An experiment was conducted to investigate the effects of dietary supplementation of Rhodobacter capsulatus KCTC-2583 on egg-yolk and serum cholesterol, egg production and quality parameters during the late laying periods in hens. A total of 160 Hy-Line Brown layers (54 wk-old) were randomly allotted to 4 treatment groups on the basis of laying performance. Each treatment had 4 replicates with ...

Dietary lutein intake is postulated to interfere with the development of age-related macular degeneration (AMD). Because egg yolk-derived lutein has a high bioavailability, long-term consumption of lutein-enriched eggs might be effective in preventing AMD development, but alternatively might increase cardiovascular disease risk. Here, we report the effect of 1-y daily consumption of a buttermil...

To elucidate whether Sterol O-acyltransferase (Soat) mediates the absorption and transportation of yolk lipids to the developing embryo, zebrafish soat1 and soat2 were cloned and studied. In the adult zebrafish, soat1 was detected ubiquitously while soat2 mRNA was detected specifically in the liver, intestine, brain and testis. Whole mount in situ hybridization demonstrated that both soat1 and ...

This study was conducted to investigate the cholesterol-lowering property of garlic (Allium Sativum) in whole blood of egg yolk induced hypercholesterolemia in rabbits. Forty rabbits of both sexes of 13.1 ± 28.4 weeks of age with average body weights of 1251.9 ± 512.2g were used for the experiment. The animals were divided into eight groups comprising control and seven experimental groups with ...

This study aimed to evaluate the effects of dietary egg yolk phosphatidylcholine (EPC) and soybean (SPC) on obesity mice fed a high-fat diet (HFD). After 60 days intervention, were evaluated by biochemical indices serum lipidomic analysis. EPC SPC markedly reduced total cholesterol, triacylglycerol (TAG) low-density lipoprotein while increased high-density cholesterol. was more effective in red...

In this study, 162 students in the 6 year Pharmacy Program at the School of Pharmacy, Iwate Medical University were asked to prepare liposomal preparations using chicken egg yolk and to evaluate their properties with the aim of developing novel liposomes. High-purity lecithins are generally used for preparing liposomes but they are expensive. On the other hand, egg yolk has various components, ...

Membrane separation technology is achieving broad applications in research, food and pharmaceutical industry. In this study, the application of UV-VIS-NIR spectroscopy to quantify composition fractions obtained a membrane process was assessed. An egg filtration employed as case study develop predictive models for rapid determination dry matter, protein cholesterol feed (retentate filtrate). Who...

Č������ H., V������� M., P���������� V., K�������� F. (2004): Determination of egg yolk content in egg liqueurs. Czech J. Food Sci., 22: 9–15. The recent Czech Food law (Decree No. 264/2003, 93/2000 and 57/2003 of the law No. 110/1997 as amended) requires the minimal concentration of egg or egg yolk content in relevant food products (mayonnaises, egg pastas, egg liqueurs), however, the methods ...
