| Abstract The present study aims to evaluate the influence of extraction methods on the quality of bioactive compounds and antioxidant capacity in Pterodon emarginatusVogel (sucupira) oils. The oils were extracted from the sucupira seeds by Soxhlet and by the extraction system of Bligh & Dyer. The oils were analyzed as to fatty acid profile, tocopherols, phytosterols, carotenoids, total phenolics, and total antioxidant capacity. The extraction by Soxhlet showed better yield of total lipids and was more efficient to extract tocopherols, phytosterols, and carotenoids, besides presenting better antioxidant activity by DPPH•. However, this method showed insufficient capacity to extract the polar lipid components of the sample, as evidenced by the low... |

| ABSTRACT The adulteration of dead chicken meat with halal meat is a concern in Pakistan that can harm safety of meat as well as religious beliefs of the Muslims. Accordingly, the present study was conducted to evaluate slaughtering methods (Islamic and decapitation) with dead chicken meat on composition, quality and safety attributes. Purposely, (n=24) birds were slaughtered and (n=12) dead birds samples were collected and subjected to proximate, mineral and quality analysis including pH, color (L*, a*, b*), cooking loss, texture, as well as thiobarbituric acid reactive substances (TBARS), peroxide value (PV), haem and non-haem iron. The results indicated ash content, minerals and oxidation parameters including TBARS, PV affected significantly (p<0.05).... |

| Abstract: The objective of this work was to evaluate the influence of the inclusion of soybean (Glycine max) gum in the diet of laying hens on egg production, egg external and internal quality, and economic viability, as well as of temperature and storage time on the oxidative stability of eggs. One hundred and eighty 40-week-old Lohmann-LSL layers were fed 0, 1, 2, 3, 4, and 5% soybean gum in the diet. In the economic analysis, the average productive performance of the layers and the cost of feed were considered. In order to evaluate oxidative stability, eggs were stored at room temperature (~30oC) or refrigerated (5oC) for 0, 7, and 21 days. The inclusion of soybean gum in the diet increased feed intake and also egg production, average weight, and mass.... |
