– terpene/terpenoid compounds, their isomers and derivatives, flavonoids and other biologically active natural substances. The aim of this work was to study the effect of cinnamon oil extract on the accumulation of histamine in canned fish during storage. 2 Materials and methods 2.1 Samples Three fish species were used for the preparation of canned samples – Pacific herring ( Clupea harengus pallasi ), Pacific pink salmon ( Oncorhynchus gorbuscha ), and Pacific mackerel ( Scomber japonicиs ). The choice of these fish species was made due to the fact that their muscle

Abstract

The bacterial translocation induced by colitis may cause the organ failure and sepsis. Therefore, it is necessary to find new possibilities for prevention and therapy of this problem. The purpose of this study was to examine Escherichia coli anti-translocation activity of cinnamon oil and its ability to reduce colonic damage in mice with TNBS (2,4,6-trinitrobenzenesulfonic acid) induced colitis. Mice received cinnamon essential oil in four various concentrations (0.5%, 0.25%, 0.125% and 0.063%) in the powdery commercial rodent diet, starting 21 days before induction of TNBS colitis. The colonic damage was assessed using the colon macroscopic scoring system (Wallace score). E. coli translocation to the mesenteric lymphatic nodules was evaluated by serial dilutions method for counting bacteria. Bacterial translocation was significantly reduced in first and third group (15.2% or 42.8% in cinnamon oil groups versus 100% in TNBS group). Cinnamon oil was effective also against the colonic damage in all cinnamon oil groups (macroscopically scores of grade 9 in TNBS group versus 5.25, 5.63, 5.13 and 3.25 in cinnamon oil groups). Our results confirmed that dietary administration of cinnamon oil could possess potential therapeutic effects on bacterial translocation and intestinal wall injury in colitis.

Abstract

The aim of the study was to test whether the use of probiotic bacteria Bacillus subtilis or Enterococcus faecium or a phytobiotic containing cinnamon oil can improve the metabolic parameters, immune status, gut microbiota and histology, and growth performance of broiler chickens. The experiment was carried out on 560 one-day-old male Ross 308 broiler chickens raised until the age of 42 days. The broiler chickens were assigned to 4 experimental groups of 140 birds each (7 replications of 20 individuals each). The control group (Control) did not receive additives. A probiotic preparation containing live bacterial cultures of Enterococcus faecium (EF, in the amount of 0.25 g/l) or Bacillus subtilis (BS, 0.25 g/l) or a phytobiotic preparation containing cinnamon oil (OC, 0.25 ml/l) was administered to the broiler chickens with their drinking water throughout the rearing period. The most important results indicate that the use of BS and OC resulted in: a significant (P≤0.05) increase in the level of ferric reducing ability of plasma (FRAP), high-density cholesterol (HDL) and glutathione (GSH + GSSH) and a significant (P≤0.05) decrease in the level of malondialdehyde (MDA), lipid hydroperoxides (LOOH), total cholesterol (TC), triacylglycerols (TAG), nonesterified fatty acids (NEFA) and interleukin 6 (IL-6), a ratio of heterophils : leukocytes (H:L) and alkaline phosphatase (ALP) activity, alanine aminotransferase (ALT), acidic phosphatase (AC) and creatinine kinase (CK), relative to the C group. In the blood of broiler chickens from the OC treatment, aspartate aminotransferase (AST), lactate dehydrogenase activity and 3-hydroxy-butyrate dehydrogenase (HBDH) significantly (P≤0.05) decreased in relation to the C group, and in broiler chickens from EF and BS treatments there was an increase (P≤0.05) in haemoglobin (Hb) content. Compared with group C, in the broiler chickens’ nutritional content from EF, BS and OC treatments, the total number of coliforms and number of fungi significantly (P≤0.05) dropped and the number of aerobic bacteria increased (P≤0.05) in the length of the villus and the depth of the crypt. It has been found that Bacillus subtilis, Enterococcus faecium and phytobiotic containing cinnamon oil can improve the microbiological and histological appearance of broiler chicken intestine. The addition of probiotic bacteria Bacillus subtilis or phytobiotic containing cinnamon oil to drinking water is more preferable than Enterococcus faecium regarding stimulation of the immune system, blood redox status parameters, parameters of metabolic changes and the gut microbiome and morphometry.

Abstract

The aim of the present research work was to investigate the effect of orange and cinnamon oil on the occurrence and harmfulness of Thrips tabaci Lind on onion. In 2014, the nonchemical treatment was made with Prev-B2 (the concentration of 0.4%), which contains: 4.2% of orange oil, 2.1% of boron and product Canol 70% p/p exstract of Cinnamomum zeylanicum. In 2015, only Prev-B2 product was used. The standard sprayer was used and the treatments were done: twice in 2014 and three times in 2015. The thrips were collected directly from the leaves, using standard sweeping nets. The plants were examined to find the leave damages caused by feeding thrips. In 2014, Thrips tabaci was recorded from 11 June to 19 August, whereas in 2015 from 24 June to 4 August. Over two years of observations, the highest number of thrips was collected from onion growing on control plots (not treated with any preparation). Also, the mean percentage of areas damaged on the onion leaves was significantly higher on control plots than on plots treated with cinnamon oil in 2014 and orange oil in 2015.

-loaded liposome. Flavorings such as cinnamon oil (CO) are effective at masking the off-flavor of fish oils. CO is also antimicrobial and an antioxidant, which are useful traits for food packaging systems [ 4 , 24 ]. Therefore, we have attempted to encapsulate FO through LbL electrostatic deposition by using a nonionic emulsifier (Tween 20, TW20), a cationic biopolymer (chitosan, CHI), and an anionic biopolymer (LMP) to form the interfacial membranes. In addition, we developed formulations of multilayered FO emulsions containing CO for use in food systems in future studies. Our
