Alterations in multiple molecular forms of enzymes have been described during normal embryogenesis. Changes in electrophoretic patterns, which differ from the normal isozyme ontogeny, occur in embryos and their yolk-sacs during incipient maldevelopment secondary to teratogen exposure. One such isozyme change, in response to a teratogenic regimen using 9-methyl pteroylglutamic acid (PGA), is per...
The developmental fate of the vitellogenin-derived yolk protein, lipovitellin (Lv), was investigated in winter flounder embryos and yolk-sac larvae. Since Lv is present as only one major polypeptide in ovulated winter flounder eggs, unlike the multiple yolk polypeptides found in the mature eggs of most teleosts, this system is presented as a simpler model of yolk protein structure and utilizati...
Formulation of insulin into a microemulsion very often presents a physicochemical instability during their preparation and storage. In order to overcome this lack of stability and facilitate the handling of these colloidal systems, stabilization of insulin in presence of hydrophobic components of a microemulsion appears as the most promising strategy. The present paper reports the use of egg yo...
High oxidative capacity of polyunsaturated fatty acid rich oils is the main problem with their dietary application. The main objectives of this study were to determine the effects of different encapsulants and oil loading levels on nutritive value, fatty acid profile, and oxidative stability of microencapsulated fish oil powders. Four types of wall materials [glucose syrup and maltodextrin base...
Adding supplements to hen feed can increase egg nutritional value. Astaxanthin, tocotrienols, and tocopherols are potent antioxidants that provide health benefits to humans. We hypothesized that the addition of these nutrients to hen feed would result in an increased nutrient content in egg yolk with minimum changes in functional properties. Laying hens (Hy-Line W-36 breed) were fed four diets ...
TABLE I report that specially processed soybean oils containing little or no linolenate gave higher scores in aging tests than soybean oils with linolenate contents of 2.0-7.8. Room odor scores and descriptions were included in this report (4). Consequently blends of soybean and peanut oil appeared to be worth investigating since such blends could lower linolenate significantly. The French laws...
