci/Micrococci, Salmonella spp.) during 30 days of storage. Proximate composition, which includes total crude protein%, fat%, moisture% and ash% of fresh carp fillets before marination process was analyzed and found 18.69±0.86, 4.08±0.19, 74.33±0.63 and 2.17±0.45, respectively. Sensory evaluation analysis showed that total appearance, odor-taste and texture scores decreased during storage. TVB-N significantly increased in all group after 1 month of storage (P 0.05). At the end of storage, the lowest TBA value (1.38 mg MA/kg carp fillet) was determined in the PS1 group. During storage, the highest POV value was observed in the control group (8.49 mEq O2/kg) compared to other groups. Initial TVC of 1.5 log CFU/g, 1.7 log CFU/g and 1.8 log CFU/g increased to 3.7 log CFU/g, 2.9 log CFU/g and 3.2 log CFU/g in SO, PS1 and PS2 groups, respectively. Results showed that the shelf life of marinated carp fillets treated with sunflower oil and in combination with pomegranate and plum sauce was more than 1 month.(AU)
O efeito do óleo de girassol (SO), molho de óleo de girassol-romã (PS1) e molho de óleo de girassol-ameixa (PS2) na vida útil de filetes de carpa marinados foi investigado em termos sensorial, químico (valor de peróxido (PV), ácido tiobarbitúrico) (TBA), ácidos graxos livres (AGL), nitrogênio básico volátil total (TVB-N) e pH) e propriedades microbiológicas (contagem viável total (TVC), Escherichia coli, coliforme total, estafilococos/Micrococos, Salmonella spp.). Durante 30 dias de armazenamento. A composição aproximada, que inclui % de proteína bruta total, % de gordura, % de umidade e % de cinzas de filés de carpa frescos antes do processo de marinação foi analisada e encontrada 18,69 ± 0,86, 4,08 ± 0,19, 74,33 ± 0,63 e 2,17 ± 0,45, respectivamente. A análise sensorial mostrou que os escores totais de aparência, odor e sabor diminuíram durante o armazenamento. TVB-N aumentou significativamente (P 0,05) em todos os grupos após 1 mês de armazenamento. No final do armazenamento, o menor valor de TBA (1,38 mg MA / kg de filé de carpa) foi determinado no grupo PS1. Durante o armazenamento, o maior valor de POV foi observado no grupo controle (8,49 mEq O2/kg) em comparação com outros grupos. O TVC inicial de 1,5 log CFU/g, 1,7 log UFC/g, 1,8 log CFU/g aumentou para 3,7 log CFU/g, 2,9 log CFU/g, 3,2 log CFU/g nos grupos SO, PS1 e PS2, respectivamente. Os resultados mostraram que a vida útil dos filés de carpa marinados tratados com óleo de girassol e em combinação com molho de romã e ameixa era superior a um mês.(AU)

Background: Respiratory disease negatively affects the physiological performance of racehorses. Inflammatory Airway Disease (IAD) is a typical respiratory disease that affects young horses. The pathogenesis of IAD remains incompletely defined but it is thought to be associated with the inhalation of irritants such as barn dust and air pollution. Although noninfectious agents are likely to be central to the development of IAD, infectious agents can be associated with the disease. The main objective of the present study was to determine the relationships between IAD and antioxidant capacity, ceruloplasmin levels and bacterial and fungal infection status, in racehorses. Materials, Methods & Results: In this study, 25 thoroughbred race horses with exercise intolerance and respiratory system symptoms were evaluated as the study group and 10 healthy horses were included in the control group. Clinical examinations, endoscopic evaluation and tracheal lavage were administered to all horses. Mucus accumulation in the trachea was scored and the horses having a mucus score of ≥ 3 were included the study group. Tracheal lavage fluids were investigated to determine the microbiological status of all animals. In addition, blood samples were collected and total oxidant capacity (TOC), total antioxidant capacity (TAC) and ceruloplasmin (Cp) levels were determined with a spectroscopic method. Exercise intolerance and various respiratory system symptoms such as coughing, nasal discharge and noisy breathing, were the common findings from horses in the study group. Fungal culture was negative and only Streptococcus equi subsp. zooepidemicus strain was isolated from 6 samples. No statistical difference was determined between the TOC, TAC and Cp levels of the groups (P > .05).[...]
