In this study, rosemary and thyme oil extracts obtained using trout (Oncorhynchusmykiss) marinades of the chemical changes that occur during storage was investigated and effect on fatty acid composition of vegetable oil extracts used in the product are determined. Using three different formulations are made into fish fillets (M: 4% acetic acid-10% NaCl-0.1%, B: 4% acetic acid-10% NaCl-0.1% of rosemary oil extract, K: 4% acetic acid - 10% NaCl-%0.1 thymol oil extract) was marinated, after the maturation stage vacuum packaged at +4°C in the refrigerator conditions have been stored. Samples; 0 days 1, 2, 3, 4 and 5 at the end of the month chemical analysis (pH, TBA, peroxide value, TVB-N, free fatty acids, fatty acid composition) were conducted. Experimental samples were evaluated in term of TVB-N determined M group samples 28.9 mg/100 g, B group samples19.2 mg/100 g and K group samples 14.12 mg/100 g in the third month of storage. When the samples of M group were evaluated in terms of TBA number, it was 5.84 mg MDA / kg at the 3rd month of storage and statistical difference was found to be significant with the other groups. The control group (M group) samples analysed were not performed for sensory deterioration at 4 and 5 months. After marination, the control group and K group samples decreased EPA and DHA during storage period, it was found statistically significant difference. When the fatty acid values of the samples belonging to the group containing rosemary were examined, caproic, myristic and palmitic acid amounts increased after the marinate and difference statistically significant.

Physical And Chemical

The effect of a dietary linseed (Linum usitatissimum L.) supplement on the traits of fattening, carcass value, physical and chemical characteristics of meat quality, and the fatty acid composition of pig meat was evaluated. Seventy-two hybrids (Czech Large White <sub>(paternal)</sub> &times; (Czech Large White <sub>(maternal)</sub> &times; Czech Landrace)) were divided into four treatments according to diet (0 and 150 g/kg linseed) and sex (barrows and gilts). A significantly (P = 0.050) higher feed conversion value was ascertained in barrows fed with linseed compared with the other three groups. Most of the physical and chemical characteristics of the carcasses were not significantly influenced by dietary linseed addition or sex. The linseed supplement significantly (P &lt; 0.001) increased the polyunsaturated fatty acid (PUFA) content and PUFA/SFA (saturated fatty acid) ratio, especially through increasing the n-3 PUFA content, and decreased the monounsaturated fatty acid (MUFA) content, the MUFA/PUFA, MUFA/SFA, and n-6/n-3 PUFA ratios and the thrombogenic index. Supplementation of the diet with linseed modified the fatty acid composition and improved fatty acid ratios in both sexes, without any negative effect on performance, carcass value or physical and chemical indicators of pig meat quality.

Growth And Yield

Salinity stress is a limiting factor for the growth and yield quality of rapeseed. The potentiality of melatonin (MT; 0, 25, 50, and 100 µM) application as a seed priming agent in mediating K+/Na+ homeostasis and preventing the salinity stress mediated oxidative damage and photosynthetic inhibition was studied in two rapeseed cultivars. We found that 50 µM MT treatment imparted a very prominent impact on growth, metabolism of antioxidants, photosynthesis, osmolytes, secondary metabolites, yield, and fatty acids composition. Days required for appearance of first flower and 50% flowering were decreased by MT application. Exogenous MT treatment effectively decreased the oxidative damage by significantly declining the generation of superoxide and hydrogen peroxide under saline and non-saline conditions, as reflected in lowered lipid peroxidation, heightened membrane stability, and up-regulation of antioxidant enzymes (catalase, superoxide dismutase, and ascorbate peroxidase). Furthermore, MT application enhanced the chlorophyll content, photosynthetic rate, relative water content, K+/Na+ homeostasis, soluble sugars, and proline content. Moreover, MT application obviously improved the oil quality of rapeseed cultivars by reducing glucosinolates, saturated fatty acids (palmitic and arachidic acids), and enhancing unsaturated fatty acids (linolenic and oleic acids except erucic acid were reduced). Yield related-traits such as silique traits, seed yield per plant, 1000 seeds weight, seed oil content, and yield biomass traits were enhanced by MT application. The anatomical analysis of leaf and stem showed that stomatal and xylem vessels traits are associated with sodium chloride tolerance, yield, and seed fatty acid composition. These results suggest the supportive role of MT on the quality and quantity of rapeseed oil yield.
