    Probiotic administration of Litopenaeus vannamei: Is there any negative effect on the fatty acid profile of meat? (2018)
    Details
    Publikationsdatum: 2021-05-19
    Beschreibung: It has been found that appropriate probiotic applications increased growth performance and disease resistance in shrimp. Bacillus subtilis has been suggested as a potent probiotic in improving growth performance and enhancing immune response in white shrimp, Litopenaeus vannamei. The aim of this work was to evaluate the possible effect of B. subtilis administration on the meat fatty acid profile of white shrimp, L. vannamei. Two groups of shrimps received B. subtilis strains L10 and G1 from the B. subtilis-supplemented feed (105 and 108 CFU g-1) while two other groups received it from the rearing water (105 and 108 CFU ml-1). One group received no B. subtilis and served as control. According to the results, there was no significant difference between the muscle fatty acid profiles of shrimps administrated by probiotic and control group. This study showed that B. subtilis administration, in either diets or water, did not have any negative effect on fatty acid profiles of L. vannamei meat.

    Proximate and fatty acid composition of liver and fatty tissue of patincatfish (Pangasianodon hypophthalmus) (2018)
    Details
    Publikationsdatum: 2021-05-19
    Beschreibung: The visceral storage fat and liver of patin catfish (Pangasianodon hypophthalmus) are normally discarded, which incurs cost and can cause environmental pollution. However, these may be potential sources to extract fish oil. The proximate and fatty acid compositions of liver and fatty tissue of patin catfish were investigated to evaluate the suitability of these by-products for extracting fish oil. Fat was extracted using a low temperature solvent extraction method. The average fat content of fatty tissue and liver of females were 77.64 and 11.71%, respectively, whereas in males this was73.23 and 9.59%, respectively. Fatty acids found in the extracted oil of these byproducts were C12:0, C14:0, C14:1, C16:0, C16:1, C18:0, C18:1, C18:2, C18:3, C18:4, C20:0, C20:1, C20:4, C20:5, and C22:6.The major fatty acids presented in these tissues were palmitic (C16:0), oleic (C18:1n-9), and linoleic acid (C18:2 n-6). The total amount of polyunsaturated fatty acids of liver from male and female patin catfish were 13.31 and 13.30%, respectively, whereas in the fatty tissue these were11.64 and 12.09%, respectively. The n-3 to n-6 ratios of liver and fatty tissue of females were 1.61and 0.95, respectively, whereas in male fish these were 1.31 and 1.05, respectively. Results of this study indicated that the liver and fatty tissues of patin catfish are suitable sources of fish oil specifically due to the presence of monounsaturated and n-3 polyunsaturated fatty acids.

    Effect of using various amounts of patin (Pangasianodon hypophthalmus) fish oil on physical and chemical properties of moisturizing hand cream (2019)
    Details
    Publikationsdatum: 2021-05-19
    Beschreibung: Hand cream is used for rehydrating and improving skin properties. The skin is the first point of contact with the environment. Thus having healthy skin with proper barrier properties is quite important. The beneficial effects of fish oil on skin make it a favorable ingredient to be used in hand care products. In the present study, the efficacy and stability of various hand cream formulations using 0, 1.0, 2.5 and 5.0% of fish oil were investigated and compared. The appearance, odor, texture, and pH of formulations containing 1 and 2.5% of fish oil remained stable in very good qualities during the storage, whereas the related values to the appearance and texture of formulation containing 5.0% of fish oil at the end of 6 months of storage at 45°C were significantly (p〈0.05) lower than other formulations and previous evaluations of this formulation. Weight loss was not observed in all formulations under study.

One group received no B. subtilis and served as control. According to the results, there was no significant difference between the muscle fatty acid profiles of shrimps administrated by probiotic and control group.

    Effect of dietary linolenic acid (18:3n–3)/linoleic acid (18:2n–6) ratio on growth performance, tissue fatty acid profile and histological alterations in the liver of juvenile Tor tambroides (2021)

    Beschreibung: This study was conducted to determine optimal ratios of dietary linolenic acid (18:3n-3, LnA) to linoleic acid (18:2n-6, LA) for Tor tambroides. Juveniles were fed three trial diets with different ratios of LnA/LA (0.0, 0.5 and 1.0) for 10 weeks. Another diet contained 100% palm oil, which was similar to the diet with 0.0 LnA/LA ratio but different in total amounts of C18 polyunsaturated fatty acid, was also used as a control. At the end of the experiment, no significant difference in growth performance was observed among treatments. The overall fatty acid composition in muscle of T. tambroides fed experimental diets was similar in terms of saturated fatty acid and monounsaturated fatty acid. The muscle of fish fed diet with LnA/LA ratio of 0.0 contained significantly lower (p〈.05) amount of overall n-3 PUFA than those fed the other diets. Intense accumulation of lipid in the liver parenchyma of all fish except for those fed control diet led to severe degeneration of hepatocytes indicating fatty liver. However, most of the hepatocytes of fish fed control diet were also swollen with nuclei migrated. T. tambroides fed diet with LnA/LA ratio of 0.0 showed degenerated enterocytes with an epithelium with disrupted edges. In conclusion, using vegetable oils contained high level of either LA or LnA in T. tambroides diet seemed to have no advantage over using palm oil contained high level of saturated fatty acid.

    Refined oil production from patin catfish (Pangasianodon hypophthalmus) by-products (2018)
    Details
    Publikationsdatum: 2021-05-19
    Beschreibung: In this study, oil was extracted from the liver and visceral fat of Patin (Pangasianodon hypophthalmus) and refined. The yield of oil after refining was 49.98%. The major yield loss (34.20%) happened during the degumming procedure. Fatty acids found in the crude and refined oil were C12:0, C14:0, C14:1, C16:0, C16:1, C18:0, C18:1, C18:2, C18:3, C18:4, C20:0, C20:1, C20:4, C20:5, and C22:6. The dominant saturated, monounsaturated and polyunsaturated fatty acids were C16:0, C18:1 n-9, and C18:2 n-6, respectively. The total amounts of monounsaturated fatty acids did not change significantly during refining procedure (p〉0.05), whereas the total amount of saturated and polyunsaturated fatty acids changed significantly (p〈0.05). The n-3 to n-6 ratios of crude, degummed, neutralized, bleached, and deodorized oils were 1.11, 1.06, 1.05, 1.02, and 1.01, respectively.
